  17. 17. PART II T-SQL ENHANCEMENTS
  18. 18. TABLE-VALUEDPARAMETERS
  19. 19. Table-Valued Parameters• Process a set of rows as a single entity – Similar to temp tables, table variables and CTEs – Example: INSERT an entire order (header & details) with only two parameters and one stored procedure call• Populate a TVP, and then pass it around – It’s a single parameter – Pass from procedure to procedure on the server – Pass from client to server across the network• Based on User-Defined Table Types – Defines the schema, just like an ordinary table – Simply declare a variable as the type to get a TVP• Stored in tempdb – Created and destroyed automatically behind the scenes – Can be indexed
  20. 20. Creating a User-Defined Table Type CREATE TYPE CustomerUdt AS TABLE (Id int, CustomerName nvarchar(50), PostalCode nvarchar(50)) DECLARE @BestCustomers AS CustomerUdt
  21. 21. Table-ValuedParameters
  22. 22. TVP Limitations• TVPs are read-only, once populated and passed – You must apply the READONLY keyword when declaring TVPs in stored procedure signatures – OUTPUT keyword cannot be used – You cannot update, insert or delete• No ALTER TABLE…AS TYPE statement – To change the schema, it must be dropped and re-created – All dependent objects must also be dropped and re-created• Statistics are not maintained on TVPs
  23. 23. MERGE
  24. 24. MERGE• Four statements in one – SELECT – INSERT – UPDATE – DELETE• And even more… – OUTPUT clause – INSERT OVER DML• Operates on a join – Between source and target – Type of join based on merge clause• Start using it now – 100% compatible with existing business logic – Existing triggers continue to work
  25. 25. MERGE Syntax MERGE target USING source ON join WHEN MATCHED UPDATE | DELETE WHEN NOT MATCHED [BY TARGET] INSERT WHEN NOT MATCHED BY SOURCE UPDATE | DELETE ;
  26. 26. MERGE
  27. 27. INSERT OVER DML
  28. 28. DML Output• INSERT, UPDATE, DELETE, and MERGE all support the OUTPUT clause – Captures before-and-after snapshots of modified data via INSERTED and DELETED pseudo-tables (just like triggers) – MERGE adds $action virtual column (returning INSERT, UPDATE or DELETE)• OUTPUT INTO can capture the change data to a table or table variable – Suffers from one limitation – no filtering – Solution – use INSERT OVER DML
  29. 29. INSERT OVER DML Syntax INSERT INTO target(columns) SELECT columns FROM (DML statement with OUTPUT) CHANGES(columns) WHERE filter
  30. 30. DATE AND TIME TYPES
  31. 31. Improved Date and Time Support• Start using these four data types – date – time – datetime2 – datetimeoffset• Stop using these two data types – datetime – smalldatetime• Enhanced storage, portability and functionality – Greater range and precision – More efficient compacted storage – Time zone awareness – All traditional functions support the new types – ODBC, OLE-DB, ADO.NET, SSIS, SSAS, SSRS, Replication
  32. 32. Separate Date and Time Types• Only use what you need – Eliminate extraneous storage when only date or time is needed – Better performance for date-only manipulations and calculations• For example, DECLARE @DOB AS date DECLARE @MedsAt AS time(0)
  33. 33. More Portable Dates and Times• Value ranges align with .NET and Windows• Date Values – From 1/1/0001 (DateTime.MinValue) – Through 12/31/9999 (DateTime.MaxValue) – Legacy datetime type limited to 1/1/1753 through 12/31/9999• Time Values – Up to 100ns (10-millionth of a second) precision – datetime accurate only to roughly hundredth of millisecond, smalldatetime to the minute
  34. 34. Time Zone Awareness• datetimeoffset type – Same range and precision as datetime2• Includes the time zone – Stores an offset ranging from -14:00 to +14:00 – Does not support DST (daylight savings time)• Store local date/time in different regions of the world – Values appear to go in and out as local dates/times• Internally stored in UTC – Automatically converted and treated as UTC for comparisons, sorting and indexing• You append the time zone… – …and SQL Server handles the conversions to and from UTC under the covers automatically
  35. 35. Date/Time Accuracy and Storage• Date values compacted into 3 bytes – One byte less than 4-byte date portion of datetime – Greater range in less space!• Time values consume 5 bytes at most – Supports 100-ns accuracy• Pay less for less – Reduced storage for times that don’t require high accuracy – Specify a scale parameter (0-7) on time, datetime2 or datetimeoffset types – 0 = No decimal precision in 3 bytes – 7 = Greatest decimal precision (100-ns) in 5 bytes – Example: DECLARE @FeedingTime time(0) – Differing scales compatible for comparison
  36. 36. Date and Time Types
  37. 37. T-SQL Enhancements(SQL Server 2012)• Windowing (OVER Clause) Enhancements• New T-SQL Functions in SQL Server 2012• The THROW Statement• Server-Side Paging• The SEQUENCE Object• Metadata Discovery• Contained Databases
  38. 38. Introducing OVER• OVER Clause – Exposes a window over the result set for each row – Added in SQL Server 2005, along with the ranking functions ROW_NUMBER, RANK, DENSE_RANK, NTILE• Can also be used with aggregate functions – SUM, COUNT, MIN, MAX, AVG – Doesn’t require GROUP BY
  39. 39.

  42. 42. Window Partitioning and Ordering• OVER with PARTITION BY – Optionally groups the result set into multiple windows• OVER with ORDER BY – Specifies the row sequence in each window – Required for the ranking functions – Not previously supported for the aggregate functions• Now in SQL Server 2012 – OVER with ORDER BY now supported with aggregate functions – Window “framing” with ROWS and RANGE – Eight new analytic windowing functions
  43. 43. Windowing(OVER Clause)
  44. 44. New T-SQL Analytic Functions• FIRST_VALUE – Returns a column value from the first row of the window• LAST_VALUE – Returns a column value from the last row of the window• LAG – Returns a column value from a previous row of the window• LEAD – Returns a column value from a subsequent row of the window• PERCENT_RANK – Calculate percentile as (RANK – 1) / (N – 1)• CUME_DIST – Calculate percentile as RANK / N• PERCENTILE_DISC – Returns a discreet column value at the specified percentile• PERCENTILE_CONT – Returns a value based on the scale of column values at the specified percentile
  45. 45. More New T-SQL Functions• Logical • Date/Time – CHOOSE – DATEFROMPARTS – IIF – TIMEFROMPARTS• String – DATETIME2FROMPARTS – CONCAT – DATETIMEOFFSETFROMPARTS – FORMAT – DATETIMEFROMPARTS• Conversion – SMALLDATETIMEFROMPARTS – TRY_CONVERT – EOMONTH – PARSE • Math – TRY_PARSE – LOG (changed)
  46. 46. New SQL Server 2012T-SQL Functions
  47. 47. The THROW Statement• SQL Server 2005 added TRY/CATCH – Borrowed from .NET’s try/catch model – Vast improvement over repeatedly testing @@ERROR – Still used RAISERROR for generating errors• SQL Server 2012 adds THROW – Recommended alternative way to generate your own errors – Does not entirely replace RAISERROR• Two usages for THROW – With error code, description, and state parameters (like RAISERROR) – Inside a CATCH block with no parameters (re-throw)
  48. 48. THROW vs. RAISERRORTHROW RAISERRORCan only generate user exceptions Can generate user (>= 50000) and(unless re-throwing in CATCH block) system (< 50000) exceptionsSupplies ad-hoc text; doesn’t utilize Requires user messages defined insys.messages sys.messages (except for code 50000)Doesn’t support token substitutions Supports token substitutionsAlways uses severity level 16 (unless Can set any severity levelre-throwing in a CATCH block)Can re-throw original exception caught Always generates a new exception; thein the TRY block original exception is lost to the clientError messages are buffered, and don’t Supports WITH NOWAIT to immediateappear in real-time flush buffered output on error
  49. 49. THROW
  50. 50. Server-Side Paging• New result paging keywords • Append to ORDER BY clause • Limits the number of rows returned• OFFSET @start ROWS • The first result row to return (zero-based)• FETCH NEXT @count ROWS – The number of rows to return
  51. 51. Server-Side Paging
  52. 52. Sequences• Sequential Number Generator – As found in Oracle and DB2 – Alternative to using IDENTITY for assigning new primary keys• Advantages over IDENTITY – SET IDENTITY INSERT ON/OFF not needed for inserts – Can obtain next sequence value without performing an insert• Create a Sequence Object CREATE SEQUENCE MySequence START WITH 1 INCREMENT 1 MINVALUE 1 NO MAXVALUE• Retrieve Sequence Values INSERT INTO MyTable(Id, ...) VALUES(NEXT VALUE FOR MySequence, ...)
  53. 53. Sequences
  54. 54. Metadata Discovery• New system stored procedures and data management views• sys.sp_describe_first_result_set – Analyzes a T-SQL statement and returns information describing the schema of the statement’s result set• sys.dm_exec_describe_first_result_set – Similar, but implemented as a table-valued function to support filtering• sys.dm_exec_describe_first_result_set_for_object – Similar, but accepts an OBJECT_ID of a T-SQL object in the database to be analyzed, rather than a T-SQL statement• sys.sp_describe_undeclared_parameters – Analyzes a T-SQL statement and returns information describing the parameter(s) required by the statement
  55. 55. Metadata Discovery
  56. 56. Contained Databases• Databases are not entirely self-contained – They have external instance-level dependencies – Logins, collations, tempdb, linked servers, endpoints, etc.• SQL Server 2012 provides partial containment – Makes databases more portable – Enables (but does not enforce) containment• Can store logins (with passwords) in the database – Users authenticate directly at the database level• sys.dm_db_contained_entities – Discovers threats to containment
  57. 57. Contained Databases

  85. 85. EXCEL BI
  86. 86. PivotStuff• PivotTable, and linked charts (sometimes referred to as PivotCharts) work extremely well with OLAP cubes• How to create a PivotTable: – Ribbon’s Data tab (From Other Sources button/From Analysis Services option or Existing Connections button) – Insert tab (PivotTable “split button”)• How to insert a chart – PivotChart button on PivotTable Tools/Options tab – Several others
  87. 87. PivotCharts andPivotTables
  88. 88. Formula Language CUBE Functions• CUBEMEMBER and CUBEVALUE – Also CUBEKPIMEMBER, CUBEMEMBERPROPERTY, CUBERANKEDMEMBER, CUBESET and CUBESETCOUNT• IntelliSense style support – In a cell, type “=CU” and all CUBE formulas will display – Select one with arrow keys and hit Tab – When prompted for connection, type " and view pop-up list – Other pop-ups activate on " or "."

  90. 90. CUBExxx Formulas
  91. 91. POWERPIVOT AND EXCELSERVICES
  92. 92. Self-Service BI with PowerPivot• Excel + Analysis Services + SharePoint• Enables the working in Excel but mitigates the “spreadmart” pitfalls: – Use Analysis Services (AS) as a hidden engine Instead of no engine – Share via SharePoint, accessible by all AS clients Instead of “deploying” via email – Formal data refresh on server So data doesn’t get stale, and users don’t have to make effort at updating – Allow IT to monitor So it’s not all rogue – Provide path to more rigorous implementations Can be upsized to Analysis Services
  93. 93. Column-Oriented Stores• Imagine, instead of: Employee ID Age Income 1 43 90000 2 38 100000 3 35 100000• You have: Employee ID 1 2 3 Age 43 38 35 Income 90000 100000 100000• Perf: values you wish to aggregate are adjacent• Efficiency: great compression from identical or nearly- identical values in proximity• Fast aggregation and high compression means huge volumes of data can be stored and processed, in RAM
  94. 94. Data Import• Relational databases – SQL Server (including SQL Azure!), Access – Oracle, DB2, Sybase, Informix – Teradata – “Others” (OLE DB, including OLE DB provider for ODBC)• OData feeds, incl. R2/2012 Reporting Services, Azure DataMarket, WCF Data Services (Astoria), SharePoint 2010 lists, Visual Studio LightSwitch• Excel via clipboard, linked tables• Filter, preview, friendly names for tables/columns
  95. 95. Calculated Columns and DAX• Formula-based columns may be created• Formula syntax is called DAX (Data Analysis eXpressions). – Not to be confused with MDX or DMX. Or DACs.• DAX expressions are similar to Excel formulas – Work with tables and columns; similar to, but distinct from, worksheets and their columns (and rows)• =FUNC(table name[column name])• =FUNCX(table name, <filter expression>)• FILTER(Resellers,[ProductLine] = "Mountain")• RELATED(Products[EnglishProductName])• DAX expressions can be heavily nested
  96. 96. Import data from almost anywherePowerPivot Guidebook View data in Excel Calculated column entry Sort and filter DAX formula bar Relationship indicator Table tabs

  98. 98. Perspectives Default Aggregations Special Advanced ModeDiagram View Reporting properties Hierarchies Hide specific columns and tables Create relationships visually Measures KPIs
  99. 99. PowerPivot Client
  100. 100. Excel Services• A component of SharePoint Server 2007/2010; requires Enterprise CAL• Allows export of workbook, worksheet, or individual items to SharePoint report library – Works great for PivotTables and Charts! – Also for sheets with CUBExxx formulas or conditional formatting-driven “scorecards”• Content can be viewed in browser – Excel client not required – Drilldown interactivity maintained – Rendered in pure HTML and JavaScript – Parameterization supported
  101. 101. PowerPivot Server• Publish to Excel Services• Viewing and interacting• Data Refresh• Treating as SSAS cube – 2008 R2 version: URL to .xlsx as server name – 2012 version: use POWERPIVOT named instance and treat just like SSAS Db name is GUID-based; best to discover it – Use Excel, Reporting Services as clients And now Power View too…more later
  102. 102. The IT DashboardIncrease IT efficiency: Familiar Technologies for Authoring, Sharing, Security, and Compliance Customizable IT Dashboard Visualize usage with animated charts Simplify management of SSBI content using IT Operations Dashboard for SharePoint
  103. 103. PowerPivot Server
  104. 104. Analysis Services Tabular Mode• SSAS Tabular Mode is the enterprise/server implementation of PowerPivot• You must have a dedicated tabular mode SSAS instance• Tabular SSAS projects: BI Developer Studio (BIDS) gone PowerPivot – Implements equivalent tooling to PowerPivot Window – Can create an SSAS tabular database project by importing an Excel workbook with PowerPivot model• SSAS tabular models support partitions and roles
  105. 105. SSAS Tabular Project in BIDS SSAS tabular project menus and toolbar Measure grid and formula bar Reporting properties in Properties window
  106. 106. DirectQuery Mode• In DQ mode, model defines schema, but is not used for data• Queries issued directly against source• Similar to ROLAP storage for conventional cubes• Combine with xVelocity ColumnStore indexes for fast, real-time querying
  107. 107. SSAS Tabular Mode
  108. 108. POWER VIEW
  109. 109. What is Power View?• Ad hoc reporting. Really!• Analysis, data exploration• Data Visualization• In Silverlight, in the browser, in SharePoint• Feels a little like Excel BI• Is actually based on SSRS – Power View makes a special RDL file
  110. 110. Power View Data Sources• Power View works only against PowerPivot/SSAS tabular models – DirectQuery mode supported, however• For PowerPivot, click “Create Power View Report” button or option on workbook in SharePoint PowerPivot Gallery• For SSAS tabular model, create BISM data source, then click its “Create Power View Report” button or option – BISM data sources can point to PowerPivot workbooks too, if you want.
  111. 111. In the browser,Power View! in Silverlight Ribbon, like Excel Variety of visualizations and data formats Field list, like Excel Data regions pane, like Excel
  112. 112. View Modes Maximize one chart, fit report to window, put whole report in Reading Mode or Full Screen Create multiple pages (views)
  113. 113. Power View Basics
  114. 114. Constraining Your DataIn Power View• Tiles – A filtering mechanism within a visualization• Highlighting – Selection in one visualization affects the others• Slicers – Similar to Excel against PowerPivot• True Filters – Checked drop-down list; very Excel-like – Right-hand filter pane, similar to SSRS and Excel Services
  115. 115. Power View Filtering
  116. 116. Scatter/Bubble Charts• Allow for several measures• Features a “play” axis which can be manipulated through a slider or animated• Excellent way to visualize trends over time
  117. 117. Multipliers• Multiple charts within a chart, in columns, rows, or a matrix – Horizontal and vertical multipliers• Allows for visualizing 1 or 2 additional dimensions
  118. 118. Advanced Properties• Setting the representative column and image tells Power View how to summarize your data, and show stored images• Other properties tell it about key attributes, default aggregations and more• Reminder: “DirectQuery” mode tells Power View to get data from relational data source instead of columnar cache – Use with columnstore indexes to have the best of both worlds – columnstore indexes require Enterprise Edition, available in BI Edition
  119. 119. Power ViewAdvanced Features
  120. 120. Vocabulary• MOLAP: Multidimensional OLAP• UDM: Unified Dimensional Model• Cube: unit of schema in a dimensional database• xVelocity Columnstore Technology: PowerPivot/SSAS’ column store engine• VertiPaq: Old name for xVelocity• BISM: BI Semantic Model• IMBI: In-Memory BI engine• Tabular: a column store-based model – Because it uses tables, not cubes
  121. 121. xVelocity Columnstore Indexes• Implementation of xVelocity columnar technology engine for SQL Server relational databases – Code name was: “Apollo”• Use it by creating a columnstore index – CREATE COLUMNSTORE INDEX index ON table (col1, Col2, …)• Can ignore it in a SELECT, too: – OPTION (IGNORE_NONCLUSTERED_COLUMNSTORE_INDEX)• Can significantly increase performance of star join queries (i.e. aggregating queries with dimension lookups).• Must enable “batch” mode as well – look @ query plan to confirm!• Not as good as SSAS, but better than plain old GROUP BY
  122. 122. REPORTING SERVICESAND REPORT BUILDER
  123. 123. Scalable, Enterprise Reporting Platform• Author Impactful Reports • Powerful Designers • Flexible Report Layout • Rich Visualizations• Manage any Workload • Enterprise Scale Platform • Central Deployment • Strong Manageability• Deliver Personalized Reports • Interactive Reports • Rendering in the Format Users Want • Delivery to Location Users Want
  124. 124. Self-Service Report AuthoringReport Builder 3.0 Familiar Microsoft Office Interface Powerful Query Designer Powerful Wizards Flexible Layout Options w/ rich visualizations SharePoint list as data source PowerPivot as data source
  125. 125. Rich Visualizations
  126. 126. SSRS + SSAS = YES(S)• Reporting Services can query Analysis Services databases, including multidimensional cubes and tabular models, directly. PowerPivot too.• Uses MSOLAP OLE DB provider and issues MDX queries – Has its own query designer for MDX• Beware: SSRS essentially “flattens” SSAS data – Conforming multidimensional data to relational structures
  127. 127. Self-Service Reporting?• Fact: Reporting Services is powerful• Fact: the data visualizations in SSRS are some of the best in the BI stack• Fact: None of that makes SSRS report design end-user-friendly• Building SSRS reports, and especially charts, gauges, etc. from scratch is tedious• Until now, best end-user option has been to copy an existing report and tweak it. Yech!• There must be a better way…
  128. 128. Report Parts to the Rescue• Skilled SSRS designers can publish report parts – From Report Builder 3.0 or VS report projects• End users can pick them from a gallery – A task pane, in Report Builder 3.0, with search capability – Cannot select from VS report designer• What can be published?: – Tablixes (i.e. tables, matrices) – Rectangles – Images, Charts, Gauges, Maps – Parameters and Lists• All aided by new ability to share Datasets and original ability to share Data Sources
  129. 129. Easy to Publish; Easy to Select

  137. 137. Other Facts• Result of acquisition of Stratature• v1 is an ASP.NET application; UI is “different”• New in v2 (SQL Server 2012): • Now Silverlight-based; UI is still “different” • Excel add-in for data entry; creation of entities and attributes • Perform matching with DQS before loading• Includes .NET and Web Services APIs for reading/writing data and creating/editing models• Does not integrate with Analysis Services tools even though many of its features and concepts mirror those of dimension designer• Catalog kept in SQL Server database• Deployment packages can be created, shared and deployed
  138. 138. Objects in MDS• Models – Entities (like tables or SSAS dimensions) Attributes (like columns/fields or SSAS attributes) Common attributes are Name and Code Attribute Groups Used to taxonomize attributes within tabs in UI Members (like rows/records or SSAS members) Hierarchies (like SSAS hierarchies) Derived or Explicit Collections (like SSAS named sets) – Versions – Business rules – Workflows
  139. 139. Data Quality Services• Data Cleansing Tool• New to SQL Server 2012• Result of Zoomix acquisition• Uses Artificial Intelligence algorithms to detect invalid data and perform matching (for de-duplication)• Allows manual intervention, too• Can integrate with MDS and SSIS• Cleaner data = better adoption of your BI project
  140. 140. DQS Concepts• Knowledge Bases – Domains “semantic representation[s] of a type of data in a data field…[contain] a list of trusted values, invalid values, and erroneous data.” – Mapping• Data Quality Projects – Cleansing (i.e. correcting) Validate Using Reference Data Services and Azure DataMarket (or 3rd party providers) – Matching (i.e. de-duping) – Confidence – Profiling, Monitoring
  141. 141. StreamInsight• Microsoft’s Complex Event Handling (CEP) Product• Processes data streams that are fast and high- volume• Highly parallel C++ code assures low latency, high throughput• Not based on SQL Server, though that is its “ship vehicle”• Interesting collaborative potential with BizTalk and SSIS
  142. 142. StreamInsight Concepts• No UI. All interaction is programmatic.• Based on adapter architecture – Input and output adapters – Buy or build – Sensors, RFID readers, Web logs, market data streams are possible event sources• StreamInsight applications – Streams and events can be queried via LINQ from .NET – Server can run in-process, or shared
  143. 143. StreamInsight v1.2:New in SQL Server 2012• Resiliency: can take snapshots and restore to that saved state after an outage• Dev experience: LINQ enhancements – Multiple FROM clauses – Nested types• Extensibility: user-defined stream operators now supported• Admin features: server-wide and query- specific perf counters, Windows event logging• Included with Web and Standard Editions
  144. 144. Hadoop on Windows• Hadoop is the open source implementation of Google’s MapReduce distributed processing engine• MS working with Hortonworks to implement it on Windows – A full “distro” – Window Server, Windows Azure DIY, Windows Azure self- serve cluster provisioning• Also: ODBC driver for Hive – Works with SSRS, SSAS Tabular, PowerPivot and plain Excel.• Also: JavaScript console in the browser• Come to my session on Thursday!
  145. 145. PART IV BEYOND RELATIONAL
  146. 146. FILESTREAM
  147. 147. The Need To Stream• Data explosion accelerating the creation and management of unstructured binary large objects (BLOBs) – Photos – Audio – Video – Email messages – Spreadsheets – Documents – Etc.
  148. 148. BLOBs And The DatabaseTwo choices• Store them in the database• Store them outside the database, either in the file system or in a dedicated BLOB storeBLOBs in the database• varbinary(max) column• Integrated management• Transactional• Simplified programming• Bloats the structured file groups
  149. 149. BLOBs Inside The Database T-SQL CustomerId FirstName LastName Picture varbinary(max) 235 John Doe 0x3B0E95AE3B2F02292F0B… 236 Sally Smith 0xF3000EEF293039A2002C…
  150. 150. BLOBs And The DatabaseTwo choices• Store them in the database• Store them outside the database, either in the file system or in a dedicated BLOB storeBLOBs in the database BLOBs outside the database• varbinary(max) column • Path references to file system• Integrated management • Separate from the database• Transactional • Not transactional• Simplified programming • Complex programming• Bloats the structured file • Doesn’t interfere with groups performance
  151. 151. BLOBs Outside The Database T-SQL File I/O CustomerId FirstName LastName Picture varchar(max) 235 John Doe C:filesjdoe.jpg 236 Sally Smith C:filesssmith.jpg
  152. 152. BLOBs Using FILESTREAM• Transparently store varbinary(max) data in the file system – Declare column as “varbinary(max) FILESTREAM”• Integrated management – BLOBs are logically part of the database (backup, restore, etc.), but stored physically separate as a file group mapped to the file system• Simplified programming – SQL Server transparently links rows in relational tables to BLOBs in the file system – No developer effort required to maintain references between structured and unstructured data• Transactional – SQL Server integrates with the NTFS file system – Database transactions wrap NTFS transactions• Performant – File system is optimized for streaming
  153. 153. BLOBs Using FILESTREAM T-SQL CustomerId FirstName LastName Picture varbinary(max) FILESTREAM 235 John Doe 0x3B0E95AE3B2F02292F0B… 236 Sally Smith 0xF3000EEF293039A2002C…
  154. 154. Enabling the Service for FILESTREAM• Security concern of the Windows administrator• Set to one of four levels – Disabled – T-SQL only – T-SQL + file system (local only) – T-SQL + file system (remote)• Enable it either: – During setup – With SQL Server Configuration Manager – No way to script with T-SQL, but VBScript file is available on CodePlex that provides command-line alternative
  155. 155. Enabling the Instance for FILESTREAM• Security concern of the SQL Server administrator – Windows and SQL admins must agree! • Set to one of three levels – Disabled, T-SQL only, T-SQL + file system• Enable it either: – In SSMS Server Properties dialog – In T-SQL, with: EXEC sp_configure filestream_access_level, n RECONFIGURE
  156. 156. Creating a FILESTREAM Database• CREATE DATABASE PhotoLibrary ON PRIMARY (NAME = PhotoLibrary_data, FILENAME = C:DBPhotoLibrary_data.mdf), FILEGROUP FileStreamGroup1 CONTAINS FILESTREAM (NAME = PhotoLibrary_group2, FILENAME = C:DBPhotos) LOG ON (NAME = PhotoLibrary_log, FILENAME = C:DBPhotoLibrary_log.ldf)
  157. 157. Creating a FILESTREAM Database• CREATE DATABASE PhotoLibrary ON PRIMARY (NAME = PhotoLibrary_data, FILENAME = C:DBPhotoLibrary_data.mdf), FILEGROUP FileStreamGroup1 CONTAINS FILESTREAM (NAME = PhotoLibrary_group2, FILENAME = C:DBPhotos) LOG ON (NAME = PhotoLibrary_log, FILENAME = C:DBPhotoLibrary_log.ldf)
  158. 158. Creating FILESTREAM Columns• Table requires ROWGUIDCOL column – Attribute applied to a uniqueidentifier (GUID) column – Must be primary key or have unique constraint – Only one ROWGUIDCOL column is permitted per table• Define BLOB columns as “varbinary(max) FILESTREAM” – Any number of BLOB columns are permitted per table
  159. 159. Getting Started withFILESTREAM
  160. 160. Introducing SqlFileStream• It is not easy, practical, or efficient to manipulate BLOBs in T-SQL• Build a streaming client with SqlFileStream – System.Data.SqlTypes.SqlFileStream – Part of System.Data.dll in .NET 3.5 SP1 and higher – Inherits from Stream – Constructor takes logical path and transaction context – Wraps OpenSqlFilestream SQL Server native client API – Consumes no SQL Server memory during processing
  161. 161. The SqlFileStream Recipe• Begin Transaction• INSERT/SELECT row• Retrieve BLOB PathName()• Retrieve GET_FILESTREAM_TRANSACTION_CONTEXT()• Create and use SqlFileStream• Commit Transaction
  162. 162. BLOBs Using SqlFileStream T-SQL SqlFileStream CustomerId FirstName LastName Picture varbinary(max) FILESTREAM 235 John Doe 0x3B0E95AE3B2F020B… 236 Sally Smith 0xF3000EEF293039A2…
  163. 163. Using SqlFileStream
  164. 164. FILESTREAM Limitations &Considerations• Mirroring/HADR – Not supported with mirroring – Supported with HADR (SQL Server 2012 “AlwaysOn”)• Transparent Data Encryption (TDE) – Does not encrypt files• Replication – Supported with some restrictions, see BOL• Log Shipping – Fully supported – Primary and secondary servers require SQL Server 2008 or higher• Full-Text Search (FTS) – Fully supported
  165. 165. FILESTREAM Limitations &Considerations (cont.)• Database Snapshots – Not supported for FILESTREAM filegroups• Snapshot Isolation Level – Wasn’t supported in SQL Server 2008, supported in 2008 R2 and 2012• Local NTFS File System – Requires local NTFS file system – RBS (Remote BLOB Store) API makes SQL Server act as a dedicated BLOB store• Security – Requires mixed-mode (integrated) security• SQL Server Express Edition – Fully supported – Database size limit (4GB in SQL Server 2008, 10GB in 2008 R2 and 2012) does not include FILESTREAM data
  166. 166. HIERARCHYID
  167. 167. Hierarchical Data Is Not Relational• Today’s most common form of hierarchical data is XML• XML support added in SQL Server 2005 is great, if: – You want to store and retrieve an entire hierarchy at one time – The data is consumed in XML by client applications• Parent-child relationships define rigid hierarchies – Can’t support unlimited breadth and depth
  168. 168. Hierarchical Storage Scenarios• Forum and mailing list threads• Business organization charts• Content management• Product categories• File/folder management • FileTable in SQL Server 2012• Many more… – All typically iterated recursively
  169. 169. Traditional Self-Join Approach• One table – Each row is linked to its parent• Works, but has limitations – CTEs help with recursive queries – Still your job to manage updates – Manually maintain structure – Complex to reparent entire sub-trees – Difficult to query – Difficult to control precise ordering of siblings
  170. 170. Introducing hierarchyid• System CLR data type – Extremely compact variable-length format – Does not require SQL CLR to be enabled on the server• Enables a robust hierarchical structure over a self-joining table – Each row is a node with a unique hierarchyid value – Contains the path in the hierarchy to the node… down to the sibling ordinal position• Invoke methods in T-SQL – Efficiently query the hierarchy – Arbitrarily insert, modify, and delete nodes – Reparent entire sub-trees with a single update
  171. 171. hierarchyid Methods• GetAncestor• GetDescendant• GetLevel• GetReparentedValue• GetRoot• IsDescendantOf• Parse• ToString
  172. 172. Indexing hierarchyid Columns• Two types of indexes: Depth-First Index – Use one, the other, or both as your needs dictate• Depth-First – Create a primary key or unique index Breadth-First Index• Breadth-First – Create a composite index that includes a level column
  173. 173. hierarchyid
  174. 174. hierarchyid Example
  175. 175. FILETABLE
  176. 176. Introducing FileTable• Builds on FILESTREAM and hierarchyid• A “semi”-ordinary table that houses a logical file system – Fixed column schema – Each row represents a “folder” or “file” Column Name Data Type Description stream_id uniqueidentifier Unique row identifier ROWGUIDCOL file_stream varbinary(max) BLOB content (NULL if directory) FILESTREAM name nvarchar(255) Name of file or directory path_locator hierarchyid Location of file or directory within the file system hierarchy – Plus 10 storage attributes columns (e.g., is directory, created, modified, archive bit)• Windows file/directory management API support – A Windows file share exposes the FileTable – Bi-directional – changes to the table are reflected in the file share and vice versa
  177. 177. BLOBs Using FileTable hierarchyid column varbinary(max) Name Database Rows FileTable Name Server Machine Instance Name defines logical file Name FILESTREAM column FILESTREAM Share and folder paths contents holds each file’s T-SQL T-SQL SqlFileStreamstream_id name path_locator file_stream27D8D4AD-D100-39… Financials 0xFF271A3562… NULL78F603CC-0460-73… ReadMe.docx 0xFF59345688… 0x3B0E956636AE3B2F020B…207D4A96-E854-01… Budget.xlsx 0xFD0011039A… 0xF3F359000EEF293039A2…
  178. 178. FileTable Prerequisites• Prerequisites at the instance level – FILESTREAM must be enabled for the instance• Prerequisites at the database level – Enable non-transactional FILESTREAM access for the database (is still transactional internally) – Set a root directory name for all FileTables in the database (this will become a child in the Windows file share) – Use this T-SQL statement: CREATE DATABASE … WITH – or – ALTER DATABASE … SET – …followed by… FILESTREAM( NON_TRANSACTED_ACCESS=FULL|READ, DIRECTORY_NAME=DatabaseRootDirectory)
  179. 179. Creating a FileTable• Create a FileTable in T-SQL – CREATE TABLE TableName AS FileTable• FileTable has a fixed schema – You don’t (can’t) supply a column list• Creates logical directory – Logical root directory for the FileTable – Created beneath the root directory for the database – Named after the table, can override by specifying: WITH(FileTable_Directory=TableRootDirectory) – Exposes a functional Win32 file system – Does not support memory-mapped files (does not affect remote clients)
  180. 180. GEO-SPATIAL TYPES
  181. 181. SQL Server Spaces Out • Integrate location awareness into any application – Long been the domain of sophisticated GIS applications • GIS – A system for capturing, storing, analyzing, and managing data and associated attributes which are spatially referenced to the earth • Allow a user to interact with information that is relevant to locations that they care about: – Home, work, school, or vacation destinations • Two geospatial models – Planar – Geodetic
  182. 182. Spatial Data Types • Two spatial models = Two system CLR types • geometry – Planar (flat) model – Flat 2-dimensional Cartesian Coordinate system – X and Y coordinates with uniform units of measure – Use for mapping small areas • geography – Geodetic (round-earth) model – Latitude and longitude – Use for larger mapping where land mass is too big to fit on one planar projection
  183. 183. Planar Spatial Model • Two-Dimensional Surface – X and Y coordinates on an arbitrary plane • Flat Earth Projection – To work with geospatial data on a 2D surface, a projection is created to flatten the geographical objects on the spheroid – Example: Planar Model based on Mercator Projection Greenland Square KM: North - Antarctica = 13 million America - Greenland = 2 million Africa - N. America = 24 million - Africa = 30 million Antarctica
  184. 184. Geodetic Spatial Model • Accurate geographic measurements – Locations on planet surface described by latitude and longitude angles • Ellipsoidal sphere – Latitude = angle N/S of the equator – Longitude = angle E/W of the Prime Meridian
  185. 185. Spatial Data Standards • Open Geospatial Consortium (OGC) – International standards body • Microsoft belongs to the OGC – SQL Server 2008 uses the OGC’s Simple Feature Access standards • OpenGIS Simple Feature Interface Standards (SFS) – A well-defined way for applications to store and access spatial data in relational databases – Described using vector elements; such as points, lines and polygons • Three ways to import geospatial data – Well-Known Text (WKT) – Well-Known Binary (WKB) – Geographic Markup Language (GML)
  186. 186. Well-Known Text (WKT)• WKT examples: • POINT(6 10) • POINT(-111.06687 45.01188) • LINESTRING(3 4,10 50,20 25) • POLYGON((1 1,5 1,5 5,1 5,1 1),(2 2, 3 2, 3 3, 2 3,2 2)) • POLYGON(( -75.17031 39.95601, -75.16786 39.95778, -75.17921 39.96874, -75.18441 39.96512, -75.17031 39.95601)) • MULTIPOINT(3.5 5.6,4.8 10.5) • MULTILINESTRING((3 4,10 50,20 25),(-5 -8,-10 -8,-15 -4)) • GEOMETRYCOLLECTION(POINT(4 6),LINESTRING(4 6,7 10)) • CIRCULARSTRING(1 5, 6 2, 7 3)
  187. 187. Geospatial Methods • STArea • STBuffer • STCentroid • STDifference • STDimension • STDistance • STEnvelope • STGeomFromText • STIntersection • STIntersects • STPointFromText, STLineFromText, STPolyFromText • STPointFromWKB, STLineFromWKB, STPolyFromWKB • STSymDifference • STUnion • GeomFromGml • Parse • ToString • and more (about 70 total)
