Did you know that Domino and XPages allows for the easy access of relational data? These exciting capabilities in the Extension Library can greatly enhance the capability of your applications and allow access to information beyond Domino. Howard and Paul will discuss what you need to get started, what controls allow access to relational data, and the new @Functions available to incorporate relational data in your Server Side JavaScript programming.

8

15. System Requirements : Install OpenNTF Extension Library
• Install ExtLib for your release of Domino:
– Domino 8.5.3 - OpenNTF Extension Library for 8.5.3
(but not Update Pack 1 from IBM)
– Domino 9.0.0 - the OpenNTF Extension Library for 9.0.0
– Domino 9.0.1 - the OpenNTF Extension Library for 9.0.1
9

16. System Requirements : Install the JDBC Driver
• Install the JDBC Driver for your RDBMS:
– copy drivers to server (jvm/lib/ext directory)
– copy driver to NSF
– RECOMMENDED: create a plugin to install the JDBC driver
• From scratch - see procedure in XPages Extension Library book
• Using the XPages JDBC Driver Wrapper project from OpenNTF
• Using Wizard included in the OpenNTF Extension Library
Release 901v00_07 (release 7 or above)
10

17. Optional: Install the XPages RDBMS Enablement project
11

18. Enabling an NSF to use Relational Data
• Create a JDBC Connection file (.jdbc) in
WebContentWEB-INFjdbc folder in the .nsf
<jdbc>
<driver>org.apache.derby.jdbc.EmbeddedDriver</driver>
<url>jdbc:derby:${rcp.data}derbyBigOak;create=true</url>
<user>ND9XPG2</user>
<password>ND9XPG2</password>
</jdbc>
• Enable the com.ibm.xsp.extlib.relational.library
12

19. DB2sample.jdbc
• DB2sample.jdbc in WebContentWEB-INFjdbc
<jdbc>
<driver>com.ibm.db2.jcc.DB2Driver</driver>
<url>jdbc:db2://db2srvr.abc.com:50000/SampleDB</url>
<user>db2admin</user>
<password>password123</password>
</jdbc>

22. How do we Access the Relational Data?
• Two new types of data sources
• jdbcQuery – used for large data sets, read-only
• jdbcRowSet – used for read-write, cached data set
– use these with controls like a viewPanel, data view and repeat
• new @functions
• New REST Service
• Standard Java code that references connection
– two helper classes, JdbcUtil and DatabaseHelper
– see DBUtil in demo database for examples or page 425-428 of
the Extension Library book for details (or the source code!)
16

23. 17
New Data Sources for Relational Data

24. 18
New Data Sources - JDBCQuery
JDBCQuery
• Use for read only access
• connectionName - use the name of the .jdbc file
• Properties to specify the data to retrieve:
– sqlTable – specify a table
– sqlQuery – write a SQL query
– sqlFile – access SQL in a file (stored in WEB-INF)
• sqlTable overrides other two, sqlQuery overrides sqlFile
• calculateCount – allows pager to display correct number
of pages (set to true if using a pager)

25. 19
Properties for jdbcQuery Data Source

26. 20
Using a View Panel with Relational Data
1. Add view panel to page, choose Select Data Source
later
2. In the Data tab choose JDBC Query
3. Enter the query (sqlTable, sqlQuery, or sqlFile)
4. Choose the view column, go to All Properties and
enter the columnName (must match field on table)
5. Append/insert more columns as needed
6. Set the View Column Header
7. Optionally set other properties (like letting the user
change sort order)

27. 21
View Panel Control

28. Using Other Container Controls
• Relational Data Sources also work with:
– Repeat
– Data Table
– Data View
• Use the Var variable to access row data in the Value
property
– SSJS, EL or Custom
– Examples:
• SSJS: rowEntry.getColumnValue(“CITY");
– com.ibm.xsp.extlib.relational.jdbc.model.JdbcDataBlockAccessor
• EL: rowEntry.CITY
• Custom: #{rowVar.CUSTOMER} in #{rowVar.CITY}
22

29. SQL!!!
• Remember, three ways to specify the data set
– SQL Table
– SQL Query
SELECT * FROM CUSTOMERS WHERE REGION LIKE ‘East’
– SQL File
• SQL Query can have parameters
– “?” is replaced by the parameter in order
SELECT * FROM CUSTOMERS WHERE REGION LIKE ?
– sqlParameters specified in data source properties – value
property
• Best Practice is to use SQL Parameters
– Building a Query in code has security issues
– SQL Injection Attacks
23

30. 24
SQL Parameters

31. More on SQL
• Join two tables together
SELECT customers.customer, customers.contact, customers.address, customers.city,
customers.state, customers.region, regions.salesrep
FROM customers INNER JOIN regions
ON customers.region=regions.region
25

32. 26
New @Functions
• @JdbcGetConnection
• @JdbcExecuteQuery
• @JdbcDelete
• @JdbcInsert
• @JdbcUpdate

33. 27
@JdbcGetConnection
• Gets a connection – java.sql.Connection object
• @JdbcGetConnection(String:connectionname)
– gets a connection object, can use as first argument in
other @functions (or can specify the connection name)

34. 28
@jdbcDbColumn
• returns a column (Array) from a table
– can specify a where statement
– column(s) to order the results by
@JdbcDbColumn(String:connectionname , String:table , String:column)
@JdbcDbColumn(String:connectionname , String:table , String:column, String:where)
@JdbcDbColumn(String:connectionname , String:table , String:column, String:where,
String:orderBy)
@JdbcDbColumn(String:connectionname , String:table , String:column, String:where,
String:orderBy, Array:params)
var a = @JdbcDbColumn("derby1","regions", "REGION");

35. 29
@JdbcExecuteQuery
• @JdbcExecuteQuery - executes a SQL Query and
returns results (using the java.sql.ResultSet class)
@JdbcExecuteQuery(String:connectionname , String:sql)
@JdbcExecuteQuery(String:connectionname , String:sql, Array:params)
Loop through ResultSet – sample code:
var region = row.getColumnValue("region");
var sql = "SELECT SALESREP FROM regions WHERE REGION LIKE ?";
var res = @JdbcExecuteQuery("derby1",sql, region);
var salesep;
while (res.next()){
salesrep = salesrep + res.getString("SALESREP") + “, “ ;
}
return salesrep;

36. 30
@JdbcDelete
• Returns integer value with number of rows deleted
• Immediate Delete
@JdbcDelete(String:connectionname , String:table , String:where)
@JdbcDelete(String:connectionname , String:table , String:where , Array:params)
var sel = getComponent("delCust1").getValue();
if (!!sel){
var sqlwhere = "customer = ?";
dnum = @JdbcDelete("derby1", "customers", sqlwhere , sel);
@InfoMessage("The number of records deleted is " + dnum);
}else {
@ErrorMessage("Select a customer to delete");
}

37. 31
@JdbcInsert
• Inserts a row
• Returns integer value with number of rows inserted
@JdbcInsert(String:connectionname , String:table , values)
• values can be:
– an array of just values (same order and number as in
table)
– array of name/value pairs
– Java HashMap
– JSON object
var res = @JdbcInsert("derby1", "customers", newRow);

38. 32
@JdbcUpdate
• Update a row - @JdbcUpdate
– returns integer value with number of rows updated
@JdbcUpdate(String:connectionname , String:table , values)
@JdbcUpdate(String:connectionname , String:table , values, String:where)
@JdbcUpdate(String:connectionname , String:table , values, String:where ,
Array:params)
• values can be:
– an array of just values (same order and number as in table)
– array of name/value pairs
– Java HashMap
– JSON object
var wheresql = "customer = ?";
var vals = {contact:contactValue};
res = @JdbcUpdate("derby1", "customers", vals, wheresql , sel);
@InfoMessage("The number of records updated is " + res);

39. 33
jdbcConnectionManager control
• Manages multiple data sources
• Set transaction isolation level for
concurrent operations
– see table 12-3 in Ext. Lib book for settings
• Specify the id of the connection
manager In the data source property
called connectionManager
• Use when on the same XPage you have:
– Multiple transactions to commit at the
same time
– Multiple data sources

43. JDBC RowSet Data Source
• Used to read and write data (caches results)
1. Setup jdbcRowSet data source
2. Call newRow() method to create a new record
3. To edit a row - setup row data object using the
Object Data Source
• Call getRow() method in createObject property
• Call saveRow() method in saveObject property
4. call acceptChanges() method to commit changes to
database
