This document summarizes new features in SAP HANA SPS 11. It introduces a new CASE JOIN that allows extension of views by custom fields from different tables. It describes new SQL functions for grouping, conversion, and checking for empty tables. It outlines enhanced monitoring and supportability views. A new PROJECTION VIEW type is introduced that supports triggers and uses primary keys to link to underlying tables. For SQLScript, new features include ALTER support for procedures/functions, TRUNCATE, filter pushdown for table UDFs, system variables for object names, default values, empty parameters, checking for empty tables, index-based cell access, spatial data type/functions, and injection prevention procedures.

CASE JOIN
New SQL Functions

Projection Views

4. CASE JOIN

5. © 2015 SAP SE or an SAP affiliate company. All rights reserved. 5Public
New JOIN Type for “Extension by Custom Fields” and Views
ext1
br2
BSEG
VBSEGD
br1
ext2
Union All View
BSEG br1 br2VBSEGD
ext1BSEG br1
br2VBSEGD
Final View
New: Case Join Select * from V left outer many to one case join
when br = 'br1' then
return ext1 as ext from BSEG on V.key = BSEG.key
when br = 'br2' then
return ext2 as ext from VBSEGD on V.key = VBSEGD.key
end;
pruning out unnecessary self-joins,
re-define only the top-most view
ext2

6. SQL Functions

7. © 2015 SAP SE or an SAP affiliate company. All rights reserved. 7Public
SQL Functions
group_contains(), group_why_found(), group_score()
• Query searches for objects that match a pattern over multi-records and multi-columns
to_snumc(), snumc_to_int(), snumc_to_bigint(), snumc_to_decimal()
• current to_alphanum() function converts integer-values in a character-format, which is specifically used to
integrate “external” integer data directly into the BW-Reporting as characteristics
• non-SQL standard behavior (cannot be pushed down to other DBMS for SDA, no support for DT)
• No support for negative numbers
• New functions preserves order in target string and can handle negative numbers

8. Supportability

9. © 2015 SAP SE or an SAP affiliate company. All rights reserved. 9Public
Monitoring Views
M_EXECUTED_STATEMENTS (New)
 Historize executed DDL operations
 Similar fields like m_expensive_statements, but includes error_code and error_text
 Enabled by default
M_EXPENSIVE_STATEMENTS (ENHANCED); downported to rev102
 Column “workload_class_name” added
 Displays mapped workload class of a statement (if workload class is defined)
M_CONNECTIONS (ENHANCED); downported to rev102
 Column “close_reason” added, e.g. 'due to idle connection timeout’
 empty for normal cases

10. Projection View

11. © 2015 SAP SE or an SAP affiliate company. All rights reserved. 11Public
Projection View
New Viewtype
 New:
– Can be used in HANA column views
– Insert/Update/Delete triggers on projection view are supported
 Syntax:
– CREATE PROJECTION VIEW < view_name> [(<column_name_list>)] AS SELECT <field_list> FROM [<schema>.]<table_name>
– DROP VIEW <view_name>
 Pre-requisite
– Projection view must include all primary keys of the underlying table

SQLScript – What’s New in SPS 11
Filter Pushdown for Table User Defined Functions
• Filter by column of table UDF via
WHERE clause
• Filter is pushed down, and result
set is not materialized before the
filtering
• Prior to SPS11, filter pushdown
was blocked for table UDF which
contained imperative logic
constructs.

System Variables for Object Name and Schema
• Use
::CURRENT_OJECT_SCHEMA
to return the schema name of
the current procedure or
function
• Use
::CURRENT_OBJECT_NAME
to return the name of the
current procedure or function

SQLScript – What’s New in SPS 11
Default Values for Table Variables & Parameters
• Used to initialize table
variables and parameters
with tabular data
• Reference a persisted table
which contains the data
• DEFAULT can also be used
within the DECLARE
statement

SQLScript – What’s New in SPS 11
Default Empty IN/OUT Table Parameters
• Used to initialize IN/OUT
table parameters
• If DEFAULT EMPTY is not
used and no assignment to
the output parameter exists
in the body, an error occurs.

variable/parameter or table contains
any rows
SPS10 SPS11

Index-based Cell Access for Table Variables
• Used to directly access any cell
(read/write) within a table
variable or parameter
• <table>.<column>[<index>]
notation

SQLScript – What’s New in SPS 11
Spatial Support
• SQLScript supports the
spatial data type
ST_GEOMETRY and SQL
spatial functions to access
and manipulate the spatial
data.
• SQLScript also supports the
objective style function
calls, which is needed for
some SQL spatial functions.

SQLScript – What’s New in SPS 11
Injection Prevention Built-In Procedure
• There is a danger of SQL injection attack if dynamic SQL statements are used, where the parts
of it are derived from untrusted input (e.g. user interface).
• ESCAPE_SINGLE_QUOTES(string_var)
 used for variables containing a SQL string literal
• ESCAPE_DOUBLE_QUOTES(string_var)
 used for variables containing a delimited SQL identifier
• IS_SQL_INJECTION_SAFE(string_var[, num_tokens])
 used to check that a variable contains safe simple SQL identifiers (up to num_tokens, default is 1)
