This document summarizes new features coming in SQLScript for SAP HANA SPS 10. Key additions include support for COMMIT/ROLLBACK in procedures, anonymous blocks, header-only procedures/functions, SQL inlining hints, and allowing multiple outputs from scalar user-defined functions to be assigned to multiple variables. The document also outlines tooling improvements like code completion and debugging in the web-based development workbench. Future plans mentioned include performance enhancements for SQLScript v3 and adding GIS support.

SQLScript – What’s New in SPS 10
Commit/Rollback
COMMIT/ROLLBACK
• Supported in procedures only, not supported for scalar or table UDFs
• COMMIT command commits the current transaction and all changes before the COMMIT
command
• ROLLBACK command rolls back the current transaction and undoes all changes since the last
COMMIT
• Transaction boundary is not tied to the procedure block, so if there are nested procedures that
contain COMMIT/ROLLBACK then all statements in the top-level procedure are affected.
• If dynamic SQL was used in the past to execute COMMIT and ROLLBACK statements, it is
recommended to replace all occurrences with the native command because they are more
secure.

SQLScript – What’s New in SPS 10
Commit/Rollback(Cont.)
COMMIT/ROLLBACK
• The first and third INSERT
statements affect the productLog
table, but not the second since it
was rolled back.
• With the first COMMIT, the first
transaction is written to
persistence, and a new transaction
is started
• By triggering ROLLBACK, all
changes in the second transaction
are reverted, and a new
transaction is started

SQLScript – What’s New in SPS 10
Anonymous Blocks
Anonymous Blocks
• Executable DML statement which
can contain imperative and
declarative statements
• No lifecycle handling(e.g.
CREATE/DROP), no catalog object
• No parameters or container specific
properties such as language, or
security mode
• Supports complete SQLScript
language

SQLScript – What’s New in SPS 10
Header Only Procedures/Functions
Header Only Procedures/Functions
• When creating a procedure, all nested procedures need to exist beforehand
• Create procedures/functions with minimum metadata first using the HEADER ONLY extension
• Inject the body of the procedure/function by using the ALTER PROCEDURE statement
CREATE PROCEDURE <proc_name> [(<parameter_clause>)] AS HEADER ONLY
ALTER PROCEDURE <proc_name> [(<parameter_clause>)]
[LANGUAGE <lang>]
[SQL SECURITY <mode>]
[DEFAULT SCHEMA <default_schema_name>]
READS SQL DATA AS
BEGIN
<procedure_body>
END;

SQLScript – What’s New in SPS 10
SQL Inlining Hints
SQL Inlining Hints
• Used to explicitly enforce or block the
inlining of SQL Statements within
SQLScript
• Depending on the scenario, execution
performance could be improved
Example: Block Statement-Inlining
CREATE PROCEDURE procNoInline ( OUT tab2 tt_tab )
LANGUAGE SQLSCRIPT READS SQL DATA AS
BEGIN
tab = SELECT * FROM T WITH HINT (NO_INLINE);
--> Statement will not be inlined into tab2
tab2 = SELECT * from :tab;
END;
Example : Enforce Statement-Inlining
CREATE PROCEDURE procInner (IN tab1 tt_tab, OUT tab2 tt_tab )
LANGUAGE SQLSCRIPT READS SQL DATA AS
BEGIN
tab2 = SELECT I FROM :tab1 WITH HINT (INLINE);
--> Statement will be inlined into the statement of
--> variable table2 of procedure procCaller
END;
CREATE PROCEDURE procCaller (IN table1 tt_tab,
OUT table2 tt_tab)
LANGUAGE SQLSCRIPT READS SQL DATA AS
BEGIN
call procInner (:table1,outTable);
table2 = select I from :outTable;
END;

SQLScript – What’s New in SPS 10
Multiple Scalar Variable Assignments
Multiple Scalar Variable Assignments
• Prior to SPS 10, multiple parameter
assignment for scalar UDFs was not
supported. You were forced to do the
assignment via SELECT statement
SPS 10 assign multiple outputs of Scalar UDF to multiple scalar variables
CREATE PROCEDURE proc(IN a int, IN b int,
OUT x int, OUT y int)
LANGUAGE SQLSCRIPT READS SQL DATA AS
begin
(x,y) = inner_func1(a,b);
end;
It is also possible to only assign a single output
CREATE PROCEDURE proc(IN a int, IN b int,
OUT x int, OUT y int)
LANGUAGE SQLSCRIPT READS SQL DATA AS
begin
x = inner_func1(a,b).x;
y = inner_func1(a,b).y;
end;
SPS 09 consuming multiple result via SELECT statement
CREATE PROCEDURE proc(IN a int, IN b int,
OUT x int, OUT y int)
LANGUAGE SQLSCRIPT READS SQL DATA AS
begin
select inner_func1(a,b).x, inner_func1(a,b).y
into x,y from dummy;
end;

SQLScript – What’s New in SPS 10
Table Types for Table Variable Declarations
Table Type for Table Variable Declarations
• Reference a table type in DECLARE statement
• Must contain runtime object name including schema
CREATE PROCEDURE test_table_type( )
LANGUAGE SQLSCRIPT READS SQL DATA AS
BEGIN
declare lt_tab "SAP_HANA_EPM_NEXT"."sap.hana.democontent.epmNext.data::MD.Products";
lt_tab = select * from "SAP_HANA_EPM_NEXT"."sap.hana.democontent.epmNext.data::MD.Products";
select * from :lt_tab;
END;
