  ABAP Statement

EXEC SQL - EXECUTE
• EXECUTE PROCEDURE EXEC SQL
• IN EXEC SQL
• OUT EXEC SQL
• INOUT EXEC SQL


ABAP Syntax EXEC SQL.
EXECUTE PROCEDURE proc ( IN p_in1 IN p_in2 ...,
OUT p_out1 OUT p_out2 ...,
INOUT p_inout1 INOUT p_inout2 ... )
ENDEXEC.

What does it do? In database systems, procedures can be defined as stored procedures. Since the syntax for calling such procedures and the associated pass by parameter can vary widely for various database systems, a uniform command exists in statically embedded Native SQL.

The statement EXECUTE PROCEDURE calls a procedure proc stored in the database. For all formal parameters of the procedure, the actual parameters must be specified, separated by commas. IN, OUT, or INOUT must be specified before every actual parameter, to indicate whether the parameter is an input, output, or input/output parameter. For the actual parameters, literals or host variables denoted by a colon (:) can be used, which can also be internal tables in this case. If they are internal tables, these must be standard tables without secondary table keys.



Latest notes:On the SAP HANA database, the stored procedures are database procedures written in SQLScript. The more powerful statement CALL DATABASE PROCEDURE is used to call these procedures.



Example ABAP Coding
Definition of a procedure incprice using database-specific SQL statements (Oracle) and calling the procedure with the SAP-specific Native SQL statement EXECUTE PROCEDURE. The execution of the program section raises the price of every flight for the client '000' in the table SFLIGHT by a specific amount. PARAMETERS incprice TYPE sflight-price.

EXEC SQL.
CREATE OR REPLACE PROCEDURE increase_price (x IN NUMBER) IS
BEGIN
UPDATE sflight SET price = price + x
WHERE mandt = '000';
END;
ENDEXEC.

EXEC SQL.
EXECUTE PROCEDURE increase_price ( IN :incprice )
ENDEXEC.



Example ABAP Coding
This example defines a selfunc procedure using database-specific SQL statements (Informix). It also calls the procedure using the SAP-specific Native SQL statement EXECUTE PROCEDURE in a LOOP loop by means of a selection table, and deletes the procedure using an SQL statement. In the case shown here, the procedure is a function whose return value output in EXECUTE PROCEDURE is passed to the host variable name. DATA scarr_carrid TYPE scarr-carrid.
SELECT-OPTIONS s_carrid FOR scarr_carrid NO INTERVALS.
DATA s_carrid_wa LIKE LINE OF s_carrid.

DATA name TYPE c LENGTH 20.

TRY.
EXEC SQL.
CREATE FUNCTION selfunc( input CHAR(3) )
RETURNING char(20);
DEFINE output char(20);
SELECT carrname
INTO output
FROM scarr
WHERE mandt = '000' AND
carrid = input;
RETURN output;
END FUNCTION;
ENDEXEC.
LOOP AT s_carrid INTO s_carrid_wa
WHERE sign = 'I' AND option = 'EQ'.
TRY.
EXEC SQL.
EXECUTE PROCEDURE selfunc( IN :s_carrid_wa-low,
OUT :name )
ENDEXEC.
cl_demo_output=>write( |{ s_carrid_wa-low } {
name }| ).
CATCH cx_sy_native_sql_error.
cl_demo_output=>write_text( `Error in procedure execution` ).
ENDTRY.
ENDLOOP.
EXEC SQL.
DROP FUNCTION selfunc;
ENDEXEC.
CATCH cx_sy_native_sql_error.
cl_demo_output=>write_text( `Error in procedure handling` ).
ENDTRY.
cl_demo_output=>display( ).
