Description
The SQLScript procedure of the AMDP method INCREASE_PRICE of the AMDP class CL_DEMO_AMDP_CALL_AMDP calls a further AMDP procedure implemented in the private AMDP method INCREASE_PRICE_AMDP in the same class:
FOR HDB LANGUAGE SQLSCRIPT
USING cl_demo_amdp_call_amdp=>increase_price_amdp.
call "CL_DEMO_AMDP_CALL_AMDP=>INCREASE_PRICE_AMDP"(
CLNT => :CLNT, INCPRICE => :INCPRICE );
ENDMETHOD.
FOR HDB LANGUAGE SQLSCRIPT
USING sflight.
update sflight set price = price + incprice
where mandt = clnt;
ENDMETHOD.
The called database procedure must be specified after the addition USING
of the statement METHOD
. Compare the
example for calling a further database procedure not managed using AMDP.
