unconnected stored procedure transformation in informatica


By on 02:08:00





Assume we need two output parameters AN_SAL and Half_yearly_sal. INPUT parameter is one here SAL.



SQL> CREATE OR REPLACE PROCEDURE CALC_AN_HLF_YR_SAL(P_SAL in EMP.SAL%TYPE,P_AN_SAL OUT NUMBER,P_HLF_SAL OUT NUMBER) is

BEGIN

P_AN_SAL:=P_SAL*12;

P_HLF_SAL:=P_SAL*6;

END;



DEFINE A MAPPING M_SP_UNC. Drag Source,Target EMP_SP_UNC and create two transformations: Expression T_EXP_SP_UNC and Stored procedure T_SP_UNC.

Project the required ports from Source Qualifier to the Expression Transformation.

Edit the Expression Transformation and add two new port AN_SAL (change datatype, precision and scale), HLF_YR_SAL .

Also add one port hlf_sal which is a variable port.

Go to Function tab of the Expression Editor, go to Stored procedures folder and Dbl click on T_SP_UNC

Assign the parameters SAL (IN), PROC_RESULT (Informatica Global Variable) and hlf_sal (local variable).

:SP.SP_UNC(SAL,PROC_RESULT,hlf_sal)




Note: PROC_RESULT captures the first output parameter. 

If we use some local variable instead of PROC_RESULT, it gives an error.

Example if I use the formula

:SP.SP_UNC(SAL,hlf_sal,hlf_sal)

In HLF_YR_SAL formula, assign the variable hlf_sal. (Confirm)

Project required ports from Expression Transformation to TGT.

NOTE: Unconnected Stored Procedure Transformation is used to project more than one output parameter.
