RE: Help with SQL Procedure

[Greg Wilburn <gwilburn@xxxxxxxxxxxxxxxxxxxxxxx>]

Birgitta,

This is a function... I am using it in an SQL Select statement within an SQL view - selecting it like field.
SELECT
                        DFT_WHS,
                        CLT.COM_NBR,
                        CLT.COM_NAME,
                        WHS_NBR,
                        RF.PICKER,
                        RF.STD_LPH,
                        RF.RDS_LPH,
                        ODORD# AS ORD_NBR,
                        ODREL# AS REL_NBR,
                        COUNT(ODCTT#) AS LINES,
                        PIK_DATE,
                        PIK_TIME,
                        ASTHHOBJ.TBF_SHIPBYDATE(PIK_DATE, PIK_TIME,PTY_CODE),
                        PTY_CODE,
                        PTY_DESC


                FROM...

I created this function years ago (maybe 8 or 9).
It references an RPG procedure (TBF_ShipbyDate) in a SRVPGM called TBFUTILR4
This procedure calls another procedure inside the same SRVPGM which uses SQL

My problem is that I cannot find any reference to it on our system - even though it is still functioning.

I hesitate to re-create it for fear of breaking it, and the views that use it.

Is there a way to "recover" the SQL statement that created the function?

Thx,
Greg

You have to register your RPG-Function as an external Function.
Something like this:

CREATE OR REPLACE FUNCTION ASTHHOBJ.TBF_SHIPBYDATE (
        PARDATE  DATE ,
        PARTIME  TIME,
               PARCODE VARCHAR(3))
        RETURNS DATE
        LANGUAGE RPGLE
        SPECIFIC YOURNAME
        EXTERNAL NAME 'YOURLIB/YOURSRVPGM(YOURRPGFUNCTION)' ;

BTW in SQL there is a difference between Function and Procedure.
A (stored) procedure can have input and output parameters and return a result set, but must be called with the SQL CALL Statement.
A (user defined) function has a return value and only input parameters. It can be called within a SQL Select-Statement or INSERT, UPDATE, DELETE ...
like any scalar function.

Subject: Help with SQL Procedure

I'm losing my mind...



I have an SQL view that references a procedure (function) in one of my RPG service programs.  I'm fairly certain at some point I had to create an SQL procedure/function to access the RPG function from within a view.  But I cannot find anything using the Database Management tool in ACS.



Shouldn't I be able to find an SQL Procedure or Function in the same library?



One of the columns selected in my view is ASTHHOBJ.TBF_SHIPBYDATE(PIK_DATE, PIK_TIME,PTY_CODE),



This returns a Date based on the parameters passed in.

Even if I click on "All Database Objects" in this library, I do not see anything named "TBF_SHIPBYDATE".





My user profile has *ALLOBJ authority (I would have created the objects
anyway)

I can see the procedure referenced when I regenerate the SQL source from the view object.

I tried RCLDBXREF OPTION(*FIX) for that library (as Charles suggested in the RPG group).



What am I missing?



TIA,

Greg
