AW: SQL Select Statement in a Stored Procedure Question

Hi,

a stored procedure has no return value with the exception of result sets.
It's not possible to receive result sets in a Select-Statement.

If you want to retrieve a return value or a table in a SQL-Select-Statement
as you specified, you either have to create a User Defined Function (UDF) or
a User Defined Table Function (UDTF)

Example:
Create Function MySchema/MyUDF(ParmItemNo Integer)          
       Returns VarChar(50)                                     
       Language SQL                                         
       Deterministic                                        
       Reads    SQL DATA                                    
       Returns NULL on NULL Input                           
       DisAllow PARALLEL                                    
       Return (Select ItemDesc from MyTable where ItemNo = ParmItemNo)
;

An UDF can be used as follows:
select itemnum as ItemNum, MyUDF(itemNum) as ItemDescription
from db2table

An UDTF can be used as follows:
Select Fld1, Fld2 .... FldN
>From table(MyUDTF(Parm1, Parm2, ... ParmN)) as MyTable

Betreff: SQL Select Statement in a Stored Procedure Question

All right....I know I should have the web developer join the list & ask this
question, but here goes again......

We want to do a select statement encapsulated in a stored procedure which
returns a result set to a calling program.  Nested inside the stored proc we
want to call another stored proc within a select statement.
 
Such as......
 
select itemnum as ItemNum
(call storedprocedure(itemnum) as ItemDescription
from db2table

Is there a way to do this?

Any help would be greatly appreciated.
