RE: SQL Proceure Questions

Alan,

It is slick.  What's interesting is that, as far as I know, SQL UDFs have 
always functioned this way.  Which makes sense, given that a UDF needs to run 
as quickly as possible as it would be called once for each row in a table with 
millions of rows.  The interesting thing is that prior to v5r3, an external UDF 
had to be a *PGM.  You couldn't call a procedure in a *SRVPGM as a UDF; even 
though IBM obviously could.
