Hi Wes -

I'm converting a RPG program to SQLRPG due to OPNQRY file performance. In
the program the same file is opened three times. The first two file are
logical and the third is a join file. Based on the PF, there is a DS (DS1).
I tried to create an extrenally defined DS(DS2) based on the logical file
but kept getting an error:

 * QRG4072 Severity:  30   Number:  140
           Message . . . . :   Subfield-Name specified already defined as
             Subfield-Name. Specification line ignored.


then I tried to create the second DS based on the first, but I'm still
getting the same error. My question is: is it possible to have a one DS as a
subset of another DS?


The same field name cannot appear in more than one data structure.

In RPG IV you could use prefixes or qualified data structures though. Idon't know how well they would work with SQL though, since I don't use SQLin RPG.
