Thanks, Birgitta, this works well.
We have a shop standard that each program will use a program-specific view so that it only brings in the columns the program needs. In this particular case, however, the program needs to join its program-specific view with a work file that has previously been created in QTEMP.
I had to make one change, in that the second view in the join can contain nulls, so I used:
Exec SQL Fetch Next From YourCursor into :DDLWRK1, :DDLWRK2 :INDXX;
I assume that if both views were null-capable then the format would be:
Exec SQL Fetch Next From YourCursor into :DDLWRK1 :INDYY, :DDLWRK2 :INDXX;
Many thanks for your help.

Even though it is much better to only select the columns you really need, if
you want to join 2 tables and fetch the result of both records, just list
the data structures:
Exec SQL Fetch Next From YourCursor into :DDLWRK1, :DDLWRK2

Betreff: Fetching joined views
I have a SELECT in an RPG program that joins an existing view MYVIEW (in
QTEMP) and a table MYTABLE. I tried to declare the combined input buffer
like this:
d ddLWRK1 e ds ExtName(MYVIEW)
d ddLWRK2 e ds ExtName(MYTABLE)
d ddLWRK ds Qualified
d ddLWRKDS1 LikeDS(ddLWRK1)
d ddLWRKDS2 LikeDS(ddLWRK2)
and my fetch would be:
exec sql
FETCH SqlCsr Into :ddLWRK;
But I get an "SQL0312: Position 40 Variable DDLWRK not defined or not
usable" error
Is it even possible to do what I'm attempting - i.e. avoiding having to
define the input fields manually?
We're currently on bare-bones release 7.1.
Thanks,
