Thank you Birgitta. Dave's and your solution was just the thing for my
problem. For some reason I thought that if you fetched to a datastructure,
that you could only use one.

Why not defining 2 independent data structures and specifying them both in
the FETCH-Statement?

DCL-DS F1 LikeDS(IMIP_T);
DCL-DS F2 LikeDS(IMIP_T);
...
Exec SQL Fetch C3 into :F1, :F2;

Mit freundlichen Grüßen / Best regards

Subject: joining 2 files in datastructure assignment

I'm trying to figure out a better way to define a datastructure for a
cursor
fetch when I have two files joined in an SQL. See the next as an example.
I'd like to define the datastructure as two external structures combined,
but the compiler doesn't like it much when I try. What i'm doing now is
specifying each field individually (77 fields in each file), so not only
is
that a lot of fields to define, but I'm currently off somewhere (not in
this
example), so I'm having to slowly find where I made a mistake, and I'd
rather let the compiler do the work.




dcl-ds IPIM_t extname('IPIM') qualified template end-ds;

// I know this doesn't work, but its an example of what I'm
trying to specify
dcl-ds C1_t qualified template;
F1 likeds(IPIM_t);
F2 likeds(IPIM_t);
end-ds;

dcl-ds C1 likeds(C1_t) INZ;

// Parts in both systems with some kind of difference
exec sql declare C3 cursor for
select t2.*,IPIMX.*
from (select *
from QTEMP/IPIMP
except select *
from QTEMP/IPIMX) t2
join QTEMP/IPIMX
on IPIMX.PARTNUM=t2.PARTNUM;

exec sql open C3;
exec sql fetch C3 into :C3;
