Re: joining 2 files in datastructure assignment

You define a DS as C1 but Fetch it in C3

Kind regards,

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;
