Good afternoon to all of you!
I need your help. I create a master detail form. I created also a post quey trigger, inside I wrote the code below.
A cursor looks to another table and returns to the form some values i need!
declare
cursor C1 is
select apofaa, startdate, enddate, transport
from trapofdet
where trapofdet.apofcode = :trapof.apofcode;
begin
open C1;
loop
fetch C1
into :TRAPODOSI_NEW_NEW.APOFAA,
:TRAPODOSI_NEW_NEW.STARTDATE,
:TRAPODOSI_NEW_NEW.ENDDATE,
:TRAPODOSI_NEW_NEW.TRANSPORT;
exit when C1%notfound;
next_record;
end loop;
close C1;
first_record;
null;
end;
How to solve the
a. frm-40737, illegal restricted procedure go block in post-query trigger
b. It seems tha returns all the records but it appears only the last one.
Please can anybody help with these?
Thanks in advance!
Christos

You've misunderstood when post-query fires. It fires once for each record returned by a query. Not once for the block/query. Hence a cursor loop is not needed. Consequently the next_record/first_record aren't needed either - which is just as well since they're not allowed in post-query.
Consequently LF's code is all that is needed. Though if the that query does return multiple records you're going to need to change the where clause to something more restrictive - ie get the data for the current record in the block only.
