Обсуждение: Record Types Structure in PL/pgSQL
Hi there.
Is there any way of determining the actual structure of a record variable? E. g. I've written a small script to do some calculations over some fields with a dinamically generated query. It looks like this:
create function foo(text) returns void as
$$
declare
a_record record;
my_query alias for $1;
begin
for a_record in execute my_query loop
-- Do some calculations
end loop;
return;
end;
$$
language plpgsql;
The question is: how could I possibly get the field names and other information about the record a_record? I appreciate any suggestions or tips about this.
Best regards.

Hello it isn't possible in plpgsql. Try other plperl or plpython Regards Pavel Stehule 2007/6/6, Diego Sanchez <dsanchez@roldansia.com.co>: > > Hi there. > > Is there any way of determining the actual structure of a record variable? > E. g.
