Hi list,

I'm just added to the list and I'm not sure whether the following is a
FAQ or not possible. Anyway, here it goes:
Is there a way to execute a query stored in a string?

I mean, something like:

function test(text) as returns opaque as '
declarev_weekday alias for $1;s_qry text;rec record;
begins_qry = ''select field1,field2, '' || v_weekday || '' from t_diary'';for rec in exec_sql(s_qry)
--               ^ this is what I'm looking for...
--        [do what is needed]loopend loop;
end;
' language 'plpgsql';

Thanks in advance,
Virgilio
