Hello ! I'm trying to write a little trigger function with variable arguments quantity (at least one, but can be 2,3,4 arguments). Theses arguments are fields name, so only varchar variable.
Since it is a dynamic query, I use the EXECUTE statement as explained on <http://www.postgresql.org/docs/8.3/interactive/plpgsql-statements.html#PLPGSQL-STATEMENTS-EXECUTING-DYN> CREATE OR REPLACE FUNCTION delete_acl_trigger() RETURNS trigger AS $delete_acl_trigger$ DECLARE BEGIN FOR i IN 0 .. TG_NARGS LOOP EXECUTE 'SELECT delete_acl(OLD.' || TG_ARGV[i] || ');'; END LOOP; RETURN OLD; END; $delete_acl_trigger$ LANGUAGE plpgsql; But, when the trigger is triggered, I receive this error message : "Query failed: ERROR: OLD used in query that is not in a rule" How can I get the value of the OLD.' || TG_ARGV[i] field ? Many thanks in advance !
