Hi,
the function bellow is created successfully, but executing it forces the
following error message:
WARNING: Error occurred while executing PL/pgSQL function
drop_table_if_exists
WARNING: line 5 at select into variables
ERROR: parser: parse error at or near "$1" at character 34
CREATE OR REPLACE FUNCTION drop_table_if_exists(TEXT) RETURNS BOOLEAN AS '
DECLARE
rec RECORD;
BEGIN
SELECT INTO rec off_mitarbeiter_id FROM $1;
IF FOUND THEN
EXECUTE ''DROP TABLE'' || '' '' || $1;
RETURN true;
END IF;
RETURN false;
END;'
LANGUAGE 'plpgsql';
select drop_table_if_exists('off_jahres_abr_2003');
If I hardcode the table name istead of using $1, everything works fine.
Please help.
Thanx Erwin
