Hi,
I couldn't find the logical error in my function, so I was wondering if there
could be a bug. The function is created, but when I try to use it I get the
following error message:
NOTICE: Error occurred while executing PL/pgSQL function apaga_constraint
NOTICE: line 20 at for over select rows
ERROR: parser: parse error at or near "$1"
The function code follows:
CREATE OR REPLACE FUNCTION apaga_constraint (varchar)
RETURNS INTEGER AS '
DECLARE
nome ALIAS FOR $1;
registro RECORD;
qtd INTEGER;
constr_oid INTEGER;
BEGIN
qtd := 0;
SELECT oid
INTO constr_oid
FROM pg_class
WHERE relname::TEXT = nome;
-- Caso nao seja chave primaria
IF NOT FOUND THEN
RAISE NOTICE ''Nao eh pk: %'', nome;
FOR registro IN
SELECT t.tgrelid, COUNT(t.tgname) AS qtd
FROM pg_trigger t
WHERE t.tgconstrname::TEXT = nome
GROUP BY t.tgrelid
LOOP
RAISE NOTICE ''Class: % Triggers: %'', registro.tgrelid, registro.qtd;
END LOOP;
-- Caso seja chave primaria
ELSE
RAISE NOTICE ''Oid: %'', constr_oid;
END IF;
RETURN qtd;
END;
' LANGUAGE 'plpgsql';
SELECT apaga_constraint('fk_teste2_teste');
My apologies for this poor english,
Alvaro
