Currently what I basically have is this:
CREATE PROCEDURE 'Teste'(
IN '@valorX' INT,
IN '@valorY' INT
)
NOT DETERMINISTIC CONTAINS SQL SQL SECURITY DEFINER
INSERT INTO tabelaX(colunaX) VALUES (@valorX)
INSERT INTO tabelaY(colunaY) VALUES (@valorY)
Note: The two tables do not have links to each other.
