Question

I have a stored procedure with the following structure:

CREATE PROCEDURE MyStoredProcedure(IN code INTEGER) BEGIN
    DECLARE EXIT handler FOR SQLEXCEPTION
    BEGIN
        ROLLBACK;
        SET autocommit = 1;
        SET TRANSACTION ISOLATION LEVEL REPEATABLE READ;
    END;

    SET autocommit = 0;
    SET TRANSACTION ISOLATION LEVEL READ COMMITTED;
        -- code here
    COMMIT;

    SET autocommit = 1;
    SET TRANSACTION ISOLATION LEVEL REPEATABLE READ;
END;

And I’m calling it via PDO using:

$dbh->prepare("CALL MyStoredProcedure(?);");

It works fine, but I need a way to dected from PHP if the stored procedure has raised an exception and it got “rollbacked” or it went through without errors. Can this be done?

Answer 1

Add an out param to the procedure and in case of error put there 0, or 1 on success
