How can I use transactions in my MySQL stored procedure?

Solution 1:

Two syntax errors:

• You need commas in between the conditions for your exit handler. Notice the syntax documentation shows commas.

• You need to terminate the END of the exit handler with a semicolon. The DECLARE statement itself (including its BEGIN...END block) is a statement like any other, and need to have a terminator.

So you need this:

DECLARE EXIT HANDLER FOR SQLEXCEPTION, SQLWARNING
BEGIN
    ROLLBACK;
END;

Solution 2:

Try like this ie, include your Declare statement inside the START TRANSACTION;. Earlier your ROLLBACK was not a part of TRANSACTION as you wrote it above the START TRANSACTION:-

BEGIN

DECLARE poid INT;

DECLARE EXIT HANDLER FOR SQLEXCEPTION, SQLWARNING

START TRANSACTION;

BEGIN
    ROLLBACK;
END

    -- ADD option 5
    INSERT INTO product_option(product_id,option_id,required) VALUES(insertedProductID,5,0);
    SET poid = (SELECT LAST_INSERT_ID());
    INSERT INTO product_option_value(product_option_id,product_id,option_id,option_value_id,quantity,subtract,price,price_prefix,points,points_prefix,weight,weight_prefix) VALUES(poid,insertedProductID,5,50,0,0,4.99,'+',0,'+',0,'+');

    -- ADD option 12
    INSERT INTO product_option(product_id,option_id,required) VALUES(insertedProductID,12,1);

    -- ADD option 13
    INSERT INTO product_option(product_id,option_id,required) VALUES(insertedProductID,13,0);

COMMIT;

END
