seems MySQL stored procedures can do transactions. Yet when I declare my stored function create function test( a int ) returns int MODIFIES SQL DATA BEGIN START TRANSACTION ; update t set col='some value' where id=a ; COMMIT ; return 0 ; END // I get Error Code: 1422. Explicit or implicit commit is not allowed in stored function or trigger. mysql stored-procedures stored-functions share|improve this question asked Jun 6 '13 at 18:49 bobobobo 27.4k32184243 add a comment| 1 Answer 1 active oldest votes up vote 8 down vote accepted Actually you are not allowed transactions inside stored functions. You are allowed transactions inside stored procedures only. create procedure test( a int ) MODIFIES SQL DATA BEGIN START TRANSACTION ; update t set col='some value' where id=a ; COMMIT ; END // To return values from the SP, use output parameters or use the result set from the last select statement in the SP. share|improve this answer answered Jun 6 '13 at 18:49 bobobobo 27.4k32184243 5 Also worth noting is that if you call the procedure from within a trigger, you will still be rewarded with an 'Explicit or implicit commit is not allowed in stored function or trigger' error. Frustrating. –aroth Jan 24 '14 at 6:27 hey, this is a bit old, but I'm running into this problem right now.

I have created a stored function which takes a few IN variables, such as account ID, customer ID and a PIN number, and does checks on this to see if the submitted data is valid. If the data is valid, the procedure updates the account balance to represent a monetary http://stackoverflow.com/questions/26096621/calling-a-procedure-inside-a-function-throws-mysql-error-1422 transaction. It then "returns" whether or not the submitted data was valid. Here is the code for the procedure: DELIMITER // CREATE PROCEDURE retrieveMoney ( IN holder INT, IN pin VARCHAR(4), IN account INT, IN amount FLOAT, OUT success INT ) BEGIN START TRANSACTION; SELECT COUNT(id) INTO success FROM account_holder WHERE id=holder AND pin=pin; IF success IS NOT NULL THEN IF (SELECT balance-amount FROM account WHERE id=account) >= 0 THEN UPDATE account SET balance = balance-amount WHERE id=account; CALL logTransaction(account,NULL,amount); COMMIT; ELSE ROLLBACK; END IF; ELSE ROLLBACK; END IF; END// DELIMITER ; I wanted to make it easier to view the output of the procedure, and as I'm not allowed to use transactions within a function I chose to write a wrapper function, as follows: DELIMITER // CREATE FUNCTION retrieveMoney ( holder INT, pin VARCHAR(4), account INT, amount FLOAT ) RETURNS INT BEGIN CALL retrieveMoney(holder,pin,account,amount,@success); RETURN @success; END// DELIMITER ; Unfortunately this does not work, and I still get this following error: ERROR 1422 (HY000): Explicit or implicit commit is not allowed in stored function or trigger. Is this because I call the procedure, which contains transactions, inside the function? mysql sql stored-procedures transactions sql-function share|improve this question edited Sep 29 '14 at 9:51 asked Se
stored function or trigger. September 20, 2010October 12, 2010 by Inder I haven't seen this documented in MySQL docs, so I'll share this little hidden nuissance. When compiling a trigger, MySQL throws the following error: Explicit or implicit commit is not allowed in stored https://inderpreetsingh.com/2010/09/20/mysql-trigger-error-explicit-or-implicit-commit-is-not-allowed-in-stored-function-or-trigger/comment-page-1/ function or trigger. What does it mean? The code inside the trigger is doing a commit. Looking at the code for the trigger alone is not enough, you must check all procedure/function calls, because the code inside any http://dba.stackexchange.com/questions/99124/how-to-create-function-using-another-functions-mysql calls could really be (part of) the problem. Problem? The problem is usually we look in our code and find that there are no "explicit" commits. The problem is that there is a implicit commit happening somewhere and stored procedure it is hard to pinpoint where if you didn't know this one hidden fact: Depending on version and storage engine, TRUNCATE can cause the table to be dropped and recreated. This provides a much more efficient way of deleting all rows from a table, but it does perform an implicit COMMIT. You might want to use DELETE instead of TRUNCATE. Moral DELETE FROM tablename rather than TRUNCATE TABLE tablename.
