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.

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 27.2k32184242 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 functi

THEN conditional INSERT. Try modifying your INSERT statement with an EXISTS like DROP TRIGGER IF EXISTS `insertImage`; CREATE TRIGGER `insertImage` AFTER INSERT ON `incidentreport` FOR EACH ROW BEGIN INSERT INTO incidentimg(incidentImgId, imgUrl) SELECT NEW.incidentReportId, 'images/no-image.png' FROM DUAL WHERE EXISTS ( SELECT 1 FROM incidentimg LEFT JOIN incidentreport ON incide
like the INSERT, UPDATE, and DELETE. When I said, "Yes, you can put DML statements inside functions." They showed me the error they encountered, which is only raised at compilation when you put an explicit COMMIT statement or a Data Definition Language (DDL) statement (CREATE, ALTER, DROP, or RENAME) inside a MySQL function. The actual error message displayed is: ERROR 1422 (HY000): Explicit OR implicit commit IS NOT allowed IN stored FUNCTION OR TRIGGER. While an explicit COMMIT is obvious when placed inside a function, the implicit COMMIT statement isn't obvious unless you know a DDL statement generates one. This means you can't include any DDL statement inside a stored function. The following example shows how a DDL statement creates an immediate implicit COMMIT. It requires two sessions and Transaction Control Language (TCL) statements. In session one, create a table, start a transaction scope, and insert one row into the table: -- Create a table. CREATE TABLE message ( message_id INT UNSIGNED PRIMARY KEY AUTO_INCREMENT , message_text VARCHAR(20)); -- Start a transaction context. BEGIN WORK; -- Insert a row into the MESSAGE table. INSERT INTO message (message_text) VALUES ('Implicit Commit?'); In session two, the empty set is displayed when you query the MESSAGE table. Returning to session one, add a new column to the MESSAGE table with this statement: ALTER TABLE message ADD (sent DATETIME); The ALTER statement automatically makes current any pending data changes, effectively committing the record from session one. You can return to the second session and query the table you get the following results: +------------+------------------+------+ | message_id | message_text | sent | +------------+------------------+------+ | 1 | Implicit Commit? | NULL | +------------+------------------+------+ When you embed DML statements inside functions, they rely on automatic commit behaviors or an external transaction scope. This function compiles and returns 1 when successful and 0 when unsuccessful, which effectively controls all error conditions within the function: CREATE FUNCTION modifies_data ( pv_message CHAR(20) ) RETURNS INT MODIFIES SQL DATA BEGIN /* Declare Boolean-like variables as FALSE. */ DECLARE lv_return_value INT DEFAULT FALSE; DECLARE lv_error_value INT DEFAULT FALSE; /* Declare a generic exit handler to reset error co
