I have trouble defining a trigger for a MySQL database. I want to change a textfield before inserting a new row (under a given condition). This is what I have tried:
CREATE TRIGGER add_bcc
BEFORE INSERT ON MailQueue
FOR EACH ROW BEGIN
IF (NEW.sHeaders LIKE "%[email protected]%") THEN
SET NEW.sHeaders = NEW.sHeaders + "BCC:[email protected]";
END IF;
END;
But always I get the error "wrong syntax". I got stuck, what am I doing wrong? I'm using MySQL 5.0.51a-community
BTW: Creating an empty Trigger like this works fine:
CREATE TRIGGER add_bcc
BEFORE INSERT ON MailQueue
FOR EACH ROW BEGIN
END;
But this fails, too:
CREATE TRIGGER add_bcc
BEFORE INSERT ON MailQueue
FOR EACH ROW BEGIN
IF 1=1 THEN
END IF;
END;
It's my first time to use stackoverflow.com, so I'm very excited if it is helpful to post something here :-)
Syntax for creating trigger:CREATE [OR REPLACE ] TRIGGER trigger_name. {BEFORE | AFTER | INSTEAD OF } {INSERT [OR] | UPDATE [OR] | DELETE} [OF col_name]
You need to change the delimiter - MySQL is seeing the first ";" as the end of the CREATE TRIGGER statement.
Try this:
/* Change the delimiter so we can use ";" within the CREATE TRIGGER */
DELIMITER $$
CREATE TRIGGER add_bcc
BEFORE INSERT ON MailQueue
FOR EACH ROW BEGIN
IF (NEW.sHeaders LIKE "%[email protected]%") THEN
SET NEW.sHeaders = NEW.sHeaders + "BCC:[email protected]";
END IF;
END$$
/* This is now "END$$" not "END;" */
/* Reset the delimiter back to ";" */
DELIMITER ;
