I'm trying to create a trigger to validate an email address in a customer table, but am getting the error
syntax error, unexpected END, expecting ';'
My code is as follows:
CREATE TRIGGER insert_validation_email
BEFORE INSERT ON customer FOR EACH ROW
BEGIN
IF (NEW.CustomerEmail NOT REGEXP '^[^#]+#[^#]+\.[^#]{2,}$')
THEN
SIGNAL SQLSTATE '45000'
SET MESSAGE_TEXT = 'Cannot add or update row: invalid email address'
END* IF
END
END* is where it is underlined with the error (the asterisk is not there)
There are other validation triggers which will be included, so the begin and end statement is needed
Fixed by changing delimiter and putting ; after if block and final END. Thanks Gordon Linoff and a_horse_with_no_name for helping
DELIMITER $$
CREATE TRIGGER before_insert_email
BEFORE INSERT ON customer FOR EACH ROW
BEGIN
IF (NEW.CustomerEmail NOT REGEXP '^[^#]+#[^#]+\.[^#]{2,}$')

SIGNAL SQLSTATE '45000'
SET MESSAGE_TEXT = 'Cannot add or update row: invalid email address';

I have table users with two fields id (numeric) and email (with full email adress) how to add trigger which can prevent adding new email records with specific domains eg: *#somedomain.com?
The trigger would look like this:
DELIMITER $$
CREATE TRIGGER USER_INSERT BEFORE INSERT ON USER
FOR EACH ROW
BEGIN
IF new.email like '%#somedomain.com' THEN
SIGNAL sqlstate '99999'
SET message_text = 'Invalid domain';
END IF;
END$$
DELIMITER ;
Please try this:
DELIMITER $$
CREATE TRIGGER example_before_insert_reject_domains
BEFORE INSERT ON example_tbl FOR EACH ROW
BEGIN
IF NEW.email LIKE '%#somedomain.com'
THEN
SIGNAL SQLSTATE '45000'
SET MESSAGE_TEXT = 'Cannot add or update row: invalid domain for email';
END IF;
END;

I am having an error and I can't make sense of it. Here is the code for my trigger:
CREATE TRIGGER before_insert_test
BEFORE INSERT ON player_totals FOR EACH ROW
BEGIN
IF NEW.Player = 'Player' THEN
SIGNAL SQLSTATE '45000' SET MESSAGE_TEXT = 'basketball-reference duplicate header';
END IF;
END;
I am getting red errors marks in MySQL workbench source code editor for 3 lines. For the line that begins SIGNAL SQLSTATE ..., It says:
Syntax Error: missing 'semicolon'
For the line that reads END IF;, the error says:
Syntax error: END (end) is not valid input as this position.
For the line that reads END;, the error says:
Extraneous input found - expected end of statement
Just not sure how to fix these errors, from what I've seen this looks like the correct syntax...
Try this one, with $$ after END
DELIMITER $$
CREATE TRIGGER before_insert_test
BEFORE INSERT ON player_totals
FOR EACH ROW
BEGIN
IF NEW.Player = 'Player' THEN
SIGNAL SQLSTATE '45000' SET MESSAGE_TEXT = 'basketball-reference duplicate header';
END IF;
END; $$

my schema is middleweight(mname, mwins, mlosses, mdraws, mweight, mcountry, mage, mheight)
I am completely lost cant seem to find the problem.
delimiter//
CREATE TRIGGER tr_middlewegiht_u
BEFORE update on middleweight
for each row
begin
IF (new.mweight>185) THEN
SIGNAL sqlstate '45000'
set message_text = 'The fighters in the wrong weight class.';
END if;
END//
delimiter;
You should maintain a space between 'delimiter' key word and its values '//', and ';'
Unless which it is a 1064 syntax error.
Example:
delimiter // -- <--- observe the space here. It is a MUST
-- your trigger definition
end;
//
delimiter ; -- <--- maintain space here too. This too is a MUST
CREATE TRIGGER test BEFORE INSERT ON MYTABLE
FOR EACH ROW
BEGIN
IF break < 0 THEN
SIGNAL sqlstate '45000'
set message_text = 'ERROR';
END IF;
END;
This throws a syntax error and I'm not able to find it.
You need to change the delimiter that MySQL is using as an end-of-line marker. You need to do this for CREATE TRIGGER and CREATE PROCEDURE because if you don't MySQL will treat the first semi-colon as the end of the command and finish processing it prematurely - hence the syntax error.
Do this:
DELIMITER $$
CREATE TRIGGER test BEFORE INSERT ON MYTABLE
FOR EACH ROW
BEGIN
IF break < 0 THEN
SIGNAL sqlstate '45000'
set message_text = 'ERROR';
END IF;
END$$
DELIMITER ;
Now, MySQL will continue processing your CREATE TRIGGER command until it reaches $$, and include the semi-colons as part of the trigger script. Note that I've set the delimiter back to semicolon when I'm finished.
I am trying to setup a trigger so an insert does not occur if a condition is not met.
I thought the below was the way to do it but i am not sure
I am getting an error
/* SQL Error (1407): Bad SQLSTATE: '45000 ' */
Can anyone let me know why I am getting this error and the best way for me to prevent an insert if the condition is not met in mysql.

SQLSTATE is required to be a a 5 character string unless previously declared using DECLARE ... CONDITION;
SIGNAL SQLSTATE '45000 'SET MESSAGE_TEXT = error_msg;
You're trying to set SQLSTATE to '45000 ' (note the space) which is 6 characters long. Fix the spacing and you should not see the message again (it is also reflected in your error message, but the space is a bit hard to see)
