When I try and run my table/trigger creation script, I get the following error:
ERROR 1064 (42000) at line 19: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'SET NEW.fines_remaining = NEW.total_fines;
END IF;
END' at line 5
The following is the CREATE TRIGGER code which is causing the error:
DELIMITER //
CREATE TRIGGER fines_trigger BEFORE INSERT ON student
FOR EACH ROW
BEGIN
IF TUPLE.fines_remaining > TUPLE.total_fines
SET NEW.fines_remaining = NEW.total_fines;
END IF;
END; //
DELIMITER ;
I can't figure out why this is happening, I feel like the syntax is fine, but it's obviously not since there's some error being thrown.
EDIT: Immediately after posting this I notice that I still have these TUPLE 'variables' that I was using before I figured out about 'OLD' and 'NEW'. I'm changing them and will update momentarily.
You are missing then after the if condition
DELIMITER //
CREATE TRIGGER fines_trigger BEFORE INSERT ON student
FOR EACH ROW
BEGIN
IF new.fines_remaining > old.total_fines then
SET NEW.fines_remaining = NEW.total_fines;
END IF;
END; //
DELIMITER ;
Also I have changed TUPLE with new and old in the above trigger, you may need to adjust the logic as per your need.

This is my first time trying to create a MySql trigger but I'm running into syntax errors that I can't identify. I am trying to have the trigger insert a calculated value when a row is updated. Below is my code, but I keep getting syntax errors when I try to execute it, and I cannot see where the error is. Can someone please look, what am I doing wrong?
DROP TRIGGER ins_cop_dhw;
CREATE TRIGGER ins_cop_dhw BEFORE INSERT ON `2017010001_data`
FOR EACH ROW
BEGIN
IF (NEW.`_007E` = 1 AND `_00A2` > 0) THEN
SET NEW.`_00B7` = NEW.`_0096` / NEW.`_00A2`;
END IF;
IF (NEW.`_007D` = 1 AND `_00A2` > 0) THEN
SET NEW.`_00B8` = (NEW.`_0096` / NEW.`_00A2`);
END IF;
END;
Here is the error I get in MySQL Workbench, but it's not much help. :/
Error Code: 1064. You have an error in your SQL syntax; check the manual
that corresponds to your MySQL server version for the right syntax to
use near '' at line 5
MySQL Workbench highlights the end of line 6 as the start of the syntax error.
As said by #Akina I was missing the delimiter statements. Here is fixed code.
delimiter //
DROP TRIGGER ins_cop_dhw;
CREATE TRIGGER ins_cop_dhw BEFORE INSERT ON `2017010001_data`
FOR EACH ROW
BEGIN
IF (NEW.`_007E` = 1 AND NEW.`_00A2` > 0) THEN
SET NEW.`_00B7` = NEW.`_0096` / NEW.`_00A2`;
END IF;
IF (NEW.`_007D` = 1 AND NEW.`_00A2` > 0) THEN
SET NEW.`_00B8` = (NEW.`_0096` / NEW.`_00A2`);
END IF;
END//
delimiter ;
As per the advice of #Akina I read the Create Procedure documentation from the dev.mysql.com site and the below quote highlighted the importance of using delimiter
The example uses the mysql client delimiter command to change the statement delimiter from ; to // while the procedure is being defined. This enables the ; delimiter used in the procedure body to be passed through to the server rather than being interpreted by mysql itself. See Section 25.1, “Defining Stored Programs”.
I am using phpmyadmin and got a syntax error from my trigger part. I followed examples online but didn't see anything wrong. Does anyone see the syntax error? Thank you in advance.
Here is my code:
CREATE TRIGGER INSERT_T BEFORE INSERT ON dataT
for each row begin
IF(NEW.id IS NOT NULL)
SET NEW.id = 9999;
END IF
end;
mysql reports that:
#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'SET NEW.id = 9999' at line 4
.
Missing THEN keyword.
MySQL Reference Manual:
IF Syntax https://dev.mysql.com/doc/refman/5.7/en/if.html
And for your next questions. Yes, you need a semicolon following the END IF
And you need to specify a delimiter other than the default semicolon. e.g.
DELIMITER $$
CREATE TRIGGER ...
END$$
DELIMITER ;

My Trigger
CREATE TRIGGER `register_notification_after_register`
`AFTER INSERT ON register FOR EACH ROW BEGIN
Set #notification = CONCAT('New Member Register. Membership Code is',' ',new.membership_no,'.');
Set #notificationfor =CONCAT('New Membership');
call notification_masterAddUpdate(1,#notification,#notificationfor,new.reg_date,1);
END
try this:
DELIMITER $$
CREATE TRIGGER `register_notification_after_register`

Set #notification = CONCAT('New Member Register. Membership Code is',' ',new.membership_no,'.');
Set #notificationfor =CONCAT('New Membership');
call notification_masterAddUpdate(1,#notification,#notificationfor,new.reg_date,1);
END
$$ -- I am done server, end of block
DELIMITER ;
you had an extra backtick on line two. One needs to set the DELIMITER to block the whole thing. With create event, create stored proc, create trigger, delimiters clue the server into when the whole chunk is done. Remember that the ; ends a statement. The delimiter statement suspends that in favor of something else, then resets at end of block
Using MySQL55 on MySQLWorkbench 6.2 for Windows,
DROP TRIGGER IF EXISTS `maxBBLimit`;
CREATE TRIGGER `maxBBLimit`
AFTER UPDATE ON locationobject
FOR EACH ROW
IF locationobject.boxLowY > 1000 THEN CALL RaiseException();
END IF;
Assuming that locationobject has a unsigned int variable called boxLowY that only allows values between 0 and 1000, and if it is above this range, it calls RaiseException().
My workspace refuses to compile because of these errors:
17:43:40 CREATE TRIGGER `maxBBLimit` AFTER UPDATE ON locationobject FOR EACH ROW IF locationobject.boxLowY > 1000 THEN CALL RaiseException() Error Code: 1064. You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 4 0.000 sec
^ This one has a red squiggle under ) after RaiseException(
17:43:40 ; END IF Error Code: 1064. You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '; END IF' at line 1 0.000 sec
^ This one has a red squiggle under END in the END IF statement;
Anyone have any suggestions how to get this code to compile?
Triggers definitions should be surrounded by delimiter statements.
In addition, you refer to the table for the trigger using new. And, you want a before update trigger. If you fail after the update, the bad value will still go into the database. And, you normally use signal to return an error. So, if I haven't missed anything:
DELIMITER $$
DROP TRIGGER IF EXISTS `maxBBLimit` $$
CREATE TRIGGER `maxBBLimit`
AFTER UPDATE ON locationobject
FOR EACH ROW
IF new.boxLowY > 1000 THEN
SIGNAL SQLSTATE '4500' SET MESSAGE_TEXT = 'boxLowY out of range';
END IF$$
DELIMITER ;
I want to trigger the table after update only if any change is made in the table.
I tried this
but it is giving error.
My code is
CREATE TRIGGER Trans_SubCategory_update AFTER UPDATE ON Trans_SubCategory
FOR EACH ROW
BEGIN
IF NEW.ts <> OLD.ts THEN
INSERT INTO Sync_activities (table_name,table_id,admin_id,action)
VALUES('Trans_SubCategory',New.id,New.admin_id,'update');
END IF;
END;
It is giving error
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 6 .
But if I use
CREATE TRIGGER Trans_SubCategory_update AFTER UPDATE ON Trans_SubCategory
FOR EACH ROW
INSERT INTO Sync_activities (table_name,table_id,admin_id,action)
VALUES('Trans_SubCategory',New.id,New.admin_id,'update');
I add the trigger but triggers even if no change is made in table.
The thing is - you're forgetting to set proper delimiter. Your first syntax contains multiple operators inside trigger - and they need to be delimited by ; - but you're not changing global delimiter - thus, MySQL treats that as syntax end - and, therefore, that's an error (because trigger isn't completed, obviously).
Your second syntax is executed completely since it has only one operator (and that stands for trigger end as well) - you've not enclosed it by BEGIN..END
To fix the issue, just do:
DELIMITER //
CREATE TRIGGER Trans_SubCategory_update AFTER UPDATE ON Trans_SubCategory
FOR EACH ROW
BEGIN
IF NEW.ts != OLD.ts THEN
INSERT INTO Sync_activities (table_name,table_id,admin_id,action) VALUES ('Trans_SubCategory', NEW.id, NEW.admin_id,'update');
END IF;
END;//
DELIMITER ;
