Any ideas what's wrong with this query? I searched around stackoverflow and it seems everyone is using this and it works.

Run this first to change the delimiter
DELIMITER //
create the trigger
CREATE TRIGGER upd_entry
AFTER UPDATE ON entry FOR EACH ROW
BEGIN
UPDATE entry
SET count = count +1

After change it back
DELIMITER ;
forget ; at end of line

I'm very new to SQL and am having issues with syntax in my triggers. I am trying to set a minimum rating of 1 and a maximum rating of 5 for horses after a race. The problem seems to be with the IF statement.
Any help would be greatly appreciated.
CREATE TRIGGER new_rating
AFTER insert on stats
FOR EACH ROW
BEGIN
IF (new.rating > 5) THEN
SET new.rating = 5
ELSEIF (new.rating < 1) THEN
SET new.rating = 1
END IF;
END; //
ERROR 1362 (HY000): Updating of NEW row is not allowed in after trigger
This is the error. It means you can't use SET to change any of the values of the row you are inserting, because in an AFTER INSERT trigger, the row has already been inserted. You would have to do this in a BEFORE INSERT trigger for this to work.
You should read https://dev.mysql.com/doc/refman/8.0/en/trigger-syntax.html which says:
Such a SET statement has no effect in an AFTER trigger because the row change will have already occurred.
If I correct this and change it to a BEFORE INSERT trigger, I get this error:
ERROR 1064 (42000): 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 'ELSEIF (new.rating < 1) THEN ...
I notice you did not end the SET statement with a semicolon. This is necessary to terminate every statement in the trigger, including SET statements.
Here's the trigger that works:
CREATE TRIGGER new_rating BEFORE insert on stats
FOR EACH ROW BEGIN
IF (new.rating > 5) THEN
SET new.rating = 5;
ELSEIF (new.rating < 1) THEN
SET new.rating = 1;
END IF;
END
Here is my trigger, I am getting the MySQL syntax error. I wanted to reduce the balance from sms_index table sms_count column value.
CREATE TRIGGER sms_log_update AFTER UPDATE ON sms_index
FOR EACH ROW
BEGIN
IF NEW.approved_status = '1' THEN
UPDATE sms_package SET balance = (balance - OLD.sms_count) WHERE group_id = OLD.ins_group_id;
END IF;
END;
Error Message:
#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
Your code looks correct, except for the possible problem of the delimiter. Try the following:
DELIMITER //
CREATE TRIGGER sms_log_update AFTER UPDATE ON sms_index
FOR EACH ROW
BEGIN
IF NEW.approved_status = '1' THEN
UPDATE sms_package SET balance = (balance - OLD.sms_count)
WHERE group_id = OLD.ins_group_id;
END IF;
END;//
DELIMITER ;
From the documentation:
However, just as for stored routines, if you use the mysql program to define a trigger that executes multiple statements, it is necessary to redefine the mysql statement delimiter so that you can use the ; statement delimiter within the trigger definition.
I have two table stock detail and purchase.
When I'm trying to create a trigger on the table purchase it will seems an error 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 '' at line 3 "
Hear is my code
create TRIGGER afterinsert after insert on purchase for each row
BEGIN
set #qnty=(select quantity from stock_detail where brand_name = new.brand);
if(#qnty>=1) then
update stock_detail set quantity=#qnty+new.quanty;
end if;
END;
Try this:
delimiter //
create TRIGGER afterinsert after insert on purchase for each row
BEGIN
set #qnty=(select quantity from stock_detail where brand_name = new.brand);
if(#qnty>=1) then
update stock_detail set quantity=#qnty+new.quanty;
end if;
END;//
delimiter ;

Hi i'm trying to create below trigger
CREATE TRIGGER TRIGBEFORE INSERT ON employee
FOR EACH
ROW
BEGIN
UPDATE employee SET userId = userId +1 WHERE userId >1;
END
it is giving me below mysql error, please suggest what is wrong in it.
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
you forgot to set the delimiter and misspelled a word:
delimiter |
CREATE TRIGGER TRIG BEFORE INSERT ON employee
FOR EACH ROW BEGIN
UPDATE employee SET userId = userId +1 WHERE userId >1;
END;
|
delimiter ;
If you don't set another delimiter than ; the statement will end at the first ; and your trigger definition will be incomplete. You need to tell MySQL that the stamentment should end at the delimiter you defined. After that you can set the delimiter back with delimiter ;
I think you have a typo mistake TRIGBEFORE: manual here
CREATE TRIGGER trigger_name BEFORE INSERT ON ...
Running on MySQL 5.5.9 with InnoDB.
I created the following trigger:
CREATE TRIGGER TRIGGER_Products_Insert
AFTER INSERT ON Products
FOR EACH ROW
BEGIN
UPDATE Products
SET current = 0
WHERE id = new.id
AND current = 1
AND autonumber <> new.autonumber
END;
MySQLWorkbench shows a syntax error on the last line, and executing this throws the following error
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' at line 11
Where is my error?
http://dev.mysql.com/doc/refman/5.5/en/create-trigger.html
DELIMITER |
CREATE TRIGGER TRIGGER_Products_Insert AFTER INSERT ON Products

DELIMITER ;
You are missing a ; before your END keyword:
CREATE TRIGGER TRIGGER_Products_Insert
AFTER INSERT ON Products
FOR EACH ROW
BEGIN
UPDATE Products
SET current = 0
WHERE id = new.id
AND current = 1
AND autonumber <> new.autonumber;
END;
