I want to create trigger and I have written this query but this does not execute. Please check my query
CREATE
TRIGGER 'blog_after_insert' AFTER INSERT
ON 'blog'
FOR EACH ROW BEGIN
IF NEW.deleted THEN
SET #changetype = 'DELETE';
ELSE
SET #changetype = 'NEW';
END IF;
INSERT INTO audit (blog_id, changetype) VALUES (NEW.id, #changetype);
I am getting this error
#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 ''blog_after_insert' AFTER INSERT
ON 'blog'
FOR EACH ROW BEGIN
IF NEW.del' at line 2
Please run this query
DELIMITER $$
CREATE
TRIGGER blog_after_insert AFTER INSERT
ON blog
FOR EACH ROW BEGIN
IF NEW.deleted THEN
SET #changetype = "DELETE";
ELSE
SET #changetype = "NEW";
END IF;
INSERT INTO audit (blog_id, changetype) VALUES (NEW.id, #changetype);
END$$
DELIMITER ;
Single quotes (') denote string literals - object names, like triggers and tables should use forward quotes, or no quotes at all:
CREATE
TRIGGER blog_after_insert AFTER INSERT -- here
ON blog -- and here
FOR EACH ROW BEGIN
-- rest of code...

I'm trying to create a BEFORE INSERT trigger and getting errors that I don't understand.
The MySQL to create the trigger looks like this:
CREATE TRIGGER `GetPolyLinkID` BEFORE INSERT ON `TableA`
FOR EACH ROW
BEGIN
INSERT INTO TableB () VALUES ();
NEW.PolyLinkID = last_insert_id();
END
The error I'm getting is
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 1
You forgot SET ... begore NEW.PolyLinkID = last_insert_id();
And
For creating complex trigger , you must use the delimiter keyword .
This is a example from rom https://dev.mysql.com/doc/refman/5.6/en/trigger-syntax.html .
delimiter //
CREATE TRIGGER upd_check BEFORE UPDATE ON account
FOR EACH ROW
BEGIN
IF NEW.amount < 0 THEN
SET NEW.amount = 0;
ELSEIF NEW.amount > 100 THEN
SET NEW.amount = 100;
END IF;
END;
//
delimiter ;

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 want to create a trigger to insert a value in another table when a value is inserted in the first table.
So far my trigger looks like this:
CREATE TRIGGER tgIdPass
AFTER INSERT
ON tbuser FOR EACH ROW
BEGIN
DECLARE vIdPass INT
SET vIdPass = NEW.id
INSERT INTO tbpass.fkUser VALUES vIdPass
END
When I try to run the code, it gives this error "#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'SET vIdPass = NEW.id INSERT INTO tbpass.fkUser VALUES vIdPass END' at line 8"
So anyone can illuminate my on why I'm getting this error?
Need DELIMITERs and statement terminators.
DELIMITER //
CREATE TRIGGER tgIdPass
AFTER INSERT
ON tbuser FOR EACH ROW
BEGIN
DECLARE vIdPass INT; -- terminate statements
...
END
//
DELIMITER ;
I receive this 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 6" but can not figure out what is wrong.
(position and points are MEDIUMINT, they are not primary key neither unique)
Anyone?
CREATE TRIGGER pointsAssigns
before INSERT ON MyTable
FOR EACH ROW
BEGIN
IF NEW.position>6 THEN
set NEW.points=5;
END IF;
END;
As #Mihai mentioned either add closing END and change the DELIMITER
DELIMITER //
CREATE TRIGGER pointsAssigns
BEFORE INSERT ON MyTable
FOR EACH ROW
BEGIN
IF NEW.position > 6 THEN
SET NEW.points = 5;
END IF;
END //
DELIMITER ;
Here is a SQLFiddle demo
or make it one-line trigger and then you don't need neither BEGIN...END block nor changing the DELIMITER
CREATE TRIGGER pointsAssigns
BEFORE INSERT ON MyTable
FOR EACH ROW
SET NEW.points = IF(NEW.position > 6, 5, NEW.points);

I'm trying to call a stored procedure to create multiple rows using some of the cell values of the new row inserted in the table resource but I'm getting an error. Here is my query:
CREATE TRIGGER `details` AFTER INSERT ON `resource`
FOR EACH ROW BEGIN
CALL addcopies(NEW.copies, NEW.id, NEW.location);
END;
#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
What am I doing wrong?
delimiter |
CREATE TRIGGER `details` AFTER INSERT ON `resource`
FOR EACH ROW BEGIN
CALL addcopies(NEW.copies, NEW.id, NEW.location);
END
|
delimiter ;
If you don't set another delimiter than ;, then the statement will end at the first ; and your trigger definition will be incomplete. You need to tell MySQL that the statement should end at the delimiter you defined. After that you can set the delimiter back with delimiter ;
