I am trying to fetch some values from php page and perform trigger in mysql database. Which is as below:
DELIMITER $$
DROP TRIGGER /*!50032 IF EXISTS */ `test`.`MysqlTrigger`$$
CREATE
/*!50017 DEFINER = 'root'#'localhost' */
TRIGGER `MysqlTrigger` AFTER INSERT OR UPDATE ON `table2`
FOR EACH ROW BEGIN
IF(NEW .flag=0) THEN
INSERT INTO temp(sent,pcount,ncount) VALUES (NEW.sent,NEW.pcount,NEW.ncount);
ELSE
UPDATE temp SET pcount=NEW.pcount AND ncount=NEW.ncount WHERE id = NEW.id;
END IF;
END;
$$
DELIMITER ;
Which gives error:
error Code : 1064
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'or update ON `table2`
FOR EACH ROW BEGIN
if(NEW .flag=0) then
INSERT INTO' at line 3
I tried to change = with =: but error persist. Any idea whaat the prob?
You can't define a trigger for update and insert at the same time. You have to define 2 triggers:
CREATE TRIGGER `Mysql_insert_Trigger` AFTER INSERT ON `table2` ...
CREATE TRIGGER `Mysql_update_Trigger` AFTER UPDATE ON `table2` ...
I count do it. There was problem in syntax. Here is the correct which perform update insert at same moment in different table and update-inset on same table but with if else:
DELIMITER $$
DROP TRIGGER /*!50032 IF EXISTS */ `test`.`MysqlTrigger2`$$
CREATE
/*!50017 DEFINER = 'root'#'localhost' */
TRIGGER `MysqlTrigger2` AFTER INSERT ON `table2`
FOR EACH ROW BEGIN
IF 'flag'=1 THEN
UPDATE record SET sent=NEW.sent WHERE id=NEW.id;
ELSE
INSERT INTO record VALUES (id,NEW.sent);
INSERT INTO temp VALUES ()
END IF;
END;

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 ;
Screen shot with sequel pro
I have goods_input and goods_input_price tables and want to calculate a total amount when inserting a new row in goods_input.
Trigger is the following:
DELIMITER $$
USE `gym`$$
DROP TRIGGER /*!50032 IF EXISTS */ `total`$$
CREATE
/*!50017 DEFINER = 'root'#'localhost' */
TRIGGER `total` BEFORE INSERT ON `goods_input`
FOR EACH ROW BEGIN
SET new.goods_input_total_amount=new.goods_input_quantity*goods_input_price.`price_goods_input_price`
WHERE goods_input.`id_goods_input_price`=goods_input_price.`id_goods_input_price`;
END;
$$
DELIMITER ;
This is the error message:
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 'where
goods_input.id_goods_input_price=goods_input_price.`id_goods_input_price' at line 6
The set statement does not have a where clause. If you want data from another table, then you need to fetch them via a select into variables in the trigger.
CREATE
/*!50017 DEFINER = 'root'#'localhost' */
TRIGGER `total` BEFORE INSERT ON `goods_input`
FOR EACH ROW BEGIN
DECLARE input_price integer; /*use whatever datatype you have in your db for the price */
SELECT price_goods_input_price INTO input_price FROM goods_input_price
WHERE id_goods_input_price=NEW.id_goods_input_price LIMIT 1;
SET new.goods_input_total_amount=new.goods_input_quantity*input_price;
END$$
I'm trying to create a trigger with a definer and some simple action inside, but doesn't get accepted by mysql and freezes the phpMyadmin without giving an error. Can someone help me to find the mistake
delimiter //
CREATE TRIGGER log_items after insert on Profiles
FOR EACH ROW
IF USER() LIKE 'admin#%' THEN
begin
INSERT INTO ItemsLog (`record_id`, `record_time`) VALUES (NEW.id, now());
end; //
END IF;
delimiter ;
Here is full trigger code that is accepted by phpmyadmin. It was generated when using the sql ide: SQLyog.
DELIMITER //
USE `testmysql`//
DROP TRIGGER /*!50032 IF EXISTS */ `log_items`//
CREATE
DEFINER = 'test'#'localhost'
TRIGGER `log_items` AFTER INSERT ON `profiles`
FOR EACH ROW IF USER() LIKE 'admin#%' THEN
BEGIN
INSERT INTO ItemsLog (`record_id`, `record_time`) VALUES (NEW.id, NOW());
END;
END IF;
//

I am trying to implement a trigger in MySQL that will automatically add/modify a column when another one is added/modified. Basically I want it to save a type as a slug in the type_sanitized column when a value is added/modified into type.
This is my initial try:
DROP TRIGGER IF EXISTS ArticleTypes.insert_sanitized_article_type;
CREATE TRIGGER 'insert_sanitized_article_type'
AFTER INSERT
ON 'ArticleTypes'
FOR EACH ROW
SET NEW.type_sanitized = LOWER(REPLACE(TRIM(NEW.type), ' ', '-'));
DROP TRIGGER IF EXISTS ArticleTypes.update_sanitized_article_type;
CREATE TRIGGER 'update_sanitized_article_type'
AFTER UPDATE
ON 'ArticleTypes'
FOR EACH ROW
SET NEW.type_sanitized = LOWER(REPLACE(TRIM(NEW.type), ' ', '-'));
After seeing suggestions online, I have tried adding delimiters like this:
DROP TRIGGER IF EXISTS ArticleTypes.insert_sanitized_article_type;
DELIMITER $$
CREATE TRIGGER 'insert_sanitized_article_type'
AFTER INSERT
ON 'ArticleTypes'
FOR EACH ROW
BEGIN
SET NEW.type_sanitized = LOWER(REPLACE(TRIM(NEW.type), ' ', '-'));
END$$
DELIMITER ;
DROP TRIGGER IF EXISTS ArticleTypes.update_sanitized_article_type;
DELIMITER $$
CREATE TRIGGER 'update_sanitized_article_type'
AFTER UPDATE
ON 'ArticleTypes'
FOR EACH ROW
BEGIN
SET NEW.type_sanitized = LOWER(REPLACE(TRIM(NEW.type), ' ', '-'));
END$$
DELIMITER ;
I get the following error for both of them:
#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 ''insert_sanitized_article_title'
AFTER INSERT
ON 'ArticleTypes'
FOR EACH ROW
BE' at line 1
This is my first time creating triggers in MySQL so it might be obvious but I haven't been able to figure it out in 2 hours of searching so any help would be greatly appreciated.
Remove the apostrophes.
DROP TRIGGER IF EXISTS ArticleTypes.insert_sanitized_article_type;
DELIMITER $$
CREATE TRIGGER insert_sanitized_article_type
AFTER INSERT
ON ArticleTypes
FOR EACH ROW
BEGIN
SET #type_sanitized = LOWER(REPLACE(TRIM(#type), ' ', '-'));
END$$
DELIMITER ;
DROP TRIGGER IF EXISTS ArticleTypes.update_sanitized_article_type;
DELIMITER $$
CREATE TRIGGER update_sanitized_article_type
AFTER UPDATE
ON ArticleTypes
FOR EACH ROW
BEGIN
SET #type_sanitized = LOWER(REPLACE(TRIM(#type), ' ', '-'));
END$$
DELIMITER ;
I would like to check if a record is being created with a user id, if not then generate one. I can't figure out what I'm doing wrong?
delimiter $$
DROP TRIGGER IF EXISTS init_uuid_users;
CREATE TRIGGER init_uuid_users BEFORE INSERT ON `users`
FOR EACH ROW BEGIN
IF (NEW.username IS NULL) THEN
SET NEW.username = UUID();
END IF;
END;
$$
delimiter ;
DROP TRIGGER IF EXISTS init_uuid_users;
put it before delimiter.
And remove ; after END.
