is not working why what is actual syntax mysqlversion 5.0
The 'IF EXISTS' clause is not supported in DROP TRIGGER statement.
And add a delimiter after 'DROP TRIGGER...' statement.
EDIT
Read the information about trigger's existance from information_schema.triggers table; then drop trigger. Do it in the application or write a stored procedure.
Example:
DELIMITER $$
CREATE PROCEDURE drop_trigger()
BEGIN
SET #exist = NULL;
SELECT 1
INTO
#exist
FROM
information_schema.triggers
WHERE
trigger_schema = 'test'
AND trigger_name = 'trigger1';
IF #exist IS NOT NULL THEN
DROP TRIGGER test.trigger1;
END IF;
END
$$
DELIMITER ;

I have below trigger code but It give me error. I can't figure out what is wrong with my code.
DROP TRIGGER IF EXISTS `user_has_voice_queues_rt_update`;
CREATE DEFINER=`root`#`localhost`
TRIGGER `user_has_voice_queues_rt_update`
BEFORE UPDATE ON `user_has_voice_queues_rt`
FOR EACH ROW begin
if(new.pause='0') then
Set new.penalty = (select max(penalty) from user_has_voice_queues_rt) + 1;
end if;
Try this:
DROP TRIGGER IF EXISTS `user_has_voice_queues_rt_update`;
DELIMITER $$
CREATE DEFINER=`root`#`localhost`
TRIGGER `user_has_voice_queues_rt_update`
BEFORE UPDATE ON `user_has_voice_queues_rt`
FOR EACH ROW begin
if(new.pause='0') then
Set new.penalty = (select max(penalty) from user_has_voice_queues_rt) + 1;
end if;
END $$
DELIMITER ;
I have created the following trigger in mysql:
DELIMITER $$
CREATE TRIGGER `some_trigger` AFTER INSERT ON db1.table
FOR EACH ROW
BEGIN
IF NEW.userid = 'certain_id' THEN
INSERT INTO db2.table
SET
value1 = NEW.value,
value2 = NEW.value;
END IF;
END $$
DELIMITER ;
The above statement works if I remove the if statement. Additionally no syntax errors are encountered when this trigger is added to the db. Any idea what is wrong with the if statement that is not allowing it to insert entries with value 'certain_id' in column userid when added to db1.table??
Try this it should work..
DELIMITER $$
CREATE TRIGGER `some_trigger` AFTER INSERT ON `db1`.`table`
FOR EACH ROW
BEGIN
IF (NEW.userid = 'certain_id') THEN
INSERT INTO `db2`.`table` (value1, value2)
VALUES (NEW.value1,NEW.value2);
END IF;
END $$
DELIMITER ;
I've been looking at other stackoverflow questions here but cant seem to find my fault. I think its syntax-error related. On what part did I got wrong?
DELIMITER $$
DROP TRIGGER IF EXISTS keisan
CREATE TRIGGER keisan AFTER INSERT ON profitdb
FOR EACH ROW
BEGIN
DECLARE shinAgentPercent;
SET #shinAgentPercent:=`AgentRisk`-`SubAgentRisk`;
SET NEW.`SubAgentProfit` = `Profit`*(`SubAgentRisk`/100);
SET NEW.`AgentProfit` = `Profit`*(#shinAgentPercent/100);
END;
$$
Firstly, you need a closing statement indication after drop ... command.
DROP TRIGGER IF EXISTS keisan $$
Secondly, I suggest you to go with a BEFORE INSERT trigger to set expression values for other columns of the tables.
Example:
DELIMITER $$
DROP TRIGGER IF EXISTS keisan $$
CREATE TRIGGER keisan BEFORE INSERT ON profitdb
FOR EACH ROW BEGIN
SET #shinAgentPercent := NEW.AgentRisk - NEW.SubAgentRisk;
SET NEW.SubAgentProfit := NEW.Profit * ( NEW.SubAgentRisk / 100 );
SET NEW.AgentProfit := NEW.Profit * ( #shinAgentPercent / 100 );
END;
$$
-- now reset the delimiter to defaut
DELIMITER ;
Don't you need an end-of-statement after your DROP TRIGGER?
DROP TRIGGER IF EXISTS keisan$$
I would like to check if a record is being created with a user id, if not then generate one. I can't figure out what I'm doing wrong?
delimiter $$
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;
$$
delimiter ;
DROP TRIGGER IF EXISTS init_uuid_users;
put it before delimiter.
And remove ; after END.
I need to execute a command similar to the following not inside a procedure but inside a simple sql file for mysql 5.xx
IF EXISTS (SELECT * FROM INFORMATION_SCHEMA.TRIGGERS WHERE TRIGGER_NAME = 'tr_fnninio_censopersona_ins') THEN
DROP TRIGGER tr_fnninio_censopersona_ins;
END IF;
Why not just
DROP TRIGGER IF EXISTS tr_fnninio_censopersona_ins;
MySQL drop trigger doc
You can use like this,
DROP TRIGGER IF EXISTS tr_fnninio_censopersona_ins;
DELIMITER $$
CREATE TRIGGER tr_fnninio_censopersona_ins
BEFORE INSERT ON `your_table` FOR EACH ROW
BEGIN
SET NEW.INSERTED= NOW();
END$$
DELIMITER ;
