I want to add a trigger in my database in phpmyadmin to rollback an insertion into the table if a particular attribute is greater than 100.
Here is my code that I wrote in the window for define in the "Add Trigger" window:
BEGIN
ROLLBACK IF NEW.max_allowed > 100
END;
I am getting this error:
MySQL said: #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 'IF NEW.max_allowed > 100 END' at line 2
Can someone please suggest what I'm missing?
ROLLBACK can't be used together with IF in the same statement.
Check the documentation.
I suggest this code for your trigger:
BEGIN
IF NEW.max_allowed > 100 THEN
ROLLBACK;
END IF;
END;

I am getting an error in my mySql query when i execute my create trigger query in mysql using phpmyadmin which is provided below.
Error:
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
MySql Query:
CREATE TRIGGER Trigger_INSERT_club_app_member_contact_info After INSERT ON club_app_member_contact_info
FOR EACH ROW
BEGIN
INSERT INTO club_app_events_list(type_id,event_title,event_description,event_date,event_time,event_venue)
values(1,CONCAT('Happy Birthday ',NEW.title,NEW.name),NEW.mobile_no,NEW.dob,'8.30AM','');
IF NEW.ismarried == 'Yes' THEN
INSERT INTO club_app_events_list(type_id,event_title,event_description,event_date,event_time,event_venue)
values(1,CONCAT('Happy Birthday ',NEW.title_for_spouse,NEW.nameOf_spouse,'Spouse of (',NEW.title,NEW.name,')'),NEW.spouse_mobileNo,NEW.spouse_dob,'8.30AM','');
INSERT INTO club_app_events_list(type_id,event_title,event_description,event_date,event_time,event_venue)

END IF
END
I don't know what's wrong with my query.Can anyone help me to find a solution.
Few thing i noticed IF NEW.ismarried == 'Yes' THEN it should IF NEW.ismarried = 'Yes' THEN BEGIN and END IF should end with semicolon ; although BEGIN end enclose END;
But since i am trying to execute this query using phpmyadmin I have to remove Delimiter from the bottom text box of phpmyadmin.
But note that this is only phpmyadmin analysis warnings not a mysql server response.
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 ;
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 ;
Could someone please tell me what's wrong with my Mysql-syntax in the following trigger?
CREATE TRIGGER hQual AFTER INSERT ON Musikstück FOR EACH ROW BEGIN
IF(length(NEW.bitrate)=4) THEN
IF ((CONVERT(substr(NEW.bitrate,2,3),SIGNED INTEGER))<320) THEN
UPDATE Album SET High_Quality = 0 WHERE Album.Albumname=NEW.Albumname;
END IF
ELSEIF((CONVERT(NEW.bitrate,SIGNED INTEGER))<320) THEN
UPDATE Album SET High_Quality = 0 WHERE Album.Albumname=NEW.Albumname;
END IF
END
It's too late over here, I'm tired and I don't see it :) MySql is just saying:
#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
DELIMITER ||
CREATE TRIGGER `monthly_insert` BEFORE INSERT ON `history_monthly`
FOR EACH ROW
BEGIN
NEW.`uid` = CONCAT(OLD.`year`, OLD.`month`, OLD.`charactersId`);
END;
||
DELIMITER ;
And it returns an 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 '.`uid` = CONCAT(OLD.`year`, OLD.`month`, OLD.`charactersId`);
END' at line 4
It's my first time with triggers and I was doing my best to try to find soultion but I failed ;<
You need to add the word SET in this line:
SET NEW.`uid` = CONCAT(OLD.`year`, OLD.`month`, OLD.`charactersId`);
Also, as the commenter pointed out, there is no OLD value in a BEFORE INSERT trigger.
