you had an extra backtick on line two. One needs to set the DELIMITER to block the whole thing. With create event, create stored proc, create trigger, delimiters clue the server into when the whole chunk is done. Remember that the ; ends a statement. The delimiter statement suspends that in favor of something else, then resets at end of block

This is my first time trying to create a MySql trigger but I'm running into syntax errors that I can't identify. I am trying to have the trigger insert a calculated value when a row is updated. Below is my code, but I keep getting syntax errors when I try to execute it, and I cannot see where the error is. Can someone please look, what am I doing wrong?
DROP TRIGGER ins_cop_dhw;
CREATE TRIGGER ins_cop_dhw BEFORE INSERT ON `2017010001_data`
FOR EACH ROW
BEGIN
IF (NEW.`_007E` = 1 AND `_00A2` > 0) THEN
SET NEW.`_00B7` = NEW.`_0096` / NEW.`_00A2`;
END IF;
IF (NEW.`_007D` = 1 AND `_00A2` > 0) THEN
SET NEW.`_00B8` = (NEW.`_0096` / NEW.`_00A2`);
END IF;
END;
Here is the error I get in MySQL Workbench, but it's not much help. :/
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 5
MySQL Workbench highlights the end of line 6 as the start of the syntax error.
As said by #Akina I was missing the delimiter statements. Here is fixed code.
delimiter //
DROP TRIGGER ins_cop_dhw;
CREATE TRIGGER ins_cop_dhw BEFORE INSERT ON `2017010001_data`
FOR EACH ROW
BEGIN
IF (NEW.`_007E` = 1 AND NEW.`_00A2` > 0) THEN
SET NEW.`_00B7` = NEW.`_0096` / NEW.`_00A2`;
END IF;
IF (NEW.`_007D` = 1 AND NEW.`_00A2` > 0) THEN
SET NEW.`_00B8` = (NEW.`_0096` / NEW.`_00A2`);
END IF;
END//
delimiter ;
As per the advice of #Akina I read the Create Procedure documentation from the dev.mysql.com site and the below quote highlighted the importance of using delimiter
The example uses the mysql client delimiter command to change the statement delimiter from ; to // while the procedure is being defined. This enables the ; delimiter used in the procedure body to be passed through to the server rather than being interpreted by mysql itself. See Section 25.1, “Defining Stored Programs”.
i wat to create this trigger to set a defaul value for a clomn but i get this message 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 '' at line 4
this is my script :
CREATE TRIGGER trg_set_content_val BEFORE INSERT
ON post_table
FOR EACH ROW BEGIN
set NEW.content = 'mu value here';
END;
You need to set the delimiter to something else than semicolon before the stored program and then change it back:
DELIMITER //
CREATE TRIGGER trg_set_content_val
BEFORE INSERT
ON post_table
FOR EACH ROW BEGIN
set NEW.content = 'mu value here';
END//
DELIMITER ;
Reason:
If you use the mysql client program to define a stored program
containing semicolon characters, a problem arises. By default, mysql
itself recognizes the semicolon as a statement delimiter, so you must
redefine the delimiter temporarily to cause mysql to pass the entire
stored program definition to the server.
To redefine the mysql delimiter, use the delimiter command. The
following example shows how to do this for the dorepeat() procedure
just shown. The delimiter is changed to // to enable the entire
definition to be passed to the server as a single statement, and then
restored to ; before invoking the procedure. This enables the ;
delimiter used in the procedure body to be passed through to the
server rather than being interpreted by mysql itself.
I have a problem with this, and I keep getting this error
MySQL said: Documentation
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.
Do you have any ideas for why I keep getting this error?
DROP PROCEDURE IF EXISTS `prn_insert`;
CREATE PROCEDURE `prn_insert`(id int, name text, description text)
BEGIN
insert into test
select id,name,description;
END
The semicolon is ending the CREATE PROCEDURE statement. To get the entire statement, use a delimiter other than a semicolon. We frequently use $$ (two dollar signs) as a delimiter, but you can use any character sequence that doesn't appear within the statement(s) you want to execute.
For example:
DELIMITER $$
DROP PROCEDURE myproc $$
CREATE PROCEDURE myproc(arg INT)
BEGIN
DECLARE i INT DEFAULT 0;
SET i = 1;
END$$
DELIMITER ;
Once the new delimiter is set, it stays in effect until it's changed to something else. So. we usually want to set it back to semicolon immediately after the `CREATE PROCEDURE' statement.
When I try and run my table/trigger creation script, I get the following error:
ERROR 1064 (42000) at line 19: 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.fines_remaining = NEW.total_fines;
END IF;
END' at line 5
The following is the CREATE TRIGGER code which is causing the error:
DELIMITER //
CREATE TRIGGER fines_trigger BEFORE INSERT ON student
FOR EACH ROW
BEGIN
IF TUPLE.fines_remaining > TUPLE.total_fines
SET NEW.fines_remaining = NEW.total_fines;
END IF;
END; //
DELIMITER ;
I can't figure out why this is happening, I feel like the syntax is fine, but it's obviously not since there's some error being thrown.
EDIT: Immediately after posting this I notice that I still have these TUPLE 'variables' that I was using before I figured out about 'OLD' and 'NEW'. I'm changing them and will update momentarily.
You are missing then after the if condition
DELIMITER //
CREATE TRIGGER fines_trigger BEFORE INSERT ON student
FOR EACH ROW
BEGIN
IF new.fines_remaining > old.total_fines then
SET NEW.fines_remaining = NEW.total_fines;
END IF;
END; //
DELIMITER ;
Also I have changed TUPLE with new and old in the above trigger, you may need to adjust the logic as per your need.
I want to trigger the table after update only if any change is made in the table.
I tried this
but it is giving error.
My code is
CREATE TRIGGER Trans_SubCategory_update AFTER UPDATE ON Trans_SubCategory
FOR EACH ROW
BEGIN
IF NEW.ts <> OLD.ts THEN
INSERT INTO Sync_activities (table_name,table_id,admin_id,action)
VALUES('Trans_SubCategory',New.id,New.admin_id,'update');
END IF;
END;
It is giving error
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 if I use
CREATE TRIGGER Trans_SubCategory_update AFTER UPDATE ON Trans_SubCategory
FOR EACH ROW
INSERT INTO Sync_activities (table_name,table_id,admin_id,action)
VALUES('Trans_SubCategory',New.id,New.admin_id,'update');
I add the trigger but triggers even if no change is made in table.
The thing is - you're forgetting to set proper delimiter. Your first syntax contains multiple operators inside trigger - and they need to be delimited by ; - but you're not changing global delimiter - thus, MySQL treats that as syntax end - and, therefore, that's an error (because trigger isn't completed, obviously).
Your second syntax is executed completely since it has only one operator (and that stands for trigger end as well) - you've not enclosed it by BEGIN..END
To fix the issue, just do:
DELIMITER //
CREATE TRIGGER Trans_SubCategory_update AFTER UPDATE ON Trans_SubCategory
FOR EACH ROW
BEGIN
IF NEW.ts != OLD.ts THEN
INSERT INTO Sync_activities (table_name,table_id,admin_id,action) VALUES ('Trans_SubCategory', NEW.id, NEW.admin_id,'update');
END IF;
END;//
DELIMITER ;
