the error with trigger in MySQL 5.1.63-community - mysql

I write a trigger in MySQL 5.1.63-community , it's always note:#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 I run the code at navicat for mysql ,it's ok.
code here:
CREATE TRIGGER trig_sign
AFTER insert on students
for each row
Begin
INSERT INTO sign_in(num,uptime,flag,sid)
values(null,now(),false,NEW.sid);
end;

If the trigger body contains only one statement you don't need to use BEGIN and END:
CREATE TRIGGER trig_sign AFTER INSERT on students FOR EACH ROW
INSERT INTO sign_in(num,uptime,flag,sid) VALUES(null,now(),false,NEW.sid);
For multiple statement triggers you need to switch the delimiter:
DELIMITER //
CREATE TRIGGER trig_sign
AFTER INSERT on students
FOR EACH ROW
BEGIN
INSERT INTO sign_in(num,uptime,flag,sid)
VALUES(null,now(),false,NEW.sid);
-- more statements
END //
DELIMITER ;

You have to re-define delimiter like this:
delimiter ||
CREATE TRIGGER trig_sign
AFTER insert on students
for each row
Begin
INSERT INTO sign_in(num,uptime,flag,sid)
values(null,now(),false,NEW.sid);
end ||
delimiter;
Also you can see official doc about delimiter here.

everyone who have the some problem with me ,you can follow the code by Paul Spiegel .If it don't work ,I think your mysql version also don't support "delimiter ",I advise you change version.

MySql Syntax error when creating trigger to insert calculated value

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”.

Unexplainable MySQL Error #1064 for Empty String On creating After Update Trigger?

I was running MySQL with Server Version: 10.1.34-MariaDB (Distributed within XAmpp 7.2.7-0-VC15-installer) on Windows 8.1 machine, using PhpMyadmin on Google Chrome to access Mysql database and i got 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 '' at line 4
for this create trigger syntax :
DROP TRIGGER IF EXISTS Tsopd_main_AfterUpdate;
CREATE TRIGGER Tsopd_main_AfterUpdate AFTER UPDATE
ON sopd_main FOR EACH ROW
BEGIN
SET #jns = 1;
END
When i changed the code like this :
DROP TRIGGER IF EXISTS Tsopd_main_AfterUpdate;
CREATE TRIGGER Tsopd_main_AfterUpdate AFTER UPDATE
ON sopd_main FOR EACH ROW
BEGIN
END
or like this:
DROP TRIGGER IF EXISTS Tsopd_main_AfterUpdate;
CREATE TRIGGER Tsopd_main_AfterUpdate AFTER UPDATE
ON sopd_main FOR EACH ROW
BEGIN
-- SET #jns = 1;
END
it worked.
Can anybody Help me to show me what is wrong?
Thank you.
You need to use the DELIMITER directive to change the query delimiter, so you can use ; inside the trigger definition.
DELIMITER $$
DROP TRIGGER IF EXISTS Tsopd_main_AfterUpdate$$
CREATE TRIGGER Tsopd_main_AfterUpdate AFTER UPDATE
ON sopd_main FOR EACH ROW
BEGIN
SET #jns = 1;
END$$
DELIMITER ;

When Creating Trigger I got Error #1064 in Mysql 5

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 '' at line 6
My Trigger
CREATE TRIGGER `register_notification_after_register`
`AFTER INSERT ON register FOR EACH ROW BEGIN
Set #notification = CONCAT('New Member Register. Membership Code is',' ',new.membership_no,'.');
Set #notificationfor =CONCAT('New Membership');
call notification_masterAddUpdate(1,#notification,#notificationfor,new.reg_date,1);
END
try this:
DELIMITER $$
CREATE TRIGGER `register_notification_after_register`
AFTER INSERT ON register FOR EACH ROW BEGIN
Set #notification = CONCAT('New Member Register. Membership Code is',' ',new.membership_no,'.');
Set #notificationfor =CONCAT('New Membership');
call notification_masterAddUpdate(1,#notification,#notificationfor,new.reg_date,1);
END
$$ -- I am done server, end of block
DELIMITER ;
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

Can't create MySQL procedure to update table

I am trying to make a procedure to update an existing user. It receives the name of the user and then increments his points column. I have it like this:
CREATE PROCEDURE addPoints (IN nomeus varchar(20))
BEGIN
UPDATE User
SET
points=points+1
WHERE (nome=nomeus) ;
END;
However, I get 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 '' at line 8
How can I fix it?
When in doubt just go to dev.mysql they have some great documentation there.
http://dev.mysql.com/doc/refman/5.0/en/create-procedure.html
Looks like you found the answer to your own question. However, if you change any of the code in the procedure, don't forget to drop the procedure before trying to create it again.
Drop Procedure if exists addPoints;
http://dev.mysql.com/doc/refman/5.0/en/drop-procedure.html
Yeah, I had to use delimiters:
delimiter //
CREATE PROCEDURE addPoints(IN nomeuser varchar(256))
BEGIN
UPDATE User
SET
points = points + 1
WHERE nome = nomeuser;
END;//
delimiter ;

Trigger only if Table if updated

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 ;
