Trying to create a daily event in mysql:
CREATE EVENT ResetStatus
ON SCHEDULE
EVERY 1 DAY
DO
BEGIN
IF (DATE('2013-04-05') = CURDATE()) THEN
UPDATE mytable
SET resetstatus = 1
WHERE id = (SELECT pid FROM usertable WHERE priority = 'A');
END IF;
END;
Get an error:
Lookup Error - MySQL Database 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 12
If i take the update statement and place in TOAD and run, it runs with no errors.
As documented under Defining Stored Programs:
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.
You need to set your client to use a statement delimiter other than ;, as it currently thinks that the first semicolon that it encounters (at the end of the UPDATE statement) is terminating the CREATE EVENT statement.
In the MySQL command line client, one can use the DELIMITER command:
DELIMITER ;; -- or anything else you like
CREATE EVENT ResetStatus
ON SCHEDULE
EVERY 1 DAY
DO
BEGIN
IF (DATE('2013-04-05') = CURDATE()) THEN
UPDATE mytable
SET resetstatus = 1
WHERE id = (SELECT pid FROM usertable WHERE priority = 'A');
END IF;
END
;;
DELIMITER ; -- return to normal

Here is my trigger, I am getting the MySQL syntax error. I wanted to reduce the balance from sms_index table sms_count column value.
CREATE TRIGGER sms_log_update AFTER UPDATE ON sms_index
FOR EACH ROW
BEGIN
IF NEW.approved_status = '1' THEN
UPDATE sms_package SET balance = (balance - OLD.sms_count) WHERE group_id = OLD.ins_group_id;
END IF;
END;
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
Your code looks correct, except for the possible problem of the delimiter. Try the following:
DELIMITER //
CREATE TRIGGER sms_log_update AFTER UPDATE ON sms_index
FOR EACH ROW
BEGIN
IF NEW.approved_status = '1' THEN
UPDATE sms_package SET balance = (balance - OLD.sms_count)
WHERE group_id = OLD.ins_group_id;
END IF;
END;//
DELIMITER ;
From the documentation:
However, just as for stored routines, if you use the mysql program to define a trigger that executes multiple statements, it is necessary to redefine the mysql statement delimiter so that you can use the ; statement delimiter within the trigger definition.
I'm writing a trigger in MySQL to take log of table updates. The log table is called individuo_storico and the target table is called individuo. When individuo is updated, I want to check if IDQualifica and IDLivello are changed, if yes a record in individuo_storico is inserted.
I write down this code but I get a #1064 error, where's the syntax error?
use ore;
create trigger individuo_update after update on individuo
for each row
begin
if ( NEW.IDLivello <> OLD.IDLivello or NEW.IDQualifica <> OLD.IDQualifica) then
insert into individuo_storico(IDIndividuo, IDQualifica, IDLivello)
values (NEW.IDIndividuo, NEW.IDQualifica, NEW.IDLivello);
end if;
end;
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
Please wrap your trigger creation with the monikers necessary so the db engine does not choke on it. So three areas:
1) line 1
2) right after the end;
3) and then a reset to a default delimiter.
Same concept is typical with stored proc creations.
DELIMITER $$
create trigger individuo_update after update on individuo
for each row
begin
if ( NEW.IDLivello <> OLD.IDLivello or NEW.IDQualifica <> OLD.IDQualifica) then
insert into individuo_storico(IDIndividuo, IDQualifica, IDLivello)
values (NEW.IDIndividuo, NEW.IDQualifica, NEW.IDLivello);
end if;
end;$$
DELIMITER ;
I get this error on my PHPMyAdmin
#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 3
[EDIT]
Sorry, I didn't put the full thing before, i've already had an BEGIN and an END, Look.
CREATE TRIGGER `accounts_insert` BEFORE INSERT ON `accounts`
FOR EACH ROW BEGIN
SET new.RegiDate = now();
SET new.UpdateDate = now();
END;
This is the line ^^
If your trigger is only one instruction, you don't need the begin keyword:
create trigger `accounts_insert` before insert on `accounts`
for each row
set new.RegiDate = now();
If your trigger has multiple instructions, then you need to:
Change the default delimiter
Enclose the trigger instructions in a begin...end block
Restore the default delimiter
Example:
delimiter $$
create trigger `accounts_insert_2` before insert on `accounts`
for each row
begin
set new.RegiDate = now();
set #newRows = coalesce(#newRows, 0) + 1; -- Just a dummy example
end; &&
delimiter ;
Why the delimiter $$ and delimiter ; are important?
When you write a query, MySQL assumes that it ends where it finds the first standard "instruction terminator" (;). Since your trigger has more than one instruction, and every instruction must end with ;, then MySQL assumes that the trigger definition is ended, and (of course) fails to execute it. So, what can be done? Simply redefine temporally the standard instruction terminator:
delimiter $$
Now, each instruction must end with $$ to be executed. Define your trigger, and, when you want to end the definition, use your new temporary instruction terminator $$, and then redefine the terminator to the normal ;:
delimiter ;
This must be done every time you define a multi insstruction trigger or a stored procedure or function.
I need to create a trigger in my database.
The trigger must be able to analyse event before insert. In case of the last event already existing in the database has the same status, the trigger has to cancel the insert and update the last event.
I tried to create one but I can't add it in my database because of mysql errors:
#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
Here the trigger:
CREATE TRIGGER events_before_insert
BEFORE INSERT ON monitoringV2.events
FOR EACH ROW
BEGIN
DECLARE id_last_event;
DECLARE status_last_event;
SELECT id INTO id_last_event, status INTO status_last_event FROM events WHERE module_id=NEW.module_id ORDER BY serverDate DESC LIMIT 1;
IF NEW.status = status_last_event THEN
UPDATE events SET serverDate=NOW() WHERE id=id_last_event;
signal sqlstate '00000' set message_text = "Update instead of insert";
END IF;
END;
Here are information server:

Apache 2.4.2 VC9
MySQL 5.5.27

You will need to delimit your create statement:
delimiter //
CREATE...
...
END;
//
DELIMITER ;
and you will probably need to define a type for each variable declared, e.g.
DECLARE x INT;
You have to change DELIMITER before creating a trigger like this
DELIMITER $$
CREATE TRIGGER...
...
END;
$$
DELIMITER ;
You might not need to implement a trigger for this. The operation you are describing is formally known as UPSERT, i.e. update or insert.
This is how it's done in MySQL and you could also look at REPLACE.
Here is another question covering this.
I have about 2 years of mySQL under my belt but am diving into stored procedures for the first time to create an internal analytic tool for my site. I am usually good at tracking down SQL errors but this one is eluding me.
The error I get is this :
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 3
This is the code I execute to receive this error:
CREATE PROCEDURE STORE_ANALYTICS (IN chain VARCHAR(300))
BEGIN
UPDATE _analytics_clicks
SET chainCount = (chainCount + 1)
WHERE visitChain = chain;
IF SELECT ROW_COUNT() = 0 THEN
INSERT INTO _analytics_clicks (visitChain, chainCount)
VALUES (chain, 1);
END IF;
END|
It is worth noting that before I execute this, I executed
DELIMITER |
The structure of the table I am trying to alter is this:
chainID int(11) auto_increment
visitChain varchar(300)
chainCount int(11)
When I execute line 3 by itself, replacing visitChain=chain with visitChain='0' (0 is a test chain i enetered), the command runs fine and chainCount is incremented.
Any ideas on why I am getting this error/the stored procedure is not being created?
Thanks,
Matt
EDIT :
Included delimiter in SQL command:
DELIMITER |
CREATE PROCEDURE STORE_ANALYTICS (IN chain VARCHAR(300))
BEGIN
UPDATE _analytics_clicks SET chainCount = (chainCount+1) WHERE visitChain=chain;
IF ROW_COUNT() = 0 THEN
INSERT INTO _analytics_clicks (visitChain, chainCount) VALUES (chain, 1);
END IF;
END|
DELIMITER ;
Gave me this error:
Fatal error: Maximum execution time of 300 seconds exceeded in C:\wamp\apps\phpmyadmin3.2.0.1\libraries\import\sql.php on line 119
You can do
IF ROW_COUNT() = 0 THEN
rather than IF SELECT ROW_COUNT() = 0 THEN. No need for the SELECT.
I suspect that your delimiter is not being set properly.
I usually include the delimiter set/unset statements with my SQL source, that way "it just runs" - it's good practice that every SQL file can run stand-alone eg:
delimiter ~
create procedure ...
end;~
delimiter ;
Try changing your delimiter to something less deadly than a pipe char - try my tilda ~ char, which never gives me any trouble. I've seen $$ used often as well.
