Trying to create a simple trigger that after a table update, it checks if a count (InvalidLogins) is over 4, and if so, sets the field 'LockedOut' to 1. Below is how I am attempting to create the trigger, this is my first trigger for MySQL though and I can't get it to work.
CREATE TRIGGER update_user_lockout after update ON members
FOR EACH ROW SET LockedOut = 1 where invalidLogins < 4
The error that MySQL returns is:
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 '.LockedOut = 1 where invalidLogins < 4' at line 2
delimiter |
CREATE TRIGGER update_user_lockout before update ON members
FOR EACH ROW
IF NEW.invalidLogins < 4 THEN
SET NEW.LockedOut = 1;
END IF;
END
|
delimiter ;
The current record can be referenced with NEW
Choose another delimiter than ;. Otherwise the trigger definition will end at the first ; which is too early
Use a before trigger to change values before updating

I am trying to add a trigger, when a table is updated (except for two columns in that table), it updates another table. The query I used is given below:
CREATE TRIGGER my_trigger
BEFORE UPDATE ON town_1a2b3c4d
BEGIN
IF NOT UPDATE (is_killed) AND NOT UPDATE (is_executed)
BEGIN
UPDATE town_details SET game_index = game_index + 1 WHERE town_id = '1a2b3c4d';
END;
END;
But it gives me 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 'BEGIN
IF NOT UPDATE (is_killed) AND NOT UPDATE (is_executed)
BEGIN...' at line 3
I'm trying to create a trigger whereby an insertion on one table updates another. This is my SQL Query:
CREATE TRIGGER makePayment AFTER INSERT ON Payments FOR EACH ROW
BEGIN
UPDATE Invoice
SET InvoiceClientPaid = SUM(InvoiceClientPaid + NEW.PaymentAmt)
WHERE InvoiceID = NEW.PaymentInvoiceID;
END;
No matter what I do I get the following error:
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 6
I don't think it's related to the SUM, because trying a basic = 1 on the SET command gives me the exact error. There is no '' at line 6 which is very confusing?
If you're entering this query directly into MySQL you will need to change the delimiter prior to the query using (e.g.) DELIMITER //, otherwise it thinks the query ends at the ; at the end of your UPDATE statement. MySQL then sees an END with nothing before it and complains about the nothing (''). So try this:
DELIMITER //
CREATE TRIGGER makePayment AFTER INSERT ON Payments FOR EACH ROW
BEGIN
UPDATE Invoice
SET InvoiceClientPaid = SUM(InvoiceClientPaid + NEW.PaymentAmt)
WHERE InvoiceID = NEW.PaymentInvoiceID;
END; //
DELIMITER ;
I just want to create a trigger for my phpmyadmin. Basically the intended function is whenever I update a credit column of my finance table, the balance column will be automatically updated for each row.
My program is:
CREATE TRIGGER UPDATE_BALANCE AFTER UPDATE financeofstudents
FOR EACH ROW
BEGIN
IF financeofstudents.credit > 0
AND
financeofstudents.credit <= financeofstudents.debit
THEN
UPDATE financeofstudents SET financeofstudents.balance = financeofstudents.debit- financeofstudents.credit;
END IF;
END
but it gives me this error:
Error
SQL query:
CREATE TRIGGER UPDATE_BALANCE AFTER UPDATE financeofstudents
FOR EACH ROW
BEGIN
IF financeofstudents.credit > 0
AND
financeofstudents.credit <= financeofstudents.debit
THEN
UPDATE financeofstudents SET financeofstudents.balance = financeofstudents.debit-financeofstudents.credit

I don't know where is the problem. Expert guys, please help me.
The error message is a useful hint here. It says .. for the right syntax to use near 'some text from your query starting with the first thing it didn't understand'.
In your case, you need the word ON before the name of the table.
CREATE TRIGGER update_balance
AFTER UPDATE
ON financeofstudents
FOR EACH ROW
If you observed that MySQL error messages are hard to interpret, you would be correct.
m writing following lines for creating a trigger:
create trigger notify after insert on applications
for each row
begin
insert into notifications SET sno=1;
end;
but everytime i get following 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 4
line 4 is - insert into notifications SET sno=1
MySQL is confused about the delimiters. It thinks the first ; is the end of the TRIGGER declaration (which it is not). Use delimiter to change it temporarily, and later to change it back:
delimiter |
create trigger notify after insert on applications
for each row
begin
insert into notifications (sno) values (1);
end;
|
delimiter ;
More in the documentation.
I am trying to set up a trigger on a table to copy the contents of a row into another table.
I have the following:
CREATE TRIGGER story_deleted BEFORE DELETE ON stories
FOR EACH ROW BEGIN
INSERT INTO stories_backup SET story_id = OLD.story_id;
END;
This returns the following error though:
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
I can't work out where I'm going wrong with this. Any ideas?
Try changing the delimiter
DELIMITER $$
CREATE TRIGGER story_deleted BEFORE DELETE ON stories
FOR EACH ROW
BEGIN
INSERT INTO stories_backup SET story_id = OLD.story_id;
END $$
DELIMITER ;
and as far as your privileges go, run this query
SHOW GRANTS;
If SUPER is not there, you could
request your DBA to add that privilege for you
have your DBA create the trigger for you
