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

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.
I have a table named sample_table and its columns are col_a, col_b, col_c.
I am trying to create a trigger in MySQL 5.6 which will update col_c(as concat(col_a,col_b)) on insertion of a row. Query which I have written for this is:
create trigger trg_sample_table
after insert on sample_table
for each row
begin
set col_c=concat(col_a,col_b)
end;
While running this sql, the error I am getting is:
ERROR 1064 (42000): 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' at line 6.
Could any one of you please help me to create a trigger as I need?
You need to make it a before insert. Try this:
create trigger trg_sample_table before insert on sample_table for each row
begin
set new.col_c=concat(new.col_a,new.col_b);
end;
You cannot modify the row that you just inserted in an after insert trigger. If you want to modify it, it needs to be done in a before insert.
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
