Question

I need to update my column with trigger automaticly.

Here is code:

create trigger sum update on `cash`
for each row
begin
UPDATE `cash`
SET `sum_cash` = `cash` + `sum_cash`;
end;
$$

And I got following 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 'update on `cash` for each row begin UPDATE cash` SE' at line 1

I work on MySQL.

Answer 1

Try this:

delimiter $$
create trigger my_sum after update on `cash`
for each row
begin
UPDATE `cash`
SET `sum_cash` = `cash` + `sum_cash`;
end;
$$

You missed the after or before keyword. Also I changed trigger name since sum is a keyword.
