So I have this data
+----+----------+-------+---------------+----------------+------------+--------+
| id | date | accid | accid_currbal | Action | Desc | Amount |
| 1 | 05/06/17 | 1 | 7777 | Create Account | some desc… | 7777 |
| 2 | 05/06/17 | 1 | 32091 | Add Funds | some desc… | 24324 |
| 3 | 05/06/17 | 1 | 32100 | Add Funds | some desc… | 9 |
| 4 | 05/06/17 | 1 | 32600 | Add Funds | some desc… | 500 |
+----+----------+-------+---------------+----------------+------------+--------+
And an BEFORE_UPDATE trigger that accesses this table when it fires
CREATE ..... TRIGGER
`db_moneytracker`.`transactions_BEFORE_UPDATE` BEFORE UPDATE ON
`transactions` FOR EACH ROW
BEGIN
DECLARE adj INT;
if (old.amount <> new.amount && old.accid = new.accid) then
set adj = new.amount - old.amount;
update transactions set accid_curr_accbalance = accid_curr_accbalance + adj
where accid = new.accid and `date` >= new.date;
elseif (old.accid <> new.accid) then
SIGNAL SQLSTATE '45000'
SET MESSAGE_TEXT = 'IDs unchangeable';
end if;
END
But produces an error when updated
1442: Can't update table 'transactions' in stored function/trigger because
it is already used by statement which invoked this stored function/trigger.
I think I understood what it meant so... I want the trigger not to fire the UPDATE is fired by THIS trigger.
