Question

Suppose I want to update two columns in one ON DUPLICATE STATEMENT:

 INSERT INTO `daily_lead_rollups` (`year`, `month`, `day`, `a_id`, `f_id`, `0_d`,`0_r`) VALUES (NEW.year,NEW.month,NEW.day,NEW.a_id,NEW.f_id, 1,NEW.payout) ON DUPLICATE KEY UPDATE    0_d  =  0_d + 1,   0_r  =0_r + NEW.payout; 

Error:

1235 – This version of MySQL doesn’t yet support ‘multiple triggers with the same action time and event for one table’

I know you can insert multiple rows, but I didn’t find anything about updating multiple columns with a calculation.

MySQL is fine with one calculation, even without

VALUES

, but has an issue with two!

I corrected the statement for future reference, the issue is resolved.

Answer 1

I’m not quite sure why you are trying to VALUES like that, but I suspect you mean this:

ON DUPLICATE KEY UPDATE 
    0_d = 0_d + 1,
    0_r = 0_r + NEW.payout

There are also some good examples of how to use ON DUPLICATE KEY UPDATE in the manual.
