Question

I have two tables one called fs_note the other called dumy_fs_note

I created after Insert and after Delete triggers on the fs_table that insert a row with calculated data to the dumy_fs_table that has an after insert trigger that should update a certain row in fs_table with the new values
The problem is that now i am having error:
#1442 Can't update table 'fs_note' in stored function/trigger because it is already used by statement which invoked this stored function/trigger.
why is that?? it is the dumy_fs_note table that is trying to update the fs_table not the same table, Any idea what’s wrong?
Thanks in advance

Yeah, you just can’t do that. Mysql is this way preventing circular loops and memory issues… It is like updating a cursor being parsed: some engines allow it, others no.
