Thread: implied rows when a rule gets executed.

In a rule... is there some way of getting the number of rows updated by the 
query that activates this rule ??

... but, how can i know "condition_delete" ???

If there is no way ... i will try with triggers ... but i think it's little 
simetrical .....  ==> i can get done my stuff with rules when inserting, but 
it isn't possible when deleting ???

Thanks .....
