Triggers "instead of" for View with "joins"

[pak attack]

Sorry for the next message, but my problem was with Oracle -> MySQL and wasn't SQL server to MYSQL:

Hi! I'm trying to insert into view but this view is made of "join":

return the error:
"Cannot insert into join view 'v12.vista1' without fields list"

The solution for this problems is using trigger "INSTEAD OF" but in MySQL doesn't appear this type of TRIGGER.
What's the real solution ?
I forced to use views.

Thanks.
