This isn't "natively" supported. You can hack it with replication to a table that has a trigger, which will then insert all but one column into another table, which you can replicate on to the final destination. But I'm scared of such hacks for anything that matters :-) -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
