Hi,

to my knowledge this is not possible. MySQL has no chance to enforce certain data to go into certain MyISAM tables only. Hence the MERGE table can never be sure that data with a certain key (part) can only be in a subset of the tables.

You might want to take a look at the PARTITION feature of 5.1. It can do these things.
