Do it in an app language or as a PREPARED statement in an sproc.

Hello,
Let's suppose I have 5 database: db1, db2, db3, db4, and db5. They all
have the same structure but different data.
I would like perform this select
SELECT TaskDoneOn, TaskDoneBy
FROM {database}
WHERE TaskDoneOn IS NOT NULL
and collect the data from all 5 database. However, I would like to
avoid doing something like this:
SELECT TaskDoneOn, TaskDoneBy
FROM db1
WHERE TaskDoneOn IS NOT NULL
UNION
SELECT TaskDoneOn, TaskDoneBy
FROM db2
WHERE TaskDoneOn IS NOT NULL
UNION
SELECT TaskDoneOn, TaskDoneBy
FROM db3
WHERE TaskDoneOn IS NOT NULL
UNION
SELECT TaskDoneOn, TaskDoneBy
FROM db4
WHERE TaskDoneOn IS NOT NULL
UNION
SELECT TaskDoneOn, TaskDoneBy
FROM db5
WHERE TaskDoneOn IS NOT NULL
Today I have 5, but tomorrow I can have 50 and I don't want to forget
any database.
Thanks for any help.
Andre
