*That sounds like they will be merged ! . . They are to remain
separate and the "B" file is to be used for a mailing thing after it

and what fields/columns to use ! !
You need to be more specific in your description. You began with
two databases that you want to check for duplicates. It has now become
clear that you are working with two tables. And then you mentioned
fields. What fields exist in these two tables? What determines whether a
row in the "B" table is a duplicate based upon what is contained in
table "A"?
The simple answer to your question: the same way that you would do
it by hand. The only problem with this answer is that it does not
include any specifics.
If you would write down how you would do this by hand step by
step, then we would know what has to be done step by step, and we could
suggest how to do each step. You might even see how to do it by yourself.

*How do I check for duplicates in a data base using another data
base ?

SELECT "A".* FROM "A" JOIN "B" ON "A"."ID" = "B"."ID"
returns all rows from table A with an equivalent ID in table B.
