Question : How to deal with binary data types in access

Hi,

I have two tables in two databases that I have linked with my access database.
Table A - in Database A has a primary id in binary (e.g. 0x0002a000084749a4)
Table B - in Database B has an id table that links table A to B, but the hex is stored as varchar.

When I link the tables into access, Table A's id has data type - binary and doesn't show anything, and Table B's id has data type - text and shows the text string of the hex.

I need a way to compare these two tables, so I need a way to get the two ids to link to eachother.  Any way to do this?

Also, if i implicitly do a query:
SELECT *
From A
WHERE A.id = 0x0002a000084749a4

i get results. but i would need to do a comparsion of the two tables:

e.g. I need to look for all securities in both table A and B, or only in A, but not in B
SELECT *
FROM A, B
WHERE A.id = B.id

If table B contains "0002a000084749a4" (as string) in field "ID", try this expression:

    BinValue: Eval('0x'+ID)

You can then link your table A to the query.
