A family of Microsoft relational database management systems designed for ease of use.
Access does not support the Geography datatype. There are other SQL Server data types that are not or poorly supported.
The best thing is to process that data server-side, in stored procedures, and return results with simpler data types that are supported, such as text or number.
I have done this myself, where we created several sales areas and stored them as Geography data type, and wrote a stored procedure that took an address, and returned a boolean value that indicated whether the address was within any sales area or not. Access can execute the sproc (using a pass-through query) and receive the boolean value just fine.
