Nullable bool fields in MS Access linked tables

Question

Looks like I\'m not the only one out there with this issue, but there doesn\'t seem to be an anwwer to this problem.

I\'m working in Access 2010, using a linked tabl

Answer 1

I experienced the same problem in my project, where I implement some add-ons in our old ordering system from early 2000's, and boolean is widely used.

Today I found a solution by using a passthrough query as follows:

SELECT 
    *,  
    CASE MYFIELD 
       WHEN NULL THEN NULL 
       WHEN 1 THEN 1 
       WHEN 0 THEN 0 
    END AS MYRESULT
FROM 
    DBO.MYTABLE

This is not updateable but anyway regular SQL statements work there.
