A family of Microsoft relational database management systems designed for ease of use.
That doesn't seem to work in my context. I have a query in which there is a text field called "EndOfService" (which really should be a boolean but I didn't design this) that contains the letter "x" whenever that customer is dead or something. In the query design screen, I can put an "x" in the criteria box and when run, only the records with "x" come up. What I really want is all the records that DONT have an x. If I look at the SQL, and replace the = with a <>, I get back no records.
WHERE (((tbl_Clients.[Fin de service]) ="x") AND ((tbl_Clients.NoMail)=False))
