We have a database created in SQL. We link tables into Access for users to input data. There is a new field added<br>and in Access it should be "yes/no" data type. I am not sure which data type I should put in SQL (don't see yes/no); for now I put in "Binary". <br><br>However, in Access, I couldn't change it to yes/no to get the check box. And I am trying to put in something(0 or1) in that field in SQL, it says "can't edit this cell". <br><br>What should I do? <br><br>Advice needed - I want to take "database design" class (not necessary Access or certain db, just fundamental). I am in<br>Washington, DC metro area (MD, NorthernVA). Any good training vendors for that? <br><br>Thanks.
