I have a question regarding running a delete query in MS Access and the capabilities that come with it. If I have a database built with various names and their respective account numbers, and of those names, roughly 5-10 have the same generic account number ("0000" or "9999"), how would I go about flagging for these generic account numbers? Ideally I would like to be able to check for generic account numbers on a weekly or monthly basis to make sure the data stays consistent and clean.
