I'm looking for a suggestion on how to code the following situation: I have a text file that list values. I read all the records in the text file into @arrayA. Then, I run an sql query on a database. The results of that query goes into @arrayB. I want to find out what records exist in @arrayB but don't exist in @arrayA. Can suggest a good approach? Thanks.
