I have a table that contains permissions based on a group id. How would I go about building a script that would compare two groups and return only the records that do not match? Any help will be appreciated.Example:
Group ID Item Permission
123 D-Report Y
123 G-Report Y
134 D-Report Y
134 G-Report N
Output:
Group ID Item Permission
134 G-Report N
Why would you not want to return the (second) record in bold in addition to or instead of the record that is returned?
My thought question: Have you ever been told that your query runs too fast?
My advice:
INDEXing a poor-performing query is like putting sugar on cat food. Yeah, it probably tastes better but are you sure you want to eat it?
The path of least resistance can be a slippery slope. Take care that fixing your fixes of fixes doesn't snowball and end up costing you more than fixing the root cause would have in the first place.
