Question

I know this has probably been asked 100 times, but I don’t know the terminology to search for:
Please tell me how I can “select Top 5”, or an equivalent, by combining a sum from 2 tables?

I need the top 5 results for “Money”, where the “Money” is the combined sum of “Money” from the table named “wallet” and “Money” from the table named “bank”, in this example.

Thanks a lot 🙂
