Question

I do a select and it brings back a list of IDs. I then want to call another procedure for each ID that calculates a result, so I end up with a list of results.

How can I do this? I need some kind of loop but I am not very good at SQL.

Edit: Microsoft SQL 2008, and purely in SQL

Answer 1

Write a user defined function that takes in the ID and returns the calculated result you can then get that result for each ID with a query like this:

SELECT id, DatabaseYouUsed.dbo.functionYouWrote(id)
FROM DatabaseYouUsed.dbo.TableWithIDs
