Question

I am using SQL Server 2008

I have a table named MYTABLE with two columns: ID, STATUS

I want to write a stored procedure that returns the records whose STATUS is 0. But this stored proc must update the STATUS of returned rows to 1. How can I do this selecting and updating operation in a single query?

Answer 1

update MyTable
set Status = 1
output inserted.*
where Status = 0

If you want to return what the table looked like before the update you should use deleted.* instead.

update MyTable
set Status = 1
output deleted.*
where Status = 0

You can of course use both if you like and you don’t have to use *. You can specify the columns you are interested in.

update MyTable
set Status = 1
output inserted.ID, inserted.status, deleted.status as OldStatus
where Status = 0
