SQL UPDATE TOP with ORDER BY?

Question

I have a following query:

UPDATE TOP (@MaxRecords) Messages 
SET    status = \'P\' 
OUTPUT inserted.* 
FROM   Messages 
where Status = \'N\'
and InsertDate &         


        

Answer 1

You can try sub query like

  UPDATE Messages 
    SET    status = 'P' 
    WHERE MessageId IN (SELECT TOP (@MaxRecords) MessageId FROM Messages where Status = 'N' and InsertDate >= GETDATE() ORDER BY Priority)
output inserted.*
