Question

I have this query:

SELECT 
    [Address]=e.Address, 
    [LastEmail] = 
    (
        SELECT TOP 1 [Email] 
        FROM Email innerE 
        WHERE e.UserID = innerE.UserID 
        AND innerE.Contact = @emailId
        AND (IsSent is null OR isSent = 0)
        ORDER BY Timestamp DESC
    )

FROM Emails e

This works fine, but now, I realized i’d like to get the entire row containing that lastemail column, if this is possible, any ideas on how it could be done?

Answer 1

You can do this:

;WITH LastEmails
AS
(
   SELECT *, 
     ROW_NUMBER() OVER(ORDER BY Timestamp DESC) rownum
   FROM Emails
   WHERE Contact = @emailId
     AND (IsSent is null OR isSent = 0)
)
SELECT * FROM LastEmails
WHERE rownum = 1;
