Question

I usually use COUNT within a subquery to grab the desired number, but in this case I need a little help as the query contains too many arguments.

SELECT a.[QueueID]
  ,a.[CouponID]
  ,a.[ListingID]
  ,a.[User_ID]
  ,b.[CouponID]
  ,b.[ListingID]
  ,b.[CouponActive] 
  ,b.[CouponExpire] 
  ,b.[IsDeleted]
  ,c.[ListingID]
  ,c.[TypeID]
  ,c.[LevelID]
  ,@passedUserID as User_ID

FROM CouponQueue a
JOIN Coupon b
    on a.CouponID = b.CouponID
JOIN Listing c
    on b.ListingID = c.ListingID

WHERE (a.[User_ID] = @passedUserID)
AND (b.[CouponActive] = 1)
AND (b.[IsDeleted] = 0)
AND (b.[CouponExpire] > DATEADD(dd, -1, GETDATE()) OR b.[CouponExpire] IS NULL)

So lets say this query returns a result of 7 rows. All I need is this number for my VIEW. So I want to limit the ultimate result to a single row so that in the end I get:

[TotalCount] <-- Field name
[7] <-- Result

But not 7 rows of data.. I just need the count from the above query. Still plugging away and trying to learn. I looked at a few other examples but I haven’t found one with all the conditions… which is what’s messing me up. Please help!

Thank you so much!

Would this work for you?

select count(*) as TotalCOunt from (
SELECT a.[QueueID] /* 
  ,a.[CouponID]
  ,a.[ListingID]
  ,a.[User_ID]
  ,b.[CouponID]
  ,b.[ListingID]
  ,b.[CouponActive] 
  ,b.[CouponExpire] 
  ,b.[IsDeleted]
  ,c.[ListingID]
  ,c.[TypeID]
  ,c.[LevelID]
  ,@passedUserID as User_ID */

FROM CouponQueue a
JOIN Coupon b
    on a.CouponID = b.CouponID
JOIN Listing c
    on b.ListingID = c.ListingID

WHERE (a.[User_ID] = @passedUserID)
AND (b.[CouponActive] = 1)
AND (b.[IsDeleted] = 0)
AND (b.[CouponExpire] > DATEADD(dd, -1, GETDATE()) OR b.[CouponExpire] IS NULL)
) t

You can remove the columns for the count. They are not actually necessary.
