When I read the code, I thought it was a pity that Active wasn't in the DB so you could restrict the number of lines based on Active. Then I thought, don't even run the logic if Active isn't true. As I continued reading, I realized the real condition. Did you drop the Active check in the code along with modifying the select? If it's still a large # of rows being read, you might want to include your condition checks in the selection criteria. Also, hopefully, you are really running a sproc to get your data. Here's an example of using 4 condition checks with very different selection criteria. If two condition checks overlap then the data produced would overlap. The table had 5K rows in it, the selection had 39 rows in it.
declare @tbl table (Cond int, sTotID int, stot1 int, stot2 int, stot3 int)
insert into @tbl
values (1,-1, 20, -1, 49), (2, 203148, -1, -1, -1), (3, -1, 15, 29, -1), (4, -1, 25, 32, -1)
SELECT TOP 1000 Cond, TotID
,NumbRecs
,tot1
,tot2
,tot3
FROM dbo.ThreeNumberSum
JOIN @tbl on (sTotID = -1 or sTotID = TotID) AND (stot1 = -1 OR stot1 = tot1)
AND (stot2 = -1 OR stot2 = tot2) AND (stot3 = -1 OR stot3 = tot3)
Your code could just check 1 value to match all the multiple conditions. Here is an extract of all the rows:
