T-Sql help needed in Sql Server 2005 - asp.net

Question

I have created one stored procedure which runs on 5000 users in tbluser table with some filter condition in database.There are 4 filtering condition(FC1,FC2,FC3,FC4).Filtering condition has some ListBox and dropdown list of department and countries.I want output as given below:
ID Name StaffNo department Points
1 KK 111 dep1 2
2 NN 222 dep2 1
3 DD 333 dep3 4
I got ID,Name,StaffNo,department in resultset but not points.
points calculation would be based on filtering condition like
if FC1 matched user gained point 1,if both FC1 and FC2 matched user gained 2 point,if both FC1 ,FC2 and FC3 matched user gained 3 point etc.
--in stored procedure i m using dynamic query
DECLARE #SQL VARCHAR(2000)
SET #SQL = 'SELECT U.UserID, U.StaffNo,U.FirstName+'' ''+ U.LastName AS EmployeeName,''?'' AS Points FROM tblUser U '
SET #SQL = #SQL+' WHERE U.Department in (' + #SqlDepartment + ') '
---------------------Update---------------------------------------
IF #SqlLanguage <> ''
SET #SQL = #SQL+' OR U.UserID IN (SELECT UserID FROM Country WHERE LCValues IN ('+ #SqlLanguage +') )'
IF #SqlAreas <> ''
SET #SQL = #SQL+' OR U.UserID IN (SELECT UserID FROM tblAreas WHERE '+#SqlAreas+')'
---------------------Update---------------------------------------
...other filtering condition
EXEC (#SQL)
all filtering condition are implemented with OR logic.

Answer 1

Have you tried implementing a CASE statement to calculate the "Points"?
--in stored procedure i m using dynamic query
DECLARE #SQL VARCHAR(2000)
SET #SQL = '
SELECT
U.[UserID],
U.[StaffNo],
U.[FirstName]+'' ''+ U.[LastName] AS EmployeeName,
(
CASE WHEN EXISTS(SELECT 1 FROM [Country] WHERE /*Your filter comes in here*/) THEN 1 ELSE 0 END +
CASE WHEN EXISTS(SELECT 1 FROM [tblAreas] WHERE /*Your filter comes in here*/) THEN 1 ELSE 0 END +
CASE WHEN EXISTS(SELECT 1 FROM [OtherTable1] WHERE /*Your filter comes in here*/) THEN 1 ELSE 0 END +
CASE WHEN EXISTS(SELECT 1 FROM [OtherTable2] WHERE /*Your filter comes in here*/) THEN 1 ELSE 0 END
) AS Points
FROM [tblUser] U'
SET #SQL = #SQL+' WHERE U.Department in (' + #SqlDepartment + ') OR'...
...other filtering condition
EXEC (#SQL)

I think you might be better off working out the points in your code rather than in the SQL
The only way I can think of doing it is with UNIONS which would be horrible

Answer 3

You can use left outer join to your filter condition, group by UserID to not get duplicates, add a value of 1 for hits and use coalesce to set 0 for no hits.
Some sample code that shows what I mean using Area and Country as filter condition.
declare #U table (UserID int, Name varchar(50), StaffNo char(3), department char(4))
declare #C table (CountryID int, UserID int)
declare #A table (AreaID int, UserID int)
insert into #U values (1, 'KK', '111', 'dep1')
insert into #U values (2, 'NN', '222', 'dep2')
insert into #U values (3, 'DD', '333', 'dep3')
insert into #C values(1, 1)
insert into #C values(2, 1)
insert into #C values(3, 2)
insert into #C values(3, 3)
insert into #A values(1, 1)
insert into #A values(2, 1)
insert into #A values(3, 2)
select
U.UserID,
U.Name,
U.StaffNo,
U.department,
coalesce(C.Point, 0)+coalesce(A.Point,0) as Points
from #U as U
left outer join
(select UserID, 1 as Point
from #C
-- where ...?
group by UserID) as C
on U.UserID = C.UserID
left outer join
(select UserID, 1 as Point
from #A
-- where ...?
group by UserID) as A
on U.UserID = A.UserID
