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.

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)
