Select * from (
Select  ROW_NUMBER() OVER(ORDER BY EmpID DESC) as RowNo,
    Emp.EMPID, EMP.FirstName
    From Emp
Union
Select ROW_NUMBER() OVER(ORDER BY EMPID DESC) as RowNo,
    Emp.EMPID, EMP.FirstName
    From Emp Inner Join EMPDetail On Emp.EmpID = EMPDetail.EMPID 
    Where EMPDetail.IsActive=True
    ) as _EmpTable where RowNo between 1 and 20

Hi Savalia,

This script will show error message
Ambiguous column name 'EMPID'.

I have corrected your script

SQL

SELECT * FROM (
	SELECT  ROW_NUMBER() OVER(ORDER BY EmpID DESC) as RowNo,Emp.EMPID, EMP.FirstName
	From Emp
UNION
	SELECT ROW_NUMBER() OVER(ORDER BY Emp.EMPID DESC) as RowNo,Emp.EMPID, EMP.FirstName
	FROM Emp Inner Join EMPDetail On Emp.EmpID = EMPDetail.EMPID 
	WHERE EMPDetail.IsActive=True
			) 
AS _EmpTable WHERE RowNo between 1 and 20

this way,

SQL

Select * from
(
    Select 
    ROW_NUMBER() OVER(ORDER BY EmpID DESC) as RowNo,
    Emp.EMPID, 
    EMP.FirstName
    from 
    (
            Select Emp.EMPID, EMP.FirstName
            From Emp
            Union
            Select Emp.EMPID, EMP.FirstName
            From Emp 
            Inner Join EMPDetail On Emp.EmpID = EMPDetail.EMPID
            Where EMPDetail.IsActive=True
    ) as _EmpTable 
) as a where RowNo between 1 and 20

Happy Coding!
