вы можете использовать динамический SQL, используя SP_EXECUTESQL как это -

Но прежде чем обратите внимание, что - не начинайте свое имя SP с префиксом «sp_», поскольку оно зарезервировано для системной хранимой процедуры на сервере sql.

CREATE PROCEDURE usp_hrm_Employee_Paged (
    @PageNo INT = 1 
    ,@PageSize INT = 10 
    ,@where NVARCHAR(500) 
    ) 
AS 
BEGIN /*–Declaring Local Variables corresponding to parameters for modification */ 
    DECLARE @lPageNbr INT 
     ,@lPageSize INT 
     ,@lFirstRec INT 
     ,@lLastRec INT 
     ,@lTotalRows INT 

    /*Setting Local Variables*/ 
    SET @lPageNbr = @PageNo 
    SET @lPageSize = @PageSize 
    SET @lFirstRec = (@lPageNbr - 1) * @lPageSize 
    SET @lLastRec = (@lPageNbr * @lPageSize + 1) 
    SET @lTotalRows = @lFirstRec - @lLastRec + 1; 

    DECLARE @ExequteSql NVARCHAR(MAX) 

    SET @ExequteSql = N' 
    WITH CTE_Results 
    AS (
     SELECT ROW_NUMBER() OVER (
       ORDER BY BranchId ASC 
       ) AS ROWNUM 
      ,Count(*) OVER() AS TotalCount 
      ,EmployeeId 
      ,EmployeeFirstName 
      ,EmployeeMiddleName 
      ,EmployeeLastName 
      ,EmployeeMobile 
      ,EmployeeMobile2 
      ,EmployeeEmail 
      ,EmployeeAddress 
     FROM t_hrm_employees 
     WHERE ' + @where + ' 
     ) 
    SELECT TotalCount 
     ,ROWNUM 
     ,EmployeeId 
     ,EmployeeFirstName 
     ,EmployeeMiddleName 
     ,EmployeeLastName 
     ,EmployeeMobile 
     ,EmployeeMobile2 
     ,EmployeeEmail 
     ,EmployeeAddress 
    FROM CTE_Results AS CPC 
    WHERE ROWNUM > @lFirstRec 
     AND ROWNUM < @lLastRec 
    ORDER BY ROWNUM ASC' 

    EXEC SP_EXECUTESQL @ExequteSql ,N'@lFirstRec INT, @lLastRec INT' ,@lFirstRec = @lFirstRec ,@lLastRec = @lLastRec 

END
