通Where子句作爲參數傳遞給存儲過程

我已存儲的程序分頁和我HAVA放慢參數@where我需要通過它來statment我的SP如下通Where子句作爲參數傳遞給存儲過程

Create PROCEDURE SP_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 
     ; 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 


) 

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 
END

動態SQL就是這樣。 – DarkKnight

看這個 http://stackoverflow.com/questions/31985175/how-to-execute-sub-query-in-if-exists-condition/31985628#31985628 –

感覺就像一個代碼味道，一些外部代碼必須對這個存儲過程中的查詢有深入的瞭解，以便它可以編寫一個合理的where子句來處理它。也許閱讀[T-SQL中的動態搜索條件]（http://www.sommarskog.se/dyn-search.html）。另外，作爲一個附註，避免'sp_'前綴 - 它被保留用於微軟的**系統**程序。 –

您可以使用SP_EXECUTESQL使用動態SQL像這樣 -

但之前請注意 - 不要使用「sp_」前綴開始您的SP名稱，因爲它保留用於SQL Server中的系統存儲過程。
