如何在SQL Server SProc中设置参数？

Question

我有以下SProc，对我来说很好用，但是我试图创建两个参数，以传入两个变量，而我实际上有0个参数。

ALTER PROCEDURE [dbo].[TimeSeries]

AS
BEGIN

Drop Table UNION_SUMMARY

DECLARE @StartDate DATETIME
DECLARE @EndDate DATETIME

SELECT *
INTO  UNION_SUMMARY
FROM
(
Select AsOfDate,Portfolio,PID,Reportable_Amount,'TBL_TMP_MG_MORTGAGE_SCHED_HIST_SPLIT' AS TBL From TBL_TMP_MG_MORTGAGE_SCHED_HIST_SPLIT Where AsOfDate Between @StartDate AND @EndDate 
Union Select AsOfDate,Portfolio,PID,Reportable_Amount,'TBL_FMDDATA_HIST_SPLIT' AS TBL From TBL_FMDDATA_HIST_SPLIT Where AsOfDate Between @StartDate AND @EndDate 
Union Select AsOfDate,Portfolio,PID,Reportable_Amount,'TBL_FR2052A_CDARS_HIST_SPLIT' AS TBL From TBL_FR2052A_CDARS_HIST_SPLIT Where AsOfDate Between @StartDate AND @EndDate 
Union Select AsOfDate,Portfolio,PID,Reportable_Amount,'TBL_FR2052A_OperationalDepositTag_SPLIT' AS TBL From TBL_FR2052A_OperationalDepositTag_SPLIT Where AsOfDate Between @StartDate AND @EndDate 
Union Select AsOfDate,Portfolio,PID,Reportable_Amount,'TBL_FR2052A_FXDH_REVAL_HIST_SPLIT' AS TBL From TBL_FR2052A_FXDH_REVAL_HIST_SPLIT Where AsOfDate Between @StartDate AND @EndDate 
Union Select AsOfDate,Portfolio,PID,Reportable_Amount,'TBL_MULTI_ACCOUNT_HIST_SPLIT' AS TBL From TBL_MULTI_ACCOUNT_HIST_SPLIT Where AsOfDate Between @StartDate AND @EndDate 
Union Select AsOfDate,Portfolio,PID,Reportable_Amount,'TBL_MULTI_LD_BALANCE_HIST_SPLIT' AS TBL From TBL_MULTI_LD_BALANCE_HIST_SPLIT Where AsOfDate Between @StartDate AND @EndDate 
Union Select AsOfDate,Portfolio,PID,Reportable_Amount,'TBL_MULTI_LD_HIST_SPLIT' AS TBL From TBL_MULTI_LD_HIST_SPLIT Where AsOfDate Between @StartDate AND @EndDate 
Union Select AsOfDate,Portfolio,PID,Reportable_Amount,'TBL_FR2052A_SCHD_HIST_SPLIT' AS TBL From TBL_FR2052A_SCHD_HIST_SPLIT Where AsOfDate Between @StartDate AND @EndDate 
Union Select AsOfDate,Portfolio,PID,Reportable_Amount,'TBL_MULTI_MG_FUTURE_BALANCE_HIST_SPLIT' AS TBL From TBL_MULTI_MG_FUTURE_BALANCE_HIST_SPLIT Where AsOfDate Between @StartDate AND @EndDate 
Union Select AsOfDate,Portfolio,PID,Reportable_Amount,'TBL_MULTI_MM_HIST_SPLIT' AS TBL From TBL_MULTI_MM_HIST_SPLIT Where AsOfDate Between @StartDate AND @EndDate 
Union Select AsOfDate,Portfolio,PID,Reportable_Amount,'TBL_FR2052A_TPOS_HIST_SPLIT' AS TBL From TBL_FR2052A_TPOS_HIST_SPLIT Where AsOfDate Between @StartDate AND @EndDate 
Union Select AsOfDate,Portfolio,PID,Reportable_Amount,'TBL_FR2052A_AGG_BOC_HIST' AS TBL From TBL_FR2052A_AGG_BOC_HIST Where AsOfDate Between @StartDate AND @EndDate 
Union Select AsOfDate,Portfolio,PID,Reportable_Amount,'TBL_FR2052A_NB_IU_HIST' AS TBL From TBL_FR2052A_NB_IU_HIST Where AsOfDate Between @StartDate AND @EndDate 
) a

END

我希望在这里看到2个参数，但我看到0。

Answer 1

因为您的SP没有参数。在您的过程中，@StartDate和@EndDate是变量。

要声明参数，您需要将它们放在CREATE / ALTER子句中。例如：

ALTER PROCEDURE [dbo].[TimeSeries] @StartDate datetime, @EndDate datetime AS
BEGIN

    DROP TABLE dbo.UNION_SUMMARY;

    SELECT *
    INTO dbo.UNION_SUMMARY
    ...

END

Answer 2

syntax如下：

ALTER PROCEDURE [dbo].[TimeSeries]
     @StartDate DATETIME,
     @EndDate DATETIME
AS
BEGIN

Drop Table UNION_SUMMARY

SELECT *
INTO  UNION_SUMMARY
FROM
(
Select AsOfDate,Portfolio,PID,Reportable_Amount,'TBL_TMP_MG_MORTGAGE_SCHED_HIST_SPLIT' AS TBL From TBL_TMP_MG_MORTGAGE_SCHED_HIST_SPLIT Where AsOfDate Between @StartDate AND @EndDate 
Union Select AsOfDate,Portfolio,PID,Reportable_Amount,'TBL_FMDDATA_HIST_SPLIT' AS TBL From TBL_FMDDATA_HIST_SPLIT Where AsOfDate Between @StartDate AND @EndDate 
Union Select AsOfDate,Portfolio,PID,Reportable_Amount,'TBL_FR2052A_CDARS_HIST_SPLIT' AS TBL From TBL_FR2052A_CDARS_HIST_SPLIT Where AsOfDate Between @StartDate AND @EndDate 
Union Select AsOfDate,Portfolio,PID,Reportable_Amount,'TBL_FR2052A_OperationalDepositTag_SPLIT' AS TBL From TBL_FR2052A_OperationalDepositTag_SPLIT Where AsOfDate Between @StartDate AND @EndDate 
Union Select AsOfDate,Portfolio,PID,Reportable_Amount,'TBL_FR2052A_FXDH_REVAL_HIST_SPLIT' AS TBL From TBL_FR2052A_FXDH_REVAL_HIST_SPLIT Where AsOfDate Between @StartDate AND @EndDate 
Union Select AsOfDate,Portfolio,PID,Reportable_Amount,'TBL_MULTI_ACCOUNT_HIST_SPLIT' AS TBL From TBL_MULTI_ACCOUNT_HIST_SPLIT Where AsOfDate Between @StartDate AND @EndDate 
Union Select AsOfDate,Portfolio,PID,Reportable_Amount,'TBL_MULTI_LD_BALANCE_HIST_SPLIT' AS TBL From TBL_MULTI_LD_BALANCE_HIST_SPLIT Where AsOfDate Between @StartDate AND @EndDate 
Union Select AsOfDate,Portfolio,PID,Reportable_Amount,'TBL_MULTI_LD_HIST_SPLIT' AS TBL From TBL_MULTI_LD_HIST_SPLIT Where AsOfDate Between @StartDate AND @EndDate 
Union Select AsOfDate,Portfolio,PID,Reportable_Amount,'TBL_FR2052A_SCHD_HIST_SPLIT' AS TBL From TBL_FR2052A_SCHD_HIST_SPLIT Where AsOfDate Between @StartDate AND @EndDate 
Union Select AsOfDate,Portfolio,PID,Reportable_Amount,'TBL_MULTI_MG_FUTURE_BALANCE_HIST_SPLIT' AS TBL From TBL_MULTI_MG_FUTURE_BALANCE_HIST_SPLIT Where AsOfDate Between @StartDate AND @EndDate 
Union Select AsOfDate,Portfolio,PID,Reportable_Amount,'TBL_MULTI_MM_HIST_SPLIT' AS TBL From TBL_MULTI_MM_HIST_SPLIT Where AsOfDate Between @StartDate AND @EndDate 
Union Select AsOfDate,Portfolio,PID,Reportable_Amount,'TBL_FR2052A_TPOS_HIST_SPLIT' AS TBL From TBL_FR2052A_TPOS_HIST_SPLIT Where AsOfDate Between @StartDate AND @EndDate 
Union Select AsOfDate,Portfolio,PID,Reportable_Amount,'TBL_FR2052A_AGG_BOC_HIST' AS TBL From TBL_FR2052A_AGG_BOC_HIST Where AsOfDate Between @StartDate AND @EndDate 
Union Select AsOfDate,Portfolio,PID,Reportable_Amount,'TBL_FR2052A_NB_IU_HIST' AS TBL From TBL_FR2052A_NB_IU_HIST Where AsOfDate Between @StartDate AND @EndDate 
) a

END

您需要在proc声明中...

ALTER PROCEDURE [dbo].[TimeSeries] (@StartDate DATETIME,@EndDate DATETIME)
as...
