Question

我是存储过程的菜鸟，我创建了一个存储过程，从C＃页面获取一些参数，然后将结果作为OUTPUT参数发回。

我需要做一些计算以获得结束日期，所以我最终使用了很多IF语句。但是，当我创建存储过程时，我得到的错误是我不知道如何解决，每件事情似乎都正确！。

以下是存储过程代码：

    CREATE PROCEDURE sp_RenewSubscription 
        -- Add the parameters for the stored procedure here
        @Reference nvarchar(100),
        @SubscribtionID nvarchar(100),
        @Months int,
        @Result nvarchar(200) OUTPUT
    AS

BEGIN
    -- SET NOCOUNT ON added to prevent extra result sets from
    -- interfering with SELECT statements.
    SET NOCOUNT ON;

    DECLARE @EndDate as nvarchar;
    DECLARE @MonthCounts as int;

    IF NOT EXISTS(SELECT [Reference] FROM [Norton].[dbo].[SubscriptionStatus] WHERE [Reference] = @Reference)
    SET @Result = '0: Reference ID not found'
    ELSE
    IF NOT EXISTS(SELECT [Reference] FROM [Norton].[dbo].[SubscriptionStatus] WHERE [Reference] = @Reference AND [SubscribtionID] = @SubscribtionID)
    SET @Result = '0: Subscribtion ID not found'
    ELSE
    BEGIN 
        SELECT TOP 1 @EndDate = [EndDate], @MonthCounts = [SubscriptionMonthCount] FROM [Norton].[dbo].[SubscriptionStatus] WHERE [Reference] = @Reference AND [SubscribtionID] = @SubscribtionID
        IF @EndDate = '0'
        BEGIN 
        UPDATE [Norton].[dbo].[SubscriptionStatus]
        SET [SubscriptionMonthCount] = @Months + @MonthCounts
        WHERE [Reference] = @Reference AND [SubscribtionID] = @SubscribtionID
        END
        ELSE
        BEGIN 
        UPDATE [Norton].[dbo].[SubscriptionStatus]
        SET [SubscriptionMonthCount] = @Months
        WHERE [Reference] = @Reference AND [SubscribtionID] = @SubscribtionID
        END

    SET @Result = '1: Done Successfully'
    END
GO

END
GO

这是我得到的错误：

Msg 102，Level 15，State 1，Procedure sp_RenewSubscription，Line 44
  'END'附近的语法不正确。
  消息102，级别15，状态1，行2   'END'附近的语法不正确。*

谢谢，

Answer 1

在程序结束前删除go。

即

       END 

    SET @Result = '1: Done Successfully' 
    END 
GO  --- <-- get rid of this

END

试试这个：

CREATE PROCEDURE Sp_renewsubscription 
  -- Add the parameters for the stored procedure here 
  @Reference      NVARCHAR(100), 
  @SubscribtionID NVARCHAR(100), 
  @Months         INT, 
  @Result         NVARCHAR(200) output 
AS 
  BEGIN 
      -- SET NOCOUNT ON added to prevent extra result sets from 
      -- interfering with SELECT statements. 
      SET nocount ON; 

      DECLARE @EndDate AS NVARCHAR; 
      DECLARE @MonthCounts AS INT; 

      IF NOT EXISTS(SELECT [reference] 
                    FROM   [Norton].[dbo].[subscriptionstatus] 
                    WHERE  [reference] = @Reference) 
        SET @Result = '0: Reference ID not found' 
      ELSE IF NOT EXISTS(SELECT [reference] 
                    FROM   [Norton].[dbo].[subscriptionstatus] 
                    WHERE  [reference] = @Reference 
                           AND [subscribtionid] = @SubscribtionID) 
        SET @Result = '0: Subscribtion ID not found' 
      ELSE 
        BEGIN 
            SELECT TOP 1 @EndDate = [enddate], 
                         @MonthCounts = [subscriptionmonthcount] 
            FROM   [Norton].[dbo].[subscriptionstatus] 
            WHERE  [reference] = @Reference 
                   AND [subscribtionid] = @SubscribtionID 

            IF @EndDate = '0' 
              UPDATE [Norton].[dbo].[subscriptionstatus] 
              SET    [subscriptionmonthcount] = @Months + @MonthCounts 
              WHERE  [reference] = @Reference 
                     AND [subscribtionid] = @SubscribtionID 
            ELSE 
              UPDATE [Norton].[dbo].[subscriptionstatus] 
              SET    [subscriptionmonthcount] = @Months 
              WHERE  [reference] = @Reference 
                     AND [subscribtionid] = @SubscribtionID 

            SET @Result = '1: Done Successfully' 
        END 
  END 

GO
