Question

我有存储过程，我有一个交易。

当我使用SQL Server管理工作室执行它时没有错误，但是当我使用我的C＃代码执行它时，会发生以下错误：

ROLLBACK TRANSACTION请求没有相应的BEGIN TRANSACTION

代码是：

CREATE PROCEDURE [dbo].[AddHardDisk]
    @name nvarchar(50), @brand nvarchar(50), @serial nvarchar(50), @cost float,  @seller nvarchar(50),@note nvarchar(1000),@buyDate Date,
    @size int ,@moneyType nvarchar(50)

AS

    DECLARE  @addedDeviceID int

 BEGIN TRY
    BEGIN  TRAN   

        insert into Product(Name,Brand,Serial,Cost,Seller,Note,MoneyType,BuyDate)
        values(@name,@brand,@serial,@cost,@seller,@note,@moneyType,@buyDate)

        select @addedDeviceID =SCOPE_IDENTITY()

        insert into HardDisk(ID,size)
        values(@addedDeviceID,@size) 

        exec DecreaseMoneyFromFund @moneyType,@cost         

    COMMIT           
END TRY
BEGIN CATCH

    IF @@TRANCOUNT > 0
        ROLLBACK
END CATCH

Answer 1

TRAN的范围是你的TRY块，所以在你回滚的catch中它不存在。切换它：BEGIN TRAN 然后开始尝试。

回滚必须在事务范围内发生，而不是在事务之前或之后。修改后的代码：

CREATE PROCEDURE [dbo].[AddHardDisk]
    @name nvarchar(50), @brand nvarchar(50), @serial nvarchar(50), @cost float,  @seller nvarchar(50),@note nvarchar(1000),@buyDate Date,
    @size int ,@moneyType nvarchar(50)

AS

    DECLARE  @addedDeviceID int

 BEGIN TRAN
    BEGIN  TRY   

        insert into Product(Name,Brand,Serial,Cost,Seller,Note,MoneyType,BuyDate)
        values(@name,@brand,@serial,@cost,@seller,@note,@moneyType,@buyDate)

        select @addedDeviceID =SCOPE_IDENTITY()

        insert into HardDisk(ID,size)
        values(@addedDeviceID,@size) 

        exec DecreaseMoneyFromFund @moneyType,@cost         

        COMMIT           
    END TRY
    BEGIN CATCH
        IF @@TRANCOUNT > 0
            ROLLBACK
    END CATCH
END TRAN

这是我用于Sp的空壳。我想你可能会错过'Commit Tran'

 BEGIN TRY ;
  BEGIN TRAN;
        BEGIN          

 --Insert SQL Here
        END
IF @@TRANCOUNT > 0  
COMMIT TRAN ;     
END TRY

BEGIN CATCH ;
  DECLARE @ERROR_MESSAGE  VARCHAR(200) ; 
  DECLARE @ERROR_SEVERITY  INT ;
  DECLARE @ERROR_STATE  INT ;

  SET @ERROR_MESSAGE = ERROR_MESSAGE() ;
  SET @ERROR_SEVERITY = ERROR_SEVERITY() ;
  SET @ERROR_STATE = ERROR_STATE() ;

  RAISERROR ( @ERROR_MESSAGE, -- Message text.
                    @ERROR_SEVERITY , -- Severity.
                    @ERROR_STATE -- State.
                 );

Select @ERROR_MESSAGE

IF @@TRANCOUNT > 0
        ROLLBACK TRAN ;

END CATCH ;

错误：ROLLBACK TRANSACTION请求没有相应的BEGIN TRANSACTION
