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

Question

我有存储过程，我在其中有一个事务。

当我与SQL Server Management Studio中执行它没有错误，但是当我用我的C＃代码执行它出现以下错误：

The ROLLBACK TRANSACTION request has no corresponding BEGIN TRANSACTION

的代码是：

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，所以在回滚的地方它不存在。切换它：BEGIN TRAN 然后 BEGIN TRY。

回滚必须在事务范围内发生，而不是在它之前或之后。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Emply shell。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 ;
