无法使用存储过程插入数据。 （0行）受影响）有一些错误

Question

CREATE PROCEDURE sp_BOOKEDVEHICLES
 @flag bit output,-- return 0 for fail,1 for success
 @REGISTRATIONID varchar(30),
 @VEHICLEID varchar(9),
 @VEHICLENAME varchar(20)
 AS
 BEGIN
  BEGIN TRANSACTION 
  BEGIN TRY 
 Insert into BST_TVL_BOOKED_VEHICLES_TB(REGISTRATIONID, VEHICLEID, VEHICLENAME) Values(@REGISTRATIONID,@VEHICLEID,@VEHICLENAME)
  set @flag=1;
 IF @@TRANCOUNT > 0
  BEGIN commit TRANSACTION;
  END
  END TRY 
 BEGIN CATCH
 IF @@TRANCOUNT > 0
  BEGIN rollback TRANSACTION;
  END
  set @flag=0;
  END CATCH
END
GO

Declare @flag bit
 EXEC sp_BOOKEDVEHICLES @flag output, 
 @REGISTRATIONID = '2364', 
 @VEHICLEID = '27',
 @VEHICLENAME = 'Ford'

 if @flag=1
  print 'Successfully inserted'
 else
  print 'There is some error' 

显然，代码中有错误，但我找不到它...无法使用stord程序插入数据。
它向我显示了这个错误：（0行受影响）有一些错误。

Answer 1

Insert into BST_TVL_BOOKED_VEHICLES_TB(REGISTRATIONID, VEHICLEID, VEHICLENAME) Values(@REGISTRATIONID,@VEHICLEID,@VEHICLENAME)
  set @flag=1;
 IF @@TRANCOUNT > 0
  BEGIN commit TRANSACTION;
  END

这必须抛出SQL异常，因为@flag <> 1。试试print ERROR_MESSAGE()以获得实际错误的描述？

Answer 2

好的，你正在混淆一些概念。

1 - 当您希望多个语句提交或回滚时使用事务。

例如，从客户帐户和信用卡供应商处扣款。提交或回滚。

2 - 由于您没有这个条件，只需用TRY / CATCH包装插入。

请参阅我的博客，了解错误处理的方法。

3 - 程序可以返回一个值。为什么不是零，如果好，一个如果坏。

我重写了你的代码如下。

CREATE PROCEDURE sp_BOOKEDVEHICLES
   @REGISTRATIONID varchar(30),
   @VEHICLEID varchar(9),
   @VEHICLENAME varchar(20)
AS
BEGIN
  -- TRY TO ADD A RECORD
  BEGIN TRY
    INSERT INTO BST_TVL_BOOKED_VEHICLES_TB 
      (REGISTRATIONID, VEHICLEID, VEHICLENAME) 
    VALUES 
      (@REGISTRATIONID, @VEHICLEID, @VEHICLENAME);
    RETURN 0;
  END TRY 

 -- CATCH ERROR
 BEGIN CATCH
   SELECT
        ERROR_NUMBER() AS ErrorNumber
       ,ERROR_SEVERITY() AS ErrorSeverity
       ,ERROR_STATE() AS ErrorState
       ,ERROR_PROCEDURE() AS ErrorProcedure
       ,ERROR_LINE() AS ErrorLine
       ,ERROR_MESSAGE() AS ErrorMessage;
   RETURN 1;
 END CATCH
END
GO

-- Sample call
DECLARE @RETCODE INT
 EXEC @RETCODE = sp_BOOKEDVEHICLES 
   @REGISTRATIONID = '2364', 
   @VEHICLEID = '27',
   @VEHICLENAME = 'Ford';

-- Just show the result.
IF @RETCODE = 1 
  PRINT 'BAD INSERT CALL'
ELSE
  PRINT 'GOOD INSERT CALL';

请测试代码，因为我没有定义您的表格...
