Sqlserver 和.net中的事务

sqlserver 存储过程中结合事务的代码实例

--本人多采用方式二：

--方式一
if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[USP_ProcedureWithTransaction_Demo]') and OBJECTPROPERTY(id,N'IsProcedure') = 1)
drop procedure [dbo].[USP_ProcedureWithTransaction_Demo]
GO

Create PROCEDURE [dbo].[USP_ProcedureWithTransaction_Demo]
As
Begin
SET XACT_ABORT ON
Begin Transaction
Insert Into Lock(LockTypeID) Values('A')--此语句将出错，LockTypeID为Int类型
Update Lock Set LockTypeID = 2 Where LockID = 32
Commit Transaction
SET XACT_ABORT OFF
End
GO

--方式二
if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[USP_ProcedureWithTransaction_Demo]') and OBJECTPROPERTY(id,N'IsProcedure') = 1)
drop procedure [dbo].[USP_ProcedureWithTransaction_Demo]

Insert Into Lock(LockTypeID) Values('A')--此语句将出错，LockTypeID为Int类型
Update Lock Set LockTypeID = 1 Where LockID = 32
Commit Transaction
If(@@ERROR <> 0)
Rollback Transaction
End
GO

--方式三
if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[USP_ProcedureWithTransaction_Demo]') and OBJECTPROPERTY(id,N'IsProcedure') = 1)
drop procedure [dbo].[USP_ProcedureWithTransaction_Demo]

Create PROCEDURE [dbo].[USP_ProcedureWithTransaction_Demo]
As
Begin
Begin Try
Begin Transaction
Update Lock Set LockTypeID = 1 Where LockID = 32--此语句将出错，LockTypeID为Int类型
Insert Into Lock(LockTypeID) Values('A')
Commit Transaction
End Try
Begin Catch
Rollback Transaction
End Catch
End
GO

2，.Net中使用事务处理
sqlConnection myConnection = new sqlConnection("Data Source=localhost;Initial Catalog=northwind;Integrated Security=sspI;");
myConnection.open();

sqlTransaction myTrans = myConnection.BeginTransaction(); //使用New新生成一个事务
sqlCommand myCommand = new sqlCommand();
myCommand.Transaction = myTrans;

try { myCommand.CommandText = "Update Address set location='23 rain street' where userid='0001'"; myCommand.ExecuteNonQuery(); myTrans.Commit(); Console.WriteLine("Record is udated."); } catch(Exception e) { myTrans.Rollback(); Console.WriteLine(e.ToString()); Console.WriteLine("Sorry,Record can not be updated."); } finally { myConnection.Close(); }
