ADO.NET事务和SQL Server 2008事务

我刚刚用 C 2008,SQL Server 2005 使用下面的代码和 它确实回滚了 .

SqlConnection con = new SqlConnection("server=svr;database=db;uid=user;pwd=pw;Connect Timeout=900");
SqlCommand cmd = con.CreateCommand();
cmd.CommandType = CommandType.StoredProcedure;
cmd.CommandText = "MySp";
con.Open();
SqlTransaction trans = con.BeginTransaction();
cmd.Transaction = trans;
cmd.ExecuteNonQuery();
trans.Rollback();  // or trans.Commit()
con.Close();

数据库代码

CREATE TABLE [dbo].[TEST](
    [Val] [int] NULL
)

ALTER PROCEDURE MySp
AS 
BEGIN
    BEGIN TRANSACTION T1
    INSERT INTO TEST SELECT 1
    COMMIT TRANSACTION T1
END
