存储过程执行的简单问题。

Question

如果在我的存储过程里，如果有三个操作。
一个是A表的Insert。
另一个是B表的Update
还有一个是C表的Delete请问如果是在C表执行的时候出错了。那么上面的两个操作是否也无效了？

Answer 1

begin transaction  ,commit transaction

Answer 2

如果三个表相互关联的话，建议做成事物处理，MSDN代码如下
private static void ExecuteSqlTransaction(string connectionString)
{
    using (SqlConnection connection = new SqlConnection(connectionString))
    {
        connection.Open();        SqlCommand command = connection.CreateCommand();
        SqlTransaction transaction;        // Start a local transaction.
        transaction = connection.BeginTransaction("SampleTransaction");        // Must assign both transaction object and connection
        // to Command object for a pending local transaction
        command.Connection = connection;
        command.Transaction = transaction;        try
        {
            command.CommandText =
                "Insert into Region (RegionID, RegionDescription) VALUES (100, 'Description')";
            command.ExecuteNonQuery();
            command.CommandText =
                "Insert into Region (RegionID, RegionDescription) VALUES (101, 'Description')";
            command.ExecuteNonQuery();            // Attempt to commit the transaction.
            transaction.Commit();
            Console.WriteLine("Both records are written to database.");
        }
        catch (Exception ex)
        {
            Console.WriteLine("Commit Exception Type: {0}", ex.GetType());
            Console.WriteLine("  Message: {0}", ex.Message);            // Attempt to roll back the transaction.
            try
            {
                transaction.Rollback();
            }
            catch (Exception ex2)
            {
                // This catch block will handle any errors that may have occurred
                // on the server that would cause the rollback to fail, such as
                // a closed connection.
                Console.WriteLine("Rollback Exception Type: {0}", ex2.GetType());
                Console.WriteLine("  Message: {0}", ex2.Message);
            }
        }
    }
}
