C# 取消上次在数据库中进行的更新

我有一个主表和一个与之关联的明细表，通过引用

主表_gid

，我必须在主表中插入摘要，在明细表中插入详细信息。一切正常。我将遵循以下场景：

插入主表

如果主表插入成功，则插入详细表

如果详细表插入失败，则从主表中删除引用字段

这次一切都很顺利

在更新的情况下i遵循相同的场景，但在详细表插入失败的情况下面临问题。如果细节表插入失败，我如何

撤消主表中的最后一次更新（使用query）。
我使用
导入System.Data.Odbc
连接到
mysql
以下是msdn中关于

End Sub
如果您使用的是
ado.net
，则可以使用
命令类的
事务
。请参阅更新：am using
Imports System.Data.Odbc
Public Sub ExecuteTransaction(ByVal connectionString As String)

Using connection As New OdbcConnection(connectionString)
    Dim command As New OdbcCommand()
    Dim transaction As OdbcTransaction

    ' Set the Connection to the new OdbcConnection.
    command.Connection = connection

    ' Open the connection and execute the transaction. 
    Try
        connection.Open()

        ' Start a local transaction.
        transaction = connection.BeginTransaction()

        ' Assign transaction object for a pending local transaction.
        command.Connection = connection
        command.Transaction = transaction

        ' Execute the commands.
        command.CommandText = _
            "Insert into Region (RegionID, RegionDescription) VALUES (100, 'Description')"
        command.ExecuteNonQuery()
        command.CommandText = _
            "Insert into Region (RegionID, RegionDescription) VALUES (101, 'Description')"
        command.ExecuteNonQuery()

        ' Commit the transaction.
        transaction.Commit()
        Console.WriteLine("Both records are written to database.")

    Catch ex As Exception
        Console.WriteLine(ex.Message)
        ' Try to rollback the transaction 
        Try
            transaction.Rollback()

        Catch 
            ' Do nothing here; transaction is not active. 
        End Try 
    End Try 
    ' The connection is automatically closed when the 
    ' code exits the Using block. 
End Using
