标题：[求助] 帮我看一下我写的代码对不对

 我在项目属性—项目事件—BeforeLoadOuterTable中写代码，到是能用，就是觉得怕把系统崩溃了，请狐爸帮我重新写一下吧！

If e.DataTableName = "yonghu" AndAlso e.User.Name = "城西" Then
    e.SelectString = "Select * From {yonghu} where [pian] In ( '城西 ')"
End If
If e.DataTableName = "yonghu" AndAlso e.User.Name = "城北" Then
    e.SelectString = "Select * From {yonghu} where [pian] In ( '城北 ')"
End If
If e.DataTableName = "yonghu" AndAlso e.User.Name = "城南" Then
    e.SelectString = "Select * From {yonghu} where [pian] In ( '城南 ')"
End If

代码没有错，不过可以简化为：

If e.DataTableName = "yonghu"
    Select Case e.User.name
        Case "城西","城北","城南"
            e.SelectString = "Select * From {yonghu} where [pian] =  '" & e.User.Name & "'"
    End Select
End If

亲爱的狐爸！怎样编写帮助文件呀！

备份数据后，如果遇到数据库损坏，如何再恢复数据呢？你说是备份SQLServer2000里的数据库文件，在恢复时能恢复FOXtable里面的数据吗
