我做的保存代码。
可以用，但是，总想找个更好的办法。
拿来给大家探讨一下。
Private Sub 保存_Click()
'这个怎么做？
'关键是子记录数可能变动，可能大于原记录数，也可能小于原记录数。
Dim rs As New ADODB.Recordset
Dim rst As New ADODB.Recordset
Dim rsc As New ADODB.Command
'delete old
rsc.ActiveConnection = CurrentProject.Connection
rsc.CommandType = adCmdText
rsc.CommandText = "delete from 订单明细 where 订单号='" & Me.订单号 & "'"
rsc.Execute
'addnew
Set rs = Me.订单明细子窗体.Form.RecordsetClone
rst.Open "select * from 订单明细", CurrentProject.Connection, adOpenKeyset, adLockOptimistic
Do While Not rs.EOF
With rst
.AddNew
!订单号 = Me.订单号
!产品名称 = rs.Fields("产品名称")
!产品数量 = rs.Fields("产品数量")
.Update
End With
rs.MoveNext
Loop
rs.Close
Set rs = Nothing
rst.Close
Set rst = Nothing
Set rsc = Nothing
MsgBox "保存成功"

数据表子窗体数据保存对于access来说是个世界难题
有人用临时表处理、有人用链接表处理
要是想通过代码完成相当有难度
