问题描述
我有一个很大的记录要复制,然后用新版本的表单打开一个带有新主键ID的表单.可以在Access VBA中完成此操作,而不必遍历所有字段来复制数据吗?
I have a very large record that I'm trying to duplicate, then open a form with the new version with a new primary key ID. Can this be done in Access VBA without having to iterate through all the fields to copy the data?
谢谢!
推荐答案最快和最简单的方法是使用DAO和以下形式的 RecordsetClone :
The fastest and simplest way is to use DAO and the RecordsetClone of the form:
Private Sub cmdDuplicate_Click() Dim rstSource As DAO.Recordset Dim rstInsert As DAO.Recordset Dim fld As DAO.Field If Me.NewRecord = True Then Exit Sub Set rstInsert = Me.RecordsetClone Set rstSource = rstInsert.Clone With rstSource If .RecordCount > 0 Then ' Go to the current record. .Bookmark = Me.Bookmark With rstInsert .AddNew For Each fld In rstSource.Fields With fld If .Attributes And dbAutoIncrField Then ' Skip Autonumber or GUID field. ElseIf .Name = "SomeFieldToPreset" Then rstInsert.Fields(.Name).Value = SomeValue ElseIf .Name = "SomeFieldToExclude" Then ' Leave blank Else ' All other fields. ' Copy field content. rstInsert.Fields(.Name).Value = .Value End If End With Next .Update ' Go to the new record and sync form. .MoveLast Me.Bookmark = .Bookmark .Close End With End If .Close End With Set rstInsert = Nothing Set rstSource = Nothing End Sub这会将表单从当前记录移到新记录.您可以轻松地对其进行修改以选择新的ID,然后使用新记录打开其他表单.
This moves the form from the current record to the new record. You can easily modify that to pick the new ID and open the other form with the new record.
