请各位老师指点,如何在已有ACCESS数库中,如何跟据已有的ACCESS数据表结构各字段属性,创建一份一样的空数据表
最好是通过窗体动态的创建,下面是我自己写的一段代码,但运行不成功
Private Sub CommandButton1_Click() '新建数据表
Dim cmd As New ADODB.Command
Dim mytable As String
Dim myoldtable As String
mytoldable = ComboBox1 '已有数据表名称
mytable = TextBox1 '创建数据表名称
Call mydata '建立与数据连接
'判断新建数据表名是否已经存在
Set rst = CNN.OpenSchema(adSchemaTables)
Do While Not rst.EOF
If LCase(rst!TABLE_NAME) = LCase(mytable) Then
MsgBox "数据表已存在!", vbCritical, "警告"
Exit Sub
End If
rst.MoveNext
Loop
Set cmd.ActiveConnection = CNN
sql = "select * into " & mytable & " from " & myoldtable & " where 1 <> 1"
With cmd
.CommandText = sql
.Execute , , adCmdTextExecute
End With
CNN.Close
Set rst = Nothing
Set cmd = Nothing
Set CNN = Nothing
MsgBox "数据表<" & mytable & ">创建成功!", vbInformation, "创建数据表"
End Sub |
