Sub tt()
On Error GoTo err_tag
Dim con As New ADODB.Connection
Dim rec As New ADODB.Recordset
con.Open "provider=microsoft.jet.oledb.4.0;data source=d:\1111111111111.MDB", "", "", -1
rec.Open "select zl,mph from mzfw", con, adOpenDynamic, adLockOptimistic, adCmdText
rec.MoveFirst
While Not rec.EOF
Dim str As String
Dim str2 As String
Dim arr() As String
Debug.Print
str = rec.Fields("zl")
str2 = rec.Fields("mph")
rec.MoveNext
Wend
err_tag:
MsgBox "df" '为什么总是运行么这里，是不是还要注意什么事项
Exit Sub
rec.Close
con.Close
Exit Sub
End Sub
