											Private Sub Form_Load()
  Dim DBRain As New ADODB.Connection
  Dim DBRainpath As String
  DBRainpath = App.Path & "\mdb\rain.mdb"
  DBRain.Provider = "Microsoft.Jet.OLEDB.4.0"
  DBRain.Open DBRainpath
  Dim MySQL As String
  Dim MyRst As New ADODB.Recordset
  Dim a As String
  a = "过程持续时间"
  MySQL = "Select 过程持续时间 from 最大过程雨量50"
  MyRst.Open MySQL, DBRain, adOpenDynamic, adLockOptimistic
End Sub
  
  把 MySQL改为MySQL = "Select a from 最大过程雨量50"
  出现如图所示错误
   把MySQL改为MySQL = "Select * from 最大过程雨量50"
