下面的VBA子程序将运行大多数的查询就好了。 (即:SELECT * FROM DUAL

Sub DisplayQuery(QueryString As String)
  Dim rs As New ADODB.Recordset
  Dim connStr As String
  connStr = _
   "Provider=MSDAORA.1;" _
   & "User ID=abc;Password=123;" _
   & "Data Source=xxx/xxx;"
  out QueryString

  rs.Open QueryString, connStr, adOpenStatic, adLockOptimistic
  Range("DataTable").Clear
  Cells(1, 1).CopyFromRecordset rs
End Sub

然而,当我运行下面的查询时,下面的错误消息立即弹出:Run-time error '3704':Operation is not allowed when the object is closed.

with all_hours as
  ( select to_date('2009-11-03 05:00 PM','yyyy-mm-dd hh:mi PM') + numtodsinterval(level-1,'hour') hour
      from dual
   connect by level <= 4 /*hours*/

  )
  select h.hour
       , count(case when h.hour = trunc(s.sampled_on,'hh24') then 1 end) sampled
       , count(case when h.hour = trunc(s.received_on,'hh24') then 1 end) received
       , count(case when h.hour = trunc(s.completed_on,'hh24') then 1 end) completed
       , count(case when h.hour = trunc(s.authorized_on,'hh24') then 1 end) authorized
    from all_hours h cross join sample s
   group by h.hour

为什么?

有帮助吗?

解决方案 2

我刚刚改组我的查询(链接),这样我可以把它变成一个视图。然后,我创建Excel中的一个连接,以查看名称

其他提示

如果我没有记错,ADO Command对象有一个默认的超时时间(30秒,我认为),这可能会导致您的问题:应该有像

设置
cn.ConnectionTimeout = (your value here)

这可以扩展。
