我剛接觸wincc，現在要在wincc里做一個月報表，需要每天在當天結束時將數據庫中的日表里的每項數據讀出來求平均值再寫入月表里，現在沒辦法實現數據讀取，可能是連接不到數據庫，
Dim objConnection
  Dim strConnectionString
  Dim opertime,device,command
  Dim strSQL
  Dim objCommand
  Dim DsnStr
  Dim dt
  Dim PV1,PV2,PV3,PV4,PV5,PV6,PV7,PV8,PV9,PV10,PV11,PV12,PV13,PV14,PV15,PV16
  Dim iday,imonth,iyear,ihour

  DsnStr="CC_sheet"
  strConnectionString = "Provider=MSDASQL;DSN="&DsnStr&";database=repotrdb;UID=sa;PWD=;"

  dt=Now() '系統(tǒng)時間
    imonth=Month(dt)
    iyear=Year(dt)
    iday=Day(dt)
    ihour=Hour(dt)
pv4="select influx from daydata where zyear="& iyear &  " And zmonth= " &imonth & "And zday=" & iday & " "
MsgBox pv4
'Set objConnection = CreateObject("ADODB.Connection")
'objConnection.ConnectionString = strConnectionString
  objConnection.Open
Set objCommand = CreateObject("ADODB.Command")
HMIRuntime.Trace strsql
objCommand.ActiveConnection = objConnection
objCommand.CommandText = strSQL
objCommand.Execute
objcomand
Set objCommand = Nothing
objConnection.Close
Set objConnection = Nothing

SQL語句在報表編輯器中的動態(tài)表格中測試是可以的

哪位高手知道的指點一下，急~~~~~
