VBScript WQL排序结果集？

Question

显然，WQL不包含ORDER BY子句。有没有办法根据其中一列对结果集进行排序？例如：

Set objWMIService = GetObject("winmgmts:{impersonationLevel=impersonate}!\\.\root\cimv2")
sSQL = "Select Time,Source,Event,CategoryNum,Category,TypeNum,Type,User,ComputerName,Insertion1,Insertion2,Data from Win32_NTLogEvent Where Logfile = 'System' and SourceName = 'Service Control Manager'"
Set resultSet = objWMIService.ExecQuery (sSQL)
For Each objEvent In resultSet
    ...
Next

有没有办法按Time列对resultSet进行排序？

Answer 1

WQL确实没有排序子句，因此不可能直接在查询中排序。您可以做的是将返回的数据放入disconnected recordset中，然后对记录集进行排序：

Set DataList = CreateObject("ADOR.Recordset")
DataList.Fields.Append "Time", 7
DataList.Fields.Append "Source", 200, 255
DataList.Fields.Append "Event", 3
...
DataList.Open

Set wmi = GetObject("winmgmts:{impersonationLevel=impersonate}!//./root/cimv2")
qry = "SELECT Time,Source,Event,CategoryNum,Category,TypeNum,Type,User,ComputerName,Insertion1,Insertion2,Data " & _
      "FROM Win32_NTLogEvent " & _ 
      "WHERE Logfile='System' AND SourceName='Service Control Manager'"

For Each evt In wmi.ExecQuery(qry)
    DataList.AddNew
    DataList("Time")   = evt.Time
    DataList("Source") = evt.Source
    DataList("Event")  = evt.Event
    ...
    DataList.Update
Next

DataList.Sort = "Time"
DataList.MoveFirst
Do Until DataList.EOF
    WScript.Echo DataList.Fields.Item("Time") & vbTab & _
        DataList.Fields.Item("Event")
    DataList.MoveNext
Loop

根据需要调整字段的data type。
