如何从 GetRows() 获取列数？

Question

如何只取一个SQL数组？我永远看不到带有“noOfColumns3”的行。 SQL 正在运行。

Function getSubmittalNotes(submitId)
    Dim note_list, note_conn
    Dim test
    Set note_conn = Server.CreateObject("ADODB.Connection")
    note_conn.Open Application("DSN")
    Set note_list = Server.CreateObject("ADODB.Recordset")
    note_list.CursorLocation = 3
    note_list.Open "SELECT [ID], [SubmitID], [UserID], [EnteredTime], [Note] FROM [dbo].[SubmittalNotesHistory] where [SubmitID] = " & submitId, note_conn, 1, 3
    'set notes = note_list.GetRows
    If note_list.RecordCount = 0 Then
        test = ""
        Response.Write "noOfColumns123 : <BR>"
    Else
        note_list.MoveFirst
        test = note_list.GetRows
        Response.Write "noOfColumns3 : " & test & "<BR>"
    End If
    note_list.Close
    Set note_list = Nothing
    note_conn.Close
    Set note_conn = Nothing
    Response.Write "getSubmittalNotes : " & test & " <BR>"
    getSubmittalNotes = test
End Function

Answer 1

尝试改变

test = note_list.GetRows
Response.Write "noOfColumns3 : " & test & "<BR>"

到

test = note_list.GetRows
Response.Write "noOfColumns3 : " & UBound( test ) & "<BR>"
