sql - .openrecordsource "run-time error ' 9 1'"

Question

我对以下代码行有疑问，我觉得它很简单，但我无法指出它。我收到运行时错误“91”对象变量或 block 变量未设置错误。错误发生在 rsc.OpenRecordSet... 行。 BadgeV 是一个数字，我安装了 DAO 引用，它是从链接的 SQL Server 表中提取的，我在该表中有主键和标识。我错过了什么？

Function FNC_Scan()
    Dim db As DAO.Database
    Dim rsc As DAO.Recordset

    Set db = CurrentDb()
    rsc.OpenRecordset ("SELECT dbo_ScanData.CardID, dbo_ScanData.Complete FROM dbo_ScanData WHERE (((dbo_ScanData.CardID)= Forms![Scan]!BadgeV))) AND ((dbo_ScanData.Complete)=0));")

    If rsc.EOF Then
        MsgBox "new item"
    Else
        MsgBox "Append Item"
    End If

    Set rsc = Nothing
    Set db = Nothing
End Function

Answer 1

应该是

set rsc = db.OpenRecordset(...)

而不是

rsc.OpenRecordset(...)
