此代码使用dlookup为matchstr_t生成运行时错误3464。我无法理解为什么matchstr_v似乎工作得很好。有什么优惠？目前我所要做的就是使用dlookup来标记约会的重复开始时间。

Dim i, j, clientid, therid As Integer
Dim origin_date, apptdate  As Date
Dim slotday, apptype, venue, matchstr_v, matchstr_t As String
Dim slottime As Date
Dim appt(25) As Date
Dim db As Database
Dim rst As Recordset
Dim test As Variant

origin_date = Date
slotday = Me.slot_day.Value
slottime = Me.slot_time.Value
clientid = Me.Client_ID.Value
therid = Me.Therapist_ID.Value
venue = Me.venue.Value
apptype = "continuation"

slottime = Format(slottime, "Short Time")
For i = 1 To 7
    apptdate = Date + i
    If Weekday(apptdate, 2) = slotday Then
    'set up stuff
    For j = 0 To 25
        appt(j) = apptdate + (j * 7)

        Set db = CurrentDb()
        Set rst = db.OpenRecordset("Dummy")

        Debug.Print "[therapist ID] = " & therid
        matchstr_v = "[appt date]= #" & appt(j) & "# AND [appt time] = #" & slottime & "# AND [venue] = '" & venue & "'"
        matchstr_t = "[appt date]= #" & appt(j) & "# AND [appt time] = #" & slottime & "# AND [therapist ID] = " & therid
        Debug.Print matchstr_t
        If Not IsNull(DLookup("[dummy ID]", "Dummy", matchstr_v)) Then
            ' do more stuff
        ElseIf Not IsNull(DLookup("[dummy ID]", "Dummy", matchstr_t)) Then
            ' do more stuff
        Else
            rst.AddNew
            rst.Fields("appt date") = appt(j)
            rst.Fields("appt time") = slottime
            rst.Fields("Client ID") = clientid
            rst.Fields("Therapist ID") = therid
            rst.Fields("appt type") = "continuation"
            rst.Fields("attendance") = "scheduled"
            rst.Fields("venue") = venue
            'Debug.Print rst.Fields("appt date")
            rst.Update
            test = (DLookup("[dummy ID]", "Dummy", matchstr_v))
            Debug.Print test
        End If
        rst.Close
        db.Close
    Next j
    Else
    End If
Next i

Answer 1

[治疗师ID]的数据类型是什么？

似乎数据类型与therid的值不匹配。

Answer 2

在这种情况下，你可能只是错过了一个＃

matchstr_t =“[appt date] =＃”＆amp; appt（j）＆amp; “＃AND [appt time] =＃”＆amp;时段和时间“＃AND [治疗师ID] = ＃”＆amp; therid

多个dlookup标准出错
