ms-access-2003 - 循环遍历记录集以使用 SQL 查询的结果填充列表框？

Question

我有一个多选列表框，我希望它成为 sql 查询的来源，结果显示在列表框中。目前，我将结果转到一个记录集，当只选择一个 1 字段时，该记录集显示得很漂亮。例如，如果用户选择 Gender，则不会打开任何记录集数据表，并且 List20 会显示字段名称，下划线，其下方带有不同的值——完美！！当我尝试选择多个项目时，事情就会出错。例如，选择 2 个项目（性别、界面）将导致性别（下划线），但其下方有 2 个 F 和 2 个 M，并且没有任何界面字段值。如何遍历每个选择并让它们显示在列表框中？这是我的代码。另外，奇怪的是，当我运行查询时，List13 没有显示任何结果，但是当我删除该行时：Set Me.List13。Recordset = rs 将打开一个记录集数据表，并且所需的结果不再出现在 List20 中。请帮忙！

Private Sub Command19_Click()
Dim strSQL As String
Dim strCriteria As String
Dim varItem As Variant
Dim dbs As Database
Set dbs = CurrentDb()
Dim qdf As QueryDef
Dim rs As Recordset

On Error GoTo Err_Command19_Click

For Each varItem In Me!List101.ItemsSelected
strCriteria = strCriteria & ",'" & Me!List101.ItemData(varItem) & "'"
Next varItem

strCriteria = Right(strCriteria, Len(strCriteria) - 1)

strSQL = "SELECT DISTINCT " & strCriteria & " FROM Scrubbed"
strSQL = Replace(strSQL, "'", "")

Set rs = dbs.OpenRecordset(strSQL)
Do Until rs.EOF
Set Me.List20.Recordset = rs
Set Me.List13.Recordset = rs
Loop

With dbs
Set qdf = .CreateQueryDef("TmpDistinctValues", strSQL)
DoCmd.OpenQuery "TmpDistinctValues"
.QueryDefs.Delete "TmpDistinctValues"
End With
dbs.Close
qdf.Close

你的意思肯定是：

For Each varItem In Me!List101.ItemsSelected
   strCriteria = strCriteria & "," & Me!List101.ItemData(varItem) 
   colcount = colcount + 1
   colwidths = colwidths & ";" & "1134"
Next varItem

strCriteria = Right(strCriteria, Len(strCriteria) - 1)

strSQL = "SELECT DISTINCT " & strCriteria & " FROM Scrubbed"
''strSQL = Replace(strSQL, "'", "")

''Set rs = dbs.OpenRecordset(strSQL)
''Do Until rs.EOF
Me.List20.RowSource = strSQL
Me.List20.ColumnCount = colcount
Me.List20.ColumnWidths = Mid(colwidths, 2)

''Set Me.List13.Recordset = rs
''Loop
