编写一个 SQL 查询，从过滤后的日期列中选择数据

Question

我正在尝试在 Access 中查询交叉表/记录集（在 Excel 表上尝试过 ADO），其中列中有日期，例如

如果我想提取仅包含 2014 年列的有限数据，我该如何编写这样的查询？ 请注意，这些列可能会有所不同。

像这样的东西，虽然可能有更简单的方法

Sub Akward_Query()

Dim strSQL As String
Dim strSQL2 As String
Dim rst As ADODB.Recordset
Dim fld As ADODB.Field
Dim intYear As Integer

intYear = 2014

strSQL = "Select top 1 * from tbl_Test"

Set rst = New ADODB.Recordset

rst.Open strSQL, CurrentProject.Connection, 1

strSQL2 = "Select "

For Each fld In rst.Fields

    If InStr(1, fld.Name, "Week Ending") > 0 And InStr(1, fld.Name, intYear)>0 Then

        strSQL2 = strSQL2 & "[" & fld.Name & "],"

    End If

Next fld

If Right(strSQL2, 1) = "," Then strSQL2 = Left(strSQL2, Len(strSQL2) - 1)

strSQL2 = strSQL2 & " from tbl_Test"

End Sub
