请教老师 能帮忙看一看吗？   如何用EXCEL VBA SQL语句删除表中多余的重复记录（多个字段）只保留一条

Option Explicit

Dim cnn As New ADODB.Connection
Dim rst As New ADODB.Recordset
Dim sqls As String
Dim i As Integer

Sub SQLDELEDUPLICATERECORD()
    '' Excel VBA SQL 删除表中多余的重复记录多个字段）只保留一条
    SQLTEST = "SQLTEST.xls"
    Workbooks(SQLTEST).Worksheets(1).Activate

    DBSFullName = MYPath + SQLTEST
    If cnn.State = adStateOpen Then
        cnn.Close
        Set cnn = Nothing
    End If
   
    cnn.Open "Provider=Microsoft.Jet.OLEDB.4.0;Extended Properties=Excel 8.0;Data Source=" & DBSFullName  ''ThisWorkbook.FullName
    If cnn.State = adStateOpen Then
        '' 以下两种 SQL语句都失败 请教如何修改
        sqls = ""
        sqls = sqls + "delete from [Sheet1$] a "
        sqls = sqls + "where (a.PurchaseOrderNo,a.OrderDate) in (select PurchaseOrderNo,OrderDate from [Sheet1$] group by PurchaseOrderNo,OrderDate having count(*) > 1) "
        sqls = sqls + "and PurchaseOrderNo not in (select min(PurchaseOrderNo) from [Sheet1$] group by PurchaseOrderNo,OrderDate having count(*)>1)"
