我们的要求 -
我们的供应商很少，我们希望在月内生成每个供应商的月度采购报告并导出到excel。我认为解决方案是创建一个参数查询，我可以传递供应商ID，月和年的值。供应商列表不断变化，并存储在单独的表中。所以，基本上，我应该能够从该表中顺序读取供应商ID，并作为参数传递给我的查询，以便为该供应商生成报告。
我找到的最接近我的要求的解决方案（性质相似） -
Exporting Recordset to Spreadsheet
为什么我认为可以有更好的解决方案 -
在建议的解决方案中，我们创建了多个查询并删除了这些查询。从概念上讲，我觉得应该有一种方法来创建参数查询并使用do while循环将参数的值（上例中的DeptName）顺序传递给查询并将结果导出到excel。
如果我可以使用vba将值传递给参数查询，我应该能够实现这一点。而这正是我尚未弄清楚的。

以下是我写的代码 -
Private Sub Monthly_Supplier_Sales_Report_Click()
Dim strDirectoryPath As String
Dim DateFolderName As String
DateFolderName = Format$((DateSerial(year(Date), month(Date), 1) - 1), "YYYY MM")
strDirectoryPath = "C:\dropbox\Accounting\Sales Reports\" & DateFolderName
If Dir(strDirectoryPath, vbDirectory) = "" Then MkDir strDirectoryPath
Dim Filename As String
Dim strSQL1 As String
Dim strSQL2 As String
Dim DesignerCode As String
Dim month1 As String
Dim year1 As Integer
Dim Query1 As DAO.QueryDef
Dim query2 As DAO.QueryDef
Dim rsDesigner As DAO.Recordset
Set rsDesigner = CurrentDb.OpenRecordset("Designer Details Master")
Do While Not rsDesigner.EOF
DesignerCode = rsDesigner![Designer Code]
month1 = "Jan" 'right now hardcoded, will call this programatically
year1 = 2014 'right now hardcoded, will call this programatically
strSQL1 = "SELECT * FROM [Sales Report Generation Data] WHERE [designer code] = '" & DesignerCode & "' AND [Shipping Month]= '" & month1 & "' AND [Shipping Year]=" & year1
strSQL2 = "SELECT * FROM [Sales Report Generation - Monthwise Inventory Snapshot] WHERE [designer code] = '" & DesignerCode & "' AND [Snapshot Month]= '" & month1 & "' AND [Snapshot Year]= " & year1
Set Query1 = CurrentDb.CreateQueryDef(Name:="TempSalesQuery", SQLText:=strSQL1)
Set query2 = CurrentDb.CreateQueryDef(Name:="TempInventoryQuery", SQLText:=strSQL2)
Filename = strDirectoryPath & "\" & DesignerCode & Format$(Now(), " yyyy mm") & ".xls"
DoCmd.TransferSpreadsheet acExport, acSpreadsheetTypeExcel9, "TempSalesQuery", Filename, False, "Sales Report"
DoCmd.TransferSpreadsheet acExport, acSpreadsheetTypeExcel9, "TempInventoryQuery", Filename, False, "Inventory"
CurrentDb.QueryDefs.Delete "TempSalesQuery"
CurrentDb.QueryDefs.Delete "TempInventoryQuery"
rsDesigner.MoveNext
Loop
End Sub
相反，我想申请的逻辑是 -
Do While Not
assign Value to Parameter 1 = rsDesigner![Designer Code]
assign Value to Parameter 2 = Month1
assign Value to Parameter 3 = Year1
Run the two Parameter queries, for which about three parameters are the input value and export to excel in respective sheets.
Loop
只是我还没弄清楚 - 如何实现这一目标。
这是一个解决方案。请注意，我创建了两个查询将使用的函数。只需创建两个查询并保存它们（请参阅下面的示例SQL），添加代码以选择日期，一切都应该没问题。
