我一直在寻找使用开放参数导出查询的解决方案。我需要将查询导出为格式化的 Excel 电子表格，并且无法为正在使用的数据库创建其他表、查询、表单或报告。我使用 DoCmd.OutputTo 因为它导出格式化的查询，这与 DoCmd.TransferSpreadsheet 不同，但是我似乎无法使用定义的参数导出查询。我需要包含参数，否则用户将被迫输入开始和结束日期三次，因为数据库出于某种原因要求两次 startDate 和 endDate 并且为了保留 Excel 电子表格和随后的 Outlook 部分一致我将不得不要求用户再次输入他们以前的参数
Sub Main()

Dim fpath As String
Dim tname As String
Dim cname As String
Dim tType As AcOutputObjectType
Dim tempB As Boolean
fpath = CurrentProject.path & "\"
'tType = acOutputTable
'tname = "APPROVED SWPS FOR LOOK AHEAD & BAR CHART"
tType = acOutputQuery
tname = "ASFLA&BC Query"
cname = "Temp BPC Calendar"
Dim qdfQry As DAO.QueryDef
Dim strStart As String
Dim strEnd As String
Set qdfQry = CurrentDb().QueryDefs(tname)
'strStart = InputBox("Please enter Start date (mm/dd/yyyy)")
'strEnd = InputBox("Please enter Start date (mm/dd/yyyy)")
qdfQry.Parameters("ENTER START DATE") = FormatDateTime("6/30/12", vbShortDate) 'strEnd
qdfQry.Parameters("ENTER END DATE") = FormatDateTime("7/1/12", vbShortDate) 'strStart
tempB = Backup(fpath, qdfQry, tType)

当前给出的 SQL 如下所示，为清楚起见省略了字段
