如何使用vba将临时记录集导出到csv文件

Question

我有一个ms访问表,跟踪50个产品及其每日销售量.我想使用vba 1 csv文件(包括标题)导出每个产品,显示记录集中的每日卷而不将记录集保存到永久查询.我正在使用下面的代码,但我被困在代码中下面突出显示的实际导出点.任何帮助解决这个问题表示赞赏.

Dim rst As Recordset
Dim rstId As Recordset

    SQLExportIds = "SELECT DISTINCT tblDailyVols.SecId FROM tblDailyVols WHERE tblDailyVols.IsDeleted=False"
    Set rstId = CurrentDb.OpenRecordset(SQLExportIds)
        If rstId.EOF = True Then
            MsgBox "No Products Found"
            Exit Sub
        End If

        Do While rstId.EOF = False
            SecId = rstId.Fields("SecId")
            SQLExportQuotes = " SELECT tblDailyVols.ID , tblDailyVols.TradedVolume, tblDailyVols.EffectiveDate  FROM tblDailyVols "
            SQLExportQuotes = SQLExportQuotes & " WHERE  tblDailyVols.IsDeleted=False and tblDailyVols.ID = " & SecId
            SQLExportQuotes = SQLExportQuotes & " ORDER BY tblDailyVols.EffectiveDate "


        Set rst = CurrentDb.OpenRecordset(SQLExportQuotes)
            If rst.EOF = True Then
             MsgBox "No Quotes Found"
             Exit Sub
            End If

            IDFound = rst.Fields("ID")
            OutputPlace = “C:\Output”  & IDFound & ".csv"

            Set qdfTemp = CurrentDb.CreateQueryDef("", SQLExportQuotes)
            **DoCmd.TransferText acExportDelim, , 1, OutputPlace, True** <--This Here Line Fails
            Set rst = Nothing
          rstId.MoveNext
        Loop
        Set rstId = Nothing

Answer 1

您必须为TransferText创建一个实际命名的QueryDef对象才能使用,但之后您可以删除它.像这样的东西:

Set qdfTemp = CurrentDb.CreateQueryDef("zzzTemp", SQLExportQuotes)
Set qdfTemp = Nothing
DoCmd.TransferText acExportDelim, , "zzzTemp", OutputPlace, True
DoCmd.DeleteObject acQuery, "zzzTemp"
