如何使用VBA将临时记录集导出为CSV文件 [英] How to export a temporary recordset to a csv file using vba

问题描述

我有一个MS Access表，跟踪50种产品的日销售量。我想使用VBA 1 CSV文件(包括标头)为每个产品导出，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，但我被困在下面代码中突出显示的实际导出的点上。 如能协助解决此问题，我们将不胜感激。

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

QueryDef

您必须创建一个实际命名的推荐答案对象以使用TransferText，但随后只需将其删除。大概是这样的：

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