Question

From XL to Access with DAO

Asked by: batdan

I have a program written within Excel VBA which at some point need to take a table from a worksheet, and use the data to create a new table in an Access database I have connected to prevoiusly.

Everything seems to be running OK, but when I look at the database afterwards, it is clear that the new table is in fact a link to the Excel sheet, rather than a table in it's own right (which is what I want).

Here is the code I am using:

Const DATABASE_PATH As String = "C:\workarea\trial.mdb"

Global strWorkbookPath As String

Sub Transfer_To_Access()

    Dim ws As Worksheet
    Dim dbTrial As Database
    Dim rsInstrument As Recordset

    strWorkbookPath = ThisWorkbook.Path

    Set dbTrial = DBEngine.OpenDatabase(DATABASE_PATH)

    For Each ws In ThisWorkbook.Worksheets

        If Left(ws.Name, 6) = "(Data)" Then
       
            If CheckTable(dbLimits, ws.Name) = True Then
                Debug.Print ws.Name
            Else
                addTable dbTrial, ws.Name
            End If
           
        End If

    Next ws

    dbTrial.Close

    Set ws = Nothing
    Set dbTrial = Nothing
    Set rsInstrument = Nothing

End Sub


Sub addTable(dbTemp As Database, strTableName As String)

    Dim tblNewInstrument As TableDef
    Dim dataSource As String

    dataSource = "Excel 8.0;DATABASE=" & strWorkbookPath & "\" & _
                                                ThisWorkbook.Name

    strTableName = "TrialTable"

    Set tblNewInstrument = dbTemp.CreateTableDef(Name:=strTableName)
                   
    With tblNewInstrument
                   
        .Connect = dataSource
        .SourceTableName = strTableName
   
    End With
   
    dbTemp.TableDefs.Append tblNewInstrument
   
    Set tblNewInstrument = Nothing

End Sub


Public Function CheckTable(dbTemp As Database, strTableName As String) As Boolean

    Dim rsTemp As Recordset
    Dim strSQL As String
    Dim result As Boolean
   
    result = True
    strSQL = "SELECT * FROM [" & strTableName & "];"
   
    On Error GoTo noTable

    Set rsTemp = dbTemp.OpenRecordset(strSQL, dbOpenSnapshot)

    CheckTable = result

    Exit Function
   
noTable:

    result = False
    Resume Next

End Function

If anyone can help me to get a proper table in Access rather than just a link to an Excel sheet you would stop me from driving myself insane!

Thanks

Does it work if you remove the line:

    .Connect = dataSource

Connect is used to specify the source of data for a sql pass-through query or linked table.  So it looks like you are pointing the table back to Excel with the connect string.

Okay, so I haven't adapted this code to your particular situation, but it seems to work.  It actually imports the table instead of linking to it.  Here it is:

Dim oAccess As Access.Application
Dim sDatabaseName As String

Set oAccess = New Access.Application

sDatabaseName = "h:\program files\microsoft visual studio\vb98\nwind.mdb"

oAccess.OpenCurrentDatabase sDatabaseName
oAccess.DoCmd.TransferSpreadsheet acImport, acSpreadsheetTypeExcel5, "MyImport", "c:\temp\testexp.xls", True

oAccess.CurrentDb().Close
Set oAccess = Nothing

End Sub


I think an adaptation of this code may solve your problem.  It not, let me know.

 

by: brewdogPosted on 1999-04-08 at 09:21:28ID: 1502778

I'm thinking that you would have to create the fields first and then append them to the table before you append the table to the db in Access. Otherwise, Access doesn't know what information to put in there, I don't think . . .

ryanvs:
I can see what you are saying, but if I just remove that line then there will be no reference to the Excel workbook at all.

mkmccreary:
Although I didn't really want to use automation, your method seems to work fine for my needs.  Thanks.  If you re-post as an answer I will grade.

Thanks to all.
