I got a problem that I'm hoping some fresh minds can help me out here.
First some background:

I have a table in an Access database which I need to update with new
information - call the table "Raw". Said new information comes in the
form of an Excel spreadsheet. The gotcha with the spreadsheet is that
there is a very good chance that there can be information within the
spreadsheet that is identical to some records within Raw, so I cannot
simply append the info from the spreadsheet to the end of Raw. So
here's what I wrote (note it uses Ken Getz's code to use the the Open
File dialog box):

   'make sure bounce tables are empty
   CurrentDb.Execute "DELETE * FROM Raw_copy", dbFailOnError
   CurrentDb.Execute "DELETE * FROM spreadsheet", dbFailOnError
   'find file to import
   strFilter = ahtAddFilterItem(strFilter, "Excel Files (*.XLS)",
"*.XLS")
   strInputFileName = ahtCommonFileOpenSave( _
               Filter:=strFilter, OpenFile:=True, _
               DialogTitle:="Please select an input file...", _
               Flags:=ahtOFN_HIDEREADONLY)
   'import new Excel sheet
   DoCmd.TransferSpreadsheet acImport, acSpreadsheetTypeExcel5, _
       "spreadsheet", strInputFileName, True
   'append info to end of Raw
   DoCmd.SetWarnings False
   strSQL = "INSERT INTO Raw SELECT spreadsheet.* FROM spreadsheet;"
   DoCmd.RunSQL strSQL
   'move to Raw_Copy to clear out any dupe info
   strSQL = "INSERT INTO Raw_Copy SELECT Raw.* FROM Raw;"
   DoCmd.RunSQL strSQL
   'move back to Raw
   CurrentDb.Execute "DELETE * FROM Raw", dbFailOnError
   strSQL = "INSERT INTO Raw SELECT Raw_Copy.* FROM Raw_Copy;"
   DoCmd.RunSQL strSQL
   DoCmd.SetWarnings True

The table "Spreadsheet" is simply an empty copy of the Raw table, left
there to let the import wizard know what field format it's working
with. The table Raw_copy is identical to the table Raw, except it has
the duplicate fields set as primary keys.

That all works fine, except I find the file bloats up about 3 times
after it's run for the first time after a database compact, and I have
no inclination to discover how much bigger it'll bloat each subsequent
import operation after the first! So what I would like to do is to move
the assorted copy functions over to a temp database, using the info
found here: http://www.granite.ab.ca/access/temptables.htm

So here's what I've done so far:

   'make sure bounce tables are empty
   CurrentDb.Execute "DELETE * FROM Raw_copy", dbFailOnError
   CurrentDb.Execute "DELETE * FROM spreadsheet", dbFailOnError
   'find file to import
   strFilter = ahtAddFilterItem(strFilter, "Excel Files (*.XLS)",
"*.XLS")
   strInputFileName = ahtCommonFileOpenSave( _
               Filter:=strFilter, OpenFile:=True, _
               DialogTitle:="Please select an input file...", _
               Flags:=ahtOFN_HIDEREADONLY)
   'create temp mdb to hold data while we work on it
   Set wrkDefault = DBEngine.Workspaces(0)
   strTempDatabase = Left$(CurrentDb.Name, Len(CurrentDb.Name) - 4) &
" temp.mdb"
   If Dir(strTempDatabase) <> "" Then Kill strTempDatabase
   Set dbsTemp = wrkDefault.CreateDatabase(strTempDatabase,
dbLangGeneral)
   'copy spreadsheet table over
   DoCmd.CopyObject strTempDatabase, , acTable, "spreadsheet"
   'copy Raw_copy table over
   DoCmd.CopyObject strTempDatabase, , acTable, "Raw_copy"
   'copy Raw table over
   DoCmd.CopyObject strTempDatabase, , acTable, "Raw"

Which works. Here's the newbie question: how do I tell the macro that
the next few operations from the "import the Excel spreadsheet" through
to "move to Raw_copy" are to be done with the tables in the temp
database and not with the ones in the main version?  :)

Mind you, if someone can point out a cleaner way of doing all this, be
my guest...
