Insert truncate query result into a table - ms-access

Question

I have a query reside in a access file(.mdb), I would like to call this query in VBA, and store the result into a existing table. The previous content of the table should be deleted before the result was inserted.
Any idea? In my existing code, the query name "genInboundCdr" was execute via DoCmd.TransferSpreadsheet and result was stored into a excel file.
Private Sub BtnExecuteQuery_Click()
If IsNull(txtOutputPath.value) Then
MsgBox "Please enter a valid output file location."
Else
If ObjectExists("Query", "genInboundCdr") Then
strPathToSave = txtOutputPath.value
MsgBox "About to extract inbound cdr..." & vbCrLf & _
"Please notice that the query may take longer time " & _
"( > 20 minutes ) if the linked tables contains a lot " & _
"of records."
txtStatus.value = txtStatus.value & _
"About to extract inbound cdr..." & vbCrLf & _
"Please notice that the query may take longer time " & _
"( > 20 minutes ) if the linked tables contains a lot " & _
"of records." & vbCrLf
DoCmd.TransferSpreadsheet acExport, _
acSpreadsheetTypeExcel9, _
"genInboundCdr", _
strPathToSave, _
True
MsgBox ("Inbound Cdr generated.")
txtStatus.value = txtStatus.value & "Inbound Cdr generated." & vbCrLf
Else
MsgBox ("Query does not exist! Please review your steps.")
End If
End If
End Sub

Answer 1

The easiest thing to do is execute a delete query on the destination table and then use an append query.
A delete query's SQL looks like this:
DELETE *
FROM foo2;
An append query's SQL likes like this:
INSERT INTO foo_dest ( f0, f1, f2, f3 )
SELECT foo_src.f0, foo_src.f1, foo_src.f2, foo_src.f3
FROM foo_src;
The SELECT portion would be your source query (genInboundCdr).
You can execute either one of these query in VBA like this:
DoCmd.RunSQL = "insert into ..."
or
Currentdb.execute = "insert into ..."
or if you prefer to use stored queries
DoCmd.OpenQuery "genInboundCdr"
(there may be another way to run genInboundCdr, but I can't recall right now)

I end up doing like this:
1) query and store the result into a excel file.
2) import the excel file using transferspreadsheet.
DoCmd.TransferSpreadsheet acExport, _
acSpreadsheetTypeExcel9, _
"genInboundCdr", _
strPathToSave, _
True
DoCmd.TransferSpreadsheet acImport, _
acSpreadsheetTypeExcel9, _
"temp_result", _
strPathToSave, _
True
