Data provider or other service returned an E_FAIL status

Hello,

I'm trying to run a piece of code which copies data from a Database table and paste it in a spreadsheet.

But I get the error "Data provider or other service returned an E_FAIL status." at the highlighted line.

  var dbTable = conn.Execute_(execQuery); 

  var excel = Sys.OleObject("Excel.Application");
  var wb = excel.Workbooks.Open(fileName);
  var ws = wb.Sheets.Item(sheetName);
  excel.DisplayAlerts = false;

  // Copy All field names
  for (var i = 0; i < dbTable.Fields.Count ; i++)
    ws.Cells.Item(1, i + 1).Value = dbTable.Fields.Item(i).Name;
  // Scans all records returned by the query
  Log.Message("Total Fields: " +dbTable.Fields.Count);
  dbTable.MoveFirst();
  var RowIndex = 2;
  while (! dbTable.EOF)
{
    for (i = 0; i < dbTable.Fields.Count; i++)
      ws.Cells.Item(RowIndex, i + 1).Value = dbTable.Fields.Item(i).Value;
dbTable.MoveNext();
RowIndex++;

Any suggestions or help would really be appreciated!

Thank you
