*
* @return void
*/
public function seek($row)
{
switch ($this->mode) {
case "mysql":
$this->result->data_seek($row);
break;
case "postgres":
case "redshift":
pg_result_seek($this->result, $row);
break;
case "odbc":
# The odbc driver doesn't support seeking, so we fetch specific rows in getNextRow(), and here all we need to do is set the current position instance variable
break;
case "sqlite":
$this->result->reset();
for ($i = 0; $i < $row; $i++) {
$this->result->fetchArray();
}
break;
case "mssql":
