I am using mysql database.
example:
$regional_data_tbl="abc";
$report_id="1234";
$node_data="Axillary (Level I, II & III) - Left";

$saved_data = $conn->table($regional_data_tbl)->setFetchMode(PDO::FETCH_ASSOC)->where('report_id', ' = ', $report_id)->where('specimen_id', ' = ', $val->id)->where('level_node', ' = ',$node_data)->get();
