I ran following query on DB through PHPmyAdmin
SELECT * FROM field_data_field_country_feed WHERE entity_id=40848
And it worked and returned me the single row But when I try to implement that in my custom services it is not returning anything.
$result1 = db_query("SELECT * FROM field_data_field_country_feed WHERE entity_id=40848")->fetchAll();
var_dump($result1);
Please help
