php - Mysqli Query is not returning any result -

i seem having trouble getting mysqli return result query. code is:

$db_conn = get_database(); //function returns static mysqli object reference  if($result = $db_conn->query("select city                                  state                                 name='ca' ")) {   $row = $result->fetch_object();   $city= $row->city;   $result->close(); } else {   echo $db_conn->error; } 

when echo contents of city variable, contains nothing.

1. check get_database() make sure proper database selected
2. the column state in clause same table name, state. change name instead if can.
