Postgres, multiple databases, no result?

#1
[eluser]3rdear[/eluser]
Hi,

I have what appears to be a rather odd problem. All database connections and queries are correct, but I'm not actually get result data. Please see below:

Code:
public function getEntities($entityManager)
  {
    
    // $entityManager string which determines which database to connect to

    $emdb=$this->load->database($entityManager,TRUE);
    $sql="SELECT * FROM tblmarketsource";
    $entities=$emdb->query($sql);  
    $this->setEntities($entities);
    
      
  }

Now, if we do a var_dump() on $emdb, we get the following, which looks like a perfectly valid database connection ... and it IS:

Code:
object(CI_DB_postgre_driver)#20 (71) {
  ["dbdriver"]=>
  string(7) "postgre"
  ["_escape_char"]=>
  string(1) """
  ["_like_escape_str"]=>
  string(13) " ESCAPE '%s' "
  ["_like_escape_chr"]=>
  string(1) "!"

  bool(true)
  ["_trans_depth"]=>
  int(0)
  ["_trans_status"]=>

  ["stmt_id"]=>
  NULL
  ["curs_id"]=>
  NULL
  ["limit_used"]=>
  NULL
  ["stricton"]=>
  bool(false)
}

Continuing on, if we do a var_dump() on $entities, that is where the weirdness begins ...

Code:
object(CI_DB_postgre_result)#22 (8) {
  ["conn_id"]=>
  resource(20) of type (pgsql link persistent)
  ["result_id"]=>
  resource(21) of type (pgsql result)
  ["result_array"]=>
  array(0) {
  }
  ["result_object"]=>
  array(0) {
  }
  ["custom_result_object"]=>
  array(0) {
  }
  ["current_row"]=>
  int(0)
  ["num_rows"]=>
  int(27)
  ["row_data"]=>
  NULL
}

Notice how the element "num_rows" = 27 but there appears to be no "result object", no "custom_result_object" and no "row_data". Incidentally, in the above case, the actual query if run in pgAdmin does return 27 rows full of data, but CI doesn't return squat. Also, if we do a var_dump on $entities->num_fields() we actually get an integer of 5, which is also correct. So why would ALL the "result" elements be empty and why would "row_data" be NULL? Please help me out here.
