Question

如何在fuelPHP中使用orm执行此查询：

SELECT * FROM user when a=1 and b=2 and (c=1 or d=2 or e=3)

我不知道如何实现此部分and (c=1 or d=2 or e=3)

坚持：

 $where = array()
 $where[] = array('a'=>1,'b'=>2);

 //Adding c,d,e column in $where[]
  I dont know how to combine AND and OR

     $query = Model_User::find('all', array(
                          'where' => $where
                  ));)

有没有办法实现这个目标？

先谢谢

Answer 1

您可以像这样使用where_or：

$q = Model_User::query();
$q->where('a', '=', 1);
$q->and_where('b', '=', 2);
$q->or_where_open();
  $q->where('c', '=', 1);
  $q->or_where('d', '=', 2);
  $q->or_where('e', '=', 3);
$q->or_where_close();

或者确实喜欢这个（我在选择时发现更容易阅读：

{{1}}

您也可以这种方式使用它，或者查看此链接以获得更多光线{Query builder Where - Classes FuelPHP documentation

//this should be done within the model that you wish to deal with
$query = DB::select("*");
$query->from->("user");
$query->where("a","=","1");
$query->and_where("b","=","2");
$query->where(function($query){
$query->where("c","=","1");
$query->or_where("d","=","2");
$query->or_where("e","=","3");
});
$query->execute();

你可以链，所以这更具可读性：

$q = Model_User::query()
     ->where('a', '=', 1)
     ->and_where('b', '=', 2)
     ->or_where_open()
        ->where('c', '=', 1)
        ->or_where('d', '=', 2)
        ->or_where('e', '=', 3)
   ->or_where_close();

如果要使用数据库查询来提高性能，但仍需要ORM模型对象，可以使用as_object（），请参阅http://fuelphp.com/docs/packages/orm/crud.html#/custom_sql

FuelPHP orm多个AND，OR查询
