Zend DB Select：ORDER BY FIELD（'id'，some_array） - 怎么样？

Question

您如何在Zend框架中编写以下查询？

SELECT * FROM table_name ORDER BY FIELD(field_name, 'Small','Medium','Large');

我只需要“Order by”部分：）

谢谢！

Answer 1

这个怎么样：

      $db = Zend_Db_Table::getDefaultAdapter();

      $select = $db->select();

      $select->from('table_name')
              ->order(new Zend_Db_Expr("FIELD(field_name, 'Small','Medium','Large')"));


      var_dump($select->assemble());

结果：

string 'SELECT `table_name`.* FROM `table_name` ORDER BY FIELD(field_name, 'Small','Medium','Large')' (length=92)

Answer 2

$select->order(new Zend_Db_Expr('FIELD(field_name, 'Small','Medium','Large')'));

Answer 3

我认为你应该这样做：

$db = Zend_Db::factory( ...options... );
$select = $db->select()
 ->from(table_name)
 ->order(new Zend_Db_Expr("FIELD(field_name, 'Small','Medium','Large')")));
