CodeIgniter使用this-＆gt; db-＆gt;查询分页

Question

如何在$ this-＆gt; db-＆gt; query（）方法中使用codeigniter？

如果我使用活动记录类，我会这样做：

$query = $this->db->get('tb_cash_transaction',$num,$offset);
$this->db->order_by("CURRENCY_ID", "asc"); 

现在我正在使用$ this-＆gt; db-＆gt; query（）

$query = "SELECT * FROM tb_cash_transaction, tb_currency, tb_user where tb_cash_transaction.CURRENCY_ID=tb_currency.CURRENCY_ID and tb_cash_transaction.USER_ID=tb_user.USER_ID and TYPE='cash_out'";   
$query = $this->db->query($query);

如何实施？谢谢。

尝试使用这个..

$query = "SELECT * FROM tb_cash_transaction, tb_currency, tb_user where tb_cash_transaction.CURRENCY_ID=tb_currency.CURRENCY_ID and tb_cash_transaction.USER_ID=tb_user.USER_ID and TYPE='cash_out' order by CURRENCY_ID asc LIMIT $offset , $num";
$query = $this->db->query($query);

希望这会有帮助。

谢谢！
