php - 从纯 php 进行查询以查询 CodeIgniter

Question

我已经学习了 CodeIgniter，但我在将纯 php 查询转换为查询 CodeIgniter 时遇到困难，如何修复 CodeIgniter 中的查询？

此查询使用 Codeigniter

public function get_kal($id) {
    $query = $this->db
            ->select('myname as name')
            ->from('mytable')
            ->where('myname', $id)
            ->like('%%%s%%')
            ->order_by('myname','ASC');
            ->get("q");

    $arr = array();

    $rs = mysql_query($query);

    while($obj = mysql_fetch_object($rs))
    {
        $arr[] = $obj;
    }

    echo json_encode($arr);     
}

此查询使用纯 php

public function get_name($id) { 
        $query = sprintf("SELECT  myname as name from mytable WHERE myname LIKE '%%%s%%' ORDER BY myname DESC ", mysql_real_escape_string($_GET["q"]));
        $arr = array();
        $rs = mysql_query($query);

        while($obj = mysql_fetch_object($rs))
        {
            $arr[] = $obj;
        }

        echo json_encode($arr); 
    }

Answer 1

可以直接使用

进行查询

$this->db->query('YOUR QUERY HERE');

您还可以构建查询

$query = $this->db
            ->select('myname as name')
            ->from('mytable')
            ->like('myname', $this->input->get('q', TRUE))
            ->order_by('myname','ASC');
