将我的sql查询转换为活动记录查询codeigniter

Question

SELECT * FROM cdr WHERE (Circle LIKE '%D%' OR CLI LIKE '%D%' OR Operator LIKE '%D%') AND Dept = 'Sale'

我只想像 $this->db->like('Circle','%D%') 一样，部门带有 'and'。

Answer 1

您应该阅读 codeigniter 文档，这是一个简单的文档：

$this->db->where("(Circle LIKE '%D%' OR CLI LIKE '%D%' OR Operator LIKE '%D%')")
         ->where("dept", "Sale");
$query = $this->db->get("cdr");

Answer 2

只需将关联数组提供给

or_like()

并用

group_start()

和

group_end()

将这些条件封装在括号中。

return $this->db
    ->group_start()
        ->or_like(['Circle' => 'D', 'CLI' => 'D', 'Operator' => 'D'])
    ->group_end()
    ->get_where('cdr', ['Dept' => 'Sale'])
    ->result();

如果需要，

or_like()

可以更干燥：

->or_like(array_fill_keys(['Circle', 'CLI', 'Operator'], 'D'))

渲染的 SQL：

SELECT *
FROM `cdr`
WHERE (
`Circle` LIKE '%D%' ESCAPE '!'
OR  `CLI` LIKE '%D%' ESCAPE '!'
OR  `Operator` LIKE '%D%' ESCAPE '!'
)
AND `Dept` = 'Sale'
