Codeigniter Active Record 'where_or' 分组 [英] Codeigniter Active Record 'where_or' grouping

问题描述

是否可以将 and_where/or_where/or_like... 语句分组 在一起，以免与其他 and/where 语句混合.

Is it possible to group and_where / or_where / or_like... statements together so as not to mix with other and/where statements.

会导致的结果

WHERE city = 'My City' AND state = 'My State' AND (name LIKE %name1%或名称如 %name2%)

WHERE city = 'My City' AND state = 'My State' AND (name LIKE %name1% OR name LIKE %name2%)

推荐答案

是的.$this->db->where() 允许您手动编写子句.你可以这样做:

Yes. $this->db->where() allows you to write clauses manually. You could do this:

$this->db->where('city', 'My City');
$this->db->where('state', 'My State');
$this->db->where('(name LIKE %name1% OR name LIKE %name2%)', null, false);

将第三个参数设置为 false 可防止 CodeIgniter 尝试向子句添加反引号.

Setting the third parameter for false prevents CodeIgniter from trying to add backticks to the clause.

查看 Active Record 文档.标题为 $this->db->where(); 的部分解释了可用于设置 WHERE 子句的四种方法.

Check out the Active Record documentation. The section titled $this->db->where(); explains the four methods you can use to set WHERE clauses.
