如何将以下查询转换为codeigniter查询

Question

所以这是我想要转换为codeigniter的以下查询：

$q = "DELETE FROM  group_info, contacts

USING group_info INNER JOIN contacts 

WHERE group_info.gid = '$gid'

AND contacts.gid = group_info.gid";

Answer 1

我认为你不能用Query Builder正确实现这一目标

相反 - 我建议如下

$this->db->query("DELETE FROM  group_info, contacts USING group_info INNER JOIN contacts WHERE group_info.gid = ? AND contacts.gid = group_info.gid", array($gid));

在这种情况下，您将通过绑定受到保护
