你在转义你的 '\' 吗？参见 http://dev.mysql.com/doc/refman/4.1/en/string-literals.html

Answer 2

试试这个活动记录：

$data = array(
         "announcement_title" => "test1",
         "announcement_desc"  => "some description",
         "announcement_date"  => "2015-01-05"

);

$this->db->update("announcement_detail",$data);
$this->db->where("announcement_id",101);
