问题描述

我想从一个有三个条件的表中选择一个Codeigniter选择查询。

I want a Codeigniter select query from a table with three conditions in .

coditionis are 
1. wrk_fld_exc = 140
2. wrk_cs_sts = Open
3. wrk_dlvrd_sts = Delivered OR wrk_cl_sts = Success

第三个条件是AND条件包含OR条件。
第一个和第二个是条件。

The third condition is an AND condition contains OR condition. First and second is And condition.

推荐答案

你可以这样编码：

       $this->db->where('wrk_fld_exc',140);
       $this->db->where('wrk_cs_sts','open');
       $where = '(wrk_dlvrd_sts="open" or wrk_cl_sts = "Success")';
       $this->db->where($where);
