Question

如何在Codeigniter的活动记录SQL查询中使用圆括号符号？例如如何完成

SELECT * FROM `shops` WHERE (`shopid` = '10' OR `shopid` = '11') AND `shopid` <> '18'

Answer 1

$where="(`shopid` = '10' OR `shopid` = '11')";

$ this-＆gt; db-＆gt; where（$ where，NULL，FALSE）;

和AND条件使用

$this->db->where('shopid <>', '18')

即

$where="(`shopid` = '10' OR `shopid` = '11')";
$this->db->where($where, NULL, FALSE);
$this->db->where('shopid <>', '18')

Answer 2

我认为你可以这样做：

$where = "(`shopid` = '10' OR `shopid` = '11')";

$this->db->where($where)  // or statement here
         ->where('shopid <>', '18') // chaining with AND
         ->get('shops');

不完全确定语法，我写的是我的头脑。如果这不起作用，我会在回家时看看它。

您可以执行以下操作：

$this->db->select('field')->from('shops')->where("(`shopid` = '10' OR `shopid` = '11'")->where("`shopid` <> '18'");
$query = $this->db->get();

您可以编写自己的子句   手动：

$ where =“name ='Joe'AND status ='boss'   OR status ='active'“;

$这 - ＆GT; DB-化合物其中（$其中）;

Answer 4

$this->db->select()
         ->from('shops')
         ->where("'(`shopid` = '10' OR `shopid` = '11')")
         ->where('shopid !=', 18);

$this->db->get()->result();

Codeigniter - 带有activerecord的括号？
