Question

我有以下SQL：

UPDATE msh_leads ml
LEFT JOIN msh_leads_disposition_log dl
ON ml.id = dl.lead_id
SET ml.assigned_to = null
WHERE ((dl.disposition_id != 6 AND dl.disposition_id != 3) OR (dl.disposition_id IS NULL))
AND (ml.assigned_to = ? AND ml.decline = 0 AND ml.subcategory_id = ?)

创建这个有一些逻辑（根据某些情况，其中一些来来往往）所以我希望在Codeigniter（2.2）Active Record中重新创建它。我不确定如何将连接添加到更新或如何将多个复杂的where语句添加到更新。

这会帮助你。试试这个。

注意：您需要将您的值置于？，否则它会抛出错误1064

$this->db->set('ml.assigned_to', 'null');
$this->db->where('ml.assigned_to = ?');
$this->db->where('((dl.disposition_id != 6 AND dl.disposition_id != 3) OR (dl.disposition_id IS NULL))');
$this->db->where('ml.decline = 0');
$this->db->where('ml.subcategory_id = ?');
$this->db->update('msh_leads ml join msh_leads_disposition_log dl on ml.id = dl.lead_id');

Codeigniter 2.2 - 使用左连接和多个where子句的Active Record更新
