codeigniter按编号连接表而不是另一个表

Question

当我尝试在codeigniter中进行此连接时

$this->db->join('ticketsale','ticketsale.id = 1');

我收到此错误：未知列＆＃39; 1＆＃39;在＆＃39; on条款＆＃39;

"SELECT * FROM (`users`) JOIN `ticketsale ` ON `ticketsale `.`id` = `1` JOIN `ticketsale_.."

如何让codeigniter不要把``大约1？

Answer 1

因为在join语句中，您必须使用列名来匹配它们并加入其他查询。如果您想这样做，您应该添加Where语句。 例如：

"SELECT * FROM (`users`) JOIN `ticketsale ` ON `ticketsale `.`id` = `hereyourtable`.`hereis the column` JOIN `ticketsale_..  WHERE `ticketsale `.`id`=1"

<强>更新： 此外，在活动记录中;

 $this->db->join("ticketsale","ticketsale.id=users.column")->where("ticketsale.id"=>"1");
this query will return same as native sql query
