Question

我想为联合表做更新。但是，我对单引号有疑问。

我的CI活动记录：

UPDATE `pm_requirement_assign_pic_d pm_rapd INNER JOIN pm_activity_project pm_ap ON pm_rapd`.`RECEIVED_BY =` `pm_ap`.`NIP` SET `pm_rapd`.`STATUS` = 1 WHERE `pm_ap`.`UPL_FILENAME` = 'condition_1' AND `pm_rapd`.`ID_REQUIREMENT_ASSIGN_PIC` = 'condition_2'

这是查询：

UPDATE pm_requirement_assign_pic_d pm_rapd INNER JOIN pm_activity_project pm_ap ON pm_rapd.RECEIVED_BY = pm_ap.NIP SET `pm_rapd`.`STATUS` = 1 WHERE `pm_ap`.`UPL_FILENAME` = 'condition_1' AND `pm_rapd`.`ID_REQUIREMENT_ASSIGN_PIC` = 'condition_2'

所需的正确查询应为：

Answer 1

我确信有多种方法可以实现您想要实现的目标，但我喜欢使用CodeIgniter DB的查询绑定功能。无论何时我正在做一些不仅仅是一个简单的查询，我使用查询绑定。有关详细信息，请参阅用户指南：https://www.codeigniter.com/user_guide/database/queries.html#query-bindings

function upd_pic_hps_drtu( $i_lamp, $i_id_req )
{
    $this->db->query('
        UPDATE pm_requirement_assign_pic_d pm_rapd 
        INNER JOIN pm_activity_project pm_ap 
        ON pm_rapd.RECEIVED_BY = pm_ap.NIP 
        SET `pm_rapd`.`STATUS` = 1 
        WHERE `pm_ap`.`UPL_FILENAME` = ? 
        AND `pm_rapd`.`ID_REQUIREMENT_ASSIGN_PIC` = ?
    ', array( $i_lamp, $i_id_req ) );
}

注意我是如何使用您想要的查询，但用问号替换值，然后将数组中的值添加为查询方法的第二个参数。

我不确定，但你尝试过这样的事吗

function upd_pic_hps_drtu($i_lamp,$i_id_req)
{
    $this->db
        ->set("pm_rapd.STATUS",1)
        ->join("pm_activity_project pm_ap","pm_rapd.RECEIVED_BY = pm_ap.NIP", "inner")
        ->where("pm_ap.UPL_FILENAME", $i_lamp)
        ->where("pm_rapd.ID_REQUIREMENT_ASSIGN_PIC", $i_id_req)
        ->update("pm_requirement_assign_pic_d pm_rapd");
}

如果可行的话 - 我会这样做。

Imho查询绑定功能只应在特殊情况下使用，因为查询构建器可以简化您的查询...（除了这是一个独立于数据库的层）

如何在CI活动记录中修复此查询？
