检索仅链接到该会话的数据

Retrieve data only linked to that session

我需要获取 UserID_Staff 与会话 StaffID

匹配的数据

我的查询

$this->db->select('Report_Comments.Comments, Report_Comments.Comment_Date staff.Staff_Username')
                ->from('Report_Comments')
                ->join('staff', 'Report_Comments.UserID_Staff = staff.StaffID')
                ->where('UserID_Staff', $this->session->userdata("StaffID"));
            return $result = $this->db->get();

知道为什么会出现此错误,以及如何更改我的查询吗?

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '.`Staff_Username` FROM `Report_Comments` JOIN `staff` ON `Report_Comments`.`User' at line 1

SELECT `Report_Comments`.`Comments`, `Report_Comments`.`Comment_Date` `staff`.`Staff_Username` FROM `Report_Comments` JOIN `staff` ON `Report_Comments`.`UserID_Staff` = `staff`.`StaffID` WHERE `UserID_Staff` = '3'

$this->db->select('Report_Comments.Comments, Report_Comments.Comment_Date ,staff.Staff_Username')

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

您在 Report_Comments.Comment_Date , staff.Staff_Username

附近错过了 ','
