sql - 发生数据库错误错误号：1054

Question

我尝试使用 sql 为我的 CI 进行选项删除，但为什么它仍然错误？

错误警告：

A Database Error Occurred

Error Number: 1054

Unknown column 'sip' in 'where clause'

select * from t_label where label = sip

Filename: E:\web\rbt.new\system\database\DB_driver.php

Line Number: 330

代码：

function hapus($id_user){
            if($this->session->userdata('username')==TRUE) {
                $name = $this->db->query("select USER_NAME from t_user where USER_ID = $id_user")->row();
                $id_label = $this->db->query("select * from t_label where label = $name->USER_NAME")->row();
                $this->db->query("delete from t_label, t_publisher where t_label.id_label = t_publisher.id_label and t_label.id_label = $id_label->id_label");
                $this->db->delete('t_user', array('USER_ID' => $id_user));
                redirect("registrasi/reg");
            }
        }

我的代码有什么问题？这里真的需要帮助

您需要引用字符串。尝试这个：

$id_label = $this->db->query("select * from t_label where label = '" . $name->USER_NAME . "'")->row();
