Question

我有这样的显示错误1292截断不正确的DOUBLE值这是我在代码点火器模型中的删除操作功能代码

public function delete_marks($s_id){
           $this->db->where_not_in('student_id', $s_id);
           return  $this->db->delete('student_marks');
       }

及其显示错误

错误号码：1292
  截断不正确的DOUBLE值：＆＃39; 305,304＆＃39;
  DELETE FROM student_marks WHERE student_id NOT IN（＆＃39; 305,304＆＃39;）

因为此部分'305,304'单个配额' '自动添加所以它显示1292错误我该怎么解决？

Answer 1

看起来你的$s_id是字符串。在CI中，where_not_in或where_in您必须传递数组。

public function delete_marks($s_id){
    $s_id = explode(",", $s_id);
    $this->db->where_not_in('student_id', $s_id);
    return  $this->db->delete('student_marks');
}

Answer 2

在where_not_in中你必须传递数组。

public function delete_marks($s_id){
    $this->db->where_not_in('student_id',explode(',', $s_id));
    return  $this->db->delete('student_marks');
}

错误号：1292在我的SQL错误中截断了错误的DOUBLE值
