ORA-00904：带有左外部联接的无效标识符

Question

我在查询时遇到麻烦。它说：

Cookie                      ->    Alternative
Forms (Sub-flow)            ->    Alternative
    Password                ->    Required
    2FA (Sub-flow)          ->    Required
        OTP                 ->    Alternative
        SMS                 ->    Alternative

我正在尝试解决问题，但我似乎找不到问题。

ORA-00904: "KT"."urutan"."ED"."id_evaluasi": invalid identifier

请帮助我。我真的停留在这一点上。

您的comma缺少group by

 $query = $this->db->query('
        SELECT 
            ED."id_kategori",
            KT."kategori",
            ED."id_evaluasi",
            KT."urutan",
            ED."id_perspektif"
        FROM "evaluasidetails" ED
        LEFT OUTER JOIN "kategoris" KT ON KT."id_kategori" = ED."id_kategori"
        WHERE ED."id_evaluasidetail" = '.$id_evaluasi.'
        GROUP BY ED."id_perspektif", ED."id_kategori", KT."kategori", KT."urutan",  ED."id_evaluasi"
        ORDER BY KT."urutan" ASC
        ');
