クエリが実行に1分掛かり、応答時間を短縮する必要があります

Question

このクエリでは576レコードしか提供されていません。テーブルにはレコードが多すぎます。誰かがこのクエリを最適化して時間を短縮するのを助けてくれますか？あなたのクエリを改善するための

は

SELECT lov.stored_value, lov.displayed_value 
    FROM ms_qs_list_of_values_t lov, ms_qs_lov_names nam 
WHERE lov.lov_id=nam.lov_id 
    AND nam.lov_name='MS_QSM_Init_Questionnaire_Type' 

SELECT lov.stored_value, lov.displayed_value 
    FROM ms_qs_list_of_values_t lov 
    join ms_qs_lov_names nam on lov.lov_id=nam.lov_id 
where nam.lov_name='MS_QSM_Init_Questionnaire_Type' 

のチェックこれはあなたの実行時間を短縮である下のように参加し追加します。そうでない場合は、戻り値がより多くの時間を消費する関数（MS_APPS_SECURITY_PKG.CHECK_OBJECT_ACCESS、ms_qsm_rpt_util.get_url）である可能性があります。また、クエリのパフォーマンスを確認するための関数定義を指定してください。
