以下のように3つのテーブルがあります。

CREATE TABLE USER_STATUS ("UID" varchar2(7), "STAT_ID" varchar2(11)) ;
INSERT ALL 
    INTO USER_STATUS ("UID", "STAT_ID") VALUES ('UID_001', 'STAT_ID_001')

これを確認してください-> Oracle SQL Fiddle

テーブルは Oracle DB に作成されます。渡されたユーザーの UID に基づいて、以下のようにコアとステータスを取得する必要があります。

期待される結果を表示するには、ここをクリックしてください

これまでのところ、結果を取得しようとしましたが、結合できません。

SELECT STLK.STAT_CODE, STLK.STATUS FROM STATUS_LKUP STLK WHERE STLK.STAT_ID IN (SELECT USRST.STAT_ID FROM USER_STATUS USRST WHERE USRST.UID = 'UID_001');

助けてください。

参考：これは宿題ではありません。実際の表は複雑で、説明をわかりやすくするために変換しただけです。

前もって感謝します。

このバージョンのクエリは次のように機能します。

SELECT STLK.STAT_CODE, STLK.STATUS
FROM STATUS_LKUP STLK
WHERE STLK.STAT_ID IN (SELECT USRST.STAT_ID
                       FROM USER_STATUS USRST
                       WHERE USRST."UID" = 'UID_001'
                      );

UIDは、Oracle の予約語 (こちらを参照) であるため、二重引用符が必要です。
