缺少右括號

Question

我只是用SQL開始，當我試圖運行，下面這段代碼，它顯示錯誤「缺少右括號」

SELECT a.author 
FROM DLESSA.DBLP_AUTHOR a 
WHERE a.authorId IN 
(SELECT ea.authorId 
FROM DLESSA.DBLP_ENTITY_ARTICLE ea 
WHERE ea.entityId IN 
(SELECT ea.entityId  
FROM DBLP_ENTITY_ARTICLE ea JOIN DBLP_ENTITY_AUTHOR ea1 ON ea1.entityId=ea.entityId ea1 JOIN DLESSA.DBLP_AUTHOR a ON a.authorId=ea1.authorId ea 
WHERE ea.Author LIKE 'Tongs%')); 

有人可以告訴我在哪裏我的錯誤是什麼？數百萬的感謝！

格式揭示了原因：

SELECT a.author 
FROM DLESSA.DBLP_AUTHOR a 
WHERE a.authorId IN 
    (SELECT ea.authorId 
     FROM DLESSA.DBLP_ENTITY_ARTICLE ea 
     WHERE ea.entityId IN 
      (SELECT ea.entityId  
      FROM DBLP_ENTITY_ARTICLE ea    
       JOIN DBLP_ENTITY_AUTHOR ea1 
       ON ea1.entityId=ea.entityId ea1  --- aliases? 
       JOIN DLESSA.DBLP_AUTHOR a 
       ON a.authorId=ea1.authorId ea    --- here? 
      WHERE ea.Author LIKE 'Tongs%' 
     ) 
    );
