如果CATEGORY_EXISTS = 0，则如何更新GT_ADD_ISBNS表，如果FINAL_DOCUMENTS不为null，则错误_mesage ='未找到类别' finalename = FINAL_DOCUMENTS，FINAL_DOCUMENTS为null然后error_mesage ='找不到文档';

SELECT  (SELECT COUNT(*)
        FROM 
        TEMP_NODE_PROPERTIES ANP,
    TEMP_NODE_PROPERTIES ANPP,
        TEMP_NODE AN
        WHERE 
      ANP.NODE_ID=AN.ID AND
    ANPP.NODE_ID=ANP.NODE_ID AND
    AN.TYPE_QNAME='asset' AND
    ANP.STRING_VALUE ='uPDF' AND ANPP.STRING_VALUE ='Entire PDF'  AND
    ANP.TYPE_QNAME='categories'  AND
        ANP.NODE_ID IN(SELECT CHILD_ID 
                  FROM TEMP_CHILD_ASSOC START WITH PARENT_ID IN(
                 SELECT CHILD_ID FROM TEMP_CHILD_ASSOC WHERE NAME in(GT.ISBN)) 
                      CONNECT BY PRIOR CHILD_ID = PARENT_ID)
    )  CATEGORY_EXISTS,
    (SELECT LISTAGG(T1.STRING_VALUE, ',') WITHIN GROUP  (ORDER BY T1.STRING_VALUE)
       FROM         TEMP_NODE_PROPERTIES T1
        WHERE   T1.TYPE_QNAME='name'  AND  (T1.STRING_VALUE LIKE '%pdf%'  AND  T1.STRING_VALUE NOT LIKE '%pod%') 
         AND  T1.NODE_ID IN (SELECT ANP.NODE_ID
        FROM 
        TEMP_NODE_PROPERTIES ANP,
    TEMP_NODE_PROPERTIES ANPP,
        TEMP_NODE AN
        WHERE 
      ANP.NODE_ID=AN.ID AND
    ANPP.NODE_ID=ANP.NODE_ID AND
    AN.TYPE_QNAME='asset' AND
    ANP.STRING_VALUE ='uPDF' AND ANPP.STRING_VALUE ='Entire PDF' AND
    ANP.TYPE_QNAME='categories'  AND
        ANP.NODE_ID IN(SELECT CHILD_ID 
                  FROM TEMP_CHILD_ASSOC START WITH PARENT_ID IN(
                 SELECT CHILD_ID FROM TEMP_CHILD_ASSOC WHERE NAME in(GT.ISBN)) 
                      CONNECT BY PRIOR CHILD_ID = PARENT_ID)))
     FINAL_DOCUMENTS
        FROM  GT_ADD_ISBNS GT;

也许是这样的事情？

UPDATE gt_add_isbns
   SET (error_message, filename) =
          (SELECT CASE
                     WHEN category_exists = 0 THEN 'category not found'
                     WHEN final_documents IS NULL THEN 'documents not found'
                  END,
                  CASE
                     WHEN final_documents IS NOT NULL THEN final_documents
                  END
             FROM (SELECT category_exists, final_documents
                     FROM (your current query goes here)));
