使用ORDER BY和UNION进行ORACLE查询

提问于

我有以下查询，效果很好！

唯一的问题是我需要DESC Order中的结果集，并且我在查询结尾处附加的以下ORDER BY子句会生成以下Oracle错误：

ORA-00933：SQL命令未正确结束00933. 00000 - "SQL command not properly ended" *原因：
*动作：行错误：46列：54

这是查询 . 同样，此查询有效 . 只是当我添加以下行时：

FINAL_SEARCH order by FINAL_SEARCH.DOC_HDR_ID desc

一切都破裂了 .

有任何想法吗？我相信我的ALIAS与它有关，但我可能是错的 .

查询 -

Select * from ( select DISTINCT(DOC_HDR.DOC_HDR_ID), 
    DOC_HDR.INITR_PRNCPL_ID, 
    DOC_HDR.DOC_HDR_STAT_CD, 
    DOC_HDR.CRTE_DT, 
    DOC_HDR.TTL, 
    DOC_HDR.APP_DOC_STAT, 
    DOC1.DOC_TYP_NM, 
    DOC1.LBL, DOC1.DOC_HDLR_URL, 
    DOC1.ACTV_IND  
    from KREW_DOC_TYP_T DOC1, KREW_DOC_HDR_T DOC_HDR   
    where DOC_HDR.INITR_PRNCPL_ID IN ( '10000000001' )  and 
        ( DOC1.DOC_TYP_NM =  'PO' or  
          DOC1.DOC_TYP_NM = 'POA' or  
          DOC1.DOC_TYP_NM = 'POC' or  
          DOC1.DOC_TYP_NM= 'POPH' or  
          DOC1.DOC_TYP_NM ='PORH' or  
          DOC1.DOC_TYP_NM = 'POR' or  
          DOC1.DOC_TYP_NM = 'PORT' or  
          DOC1.DOC_TYP_NM = 'POSP' or 
          DOC1.DOC_TYP_NM = 'POV') and 
          DOC_HDR.DOC_HDR_STAT_CD!= 'I' and  
          DOC_HDR.DOC_TYP_ID = DOC1.DOC_TYP_ID ) 

    UNION 

    Select DISTINCT DOC_HDR.DOC_HDR_ID, 
            DOC_HDR.INITR_PRNCPL_ID, 
            DOC_HDR.DOC_HDR_STAT_CD, 
            DOC_HDR.CRTE_DT, 
            DOC_HDR.TTL, 
            DOC_HDR.APP_DOC_STAT, 
            DOC1.DOC_TYP_NM, 
            DOC1.LBL, 
            DOC1.DOC_HDLR_URL, 
            DOC1.ACTV_IND 
     FROM KREW_DOC_TYP_T DOC1, 
   KREW_DOC_HDR_T DOC_HDR 
   WHERE DOC1.DOC_TYP_NM = 'PO' AND CAST(DOC_HDR.DOC_HDR_ID AS VARCHAR(14)) = ANY ( 
      Select PPT.FDOC_NBR 
      FROM PUR_PO_T PPT, PL_PURCHASE_LOG_PO_T PPL 
      WHERE PPT.AP_PUR_DOC_LNK_ID = ANY ( 
         Select PRT.AP_PUR_DOC_LNK_ID 
         FROM PUR_REQS_T PRT, 
              KREW_DOC_HDR_T DOC_HDR 
         WHERE CAST(DOC_HDR.DOC_HDR_ID AS VARCHAR(14)) = PRT.FDOC_NBR AND 
           DOC_HDR.INITR_PRNCPL_ID IN ( '10000000001' ) )) FINAL_SEARCH order by FINAL_SEARCH.DOC_HDR_ID desc;

更新 - 我删除了ALIAS并在两个查询之后放置了'ORDER BY'语句，它在SQL Developer中工作;但是，当我通过使用Java生成此查询的Web应用程序执行此查询时，我得到一个关于INVALID SYMBOL的ORACLE ERROR . 无效符号是一个分号，用于终止第一个ORDER BY语句 . 它在SQL Developer中不起作用，但显然当我执行通过Web App生成的相同语句时 - 它失败了 .

    您需要计算括号 - 要联合的两个查询应该在一个括号中 - 然后您的别名和SELECT * FROM将起作用 .

    SELECT *
    FROM ( (SELECT DISTINCT (doc_hdr.doc_hdr_id),

    我认为你正在使用一个额外的支架'）'

    首先删除条件中的最后一个括号，然后尝试 . 最后再添加一个括号 ) FINAL_SEARCH order by

    你忘记了一些括号：

    去掉 ”;”用于填充数据集/数据表的Web应用程序中的符号 .

    您还可以按块顺序使用列顺序作为别名，例如：
