Question

SELECT  FCR.FCR_ID,
        FCR.FCR_TITLE FCR_TITLE,
        to_char(FCR.FCR_DATE_SUB, 'fmDD Mon YYYY') DATEIN 
FROM    PMP_SCRIPT        FCR,
        PMP_SCRIPT_PART CST, 
        PMP_USER              USR,
        PMP_SCRIPT_EVENTS PST
WHERE   CST.CST_ROLE  = 'MANAGER'   and 
        CST.CST_STATUS    = 'ADDED'   and 
        CST.CST_USR_ID    = 1573752923320092       and 
        PST.PST_EVENTTYPE = 'ONREVIEW' and 
        PST.PST_FCR_ID    = CST.CST_FCR_ID     and  
        PST.PST_USR_ID    = USR.USR_ID       and   
        PST.PST_FCR_ID    = FCR.FCR_ID  
ORDER  BY FCR.FCR_DATE_CREATED;

我得到以下结果

        PAGES               TITLE                           DATEIN

但我希望得到所有独特的结果，有人可以帮助我 我已尝试使用distinct关键字，但查询提供了“not selection expression

”

Answer 1

您可以尝试使用不同的内联查询。也许这会对你有帮助。

SELECT DISTINCT A.*
FROM
  (SELECT FCR.FCR_ID,
    FCR.FCR_TITLE FCR_TITLE,
    TO_CHAR(FCR.FCR_DATE_SUB, 'fmDD Mon YYYY') DATEIN
  FROM PMP_SCRIPT FCR,
    PMP_SCRIPT_PART CST,
    PMP_USER USR,
    PMP_SCRIPT_EVENTS PST
  WHERE CST.CST_ROLE    = 'MANAGER'
  AND CST.CST_STATUS    = 'ADDED'
  AND CST.CST_USR_ID    = 1573752923320092
  AND PST.PST_EVENTTYPE = 'ONREVIEW'
  AND PST.PST_FCR_ID    = CST.CST_FCR_ID
  AND PST.PST_USR_ID    = USR.USR_ID
  AND PST.PST_FCR_ID    = FCR.FCR_ID
  ORDER BY FCR.FCR_DATE_CREATED
  )A ;

如何从下面的oracle sql查询中获得不同的结果？
