Question

我在Oracle db中有以下查询：

select 1 AS NOT_OK,
CASE WHEN
    PPLP_NAME='PPL_CH_INVOICE' THEN
    CASE WHEN 
    ( to_char(START_TIME, 'dd')<='06' and to_char(START_TIME, 'dd')=to_char(END_TIME, 'dd') )
    THEN 1 ELSE 0 END
ELSE
    CASE WHEN
    ( to_char(START_TIME, 'dd')='01' and to_char(END_TIME, 'dd')='01' ) 
    THEN 1 ELSE 0 END
END
AS STATUS, 
PPLP_NAME,SUCCESSFUL_ROWS,START_TIME,END_TIME from GENERAL_STATISTICS.PPLP_LOAD_GENSTAT2

例如，这个输出：

           NOT_OK STATUS PPLP_NAME SUCCESSFUL_ROWS START_TIME       END_TIME
                1   0   PPL_INVOICE 11598133    27/3/2013 12:34:59 PM   27/3/2013 1:23:07  PM

如何在上面的select语句中创建两个额外的列，一个作为状态的总和，另一个作为not_ok的总和？

提前感谢！

据我所知，我认为你可以试试：

SELECT B.* 
, SUM(B.NOT_OK) OVER (PARTITION BY TO_CHAR(START_TIME,'MM') ) AS TOT_NOT_OK
, SUM(B.STATUS) OVER (PARTITION BY TO_CHAR(START_TIME,'MM')) AS TOT_STATUS
FROM (
    SELECT 1 AS NOT_OK,
        CASE WHEN PPLP_NAME='PPL_CH_INVOICE' THEN
             CASE WHEN (to_char(START_TIME, 'dd')<='06' and to_char(START_TIME, 'dd')=to_char(END_TIME, 'dd') )
                  THEN 1 
                  ELSE 0 END
        ELSE CASE WHEN ( to_char(START_TIME, 'dd')='01' and to_char(END_TIME, 'dd')='01' ) 
                  THEN 1 
                  ELSE 0 END
        END
        AS STATUS, 
        PPLP_NAME,
        SUCCESSFUL_ROWS,
        START_TIME,END_TIME 
    FROM GENERAL_STATISTICS.PPLP_LOAD_GENSTAT2
    ) B

oracle sum列作为现有表中的新列
