请帮助获取办公室明智的数据行

Question

select NUM_OFC_CODE,NUM_RO_CODE, 
 case when TXT_MONTH='JAN' then 1 ELSE 0 end as JAN,
case when TXT_MONTH='FEB' then 1 ELSE 0  end as FEB,
case when TXT_MONTH='MAR' then 1  ELSE 0 end as MAR,
case when TXT_MONTH='APR' then 1 ELSE 0  end as APR,
case when TXT_MONTH='MAY' then 1 ELSE 0  end as MAY,
case when TXT_MONTH='JUN' then 1 ELSE 0 end as JUN,
case when TXT_MONTH='JUL' then 1 ELSE 0 end as JUL,
case when TXT_MONTH='AUG' then 1 ELSE 0 end as AUG,
case when TXT_MONTH='SEP' then 1 ELSE 0  end as SEP,
case when TXT_MONTH='OCT' then 1 ELSE 0  end as OCT,
case when TXT_MONTH='NOV' then 1 ELSE 0  end as NOV,
case when TXT_MONTH='DEC' then 1 ELSE 0 end as DEC 
 from LEG_OMBUDSMAN_NONMACT where
 NUM_YEAR=2019   group by NUM_OFC_CODE,TXT_MONTH,NUM_RO_CODE;

结果如下：-

NUM_OFC_CODE    NUM_RO_CODE JAN FEB MAR APR MAY JUN JUL AUG SEP OCT NOV DEC

我想要办公室数据。如果存在 8 月数据，则应显示 1，否则为 0。其他月份也是如此。但在我的查询中，单独的行显示了单独的月份。

Answer 1

基本上，您必须仅按 NUM_OFC_CODE,NUM_RO_CODE 对数据进行分组（不包括 TXT_MONTH，因为您不希望每个 TXT_MONTH 实例都有一行），然后使用 NVL(MAX(CASE WHEN TXT_MONTH='JAN' THEN 1 END), 0) as JAN 之类的东西（使用聚合函数来决定是否输入存在与否）等。

使用枢轴更容易：

-- Just some sampledata:
WITH LEG_OMBUDSMAN_NONMACT(NUM_OFC_CODE, NUM_RO_CODE, NUM_YEAR, TXT_MONTH) AS
  (SELECT 1,1,2019, 'JAN' FROM dual union ALL
  SELECT 1,1,2019, 'FEB' FROM dual)
-- Here starts the actual query:
SELECT NUM_OFC_CODE, NUM_RO_CODE
     , NVL(JAN,0) AS JAN
     , NVL(FEB,0) AS FEB
     , NVL(MAR,0) AS MAR
     , NVL(APR,0) AS APR
     , NVL(MAY,0) AS MAY
     , NVL(JUN,0) AS JUN
     , NVL(JUL,0) AS JUL
     , NVL(AUG,0) AS AUG
     , NVL(SEP,0) AS SEP
     , NVL(OCT,0) AS OCT
     , NVL(NOV,0) AS NOV
     , NVL(DEC,0) AS DEC
  FROM LEG_OMBUDSMAN_NONMACT
  pivot (MAX(1) FOR TXT_MONTH IN ('JAN' AS JAN,'FEB' AS FEB,'MAR' as MAR, 'APR' as APR, 'MAY' as MAY, 'JUN' as JUN, 'JUL' as JUL, 'AUG' as AUG, 'SEP' as SEP, 'OCT' as OCT, 'NOV' as NOV, 'DEC' as DEC ))
 WHERE NUM_YEAR=2019

Answer 2

您的查询非常好，只需要进行一些更改。

1. 从分组依据中删除 txt_month。
2. 在所有 case 语句中使用 Max。

所以你的查询应该是这样的

select NUM_OFC_CODE,
    NUM_RO_CODE, 
    Max(case when TXT_MONTH='JAN' then 1 ELSE 0 end) as JAN,
    Max(case when TXT_MONTH='FEB' then 1 ELSE 0  end) as FEB,
    Max(case when TXT_MONTH='MAR' then 1  ELSE 0 end) as MAR,
    Max(case when TXT_MONTH='APR' then 1 ELSE 0  end) as APR,
    Max(case when TXT_MONTH='MAY' then 1 ELSE 0  end) as MAY,
    Max(case when TXT_MONTH='JUN' then 1 ELSE 0 end) as JUN,
    Max(case when TXT_MONTH='JUL' then 1 ELSE 0 end) as JUL,
    Max(case when TXT_MONTH='AUG' then 1 ELSE 0 end) as AUG,
    Max(case when TXT_MONTH='SEP' then 1 ELSE 0  end) as SEP,
    Max(case when TXT_MONTH='OCT' then 1 ELSE 0  end) as OCT,
    Max(case when TXT_MONTH='NOV' then 1 ELSE 0  end) as NOV,
    Max(case when TXT_MONTH='DEC' then 1 ELSE 0 end) as DEC 
     from LEG_OMBUDSMAN_NONMACT 
    where NUM_YEAR=2019   
    group by NUM_OFC_CODE ,NUM_RO_CODE;

干杯！！
