在 ORACLE SQL 中组合两个 SQL 查询以给出两个列

Question

我需要将两组不同的查询合并到两个不同的列中。

持续时间

select 
  sum(duration),
  pps.person_id
from 
    anc_per_abs_entries apae,
    anc_absence_types_vl abs,
    per_periods_of_service pps,
    anc_absence_type_reasons_f abtype,
    anc_absence_reasons_f_tl ab_reason

where 1=1
  AND (To_Char(apae.start_date  ,'YYYY-MM-DD') Between to_date(To_Char(:From_Date,'YYYY-MM-DD'),'YYYY-MM-DD') And to_date(To_Char(:To_Date,'YYYY-MM-DD'),'YYYY-MM-DD') )
  AND apae.APPROVAL_STATUS_CD = 'APPROVED'
  AND apae.ABSENCE_STATUS_CD = 'SUBMITTED'
  and abs.name like  'Paid Personal Leave' 
  AND apae.period_of_service_id = pps.period_of_service_id
  AND apae.absence_type_id = abs.absence_type_id
  AND abtype.absence_type_id = abs.absence_type_id
  AND ab_reason.absence_reason_id = abtype.absence_reason_id
  AND apae.absence_type_reason_id = abtype.absence_type_reason_id
  AND pps.person_id = papf.person_id  
group by pps.person_id

测量

select sum(measure)
from
    time_track rec ,
    time_type rec_type,
    per_all_people_f papf
where 1=1
  AND rec_type.tm_bldg_blk_version = rec.tm_rec_version
  AND rec.tm_rec_type IN ( 'RANGE', 'MEASURE' )
  AND (to_date(To_Char(rec.START_TIME,'YYYY-MM-DD'),'YYYY-MM-DD') Between to_date(To_Char(:From_Date,'YYYY-MM-DD'),'YYYY-MM-DD') And to_date(To_Char(:To_Date,'YYYY-MM-DD'),'YYYY-MM-DD') )
  and papf.person_id = rec.person_id

from_date 和 to_date 是参数，这两个查询应该形成我的结果集的两个不同列。我的预期结果是 -

person_number                      duration                                 measure
73636                               10                                       8

即持续时间来自查询 1，测量来自查询 2。如果我在一个查询中用作 2 个子查询，这两个查询需要计算并且会受到影响或被操纵。 例如，因为带薪事假的持续时间为 2020 年 1 月 1 日，但它没有“度量”，但仍会出现在结果输出中。

如何将这两者结合起来，在两个不同的列中形成结果输出

QUERY 1 QUERY 2 person_id

常用链接是 person_id。在子查询中使用时，由于日期范围内可能有多个值，因此会在子查询中给出多于 1 行的错误。

Answer 1

假设您显示的查询按照您的描述工作，那么以下虽然不漂亮，但应该可以解决问题。

SELECT T1.PERSONID, T1.DURATION, T2.MEASURE
FROM
(select 
  sum(duration) AS DURATION,
  pps.person_id AS PERSONID
from 
    anc_per_abs_entries apae,
    anc_absence_types_vl abs,
    per_periods_of_service pps,
    anc_absence_type_reasons_f abtype,
    anc_absence_reasons_f_tl ab_reason

where 1=1
  AND (To_Char(apae.start_date  ,'YYYY-MM-DD') Between to_date(To_Char(:From_Date,'YYYY-MM-DD'),'YYYY-MM-DD') And to_date(To_Char(:To_Date,'YYYY-MM-DD'),'YYYY-MM-DD') )
  AND apae.APPROVAL_STATUS_CD = 'APPROVED'
  AND apae.ABSENCE_STATUS_CD = 'SUBMITTED'
  and abs.name like  'Paid Personal Leave' 
  AND apae.period_of_service_id = pps.period_of_service_id
  AND apae.absence_type_id = abs.absence_type_id
  AND abtype.absence_type_id = abs.absence_type_id
  AND ab_reason.absence_reason_id = abtype.absence_reason_id
  AND apae.absence_type_reason_id = abtype.absence_type_reason_id
  AND pps.person_id = papf.person_id  
group by pps.person_id) T1
JOIN
(select 
   rec.person_id AS PERSONID
   sum(measure) AS MEASURE
from
    time_track rec ,
    time_type rec_type,
    per_all_people_f papf
where 1=1
  AND rec_type.tm_bldg_blk_version = rec.tm_rec_version
  AND rec.tm_rec_type IN ( 'RANGE', 'MEASURE' )
  AND (to_date(To_Char(rec.START_TIME,'YYYY-MM-DD'),'YYYY-MM-DD') Between to_date(To_Char(:From_Date,'YYYY-MM-DD'),'YYYY-MM-DD') And to_date(To_Char(:To_Date,'YYYY-MM-DD'),'YYYY-MM-DD') )
  and papf.person_id = rec.person_id) T2
ON T1.PERSONID = T2.PERSONID

顺便说一句：条件1=1 可以从两个子选择中删除。在这种情况下它实际上什么都不做。
