在 ANY 中查找与 PostgreSQL 中的条件匹配的最新项目

Question

这些天我一直在尝试解决这个问题，但尚未找到解决方案。这是我当前的查询：

SELECT e.id, case when 7768 = any(e.class) then 'INP' else 'OUT' END AS type,
    cc.display   AS typedesc,  ccc.display, 
    cccc.display AS status3 ,  pat.id       AS patid, 
    pat.gender              ,  pat.birthdate,
    l.alias      AS room_ref,  l.name       AS room_name,
    l.id         AS room_id ,  ll.id        AS bed_id,
    ll.alias     AS bed_name,  l.partof,
    concat(hn.prefix,' ',hn.given,' ',hn.family), e.plannedenddate
FROM ecosystem.encounter e
LEFT JOIN ecosystem.codeableconcept cc   ON cc.id   = any(e.class)
LEFT JOIN ecosystem.codeableconcept ccc  ON ccc.id  = e.priority
LEFT JOIN ecosystem.codeableconcept cccc ON cccc.id = e.subjectstatus
LEFT JOIN ecosystem.patient pat ON pat.id = (e.subject->>'identifier')::int
LEFT JOIN ecosystem.practitioner prac 
  ON prac.id = (SELECT (zz->'actor'->>'identifier')::int 
                FROM jsonb_array_elements(e.participant) zz 
                WHERE zz->'type'->>'code' = 'ATND')
LEFT JOIN ecosystem.humanname hn ON hn.id = any(prac.name)
LEFT JOIN (SELECT * FROM ecosystem.locations WHERE form = 7930) l 
  ON l.id = (e.location[jsonb_array_length(e.location)-1]->>'identifier')::int
LEFT JOIN (SELECT * FROM ecosystem.locations WHERE form = 7931) ll 
  ON ll.id = (e.location[jsonb_array_length(e.location)-1]->>'identifier')::int
WHERE EXISTS (
  SELECT FROM jsonb_array_elements(e.participant) AS papi
  WHERE jsonb_typeof(papi->'actor') = 'object' 
    AND (papi->'actor'->>'identifier') = '27'
    AND (papi->'actor'->>'reference') LIKE 'Organization/%')
AND e.status in ('in-progress','on-hold','discharged')
AND 3 = any(l.partof)
AND EXISTS (
  SELECT FROM jsonb_array_elements(participant) pa
  WHERE pa->'type'->>'code' = 'ATND' 
    AND pa->'actor'->>'identifier' ='99')

这是我从旧查询中尝试查询患者在医院内的位置。之前我们只需要房间，因此：

left join (select * from ecosystem.locations where form = 7930) l 
on l.id = (e.location[jsonb_array_length(e.location)-1]->>'identifier')::int

有效，因为 e.location 中的最后一个元素是患者的房间。现在情况并非如此，因为它可以是一个房间或一张床，不知何故，我需要过滤

any

并匹配与左侧子查询的任何

id

匹配的最新项目。

Answer 1

尝试下面，我引入了一个

LATERAL

连接来动态处理

e.location JSONB

数组中的最后一个元素可以是房间或床的情况。此连接首先识别

e.location

中的最新位置，然后根据该位置是被识别为房间

(form 7930)

还是床

(form 7931)

有条件地连接到位置表。
