Cara menambah satu lagi lajur pada jadual yang sama sambil mengekalkan kumpulan mengikut klausa

Question

Senarai lajur dalam Jadual 1: Plan_ID, Claim_id, Patient_id, B_OR_G

Senarai lajur dalam Jadual 2: Ojid, Shapland

select distinct a.Plan_ID
       , a.Total_Claims
       , Total_Patients
       ,  b.PERIOD
       , b.ORGID,a.B_OR_G
FROM (Select distinct Plan_ID
             , count(distinct Claim_id) as Total_Claims
             , count(distinct Patient_id)  as Total_Patients 
      from table1 group by 1) a
JOIN (select *
             , row_number() over (partition by ORGID,SHAPLANID order by PROCESSINGDATE desc) as rank
      from table2 qualify rank = 1) b
ON LTRIM(a.PLAN_ID, '0') = b.SHAPLANID

Dalam pertanyaan di atas, saya ingin mengekstrak satu lagi lajur bernama "B_or_G" daripada jadual1 (iaitu a) tanpa mengganggu kumpulan mengikut klausa kerana ia perlu mengikut keperluan kami.

Adakah cara yang lebih baik untuk melakukan ini? Terima kasih! !

Answer 1

Saya rasa anda boleh menggunakan ANY_VALUE(B_or_G)

Contohnya:

select distinct a.Plan_ID
       , a.Total_Claims
       , Total_Patients
       ,  b.PERIOD
       , b.ORGID,a.B_OR_G
FROM (Select distinct Plan_ID
             , count(distinct Claim_id) as Total_Claims
             , count(distinct Patient_id)  as Total_Patients 
             , ANY_VALUE(B_OR_G)
      from table1 group by 1) a
JOIN (select *
             , row_number() over (partition by ORGID,SHAPLANID order by PROCESSINGDATE desc) as rank
      from table2 qualify rank = 1) b
ON LTRIM(a.PLAN_ID, '0') = b.SHAPLANID
