Verwenden von Auswählen für mehrere Spalten

Question

Gibt es eine effizientere Möglichkeit, diese Abfrage durchzuführen? Es läuft, dauert aber ca. 6 Minuten. Ich glaube, die Multiple-Select-Anweisungen erzeugen die Verzögerung. Running von ihnen selbst die Rückkehr ein Ergebnis in < 1 Sek.

Answer 1

Ich gehe davon aus, dass Sie 1: M Beziehung zwischen MEMB_COMPANY und PROV_COMPANY und 1: M Beziehung zwischen PROV_COMPANY und PROV_ADDINFO. Dann sollte es möglich sein, Ihre Unterabfragen mit GROUP BY und conditional aggregation neu zu schreiben. So etwas wie die folgende Abfrage. Ich habe nur die ersten beiden Unterabfragen umgeschrieben. Ich denke, die Idee ist klar.

SELECT 
    x.HPCODE as [Health Plan] 
    ,x.HPFROMDT as [Eff Date] 
    ,x.MEMBID AS [ID #] 
    ,x.LASTNM as [Mbr L Name] 
    ,x.FIRSTNM as [Mbr F Name] 
    ,x.BIRTH as DOB 
    ,datediff(year,birth,getdate()) as Age 
    ,x.PCP as [Prov ID#] 
    ,Y.LASTNAME as [Prov L Name] 
    ,Y.FIRSTNAME as [Prov F Name] 
    ,PA.PHONE as [Provider Phone] 
    ,max(CASE WHEN left(cd.PROCCODE,5) in ('G0402','G0438','G0439') and Year(cm.SERVICEDATEFROM) = Year(Getdate()) THEN cd.FROMDATESVC END) 
    ,max(CASE WHEN left(cd.PROCCODE,5) in ('G0402','G0438','G0439') or Right(cd.PROCCODE,5) in ('99490','99487','99489') and Year(cm.SERVICEDATEFROM) = Year(Getdate()) THEN cd.FROMDATESVC END) 
    -- the subsequent conditions follows 
FROM [dbo].[MEMB_COMPANY] X 
LEFT JOIN [dbo].[PROV_COMPANY] Y ON X.PCP = Y.PROVID 
Join [dbo].[PROV_ADDINFO] PA ON Y.PROV_MPI_NO = PA.PROV_MPI_NO and (PA.EDI_DEFAULT = 1) 
LEFT JOIN [dbo].[Claim_Masters] cm ON cm.MEMBID = x.MEMBID 
LEFT JOIN [dbo].[Claim_Details] cd on cm.claimno = cd.claimno 
WHERE (isnull(x.OPTHRUDT, '') = '' or x.OPTHRUDT > GETDATE()) and X.HPCODE = 'CHPS' 
GROUP BY x.MEMBID, x.HPCODE ,x.HPFROMDT, x.LASTNM, x.FIRSTNM, x.BIRTH, x.PCP, Y.LASTNAME, Y.FIRSTNAME, PA.PHONE 

ich das Gefühl, dass Ihre Anfrage als auch beschleunigt werden könnte, wenn man die left(cd.PROCCODE,5) und right(cd.PROCCODE,5) Werte in der Tabelle vorauszuberechnen.

Answer 2

Subqueries sind oft langsam ... Sie sollten versuchen, sie mit einer Syntax wie zu vermeiden:

SELECT 
     x.HPCODE as [Health Plan] 
     ,x.HPFROMDT as [Eff Date] 
     ,x.MEMBID AS [ID #] 
     ,x.LASTNM as [Mbr L Name] 
     ,x.FIRSTNM as [Mbr F Name] 
     ,x.BIRTH as DOB 
     ,datediff(year,birth,getdate()) as Age 
     ,x.PCP as [Prov ID#] 
     ,Y.LASTNAME as [Prov L Name] 
     ,Y.FIRSTNAME as [Prov F Name] 
     ,PA.PHONE as [Provider Phone] 
     ,MAX(CASE WHEN left(cd.PROCCODE,5) in ('G0402','G0438','G0439') THEN cd.FROMDATESVC ELSE NULL END) as [AWV] 
     ,MAX(CASE WHEN left(cd.PROCCODE,5) in ('G0402','G0438','G0439') or Right(cd.PROCCODE,5) in ('99490','99487','99489') THEN cd.FROMDATESVC ELSE NULL END) as [CCM] 
     ,MAX(CASE WHEN Right(cd.PROCCODE,5) in ('99495','99496') THEN cd.FROMDATESVC ELSE NULL END) as [TCM] 
     ,MAX(CASE WHEN Right(cd.PROCCODE,5) in ('99211','99212','99213','99214','99215','99201','99202','99203','99204','99205') THEN cd.FROMDATESVC ELSE NULL END) as [Office] 
     ,MAX(CASE WHEN Right(cd.PROCCODE,5) = '1170F' THEN cd.FROMDATESVC ELSE NULL END) as [FUNC]

     ,MAX(CASE WHEN Right(cd.PROCCODE,5) in ('0521F','1125F','1126F') THEN cd.FROMDATESVC ELSE NULL END) as [PAIN] 
     ,MAX(CASE WHEN Right(cd.PROCCODE,5) in ('99605','99606','1160F','1111F','1159F') THEN cd.FROMDATESVC ELSE NULL END) as [MTM]
