SQL Sub-Abfrage Fehler

Question

Ich denke, es gibt ein Problem mit dem A2-Set, wo ich nur Restart_case = Y, aber ich bin mir nicht sicher, bitte helfen Sie. Ich erhalte diesen Fehler: Ein unerwartetes Token "WHERE" wurde nach "_ID) AS Max_DateBegin" gefunden. Erwarteten Token können ... Danke

SELECT A2.* FROM 
(SELECT A1.*, min(BeginDate) OVER (PARTITION BY Per_ID) AS Min_BeginDate, 
MAX(BeginDate) OVER (PARTITION BY Per_ID) AS Max_BeginDate 
WHERE RestartCase = 'Y' 
From) A2 
(SELECT distinct C.Per_ID, P.DOB, C.BeginDate, C.EndDate, C.RestartCase, P.per_type 
FROM CaseSum C LEFT JOIN PERSON p on C.ID_PRSN = P.ID_PRSN) A1 
WHERE per_Type = 1 AND BeginDate <= '9/30/2017' AND (EndDate >= '10/01/2017' OR EndDate IS NULL) 
ORDER BY A1.Per_ID 

Answer 1

Ich glaube, das ist das, was Sie wollen (oder so ähnlich):

SELECT A2.* FROM (SELECT A1.*, MIN(BeginDate) OVER (PARTITION BY Per_ID) AS Min_BeginDate, MAX(BeginDate) OVER (PARTITION BY Per_ID) AS Max_BeginDate FROM (SELECT DISTINCT C.Per_ID, P.DOB, C.BeginDate, C.EndDate, C.RestartCase, P.per_type FROM CaseSum C LEFT JOIN PERSON P on C.ID_PRSN = P.ID_PRSN WHERE P.per_Type = 1 AND C.BeginDate <= '9/30/2017' AND (C.EndDate >= '10/01/2017' OR C.EndDate IS NULL) ) A1 WHERE A1.RestartCase = 'Y' ORDER BY A1.Per_ID ) A2

Answer 2

Betrachten sie ein bedingtes CASE Inline-Aggregat in Ihrer Fensterfunktion Kombinieren beider Versuchsergebnissätze:

SELECT DISTINCT C.Per_ID, P.DOB, C.BeginDate, C.EndDate, C.RestartCase, P.per_type, 
       MIN(CASE WHEN C.RestartCase = 'Y' THEN C.BeginDate END) 
           OVER (PARTITION BY C.Per_ID) AS Min_BeginDate, 
       MAX(CASE WHEN C.RestartCase = 'Y' THEN C.BeginDate END) 
           OVER (PARTITION BY C.Per_ID) AS Max_BeginDate  
FROM CaseSum C 
LEFT JOIN PERSON P on C.ID_PRSN = P.ID_PRSN 
WHERE P.per_Type = 1 AND C.BeginDate <= '9/30/2017' 
    AND (C.EndDate >= '10/01/2017' OR C.EndDate IS NULL) 
ORDER BY C.Per_ID
