Question

想要接受以下查询并对其进行更改，以便它仅返回记录，其中每个患者（基于MRN）具有两个程序代码IN（＆＃39; 115-1＆＃39;，＆＃39; 117- 1＆＃39;，＆＃39; 311-1＆＃39;）和ProcedureCodeList =＆＃39; 119-103＆＃39;

 SELECT P.SiteID, O.ProcedureCodeList, P.MRN, PINFO.LastName, PINFO.FirstName, PINFO.[State] AS Species, PINFO.City AS Breed, O.ProcedureDescList, RF.FieldName, RF.FieldValue, R.ContentText
, R.LastSignDate

FROM ReportFinding RF

INNER JOIN Report R
ON RF.ReportID = R.ReportID
INNER JOIN [Order] O
ON R.ReportID = O.ReportID
INNER JOIN Visit V
ON O.VisitID = V.VisitID
INNER JOIN Patient P
ON P.PatientID = V.PatientID
INNER JOIN PersonalInfo PINFO
ON P.PersonalInfoID = PINFO.PersonalInfoID

WHERE
O.ProcedureCodeList IN ('115-1','117-1','119-103')

ORDER BY R.LastSignDate DESC

Answer 1

有几种方法可以解决这个问题。一种方法是创建两个子查询并将它们连接到MRN上。

SELECT a.SiteID, a.ProcedureCodeList, a.MRN, a.LastName, a.FirstName, a.Species, a.Breed, a.ProcedureDescList, a.FieldName, a.FieldValue, a.ContentText, a.LastSignDate
FROM 
(SELECT P.SiteID, O.ProcedureCodeList, P.MRN, PINFO.LastName, PINFO.FirstName, PINFO.[State] AS Species, PINFO.City AS Breed, O.ProcedureDescList, RF.FieldName, RF.FieldValue, R.ContentText, R.LastSignDate
FROM ReportFinding RF
INNER JOIN Report R ON RF.ReportID = R.ReportID
INNER JOIN [Order] O ON R.ReportID = O.ReportID
INNER JOIN Visit V ON O.VisitID = V.VisitID
INNER JOIN Patient P ON P.PatientID = V.PatientID
INNER JOIN PersonalInfo PINFO ON P.PersonalInfoID = PINFO.PersonalInfoID
WHERE O.ProcedureCodeList IN ('115-1','117-1','119-103')) as a
JOIN 
(SELECT P.MRN
FROM [Order]
INNER JOIN Visit V ON O.VisitID = V.VisitID
INNER JOIN Patient P ON P.PatientID = V.PatientID
WHERE O.ProcedureCodeList = '119-103') as b ON a.MRN = b.MRN
ORDER BY a.LastSignDate

第二个查询中不需要PersonalInfo表。我认为ReportFinding和Report也不是基于你的JOIN。这取决于这些表实际上在做什么。

另一种方法从原始查询开始，并将以下内容添加到WHERE子句中（在ORDER BY之前）：

AND P.MRN IN
(SELECT P.MRN
FROM [Order]
INNER JOIN Visit V ON O.VisitID = V.VisitID
INNER JOIN Patient P ON P.PatientID = V.PatientID
WHERE O.ProcedureCodeList = '119-103')

我会看两个解决方案的执行计划，以了解在这种情况下哪个更好。

嵌套查询WHERE过程代码IN和AND
