表 CHECKUP(ChkNo, CaseNo, CTime, PID)

ChkNo| CaseNo| CTime                  | PID
============================================
1    | 10    | 13 Jan 2014 03:05:15 PM| 21
2    | 11    | 17 Jan 2014 04:13:25 PM| 23
3    | 10    | 29 Mar 2014 02:45:34 PM| 21

表 DIAGNOSIS(CheckupNumber, Region, Value)

ChkNo| Region| Value
=====================
1    | AAA   | CCC
1    | BBB   | AAA
1    | CCC   | CCC
2    | DDD   | HHH
3    | BBB   | BBB
3    | AAA   | BBB

表 PATIENT(PID, Name)

SQL

SELECT B.CaseNo AS CNum, B.PID AS PatientID, C.CTime AS CTime, P.Name AS Name, D.ChkNo AS CheckupNumber, MAX(D.Region+'     '+D.Value) AS Disease 
FROM BASECASE B, CHECKUP C, PATIENT P, DIAGNOSIS D 
WHERE D.ChkNo LIKE C.ChkNo AND C.CaseNo LIKE B.CaseNo AND P.PID LIKE B.PID AND C.CTime >='1 Jan 2014' AND C.CTime <'1 Jan 2015' AND (D.Region LIKE '%AAA%' OR D.Value LIKE '%AAA%') 
GROUP BY B.CaseNo, B.PID, C.CTime, P.Name, D.ChkNo 
ORDER BY C.CTime ASC

预期结果：

CaseNo| CTime                   | PID| Name| DISEASE| ChkNo
===========================================================
10    | 13 Jan 2014 03:05:15 PM | 21 | John| AAA CCC| 1

结果发生：

CaseNo| CTime                   | PID| Name| DISEASE| ChkNo
===========================================================
10    | 13 Jan 2014 03:05:15 PM | 21 | John| AAA CCC| 1
10    | 29 Mar 2014 02:45:34 PM | 21 | John| AAA BBB| 3

逻辑：
在这里，我们需要查看DIAGNOSIS的地区或价值是否为％AAA％＆＃39;，
如果我们发现地区或价值是％AAA％＆＃39;然后我们需要显示相应的（CaseNo，ChkNo，PID，Name，CTime FROM BASECASE，CHECKUP和PATIENT
但不应重复CaseNo。

选择
MAX（地区+＆＃39;＆＃39; +价值）来自 DIAGNOSIS [（地区或价值）=＆＃39;％AAA％＆＃39;]
DISTINCT（CaseNo），来自 BASECASE 的PatientID
CheckupNo，CTime来自 CHECKUP [CTime＆gt;＆＃39; 2014年1月1日＆＃39;和CTime＆lt;＆＃1; 2015年1月1日＆＃39;]
PATIENT

的姓名

如何排序此问题？

Answer 1

试试这个：

SELECT * FROM
(
    SELECT B.CaseNo AS CNum, B.PID AS PatientID, C.CTime AS CTime, P.Name AS Name, D.ChkNo AS CheckupNumber, (D.Region + '     ' + D.Value ) AS Disease, ROW_NUMBER() OVER (PARTITION BY c.caseno ORDER BY c.ChkNo) rn FROM   DIAGNOSIS D
    JOIN CHECKUP C ON D.chkno = C.ChkNo
    JOIN BASECASE B ON B.CaseNo = C.CaseNo
    JOIN PATIENT P ON B.PID = P.PID
    WHERE
         C.CTime >= '1 Jan 2014' AND C.CTime < '1 Jan 2015'
         AND (D.Region LIKE '%AAA%' OR D.Value LIKE '%AAA%')
) AS t WHERE  rn = 1

注意：您可以将条件ORDER BY c.ChkNo更改为ORDER BY c.CTime，以获得最小CTime或ORDER BY c.CTime DESC的条件，以获得最大CTime c.caseno 1}}在具有相同{{1}}。

的行中

Answer 2

试试这个:(如果不工作更新您的状态）

  SELECT B.CaseNo AS CNum, B.PID AS PatientID, C.CTime AS CTime, P.Name AS Name, D.CheckupNumber AS CheckupNumber, MAX(D.Region+'     '+D.Value) AS Disease 
FROM BASECASE B, CHECKUP C, pATIENT P, DIAGNOSIS D 
WHERE D.CheckupNumber LIKE C.ChkNo AND C.CaseNo LIKE B.CaseNo AND P.PID LIKE B.PID AND C.CTime >='1 Jan 2014' AND C.CTime <'1 Jan 2015' AND (D.Region LIKE '%AAA%' OR D.Value LIKE '%AAA%') 
GROUP BY B.CaseNo, B.PID, C.CTime, P.Name, D.CheckupNumber 
ORDER BY C.CTime ASC
