Question

表1

id mobile uid uniqueid   time

1   9999   1232    200100   10/6/15

2   9999   1232    200100   11/5/14

3   8888   1232    200100   18/4/16

4   9999   1232    200100   07/7/15

5   9999   1232    200100   4/11/16

表2

id   Qid    account

1    200100   123456

2    200100   123456

3    200100   123456

我只想根据手机号码重复数据

我使用像

这样的查询

SELECT R.Id,R.MobileNo,R.UId,R.UniqueId,R.Time, 
ISNULL(C.account,'Not Present'), 
FROM table1 R LEFT JOIN table2 C
 ON R.uniqueId=C.QId where 
 and R.deleteStatus='Y' and C.accountNos ='123456'

欲望输出

mobile  uid    uniqueid  time    account
9999    1232    200100  4/11/16  123456
8888    1232    200100  18/4/16  123456

我尝试了sql server中的所有东西但是无法得到欲望输出请帮帮我!!!!!

Answer 1

请试试这个：

with cte as (
    SELECT 
         R.Id,
         R.MobileNo,
         R.UId,
         R.UniqueId,
         R.Time, 
         ISNULL(C.account,'Not Present'),
         Row_Number() Over(Partition by R.MobileNo order by [time] Desc) as RN
    FROM table1 R 
    LEFT JOIN table2 C
      ON R.uniqueId=C.QId 
    where 
         R.deleteStatus='Y' and C.accountNos ='123456' 
 )
   Select * from cte
   Where rn=1

Answer 2

CREATE TABLE #TABLE1
(


ID INT, MOBILE INT, UID INT, UNIQUEID INT,  TIME DATE
)


INSERT INTO #TABLE1 VALUES(1,9999,1232,200100,'6-10-15')
INSERT INTO #TABLE1 VALUES(2,9999,1232,200100,'5-11-14')
INSERT INTO #TABLE1 VALUES(3,8888,1232,200100,'4-18-16')
INSERT INTO #TABLE1 VALUES(4,9999,1232,200100,'7-7-15')
INSERT INTO #TABLE1 VALUES(5,9999,1232,200100,'11-4-16')


SELECT * FROM #TABLE1

CREATE TABLE #B
(
ID INT,   QID INT,   ACCOUNT INT)
INSERT INTO #B VALUES

(1,200100,123456),
(2,200100,123456),
(3,200100,123456)


;WITH CTE AS
(

SELECT DISTINCT T1.MOBILE,UID,UNIQUEID,TIME,ACCOUNT, 
ROW_NUMBER() OVER(PARTITION BY MOBILE ORDER BY [TIME] DESC) AS RN
FROM #TABLE1 T1 JOIN #B T2 ON T1.ID=T1.ID
AND T1.UNIQUEID=T2.QID 

)
SELECT  MOBILE,UID,UNIQUEID,TIME,ACCOUNT

FROM CTE
WHERE RN=1

Answer 3

试试这个：这将提供表格中的最新数据

SELECT R.Id,R.MobileNo,R.UId,R.UniqueId,MAX(R.Time),ISNULL(C.account,'Not Present'), 
FROM table1 R 
LEFT JOIN table2 C ON R.uniqueId=C.QId AND C.accountNos ='123456'   
WHERE R.deleteStatus='Y' 
GROUP BY R.Id,R.MobileNo,R.UId,R.UniqueId,ISNULL(C.account,'Not Present')

sql server来自连接上的两个表的不同行
