我在使用基本查询时遇到问题,我的临时表有一个主键和一个名为server {

的列。
我要连接到另一个包含3列的表:
PropertyID1
查询在PropertyID, SalePrice, SaleDate
和PropertyID1
上联接,我要获取的是匹配PropertyID
的最新迭代,因为每个ID可以有10个以上的匹配项,而我仅需要最新记录,列PropertyID
用于选择所需的记录。
所以最初的查询是
SaleDate
返回哪个
CREATE TABLE ##RPP_CHECK
(
ID INT IDENTITY(1,1) PRIMARY KEY,
PropertyID1 VARCHAR(255) NULL
);
INSERT INTO ##IDCHECK
VALUES (41572498), (41484495), (41590235), (41611406)
SELECT
ID, ##IDCHECK.PropertyID1, PropertyID, SalePrice, SaleDate
FROM
##IDCHECK
LEFT JOIN
[ODS].[RS1] ON [ODS].[RS1].[PropertyID] = ##IDCHECK.PropertyID1
ORDER BY
ID
我需要它退货的是
ID PropertyID1 PropertyID SalePrice SaleDate
--------------------------------------------------
1 41572498 41572498 0.0 01-01-2011
1 41572498 41572498 0.0 01-01-2012
1 41572498 41572498 1000 01-01-2018
2 41484495 41484495 1200 01-02-2018
3 41590235 41590235 2000 01-03-2018
3 41590235 41590235 0.0 01-01-1999
4 41611406 41611406 5000 01-10-2018
我尝试查看此处发布的一些答案,但它们似乎不太合适,我敢肯定这是一个ID PropertyID1 PropertyID SalePrice SaleDate
------------------------------------------------
1 41572498 41572498 1000 01-01-2018
2 41484495 41484495 1200 01-02-2018
3 41590235 41590235 2000 01-03-2018
4 41611406 41611406 5000 01-10-2018
问题,还是一个分组,但不是100%肯定如此高兴您可以提供的任何提示。

答案 0 :(得分:1)
一个选项使用ROW_NUMBER
:
SELECT ID, PropertyID1, PropertyID, SalePrice, SaleDate
FROM
(
SELECT ID, t1.PropertyID1, PropertyID, SalePrice, SaleDate,
ROW_NUMBER() OVER (PARTITION BY PropertyID ORDER BY SaleDate DESC) rn
FROM IDCHECK t1
LEFT JOIN [ODS].[RS1] t2
ON t2.PropertyID = t1.PropertyID1
) t
WHERE rn = 1;
答案 1 :(得分:1)
APPLY
通常具有最佳性能:
SELECT ic.*, r.*
FROM ##IDCHECK ic OUTER APPLY
(SELECT TOP (1) r.*
FROM [ODS].[RS1] r
WHERE r.[PropertyID] = ic.PropertyID1
ORDER BY r.SaleDate DESC
) r;
答案 2 :(得分:0)
Use MAX built in function and GROUPBY built in function in JOIN and achieve your
result
BEGIN TRAN
CREATE TABLE #Test ( ID INT , PropertyID1 VARCHAR(100) , PropertyID
VARCHAR(100) , SalePrice DECIMAL(12,2) , SaleDate DATETIME )
INSERT INTO #Test ( ID , PropertyID1 , PropertyID , SalePrice , SaleDate)
SELECT 1,'41572498','41572498',0.0,CONVERT(DATETIME,'01-01-2011',103) UNION ALL
SELECT 1,'41572498','41572498',0.0,CONVERT(DATETIME,'01-01-2012',103) UNION ALL
SELECT 1,'41572498','41572498',1000,CONVERT(DATETIME,'01-01-2018',103) UNION ALL
SELECT 2,'41484495','41484495',1200,CONVERT(DATETIME,'01-02-2018',103) UNION ALL
SELECT 3,'41590235','41590235',2000,CONVERT(DATETIME,'01-03-2018',103) UNION ALL
SELECT 3,'41590235','41590235',0.0,CONVERT(DATETIME,'01-01-1999',103) UNION ALL
SELECT 4,'41611406','41611406',5000,CONVERT(DATETIME,'01-10-2018',103)
SELECT ID , PropertyID1 , PropertyID , SalePrice , SaleDate
FROM #Test
JOIN

SELECT PropertyID _PropertyID , PropertyID1 _PropertyID1 , MAX(SaleDate)
_SaleDate

GROUP BY PropertyID,PropertyID1
