Sql server 需要在Sql server中进行简单查询

我的标准：

我有一个分销商（父表），他有许多零售商（子表）。我需要你的姓

i、 e

我的问题是：

select distName,  
       count(retailerName) as TotalRetailer,  
       max(retailerName) as lastPosted,  
       max(lastjoinRetail) as lastJoindate 
from distributor d
  right outer join retailer r on d.distNo = r.retailNo
                             and r.status = 0 
                             and d.status = 0
group by distName.....

我不是最后加入的“零售商名称”

---

可能不匹配的列名

基于您的问题，我创建了一些示例表，并能够获得请求的输出。看看这是否有帮助

DECLARE @distributor TABLE 
  ( 
     id INT,NAME VARCHAR(100) 
  ) 

INSERT INTO @distributor 
VALUES      (1,'D1'), 
            (2,'D2') 

DECLARE @retailer TABLE 
  ( 
     id INT,NAME VARCHAR(100),distid INT,joindate DATE 
  ) 

INSERT INTO @retailer 
VALUES      (1,'R1',1,'08/01/2016'), 
            (2,'R2',1,'08/02/2016'), 
            (3,'R3',1,'08/03/2016'), 
            (4,'R4',2,'08/01/2016') 

SELECT DISTINCT a.NAME,First_value(b.NAME) 
                         OVER( 
                           partition BY a.id 
                           ORDER BY b.joindate DESC ) last_retail_name, 
                First_value(b.joindate) 
                                OVER( 
                                  partition BY a.id 
                                  ORDER BY b.joindate DESC ) last_retail_date 
FROM   @distributor a 
       INNER JOIN @retailer b 
               ON a.id = b.distid

谢谢我的查询回复，这里我有一个问题，我得到的显示只有分销商谁有零售商。如果分销商没有零售商，则不会显示这些记录？？？…将“内部联接”更改为“左联接”，以获得即使没有零售商的分销商也愿意答复我的查询，返回的错误，其中子查询返回了多个查询？。。。。
