Sql server SQL Server分组依据仅显示第一个匹配项

我有下表，想分组

[name]             [phone]
doniking           081222222222
doni               081222222222
Bambang Gentholet  081111111111
Bambang            081111111111

我想得到这个结果：

[name]             [phone]
doniking           081222222222
Bambang Gentholet  081111111111

试试这个

SELECT [name],[phone] 
FROM (
      SELECT *,Row_Number() Over (Partition By phone Order By (Select Null)) AS RN
      FROM Table1
      ) AS T
Where RN = 1
OFFSET n ROWS

SELECT name, 
   phone 
FROM  (SELECT *, 
          Row_number() 
            OVER( 
              partition BY phone 
              ORDER BY name) row_num -- or you can have order by (select null)
   FROM   table1) t 
WHERE  row_num = 1 

您可以用自定义值替换n

试试这个

SELECT MAX(name), phone  FROM <TableName> group by phone

逐个电话从通话组中选择MAX（姓名）

编辑：用于偏移

SELECT MAX(name), phone  FROM <TableName> group by phone
order by phone offset 10 rows 
FETCH NEXT 5 ROWS ONLY;

逐个电话从通话组中选择MAX（姓名）
电话订购偏移量10行
只取下5行；

有关更多详细信息。

请尝试此选项

SELECT [name],[phone] 
FROM (
      SELECT *,Row_Number() Over (Partition By phone Order By (Select Null)) AS RN
      FROM Table1
      ) AS T
Where RN = 1
OFFSET n ROWS

SELECT name, 
   phone 
FROM  (SELECT *, 
          Row_number() 
            OVER( 
              partition BY phone 
              ORDER BY name) row_num -- or you can have order by (select null)
   FROM   table1) t 
WHERE  row_num = 1

如果我添加一个列类型日期，如何基于最新日期获取名称？如何将偏移量应用于该查询？检查我的更新答案忘了说我正在使用SQL2005如何将偏移量应用于该查询？应用偏移量是什么意思？你能详细说明你要找的是什么吗？我要把需要限制和偏移的结果分页。不幸的是，我的SQL2005不支持OFFSET关键字。因此，您希望仅对最终结果应用限制和偏移量，还是在筛选出重复项之前应用限制和偏移量？如何将偏移量应用于该查询？
