如果需要每个Name的最后一行，那么可以按Name为每个行组提供行号，并按Id降序排序。

查询

SELECT t1.Id, 
       t1.Name, 
       t1.Other_Columns
FROM 
(
     SELECT Id, 
            Name, 
            Other_Columns,
    (
        CASE Name WHEN @curA 
        THEN @curRow := @curRow + 1 
        ELSE @curRow := 1 AND @curA := Name END 
    ) + 1 AS rn 
    FROM messages t, 
    (SELECT @curRow := 0, @curA := '') r 
    ORDER BY Name,Id DESC 
)t1
WHERE t1.rn = 1
ORDER BY t1.Id;

SQL小提琴

从MySQL 8.0.14开始，也可以使用横向派生表来实现:

SELECT t.*
FROM messages t
JOIN LATERAL (
  SELECT name, MAX(id) AS id 
  FROM messages t1
  WHERE t.name = t1.name
  GROUP BY name
) trn ON t.name = trn.name AND t.id = trn.id

db < >小提琴

解决方案由子查询小提琴链接

select * from messages where id in
(select max(id) from messages group by Name)

解决方案通过连接条件小提琴链接

select m1.* from messages m1 
left outer join messages m2 
on ( m1.id<m2.id and m1.name=m2.name )
where m2.id is null

这篇文章的原因是只给小提琴链接。 在其他答案中已经提供了相同的SQL。

希望以下Oracle查询能有所帮助:

WITH Temp_table AS
(
    Select id, name, othercolumns, ROW_NUMBER() over (PARTITION BY name ORDER BY ID 
    desc)as rank from messages
)
Select id, name,othercolumns from Temp_table where rank=1

根据您的问题，下面的查询将很好地工作。

SELECT M1.* 
FROM MESSAGES M1,
(
 SELECT SUBSTR(Others_data,1,2),MAX(Others_data) AS Max_Others_data
 FROM MESSAGES
 GROUP BY 1
) M2
WHERE M1.Others_data = M2.Max_Others_data
ORDER BY Others_data;

SELECT 
  column1,
  column2 
FROM
  table_name 
WHERE id IN 
  (SELECT 
    MAX(id) 
  FROM
    table_name 
  GROUP BY column1) 
ORDER BY column1 ;
