mysql - 选择sql表的最后3行

Question

我想选择一个 sql 表的最后 3 行。我知道我应该使用SELECT * FROM table ORDER BY DESC LIMIT 3，但是这段代码的问题是它从最后选择行。例如，它选择 30，然后是 29，然后是 28。但是，我需要这些格式：28, 29, 30. 有什么建议吗？

Answer 1

尝试这个：

SELECT * FROM (
  SELECT * FROM reset ORDER BY id DESC LIMIT 3
) as r ORDER BY id

Answer 2

我希望这对您的问题有所帮助

select * from
(
select *  from reset 
order by id DESC LIMIT 3
 ) t
order by id ASC 

Answer 3

尝试这样的事情： -

  SELECT * FROM reset 
  WHERE username = '$table' ORDER BY id  ASC LIMIT (FOUND_ROWS() - 3), 3

Answer 4

尝试

Select * from (SELECT * FROM Table_name ORDER BY Column_name DESC limit 0,3) as alias ORDER BY Column_name ASC;

Answer 5

怎么样：

select * from (select * from table order by x desc limit 3) order by x;

Answer 6

它将帮助您提供最新的 3 行数据，如果您想获取前 3 行，那么ASC而不是DESC.

select distinct column_name from  Table order by column_name desc limit 3;
