获取最新10条记录的sql语句如下:
select * from some_table order by id desc limit 0,10
- SELECT * FROM table LIMIT [offset,] rows | rows OFFSET offset
LIMIT 子句可以被用于强制 SELECT 语句返回指定的记录数。MySQL LIMIT 接受一个或两个数字参数。参数必须是一个整数常量。如果给定两个参数,第一个参数指定第一个返回记录行的偏移量,第二个参数指定返回记录行的最大数目。初始记录行的偏移量是 0(而不是 1): 为了与 PostgreSQL 兼容,MySQL 也支持句法: LIMIT # OFFSET #。
- MySQL> SELECT * FROM table LIMIT 5,10;
检索记录行 6-15
为了检索从某一个偏移量到记录集的结束所有的记录行,可以指定第二个参数为 -1:
- MySQL> SELECT * FROM table LIMIT 95,-1;
检索记录行 96-last.
如果只给定一个参数,它表示返回最大的记录行数目:
- MySQL> SELECT * FROM table LIMIT 5;
检索前 5 个记录行。换句话说,LIMIT n 等价于 MySQL LIMIT 0,n。
实例如下:
