写的顺序：select ... from... where.... group by... having... order by.. 执行顺序：from... where...group by... having.... select ... order by...
MYSQL中：
写的顺序：select ... from... where.... group by... having... order by.. limit [offset,] (rows) 执行顺序：from... where...group by... having.... select ... order by... limit
limit限制查询的结果序号
limit off, n: 从off偏移取n个数据
limit n: 取前n个数据，相当于limit 0, n
