SQL语句执行顺序及MySQL中limit的用法

.

 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
