sql limit offset 区别

select * from table limit 2,1;                 

//含义是跳过2条取1条数据，即读取第3条数据

select * from table limit 2 offset 1;  //这种更容易理解一些

//含义是从第1条（不包括）数据开始取出2条数据，limit后面跟的是2条数据，offset后面是从第1条开始读取，即读取第2,3条

先写order by再limit

SELECT article FROM table1 ORDER BY publish_date LIMIT 20

It will order first, then get the first 20. A database will also process anything in the WHERE clause before ORDER BY.
