mysql order by .. limit.. 笔记

当数据库中数据都为0的时候 使用order by  limit start limt sql语句时候  注意

 order by   limit 0,10 与 order by limit 10,10会出现重复数据,新版的mysql会有这个问题

the differences in that between MariaDB 5.5.50 and 10.1 

加上 id就能够避免这个问题

You do not specify which ten first rows you want to obtain. As there are a lot of rows for which published equals 0 MariaDB is free to choose some of them. If you want a specific order try:

SELECT advert_id, published, id FROM vacancies ORDER BY published asc, id LIMIT 10;
