mysql - select top 与 limit的区别在哪里？

Question

比如，我们想查询结果集的最面的两条信息，比如persion表的头两条记录：

SELECT TOP 2 * FROM Persons

也可以使用limit:

select * from   Persons limit 0,2

请问这两个有什么区别，谁更好一点呢？？？？？？？？

我擦！！
MYSQL没有SELECT TOP的语法！！！
白问了，奶奶的

Answer 1

This is how it is used in different databases:
1. Select top sql usage supported in access/ms sql server;
2. The supported sql usage in mysql/oracle is select...limit;
There is no difference between the two in terms of usage. It’s just that the application platform is different.

Answer 2

mysql> SELECT TOP 2 * FROM ac_article_img;
    ERROR 1064 (42000): You have an error in your SQL syntax; check the manual       that corresponds to your MySQL server version for the right syntax to use 
    near '2 * FROM ac_article_img' at line 1

Which version of Mysql are you using? It seems that this query is not supported after 5.0.
