mysql中limit子句标准语法为:

<code class="language-sql">SELECT * FROM table LIMIT [offset,] rows | rows OFFSET offset
</code>
Copy after login


从上面我们可以看出limit有如下几种用法:

第一种使用情况:

<code class="language-sql">select * from table limit 5</code>
Copy after login

取前五条

第二种使用情况:

<code class="language-sql">select * from table limit 0,5</code>
Copy after login

从第1-5条,这里用了一个offset参数,这个参数是从0开始计数的。如果取值为1,则表示从第2条开始。后面的5仍然是条数。

第三种使用情况:

<code class="language-sql">select * from table limit 5 OFFSET 0</code>
Copy after login

作用还是取第1-5条,只是用了OFFSET这个子句配合limit一起使用。
