MySQL错误“在/*100,3),%)AS`Percentage`FROM INFORMATION_SCHEMA.PROFILING附近使用正确语法”
原标题:MySQL Error "right syntax to use near /*100,3), % ) AS `Percentage` FROM INFORMATION_SCHEMA.PROFILING"

在尝试对一个大表执行查询后,我出现了一个奇怪的错误:

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 /*100,3), % ) AS Percentage FROM INFORMATION_SCHEMA.PROFILING WHERE QUERY_ID= at line 1

这是什么意思?

EDIT==这是查询

update cities w, states s set w.region_id = s.id 
where s.code = w.region and w.country_id = s.country_id 

城市表约有300万个条目,州表约有6000个条目

作为记录,我使用mysql客户端Navicat执行了这个查询。

问题回答

SQL支持C样式注释:

/* ... */

因此,看起来/*100,3被解释为注释的开头,而该注释正在破坏SQL其余部分的语法。
