golang sql like坑，急！！！

代码：and c.userName like '%数学%' 输出SQL：select ..... and c.userName like '%!数(MISSING)学%!'(MISSING) %s order by l.StartTime 报错： 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 '(MISSING) %!s(MISSING) order by l.StartTime limit 0,10 麻烦大神们帮忙看一下，是不是%要转译，其他语言都不会，GO编译出来就报错
