sql报错

Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: 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 'while id=1' at line 3

好久不打sql命令，刚刚学mybatis，就发现了这个错误，最后发现sql语句的条件update tb_user
        set name=#{name},sex=#{sex},age=#{age}
        while id=#{id}错了，是where，基础要好好巩固啊。
