菜鸡上路，路遇大坑，还请大神拉一把可好（SQL rank() over 函数）

SELECT *,rank() over(PARTITION BY score ORDER BY score DESC) AS rank FROM sc;

这是我的表图片和查询语句，一直报错。烦得很

1 queries executed, 0 success, 1 errors, 0 warnings
查询：select *,rank() over(PARTITION BY score ORDER BY score DESC) as rank from sc LIMIT 0, 1000
错误代码： 1064
