select sum(points) as total_points from soMetable where total_points > 25 group by username
我无法在where子句中引用total_points,因为我收到以下错误：ERROR：列“total_points”不存在.在这种情况下,我在where子句中没有重写sum(points)的问题,但是我想要一些做上面所说的方法.

SELECT t.* FROM ( SELECT SUM(points) AS total_points FROM soMetable GROUP BY username ) t WHERE total_points > 25
编辑：忘记别名子查询.
