你需要在一段时间内做到这一点 having 子句，或在外部查询中。不能像您正在尝试的那样在where子句中使用聚合函数。
试试这个：

SELECT a.comunity, sum(b.cont_woman),sum(b.cont_men)
FROM cont_per_comunity.states_per_comunities a
JOIN cont_per_comunity.cont_per_state b
ON a.state = b.state
GROUP BY a.comunity
having sum(b.cont_woman) >= sum(b.cont_men)

或者

select * from (
    SELECT a.comunity, sum(b.cont_woman) as cont_woman
    ,sum(b.cont_men) as cont_men
    FROM cont_per_comunity.states_per_comunities a
    JOIN cont_per_comunity.cont_per_state b
    ON a.state = b.state
    GROUP BY a.comunity ) t
    where cont_woman >= cont_men
