sql 不会 请教大神帮忙

可以这样:

select * from 购物信息 where 购物人 in 
            (select 购物人 from 购物信息 group by 购物人 having count(*) >= 2);

说明：用了一个子查询，表名及字段名请再核实。

如果对您有帮助，请采纳答案好吗，谢谢！

select * from t_OrderInfo where fUserCode in (select fUserCode from t_OrderInfo group by fUserCode having count(fUserCode) >= 2);
