求一查询语句，谢谢。
表a，有字段email、num，现在要求：
查到供货量（num）超过5000的所有人（email）的供货总量？
请问一下，能否用一条sql语句就返回结果？？
不知道大家明白我的意思没有？
[解决办法]
select email,sum(num) from 表A group by email having sum(num)! <5000
[解决办法]
select 供货总量=(select sum(num) from a where email=c.email) from a c where c.num > 5000
[解决办法]
select email、sum(num) 供货总量
from 表a
group by email
having sum(num) > 5000
[解决办法]
select emial,sum(num) from a group by email having num> 5000
[解决办法]
select email, sum(num) num into #1 from t group by email having sum(num)> 5000
select sum(num) from #1
