t1 = table(timestamp, sym, qty, price);

t1;

select sum(qty) as totalqty from t1 group by sym having sum(qty)>10000;

select * from t1 context by sym having count(sym)>2 and sum(qty)>10000;

select * from t1 context by sym having rank(qty)>1;

 
select * from t1 context by sym having rank(qty)>1 and sum(qty)>10000;

在select语句中，对符合having条件的记录进行计算：

select *, min(qty) from t1 context by sym having rank(qty)>1;

top语句可以与context by语句和having语句一起使用。

select top 2 * from t1 context by sym having sum(qty)>8000;
