> We create two cubes in one project. We want to join the two query (querying
> data from two cube) together.
> But we got the error :
> null while executing SQL: "with a as ( select part_dt,sum(price) amount from
> kylin_sales group by part_dt ), b as (select part_dt,count(price) cn from
> kylin_sales group by part_dt) select * from a join b on a.part_dt= b.part_dt
> LIMIT 50000"
> The example for learn_kylin as following.
> We can get data using query select * from a , select * from b . But when
> join together,we get error.
> with a as (
> select part_dt,sum(price) amount
> from kylin_sales
> group by part_dt ),
> b as (select part_dt,count(price) cn
> from kylin_sales
> group by part_dt)
> --select * from a
> --select * from b
> select * from a
> join b on a.part_dt= b.part_dt
