{code}
{code}
select Orders.Country, Orders.ProductCategory,count(1) from Orders join (select
Orders.Country, count(1) CountryOrderCount from Orders where
to_date(Orders.PlacedDate) > '2015-01-01' group by Orders.Country order by
CountryOrderCount DESC LIMIT 5) Top5Countries on Top5Countries.Country =
Orders.Country where to_date(Orders.PlacedDate) > '2015-01-01' group by
Orders.Country,Orders.ProductCategory;
{code}
The temporary workaround is to add explicit alias for the table Orders
{code}
select o.Country, o.ProductCategory,count(1) from Orders o join (select
r.Country, count(1) CountryOrderCount from Orders r where to_date(r.PlacedDate)
> '2015-01-01' group by r.Country order by CountryOrderCount DESC LIMIT 5)
Top5Countries on Top5Countries.Country = o.Country where to_date(o.PlacedDate)
> '2015-01-01' group by o.Country,o.ProductCategory;
{code}
However this change not only affects self joins, it also seems to affect union
queries as well, like the below query which was again working before(commit
9a151ce) got broken
{code}
select Orders.Country,null,count(1) OrderCount from Orders group by
Orders.Country,null
union all
select null,Orders.ProductCategory,count(1) OrderCount from Orders group by
null, Orders.ProductCategory
{code}
also fails with a Analysis exception.
The workaround is to add different aliases for the tables.
