Description:
JDBC adapter incorrectly pushes windowed aggregates down to HSQLDB. Queries
containing window functions fail when using HSQLDB (or any other DB that does
not support window functions) because the optimizer converts them to native SQL
with window functions which are not supported by HSQLDB. For example:
{code:sql}
select "store_id", "product_id", sum("unit_sales") unit_sales, row_number()
over (
partition by "store_id" order by sum("unit_sales") desc
) row_num
from "sales_fact_1998"
group by "store_id", "product_id"
{code}
was:
