>             Project: Calcite
>          Issue Type: Bug
>          Components: jdbc-adapter
>    Affects Versions: 1.15.0

>            Priority: Major
>
> Queries containing window functions fail when using HSQLDB (or any other DB that does not support window functions) because optimiser 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}
