Sean Hsuan-Yi Chu commented on CALCITE-800:
-------------------------------------------
In SqlValidatorTest.testWindowClause, we have a positive test case :
"window w as (order by rank() over (order by sal))"
Is this window is invalid? We tried a similar thing is postgres:
{code}
postgres=# select rank() over(order by row_number() over(order by XXX)) from
YYY;
ERROR: window functions are not allowed in window definitions
{code}
Is it alright to remove that test case ? Otherwise, our patch will always break
that one.
> Window function defined within another window function should be blocked at
> validation
