Window clause improvements

See original GitHub issue

Two edge cases are not parsed well:

SELECT SUM(x) OVER (PARTITION BY a ORDER BY d ROWS 1 PRECEDING)

and

SELECT SUM(x) OVER (PARTITION BY a ORDER BY date ROWS BETWEEN 1 PRECEDING 1 FOLLOWING)

The first will transpile assuming BETWEEN, the second throws parse error because date is parsed as keyword instead of column name.

order by date desc works but not order by date row

Already did that on my side. Thanks for helping with the workaround. Also managed to find the minimal case producing wrong output for you (in case you need it):

select * from a order by date desc limit 1

this is interpreted as

SELECT * FROM a ORDER BY CAST(desc AS DATE) LIMIT 1
