### Describe the bug It looks the current range frame defines as <img width="807" alt="Image" src="https://github.com/user-attachments/assets/0fae7808-890c-48d3-b88b-ff19df19a50e" /> but the range should defines as: from [MySQL spec](https://dev.mysql.com/doc/refman/8.0/en/window-functions-frames.html) ``` frame_extent: {frame_start | frame_between} frame_between: BETWEEN frame_start AND frame_end frame_start, frame_end: { CURRENT ROW | UNBOUNDED PRECEDING | UNBOUNDED FOLLOWING | expr PRECEDING | expr FOLLOWING } ``` for example, if we aggregate on a date window( the last month's measure), we can sql like ```sql select so.shop_id, date_trunc('month', so.order_date) as month, count(distinct si.sale_order_id) as cnt_orders, sum(quantity) as quantities, sum(amount) as amounts, first_value( count(distinct si.sale_order_id) ) over w as l1 from sale_items si left join sale_orders so on so.sale_order_id = si.sale_order_id group by so.shop_id, date_trunc('month', so.order_date) window w as ( partition by so.shop_id order by date_trunc('month', so.order_date) range between interval 31 days PRECEDING and interval 1 days preceding ) order by so.shop_id, date_trunc('month', so.order_date); ``` ### To Reproduce _No response_ ### Expected behavior _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
