Vicențiu Ciorbaru	3dd3a5da0e	MDEV-9935: Window functions: assertion failure with empty OVER () clause ... Make window functions work with an empty over clause by forcing a sort on the first column of the current join_tab. This is a temporary fix until we get window functions to work with big tables.	2016-09-24 15:12:34 +02:00
Vicențiu Ciorbaru	23e8b508a0	MDEV-10059: Compute window functions with same sorting criteria simultaneously ... Perform only one table scan for each window function present. We do this by keeping keeping cursors for each window function frame bound and running them for each function for every row.	2016-09-09 18:32:35 +03:00
