Jesus Camacho Rodriguez commented on HIVE-23868:
------------------------------------------------
[~jdere], what do you think about adding the change to
{{SelectClauseParser.g}}? Maybe something like this would work?
{code}
0 KW_PRECEDING -> ^(KW_CURRENT)
{code}
The reason I am asking is that then we will get CURRENT_ROW both through Hive
and Calcite.
> Windowing function spec: support 0 preceeding/following

> HIVE-12574 removed support for 0 PRECEDING/FOLLOWING in window function
> specifications. We can restore support for this by converting 0
> PRECEDING/FOLLOWING to CURRENT ROW in the query plan, which should be the
> same.
