> Add 'as' method for OverWindowWithOrderBy in Java API
> -----------------------------------------------------

> Key: FLINK-10676
> URL: https://issues.apache.org/jira/browse/FLINK-10676
> Project: Flink
> Issue Type: Improvement
> Components: Table API & SQL
> Affects Versions: 1.7.0
> Reporter: sunjincheng
> Assignee: Chesnay Schepler
> Priority: Major
> Fix For: 1.7.0
>
>
> The preceding clause of OVER Window in the traditional database is optional.
> The default is UNBOUNDED. So we can add the "as" method to
> OverWindowWithOrderBy. This way OVERWindow is written more easily. e.g.:
> {code:java}
> .window(Over partitionBy 'c orderBy 'proctime preceding UNBOUNDED_ROW as
> 'w){code}
> Can be simplified as follows:
> {code:java}
> .window(Over partitionBy 'c orderBy 'proctime as 'w){code}
> What do you think?
