-----------------------------------

             Summary: 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
             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?
