Description:
For OVER SQL:
{code}
SELECT a COUNT(c) OVER (ORDER BY proctime RANGE BETWEEN INTERVAL '10' SECOND
PRECEDING AND CURRENT ROW) as cnt1 FROM MyTable
{code}
We expect plan {{DataStreamCalc(select=[a, w0$o0 AS cnt1]) }} But we get
{{DataStreamCalc(select=[a, w0$o0 AS $1]) }}. this improve only for plan check.
the functional is work well in nested queries，e.g.:
{code}
SELECT cnt1 from (SELECT a COUNT(c) OVER (ORDER BY proctime RANGE BETWEEN
INTERVAL '10' SECOND PRECEDING AND CURRENT ROW) as cnt1 FROM MyTable)
{code}
The SQL above is work well. which mentioned in
[FLINK-6760|https://issues.apache.org/jira/browse/FLINK-6760].
