> Time interval for window aggregations in SQL is wrongly translated if
> specified with YEAR_MONTH resolution
> ----------------------------------------------------------------------------------------------------------
>
> Key: FLINK-11017
> URL: https://issues.apache.org/jira/browse/FLINK-11017
> Project: Flink
> Issue Type: Bug
> Components: Table API & SQL
> Affects Versions: 1.6.2, 1.7.0
> Reporter: Dawid Wysakowicz
> Assignee: Dawid Wysakowicz
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.6.3, 1.8.0, 1.7.1
>
>
> If a time interval was specified with {{YEAR TO MONTH}} resolution like e.g.:
> {code}
> SELECT *
> FROM Mytable
> GROUP BY
> TUMBLE(rowtime, INTERVAL '1-2' YEAR TO MONTH)
> {code}
> it will be wrongly translated to 14 milliseconds window. We should allow for
> only DAY TO SECOND resolution.
