[jira] [Created] (FLINK-11017) Time interval for window
aggregations in SQL is wrongly translated if specified with YEAR_MONTH
resolution
Dawid Wysakowicz created FLINK-11017:
----------------------------------------
Summary: 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
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.
