> Interval join with equal time attributes is not recognized
> ----------------------------------------------------------
>
> Key: FLINK-19792
> URL: https://issues.apache.org/jira/browse/FLINK-19792
> Project: Flink
> Issue Type: Bug
> Components: Table SQL / Planner
> Reporter: Timo Walther
> Priority: Minor
> Labels: auto-deprioritized-major, pull-request-available
>
> A user reported that interval joins with equal time attribute predicate are
> not recognized, instead a regular inner join is used:
> For example:
> {code}
> table1 = table_env.from_path("table1")
> table2 = table_env.from_path("table2")
> print(table1.join(table2).where("ts = ts2 && id = id2").select("id, ts")
> {code}
> The documentation clearly states that this should be supported:
> {code}
> For example, the following predicates are valid interval join conditions:
> ltime === rtime
> ltime >= rtime && ltime < rtime + 10.minutes
> {code}
