[jira] [Created] (CALCITE-631) JdbcJoin to support Non-EquiJoin

Ng Jiunn Jye created CALCITE-631:
------------------------------------

             Summary: JdbcJoin to support Non-EquiJoin
                 Key: CALCITE-631
                 URL: https://issues.apache.org/jira/browse/CALCITE-631
             Project: Calcite
          Issue Type: Improvement
            Reporter: Ng Jiunn Jye
            Assignee: Julian Hyde


Currently, the JdbcJoin only support EquiJoin. ie select * from tab1 inner join tab2 on tab1.col1=tab2.col2

NonEqui join are not supported in JdbcJoin, thus resulting execution plan which uses EnumerationJoin and EnumerableCalc for joining and not pushing the join down to remote database.
