             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.
