(was: JdbcJoin does not convert Join with alwayt true/false RexNode)
> JdbcJoin does not convert Join with always true/false RexNode
> -------------------------------------------------------------
>
> Key: CALCITE-4907
> URL: https://issues.apache.org/jira/browse/CALCITE-4907
> Project: Calcite
> Issue Type: Bug
> Components: jdbc-adapter
> Affects Versions: 1.28.0
> Reporter: Francesco Gini
> Assignee: Francesco Gini
> Priority: Major
>
> JdbcJoin does not handle cases where the condtion is a RexNode that it is
> always true or false. However, SqlImplementor is coded to handle those
> conditions (see SqlImplementor.convertConditionToSqlNode).
> Specifically a cross join is internally represented as a LogicalJoin with
> condition true which is not pushed down into the db.
