Francesco Gini updated CALCITE-4907:

Description: JDBC adapter (in JdbcJoinRule) cannot push down join ON TRUE 
(cartesian product) or ON FALSE. This results in implementing the join in 
memory via _EnumerableNestedLoopJoin_ which is a less efficient implementation. 
 (was: Cross joins (LogicalJoin with condition {_}true{_}) are not pushed down 
in the database when using the JdbcAdapter. This results in implementing the 
join in memory via _EnumerableNestedLoopJoin_ which is a less efficient 
implementation.

 

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).)
