copy
public JdbcRules.JdbcJoin copy(RelTraitSet traitSet, RexNode condition, RelNode left, RelNode right, JoinRelType joinType, boolean semiJoinDone)
Description copied from class:Join
Creates a copy of this join, overriding condition, system fields and inputs.General contract as
RelNode.copy(org.apache.calcite.plan.RelTraitSet, java.util.List<org.apache.calcite.rel.RelNode>)
.
-
computeSelfCost
public RelOptCost computeSelfCost(RelOptPlanner planner, RelMetadataQuery mq)
Description copied from interface:RelNode
Returns the cost of this plan (not including children). The base implementation throws an error; derived classes should override.NOTE jvs 29-Mar-2006: Don't call this method directly. Instead, use
RelMetadataQuery.getNonCumulativeCost(org.apache.calcite.rel.RelNode)
, which gives plugins a chance to override the rel's default ideas about cost.- Specified by:
computeSelfCost
in interfaceRelNode
- Overrides:
computeSelfCost
in classJoin
- Parameters:
planner
- Planner for cost calculationmq
- Metadata query- Returns:
- Cost of this plan (not including children)
-
estimateRowCount
public double estimateRowCount(RelMetadataQuery mq)
Description copied from interface:RelNode
Returns an estimate of the number of rows this relational expression will return.NOTE jvs 29-Mar-2006: Don't call this method directly. Instead, use
RelMetadataQuery.getRowCount(org.apache.calcite.rel.RelNode)
, which gives plugins a chance to override the rel's default ideas about row count.- Specified by:
estimateRowCount
in interfaceRelNode
- Overrides:
estimateRowCount
in classJoin
- Parameters:
mq
- Metadata query- Returns:
- Estimate of the number of rows this relational expression will return
