Examples of JoinNode

com.facebook.presto.sql.planner.plan.JoinNode
com.foundationdb.sql.optimizer.plan.JoinNode
A join between two tables / subjoins.
org.apache.derby.impl.sql.compile.JoinNode
A JoinNode represents a join result set for either of the basic DML operations: SELECT and INSERT. For INSERT - SELECT, any of the fields in a JoinNode can be used (the JoinNode represents the (join) SELECT statement in the INSERT - SELECT). For INSERT, the resultColumns in the selectList will contain the names of the columns being inserted into or updated. @author Jeff Lichtman

A two-input Rete-OO join node . @see org.drools.reteoo.TupleSource @see org.drools.reteoo.TupleSink @author bob mcwhirter
org.openbp.core.model.item.process.JoinNode
A join node is the equivalent of an 'if' statement in a programming language. Depending on the evaluation of its expression Value, forwards control to the 'Yes' or 'No' socket. @author Heiko Erhardt

org.voltdb.planner.parseinfo.JoinNode
JoinNode class captures the hierarchical data model of a given SQl join. Each node in the tree can be either a leaf representing a joined table (m_table != null) or a node representing the actual join (m_leftNode!=0 and m_rightNode!=0) filter expressions

        // Check the network formation, to ensure the RiaNode is shared.
