bindExpression
ValueNode bindExpression(FromList fromList, SubqueryList subqueryList, java.util.List<AggregateNode> aggregates) throws StandardException
ValueNode override.- Overrides:
bindExpression
in classWindowFunctionNode
- Parameters:
fromList
- The FROM list for the query this expression is in, for binding columns.subqueryList
- The subquery list being built as we find SubqueryNodesaggregates
- The aggregate list being built as we find AggregateNodes- Returns:
- The new top of the expression tree.
- Throws:
StandardException
- Thrown on error- See Also:
ValueNode.bindExpression(org.apache.derby.impl.sql.compile.FromList, org.apache.derby.impl.sql.compile.SubqueryList, java.util.List<org.apache.derby.impl.sql.compile.AggregateNode>)
-
printSubNodes
public void printSubNodes(int depth)
QueryTreeNode override. Prints the sub-nodes of this object.- Overrides:
printSubNodes
in classWindowFunctionNode
- Parameters:
depth
- The depth of this node in the tree- See Also:
QueryTreeNode.printSubNodes(int)
