another SQL statement is called a subquery.SelectStatement,

Expression. This method can be used to optimize traversing
the children since a new list is not created every time Expression.children() is called.
This does not traverse the Expression sub-hierarchy, use a subclass of
AbstractTraverseChildrenVisitor in order to traverse the entire sub-hierarchy.
