public class SqlCollectionTableOperator
extends SqlFunctionalOperator

SqlCollectionTableOperator is the "table function derived table" operator. It converts a table-valued function into a relation, e.g. "SELECT * FROM TABLE(ramp(5))".

This operator has function syntax (with one argument), whereas SqlStdOperatorTable.explicitTableOperator is a prefix operator.
