SqlValidator	Validates the parse tree of a SQL statement, and provides semantic information about the parse tree.
SqlValidatorCatalogReader	Supplies catalog information for SqlValidator.
SqlValidatorNamespace	A namespace describes the relation returned by a section of a SQL query.
SqlValidatorScope	Name-resolution scope.
SqlValidatorTable	Supplies a SqlValidator with the metadata for a table.
SqlValidatorWithHints	Extends SqlValidator to allow discovery of useful data such as fully qualified names of sql objects, alternative valid sql objects that can be used in the SQL statement (dubbed as hints)
