Abstract

See full text

Methods, systems and apparatus for implementing behavior of a user defined type (UDT) in a database by providing a data table with multiple rows and generating a UDT table having only a single row. An instance of a UDT is created and stored in the single row of the UDT table. A query having a Cartesian product is implemented to join the UDT table and data table for invoking behavior of the UDT and generating a resultant data table without increasing cardinality thereof. The single instance of the UDT may be shared amongst several users of the database as a result of all required persisted objects of the UDT residing within only a single row of the UDT table.
