摘要
A method and apparatus for densification of data is provided. A method and apparatus for including a construct for partitioning data within a DML statement is provided. The construct for partitioning data may not necessarily perform a densification of data, and the densification of data may not necessarily include a construct for partitioning data. In an embodiment, the syntax of an OUTER JOIN is extended to include a PARTITION BY construct that may be used for data densification.
