Latest Patents

One of his latest patents is titled "Load Committed Isolation Processing." This innovation defines a database table as a load isolated table (LDI table) that supports a current table version number, multiple row versions, and special load protocols. An isolated loading statement on the LDI table is identified in a Data Manipulation Language (DML), which causes the table to be placed in an isolated loading state associated with an incremented new value of the table's current version number. A designated group of DML operations in one or more sessions are then used to load or modify rows in the table, and affected rows are marked with the uncommitted new version. Read-committed queries supported for LDIs ignore the uncommitted rows during an isolated load, seeing only previously committed versions of the rows. When an end isolated loading on the table is identified, the table's version is updated to the new incremented value, causing the newly loaded or modified rows to be recognized as committed by subsequent read-committed queries.

Another notable patent is "Optimizing the Processing of In-List Rows." This patent optimizes a SQL query that includes an IN-List by utilizing an array insert to insert the IN-List into a spool and piggybacking IN-List rows into a join step. This innovation enhances the efficiency of database queries, making data retrieval faster and more effective.
