Abstract
Performance of database systems may be improved by reducing the processing performed with each database query. For example, when a database query, such as a SQL statement, is executed with a first set of values, the query may be stored as a prepared statement and parsed and optimized as a section. When a similar database query is executed with a new set of values the section may be re-executed with the new set of values without re-parsing or re-optimizing the prepared statement. A similar database query may continue to be executed with new sets of values until the section is invalid because of an alteration to the table definitions of the database schema.
