ABSTRACT:
An automated method is provided for optimizing a query for retrieving data from a relational database in a computer relational database management system. The method uses rules for identifying queries for which duplicates are a factor in retrieving the proper data from the database. The method then merges queries with table expressions, views and subqueries when possible without causing duplicates to be unnecessarily retrieved.
