  • System and method for automatically generating database queries
    Patent number: 8019750
    Abstract: A method of tuning a database query includes selecting a database query, parsing the selected database query to determine relationships between portions of the selected database query, selecting an optimization mode from a plurality of available optimization modes, tuning the selected database query by modifying, at least one portion of the selected database query based on the determined relationships and the selected optimization mode and displaying the modified database query.
    Type: Grant

  • Method and apparatus for viewing the effect of changes to an index for a database table on an optimization plan for a database query
    Patent number: 6898588
    Abstract: A method and apparatus for viewing the effect of changes to an index for a database table on an optimization plan for a database query, such as an SQL statement. A virtual table is created which mimics the structure of an original table on the database. The virtual table is created by copying the original table, excluding any data in the original table. Any existing original indexes associated with original table are copied to define a virtual index associated with the virtual table. References in the query to the original table are replaced with references to the virtual table. The database management system then determines a new optimization plan for the query.
