Abstract
There is provided a method and apparatus for optimizing a database query. Embodiments expand the scope of query optimization to two or more query optimizers. Therefore, a larger class of plan trees can be explored, and a more optimal (for example faster) physical plan may be chosen for execution. The query will continue to be executed by the 'original', “home” or “first” query execution engine, and therefore, a translation or conversion mechanism is be put into place that is able to convert the chosen physical plan into a format that is acceptable to the original optimizer.
