In processing a query, a database server parses a string describing a query into a query representation. The query string is parsed again to generate a replica of the query representation. Various transformations can be applied to the replica in order to reduce the amount of processing for the query. In addition, transformations are applied to the query string before parsing again to produce a transformed query representation. A transformed query representation is selected for processing a query according to an estimated cost of using the query representation.
