Abstract
A method, system and article of manufacture for query processing and, more particularly, for managing execution of a query against data in a database. One embodiment comprises receiving a query having (i) at least one result field configured to return data from at least one data record included with the database, and (ii) a query condition comprising a field and a query object associated with the field by an operator configured to select values for the field from the query object. The method further comprises determining whether the query object is configured to provide one or more valid values for the field. If the query object is not configured to provide one or more valid values for the field, the query object is transformed into a transformed query object that is configured to provide one or more valid values for the field. Then, the query is executed against the database.
