Abstract
A query syntax analysis and postprocessing system and method receives a query request specifying values of a data type directed to a database without native support for the queried data type. A query engine or process for receiving a query request defined by a query syntax traverses the query request for a specification of an unsupported value or expression. In a large, distributed database environment, the query request may implicate multiple physical data stores, each having specific formats and recognized syntax. Values of unsupported or non-native types, or expressions that evaluate to an unsupported or non-native type, are identified and replaced with an expression that is recognized by the legacy database.
