摘要
A method, computer program product, and system are provided for accelerating a query in a database system. For example, an embodiment of the method may include generating a data structure identifying a set of rows that satisfy conditions local to a table prior to an evaluation of a query and modifying the query based on the data structure. In addition, the method may include repeating the steps with respect to generating the data structure and modifying the query, if one or more additional local conditions are inferred from modifying the query based on the data structure.
