1. A system, comprising: a creation time logic, stored on a computer-readable medium to create an association between one or more created materialized views and one or more containment expressions having respective sets of values for a bind variable prior to execution time and to store the association for processing of future queries, where an association indicates that a materialized view contains data useful in determining results for a query when the bind variable has a value in the associated set of values; an execution time logic, stored on a computer-readable medium, to receive the query having a bind variable, and to receive a value for the bind variable when the bind variable is resolved, and use the association to determine whether to access the materialized view in the execution plan for the query.
