摘要:
A distributed query system includes a distributed collection of dynamically created compiled queries. As each client submits a query, a parameterized query skeleton is identified, which identifies the general form of the query, and the parameters associated with the particular query. If a compiled form of the skeletal query is available within the distributed system, it is executed with the parameters of the current query. If the compiled form of the skeletal query is not available within the distributed system, a compiled form is created, and the location of this compiled skeletal query is stored for subsequent access by this client, or other clients. The executable compiled skeletal queries may be stored at each client system, in a commonly available server storage system, or within one or more database servers. A routing system may be provided to efficiently route parameterized queries to the appropriate location(s) of the compiled skeletal query.
