Abstract
A database query is received including a logical table identifier at a distributed database node within a distributed network of databases. The logical table identifier includes a dynamically-updatable constant column identifier. Local logical table definitions are filtered based upon the logical table identifier and the dynamically-updatable constant column identifier to identify a local logical table associated with the logical table identifier and the dynamically-updatable constant column identifier. A local query response is formed including data retrieved from a local physical database table mapped by the local logical table in response to identifying the local logical table associated with the logical table identifier and the dynamically-updatable constant column identifier. The database query is responded to, in response to forming the local query response, with at least the local query response. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
