DESCRIPTION

In DBIO, query results normally arrive as instances of a specific Result Class determined by the main query source. A result class is both the runtime API for rows and the place where DBIO learns the schema metadata for a table or view.

Because a result class plays both roles, its available methods come from several cooperating modules. This document serves as a high-level map for declaring result classes and for finding the deeper API documentation.
