Each RWDBOSql object corresponds to an Oracle OCI OCIStmt structure. An OCIStmt structure is created and associated with an RWDBOSql object only when the execute() method is invoked on the RWDBOSql object. The OCIStmt structure remains associated until the RWDBOSql object goes out of scope, or an execute() is invoked on the object using a different connection. Invoking execute() on the same connection reuses the same OCIStmt structure.
