> The client JDBC driver will need to call stored procedures (ref DERBY-2257)
> to operate on LOBs identified by locators. We should create a framework that
> implement the stored procedure calls. This way, the rest of the client code
> can call methods in this framework when needing to call the stored procedures
> without having to prepare SQL statements themselves.
> The framework should make sure that prepared statements are reused within a
> connection. Each procedure call should only be prepared once per connection.
> Since LOBs can not be parameters to stored procedures, the framework should
> make sure that calls involving a byte[] or String that does not fit in a
> VARCHAR (FOR BIT DATA), are split into several calls each operating on a
> fragment of the LOB.
