> Now that vararg routines have been added to Derby (see DERBY-3069), I would
> like to add a new vararg system procedure for registering and unregistering
> optional packages of Derby tools. For starters, these would be tools which
> aren't checked into the Derby codeline but are just attached to various
> JIRAs. These tools are:
> o DBMDWrapper (DERBY-3973 and DERBY-5967) - This tool creates functions and
> table functions for all of the DatabaseMetaData methods so that you can write
> complicated queries which join and filter JDBC metadata.
> o ForeignTableVTI (DERBY-4962) - This tool creates views against foreign
> databases so that you can bulk-import foreign data into Derby without
> indirecting through csv files.
> It also may be possible to use this approach to expose the log and data file
> reading tools attached to DERBY-5195 and DERBY-5201.
> The new system procedure would look like this:
> create procedure syscs_util.syscs_register_tool
> (
> toolName varchar( 32672 ),
> boolean register,
> optionalArgs varchar( 32672 ) ...
> )
> language java parameter style derby modifies sql data
> external name 'willFigureOutWhereToPutThis';
> The arguments would have these meanings:
> o toolName - A name specific to the tool.
> o register - True means "register the tool" and false means "unregister the
> tool".
> o optionalArgs - Each tool could have its own variable set of additional
> configuration parameters.
> By default, only the DBO could run this procedure. The DBO could grant
> execute permission to other users.
> The known tool names and their optional parameters would be documented in the
> Derby Reference Manual in the section on syscs_util.syscs_register_tool.
> I am thinking that we should put the optional tools themselves in
> derbytools.jar. We might want to document all of the optional tools in the
> Tools Guide, although I can see arguments for documenting some tools in the
> Admin Guide.
> I would appreciate other people's thoughts about this proposal.
> Thanks,
> -Rick
