--------------------------------------

Hi Kevin,

Thanks for your interest in this issue. A good place to start would be to look at the enabled-roles-3.diff patch which Dag attached to DERBY-3886. In that patch, Dag added 2 new ij SHOW commands for displaying information about ROLES. The patch steps you through all of the work which you need to do to add a new ij command, from adding your new command to the ij grammar in ij.jj all the way through to writing a regression test to verify that your command works. I would recommend starting in the ij.jj grammar and follow what Dag did for SHOW SETTABLE ROLES.

> Currently, the ij SHOW command can give you information on a number of schema objects, including procedures. It should be fairly easy to add SHOW FUNCTIONS as well. This request surfaced on the user list: http://www.nabble.com/How-can-i-see-my-self-defined-functions--td18773980.html#a18773980
