Rick Hillegas commented on DERBY-3886:
--------------------------------------
Hi Dag,
I think this is a good use of vtis. SYSCS_DIAG sounds like a good home for your
vti. Your vti seems to be compatible with the charter of that schema as
described in the Reference Guide: "Derby provides a set of system table
expressions which you can use to obtain diagnostic information about the state
of the database and about the database sessions."
> SQL roles: show enabled roles
> -----------------------------

> Key: DERBY-3886
> URL: https://issues.apache.org/jira/browse/DERBY-3886
> Project: Derby
> Issue Type: Improvement
> Components: SQL, Tools
> Reporter: Dag H. Wanvik
> Attachments: enabled-roles.diff, enabled-roles.stat
>
>
> Rick suggested it would be nice to have something to allow inspection of
> enabled roles, cf the
> ENABLED_ROLES view of the information schema, SQL 2003, vol 11, section 5.29.
> I enclose patch suggestion for doing this via a new VTI table and syntactic
> sugar in ij:
> SYSCS_DIAG.ENABLED_ROLES and and ij command "show enabled_roles".
> Not for commit at this point, we may want to handle to general question of
> information schemata
> in another way. What say thee?
