Re: custom metadata Patrick Meyer Tue Aug 02 09:01:17 2011

The COMMENT ON feature is exactly what I need. I just added my vote in favor of it.

In the meantime, I'll use Raymond's recommendation to check the column names for my "type" of table.

Thanks everyone for your recommendations.

I have an application that creates tables in a derby database. Some of the tables contain specific variables (i.e. predetermined column names) and, therefore, are of a certain "type". Some functions in the application only work with some "types" of tables. Is there a way to use metadata to identify which "type" of table a user has selected?


Hi Patrick,

Derby doesn't provide a mechanism to tag a table with extra metadata. Some databases allow you to tag schema objects with comments. See https://issues.apache.org/jira/browse/DERBY-4379. If that would solve your problem, you may want to add a comment to that issue. You may also want to vote for DERBY-4379 in order to boost its chances of being addressed.

Hope this helps,
