Subject [jira] Commented: (DERBY-1164) 'show tables' and 'describe' commands in ij

Rick Hillegas commented on DERBY-1164:
--------------------------------------

Hi Håvard,

Thanks for this useful patch. The parser productions look good to me. However, I'm hesitant
about modelling the result as a vector. I think it would be better to return results which
look more like tables rather than coalescing all the information into a single column. I think
you will end up with something more powerful if you write an implementation of ijResult which
wraps a ResultSet. This will let you rapidly display all sorts of DatabaseMetaData calls.

> New users migrating from mysql are familiar with commands 'show tables' and 'describe'
 to respectively display all permanent tables, and show fields in a given table. These are
not standard sql, but I suggest to implement them only in the IJ tool for user-friendliness.
> As suggested in db-dev, using DatabaseMetaData should provide the necessary query strings.
