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

Håvard Mork updated DERBY-1164:

    Attachment: 1164_2.diff

Thank you for all your feedback. I've thought more about this, but I've been unable to find
a good way to using the returned resultsets from DatabaseMetaData directly, while still getting
a nice layout.

In the attached patch, I have made local versions of the DatabaseMetaData query strings. Where
possible, I've tried to cast data types so rows will fit on 80-char display widths. As for
the querying parts, I'm unsure wether this is the best approach.

> 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.
