in ij

-------------------------------
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.
