If it doesn't work, how does it fail?

I would write a script that drops and creates all the objects you need
for your setup so that you only need to call it using INPUT from ISQL to
have everything created. You could then call that on your real database,
taking care, of course, not to delete real data. :-)

Things to consider:

* SET AUTODDL and COMMIT
* dependencies and correct sequence of DROP/CREATE
* SHOW GRANT output
