This could be also a good solution, but unfortunately it gives so many 
errors that it would be more simple to update the DBIC classes manually.
I've just tried create_ddl_dir again to see if it works better now, but I 
needed to make more tens of corrections for a database with only 10 simple 

The main problem is that the DBIC class files as they are now, are harder to 
update automaticly. It would be nice if the information about tables and 
their columns would be kept in separate files than the rest of the code. In 
that way, the code could get the information about tables from those 
separate files (when using create=static) or even from the database when 
using create=dynamic.

Such an interface would be much flexible, but I don't even know if it is 
possible to do it...
