This brings up an interesting idea. What if it were possible to set
some kind of rules on DDL at database creation time? For example, I'd
like to be able to throw an error if somebody tries to name an object
any of the SQL keywords.
Other possible rules:
* Every table must have a comment
* noCamelCaps
* downcase all entities
* underbar_separators_required
* abbrev_w_beg, nt_by_rmvng_vwls
* Your favorite algorithmic coding standard here
What do y'all think?
Cheers,
D
