What is the best approach for updating the schema and the database
when one of us makes an update to the db structure?
currently, we have to blow out the tables and recreate them manually
to reflect the new updates.
I'm probably being naive, but don't you have an ALTER TABLE sql
statement available to you?
Also, for what it's worth, I don't build tables manually (at the command
line or whatever). I always create a script which will build the tables
I need. If, for some crazy reason, I do have to restart from scratch,
it's a simple matter to alter that script and re-run it.

Scripting is the way to go for database changes: every time I have to make a
schema change I write an SQL script to do the job, including any manipulation of
data required. Then I make a copy of the real data and test the hell out of the
change script before going live with it.
You can commit the database script to your source control at the time you commit
the code changes, and then when you update the live system you run any new
scripts at the same time.
