Hi There.  
Does anybody know of a resource explaining how to write a rails  
adapter for a custom (say, a funky flavour of SQL, or even non-SQL)  
database?

Thanks  
Kretch

Read the code of the existing adapters, or any specific one that comes  
close to what you’re trying to do. If you want to write your own adapter  
that’s at least as deep as you’ll have to dive into the code that’s  
already there.
