Hello,

Up to now I developed some small basic Rails applications. I've always 
started with a DB model and the rails mapping worked as expected.

Now I'm confronted with the situation, that the DB model is already done,
and I cannot change it. Of course there is no rails naming convention,
So I need to programm the SQL statements. 

What is the best way to do it? Where should I place the SQL code (model,
helper, controller?). How can I create a pagination table? How can I
sort the table?

Some working example code (not only snippets) would be very helpful.

Thanks.
Matthias
