If you set the Compaiblity Level to 80 for a database in SQL Server 2005, what do you miss out on?

The engine interprets SQL code as if it were SQL 2000 code, so you can't run any 2005 functions. As far as performance improvements in how the tables, indexes, backups, etc. work, those perform at 2005 levels.

It just changes the way the query processor interprets and allows SQL code.

Another thing you will notice is that you cannot run Standard Reports from Management Studio on a level 8.0 database.

one of the interesting things about 90 is that it can treat bit fields as true, false, or NULL (rather than just true or false)
