We are running SQL Server in 6.5 compatability mode. We have some queries
that are supported in 2000, that is the reason for the 6.5 version. What,
if any, would be gained in performance by switching to 2000.
As far as I'm aware, the compatibility level affects functionality, not
performance as such, although since I haven't used it much myself, I'm not
100% sure about that.
In any event, MS recommends using a compatibility level only as a temporary
step during an upgrade, and moving to 2000 level would give you extra
functionality (eg. functions, indexed views) which isn't available in 6.5
mode. So it would probably be a good idea to review and update your code
anyway.
If you're having difficulties doing that, then you can post an example of
the problem code (including DDL and sample data, if appropriate), and the
errors you get in 2000 mode, and someone may be able to suggest an
alternative way to write the queries.
