One thing that comes to mind is that you have to quote table and column names that don't follow the identifier pattern [like so] instead of "like so". Though I haven't kept up to date on this, maybe it can now also support SQL standard compliant table/column name quoting. Even MySQL can now do that (with a config option, at least). That's only a tiny thing, though. I'm sure there is more. I don't use Microsoft SQL Server. Quite happy with PostgreSQL (and SQLite for tiny in file things).
