For some time, Microsoft had a few window functions, but not the full set specified in the SQL 2003 standard. Now, in SQL Server 2012 we have the whole range, and extremely useful they are too. There's no longer an excuse to avoid them, particularly now you have Rob Sheldon's gentle introduction.

Normally, the query Optimiser won't consider 'bushy' plans, where both operands to a join operator could be intermediate results from other joins. This means that it won't produce good query plans for some types of query. Hints, by themselves won't do it. More powerful magic is required.

n a database I currently support, the application makes use of db_datareader and db_datawriter to give permissions to the tables. In a different database, it's even worse as the application uses db_owner. We're adding new tables to both databases and we don't want the application to have access to these tables.

If you’re involved in the database world it’s hard to have missed the rise of the “no-sql” database products, designed to – depending on your view or the product I suppose – make databases simpler, break out of the transaction database paradigm, scale out across hundreds of machines, make it easy to change the db design (or not require one). I think some of the problems no-sql tries to solve are real, others reflect a lack of awareness/training/tools on how and why relational databases could not just solve the problem, but solve it better.
