Pros and Cons of Switching to Database Managed Services

The term is widely used and covers so many things simultaneously, so it is hard to figure out what it means exactly. Do managed services include database administration only or do they also cover installation, upgrades and migration to other servers? Are database managed services always 24/7 or are there any other options? Do DBMS involve routine maintenance procedures or can they also handle critical issues? There are literally dozens of questions! Reporting? Custom service? Performance tuning and bottle-neck analysis? Too bad, each database managed service provider answers these questions differently, in its own way.

Database consultancy: CROSS APPLY

This article is dedicated to the operator APPLY, and more specifically its type CROSS APPLY. This statement was first introduced in SQL Server 2005, but unfortunately many have not learned how to use it, maybe it's because of the fact that the BOL (SQL ServerBooksOnline) this operator is not well and has a very "dry" examples of its use. In this article, I'll show some interesting demonstrations, where the operator can come in handy.
