SQL Server 2000 introduced user-defined functions (UDFs), and they were immediately hailed as a great tool for encapsulating repetitive code, as well as allowing you to perform more complicated processing directly in an SQL expression. On its face, that claim is valid. You can certainly improve readability and maintainability with UDFs. But cleaner code will be cold comfort if your queries bog down and lock up your server.
One of the less exciting, but perhaps very powerful new features in SQL Server 2005, the Service Broker is an asynchronous communications method. MVP Srinivas Sampath brings us the second part of his series looking at what you can accomplish with a practical example.
How much backup data should you keep around and what are the implications? Part 2 of a series looking at backups and their implications.
DTS was one of the most amazing new features of SQL Server 7 and in SQL Server 2005 it has been renamed to Integration Services. This component has some incredible new capabilities, many of which come at a steep learning curve. New author Kristian Wedberg brings us a basic article and some code on how you can SSIS to generate test data.
SQL Server Database administrators often generate SQL Statements and execute the generated SQL statement in order to simplify certain tasks. It has always been a twin operation. This article illustrates how to use un-documented stored procedures to execute the generated SQL Statements directly.
We've had a lot of coverage of dynamic sql (including another great one from Robert Marda later this week) but this one is a little different. Done in a question/answer format, Andy tries to explain to junior developers why dynamic sql is to be avoided, how to do so, what to do when you can't.

Who builds SQL Server? It's an interesting collection of individuals and we're looking to bring you some profiles of the entire team. Brian Weckler, reporting services guru, is the subject of this interview.
We will use SWITCH() to enact conditional formatting in a couple of different ways. First, we will use it to drive formatting of a value to meet requirements that are based upon the magnitude of the value itself. As a part of our practice with SWITCH() to achieve our ends, we will delve into a popular formatting convention for negative (and other "outlier") numbers.
SQL Server 2000 has a great scheduler in SQL Agent, but it isn't integrated with anything else. And with lots of servers, having a centralized environment is essential to keeping yourself from being overworked. Author Sureshkumar Ramakrishnan brings us his technique for running SQL Server jobs from an external scheduler.

I have a database, DNRTest, that has a number of tables and other objects in it. The other day, I was trying to mock up a test and ran this code on the same server:
-- run yesterday CREATE DATABASE DNRTest2 GO USE DNRTest2 GO CREATE TABLE NewTable (id INT) GOToday, I realize that I need a copy of DNRTest for another mockup, and I run this:
-- run today USE Master BACKUP DATABASE DNRTest TO DISK = 'dnrtest.bak' GO RESTORE DATABASE DNRTest2 FROM DISK = 'dnrtest.bak' WITH REPLACEWhat happens? See possible answers
