Microsoft introduces new operators PIVOT and UNPIVOT in SQL Server 2005. Traditionally we create queries using the CASE statement and aggregate function in order to produce cross-tab reports. This article illustrates the usage of the new operators, PIVOT and UNPIVOT.

We will continue our review of Foreach enumerators starting with Foreach ADO, since this one probably qualifies as the most popular choice in its category. This is due to the fact that ADO recordsets offer a convenient way of dealing with data sources, regardless of their type (for example, within SSIS, you can easily populate a recordset by executing a SQL query or by reading the content of a flat file)
Most skilled professionals—be they butchers, bakers or software makers—take pride in selecting their own tools of the trade. Why is it then that developers and DBAs in large corporations often are not afforded the same professional courtesy or opportunity? The tools they use are just as vital to their livelihood, yet when it comes to high-cost software, developers and DBAs often have no input into what is purchased for their use.
Who builds SQL Server? It's an interesting collection of individuals and we're looking to bring you some profiles of them all. In the first installment of this series Steve Jones interviews Euan Garden, longtime member of the team.
This article discusses three common problems DBAs are likely to encounter when columns have the identity property, which is defined as an attribute of int, smallint, bigint, decimal, numeric or tinyint columns that will auto-increment their value when data is inserted. These problems are humorously referred to as the identity crisis.

A SQL Server DBA seems to be a stable job and many of us stick with the same job for an above average length of time. However employee retention in general is important to a strong and healthy company. Steve Jones starts a new series looking at this topic and why an employer might want to worry about retention.
Programmers, webmasters, Web services developers and database administrators (DBAs) are not strangers to the "Can we have it tomorrow?" request. That's why software and web developers have embraced a continuous stream of silver bullet technologies that promised to accelerate development. The developer community has experienced "web time", object-oriented programming (OOP), rapid application development (RAD), "extreme programming" and "agile development". Accelerated development schedules put a premium on understanding architecture and knowing how to match the tools to the job. That means understanding today's model of applications as services and what role a database can play. If you understand SQL technology, for example, you can adapt databases to application and service requirements by embedding logic in a database.
How many times have you wished you could throttle the CPU use of SQL Server? Or for a database? Prevent your developers from using too many resources while sharing the server with production or QA. ArmTech for Windows can do this and Dinsesh Asanka brings us a review of how this product worked in his environment.
