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.

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.

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.

AMO lets developers put their own programs into action. It facilitates client-side custom programming as Decision Support Objects (DSO), the object model in SQL Server 2000 Analysis Services. With AMO, a whole range of data mining questions can be answered at the operational level. This means that sales and marketing departments get answers more quickly and thus can make informed decisions. Specialized resources, like the IT team and analysts, can be brought in when they're needed most.
