The great debate over NULLs will probably never end. Should we use them in our databases? What meaning do they have? These are all
valid questions. In this article SQL Server expert Michael Coles takes a look at the problems that are inherent in eliminating NULLs completely from
a database.
The NEWSEQUENTIALID system function is an addition to SQL Server 2005. It seeks to bring together, what used to be, conflicting requirements in SQL Server 2000; namely identity-level insert performance and globally unique values.
If you are thinking of taking a SQL Server 2005 MCP exam, now is the time to do it. And with exam insurance, you can get two chances to pass and a free year of Technet!
SQL Server 2005 has so many new features that in my opinion if you read only BOL for a year you'd find something new every day. One of those is Multiple Active Result Sets or MARS. Multiple Active Result Sets is a new SQL Server 2005 feature that, putting it simply, allows the user to run more than one SQL batch on an open connection at the same time.
What's the best way to change the default backup directory for a server, using SSMS or Enterprise Manager, without changing all the default directories at the same time? What is the TSQL to do it? A prize for the best correct solution.
In the fourth installment of this series, Jacob Sebastian moves on to SQL Server 2005 and the new XML capabilities that make
working with XML data easier than ever.
Having been at the sharp end of many successful SQL Server solutions, I believe there are some fundamental principles that all successful SQL Server installations have in common. Whilst the challenges in delivering an enterprise-scale database-intensive application can be wide and varied, there are a few basic practises that will give you the best possible chance of success.
his white paper covers some of the operational and administrative tasks associated with SQL Server 2005 security and enumerates best practices and operational and administrative tasks that will result in a more secure SQL Server system.
In the previous articles, Jacob Sebastian looked at using XML to save a sales order with variable numbers of line items to a SQL Server
2000 database. In this part, he expands upon the processing to access that data from multiple nodes.
This article introduces some techniques that will allow you to pinpoint exactly where the performance issues are in your system, so you'll know exactly where to spend your time (and money) in solving them.
