In previous versions of SQL Server, working with large value data types required special handling. Large value data types are those that exceed the maximum row size of 8 KB. SQL Server 2005 introduces a max specifier for varchar , nvarchar and varbinary data types to allow storage of values as large as 2^31 -1 bytes. Table columns and Transact-SQL variables may specify varchar(max) , nvarchar(max) or varbinary(max) data types. Previously, only SQL Server data types such as text , ntext and image could attain such lengths.
I’ve been asked this question a few times when looking into performance problems on a website, and the short answer is, it’s not. SQL Server is a very efficient database. It’s important to remember that a database is just a runtime for your SQL code. It’s just doing what you ask it to do, nothing more, nothing less.

NEW!!! Subscribe to my newsletter: How to identify SQL Server performance issues, by analyzing Profiler output? (See also: Automating server side tracing in SQL Server ) It is always better to be proactive than reactive, when it comes to identifying and eliminating SQL Server performance issues. In this article, I am going to explain the method I follow, to identify performance issues in my database applications, before those applications go into production environment. Once the application is completely built and tested, I will conduct something called a "Load test" or "Stress test".

(Anton Klimov, a developer on the SQL Server Native Client team, wrote the following article.) Connection strings for an OLE DB provider is a concept that causes a lot of confusion. One problem is that OLE DB itself does not define connection string as a provider concept. The documentation at Connection String Syntax ( http://msdn.microsoft.com/en-us/library/ms722656(VS.85).aspx ) says: "A connection string is a string version of the initialization properties needed to connect to a data store and enables you to easily store connection information within your application or to pass it between applications.

Denny Cherry, Contributor As with other applications, SQL Server applications need memory to run. However, unlike most applications, SQL Server allows you to decide just how much memory it can use. That's good because SQL Server likes lots of memory. Server memory options are set either within the GUI or with the sp_configure procedure by adjusting the "max server memory (MB)" setting. Setting server memory properties.
