One of the big complaints in SQL Server development has been error handling. SQL Server 2005, however, substantially enhances its capabilies in this area and Leo Peysakhovich brings some code that provides a template for adding error handling to your application.
One advantage of CLR assemblies is the ability to consume web services from within the database. This wouldn’t be easy with T-SQL, and would also require a lot of work in an unmanaged extended stored procedure. With .NET, it’s almost as simple as accessing a local DLL. There are just a couple of extra command-line utilities we need to run to be able to access web services from within a SQL assembly:
SQL Server 2000 has a rock solid backup scheme , but do you really need to run full backups every day? What if you could decide on the fly if it was more efficient for a full or a differential backup? Darwin Hatheway brings us the basis for a scheme that can predict the size of a differential backup by examining how much of the database has changed.
Server 2005 now supports a more programmable error trapping convention in T-SQL code. This error handling is known as the TRY/CATCH block. The TRY/CATCH block allows T-SQL to handling errors like other programming languages, such as Microsoft Visual C# and C++. In addition to the TRY/CATCH block, Microsoft has expanded the set of available system functions in SQL Server 2005 for returning error codes and messages when an error occurs in your T-SQL code. This article will explore the new TRY/CATCH block and explain the new system functions for returning error codes and messages.
Data cleansing is something that constantly occurs in all RDBMSes, not just SQL Server. However it's easier on some platforms than others. New Author Sureshkumar Ramakrishnan has written a script that shows how you can easily remove duplicate rows in SQL Server. Read about his technique and see if it might come in handy in your environment..
Rules play a central role in a wide variety of applications. In addition to the declarative specification of business rules, the simple rule engine design described in this article can be used to implement state machines, predicate dispatchers, or any other rule-based system.
Do you have a need to generate bar codes for an application? Check out this new product, reviewed by Dinesh Asanka, that uses Reporting Services to help you easily print bar codes.
In the past, it was common for an employer to work with their employees and pay to keep their skills current. While this still happens, in this age of high employee (and employer) turnover, many companies are more circumspect about how much they will spend to keep their employees keep up-to-date. At the end of the day, it is your responsibility to make sure this happens and there are many good reasons why you should strive to do so and many ways in which you can do it.
When a new version is released or when existing software is upgraded there is always a learning curve and getting used to new ways of doing things. This article demonstrates how to use SQL Server 2005's catalog views in comparison with using system tables in SQL Server 2000.
SQL Server has a great alerting mechanism for letting DBAs know when some event has occurred, but adding this notification to clients is a little more difficult. New author Stas Vasiljev brings us an extended stored procedure that has has used to allow clients to receive a broadcast when data has changed on a server.
