Structured exception handling was introduced in SQL Server 2005 and provides a strong alternative to using @@ERROR. It will be discussed in the next lesson. A large amount of existing SQL Server error handling code is based on @@ERROR, so it is important to understand how to work...
Error handling in SQL Server 2008 needs careful implementation. The Microsoft “Oslo” Repository’s API has the further problem that we cannot mandate the error handling logic in our callers. Thus a stored procedure call could be in a transaction or not and in a try-catch block or n...

The simplest kind of error handling is to know whether a method succeeded in its operation or not. This level of error handling is accomplished by looking at the return value of the method. Most methods in the library return a result of typeoresult. Anoresultwill either have the value OSU...
