Oracle Applications Testing Suite OATS

I got a chance to download and try a new product called Oracle Applications Testing Suite. It allows a script to be recorded and played back to test functionality. I then was able to load the test script into Oracle Load Testing web and test Concurrent Users thresholds. Its easy to use and gets my vote for stress/load testing applications. I'm sure there are tons of features I haven't seen yet, but its a powerful tool from my initial testing.

Common Table Expression (CTE)

Introduced in SQL Server 2005, the common table expression (CTE) is a temporary named result set that you can reference within a SELECT, INSERT, UPDATE, or DELETE statement. You can also use a CTE in a CREATE VIEW statement, as part of the view’s SELECT query. In addition, as of SQL Server 2008, you can add a CTE to the new MERGE statement.

SQL Server supports two types of CTEs—recursive and nonrecursive. In this article, it explains how to create both types. The examples provided are based on a local instance of SQL Server 2008 and retrieve data from the AdventureWorks2008 sample database.
