The XML exist() method is used, often in a WHERE clause, to check the existence of an element within an XML document or fragment. The nodes() method lets you shred an XML instance and return the information as relational data.

Microsoft IT protects against unplanned Transactional Replication outages and issues by using best practices and proactive monitoring. This results in increased stability, simplified management and improved performance of transactional replication environments.
In a previous tip on Monitor Your SQL Server Virtual Log Files with Policy Based Management, we have seen how we can use Policy Based Management to monitor the number of virtual log files (VLFs) in our SQL Server databases. However, even with that most of the solutions I see online involve the creation of temporary tables and/or a combination of using cursors to get the total number of VLFs in a transaction log file.

In this level we will be discussing how to find and update records in your database, and discuss the pitfalls you might run into when using the UPDATE statement.
As the SQL Developer community grows to embrace the benefits of test-driven development for databases, so the importance of learning to do it properly increases. One way of learning effective TDD is by the use of code kata – short practice sessions that encourage test-first development in baby steps. I have a limited number of licences for SQL Test to give away free – just for practicing a bit of TDD and telling me about it.

In this article I will show you a PowerShell script that you can use to find large files on your disks.
