Posted Sep 24, 2015 by Pragmatic Works

Kathy Vick and Rowland Gosling are Pragmatic Works' resident experts on disaster recovery. Through their vast experience, they've noticed many common mistakes that DBAs are making and they're sharing their insight to prevent your recovery from being a disaster of its own:

Not just any testing, but real tests that help you truly verify the state of your code, applications and data. I like Test Driven Development, but really any approach that focuses on automated, repeatable tests that verify meaningful functionality I find hugely beneficial. And almost no one I’ve ever talked to about this topic has disagreed with me. (There was that one guy, but he was a FoxPro developer, so...) But there’s often a point where the conversation goes sideways. Usually, it starts something like this:

Posted Sep 01, 2015 by Ginger Grant

There may be a time when you will need to create a table containing a series of dates. Perhaps you want a date table for a data warehouse or a data model in Excel’s Power Pivot. There are a number of ways you can create a date table in SQL Server. I will show a method, which we recommend at Pragmatic Works, that uses a Common Table Expression [CTE].
