Passed 70-461 Exam : Querying Microsoft SQL Server 2012
Yesterday (Nov 15th 2012) I went through this exam and passed it. From long back I was looking an opportunity to give at least a single SQL Server Certification Exam to check my worth.
Just a week back I scheduled a slot for this Exam (for yesterday). I was looking for some reading material for the same but I couldn’t get any. Though there is a book from Microsoft Press i.e. “Training Kit (Exam 70-461): Querying Microsoft SQL Server 2012“, but it was not available at my nearest.
As I maintain this blog on SQL Server and also evangelize on SQL Server 2012 latest features from long back, so I thought to give it a try and wow I went thru in a single shot!!!
