Let us learn in this blog about sys.sql_expression_dependencies.
A very common question which I often receive are:
How do I find all the tables used in a particular stored procedure?
How do I know which stored procedures are using a particular table?
As you know I have been writing on Columnstore Index for quite a while. Recently my friend Vinod Kumar wrote about SQL Server 2012: ColumnStore Characteristics. A fantastic read on the subject if you have yet not caught up on that subject. After the blog post I called him and asked what should I write next on this subject. He suggested that I should write on DMV script which I have prepared related to Columnstore when I was writing our SQL Server Questions and Answers book. When we were writing this book SQL Server 2012 CTP versions were available. I had written few scripts related to SQL Server columnstore Index. I like Vinod’s idea and I decided to write about DMV, which we did not cover in the book as SQL Server 2012 was not released yet. We did not want to talk about the product which was not yet released.
I recently received email from one of my very close friend from California. His question was very interesting. He wanted to know how many virtual processors are there available for SQL Server. He already had script for SQL Server 2008 but was mainly looking for SQL Server 2000. He made me go to my past. I found following script from my old emails (I have no reference listed along with it, so not sure the original source).
SQL SERVER – DVM sys.dm_os_sys_info Column Name Changed in SQL Server. Let us learn about it in today’s blog post.
In this blog post we will see three new DMVs which are introduced in Denali. The DMVs are very simple and there is not much to describe them. So here is the simple game. I will be asking a question back to you after seeing the result of the each of the DMV and you help me to complete this blog post.
