I read this awesome post by Joe Sack, titled “Detecting Cardinality Estimate Issues with sys.dm_exec_query_stats”.
I was amazed by the beauty of his detection query, ran it on my environment, and discovered some interesting things.

I’m going to Nottingham, England, fabled home of Robin Hood, where I’m going to eat fish and chips and talk about SSIS. How’s that for tying seemingly unrelated topics together?
We got a call last week about an application that was running slowly. The server was showing about 80% CPU utilization consistently, IO was through the roof etc. It was taking something like 15-20 seconds to log in (doesn’t seem like much unless you are used to 4 or 5).… Read more
This weekend of SQL Saturday #183 in Albuquerque, NM. It’s the first SQL Saturday in that state, and it’s a relatively short drive from Colorado. Six hours from my house, S of Denver, and a nice city. My brother used to live there, and I made a few trips to… Read more
Recently I was brought in to help troubleshoot performance issues on a database server. Going through my typical check list I noticed memory pressure on the box and made the recommendationof more memory which was simple to fix. What caught my attention though was that blocking was occurring on a… Read more
I’ve been exploring execution plans in Azure SQL Databases a lot lately. I’m getting a presentation together for some upcoming SQL Saturday events (first one is SQL Saturday #177, Silicon Valley).

Recently I posted SSIS 6 million rows in 60 seconds using standard laptop. Today I'm still using laptop and one physical disk…
Earlier on my blog I posted about how you can attach a database using T-SQL when no log file is available. You can catch that here. In this post we will see how it can be attached using GUI.

Anyone who has been following this series of self-tutorials has probably grown accustomed to me adding some kind of disclaimer about my shortcomings as a data miner. These blog posts are designed to simultaneously give the most under-utilized part of SQL Server some badly needed free press,… Read more

During the last few years I've worked extensively with transactional replication and have written a handful of scripts that have found a permanent home in my "useful scripts" toolbox. I've provided these scripts as downloads whenever I've presented about replication...but not everyone who has worked with replication has been to… Read more
Have you ever needed to figure out which filegroup your tables are located within? If you had to do this, you might think it’s as easy joining sys.tables to sys.filegroups. But its a little more complicated than that because tables aren’t stored in filegroups.
It’s The Indexes
It’s the… Read more
A tribute is an expression of gratitude or praise. Last year I started a series about individuals who have impacted my career. I do this as a tribute to my father-in-law, Ed Jankowski who passed away a few years ago. Check out my original post about him and his impact… Read more
This is an annoying problem I have had a few times: I open a SQL Server Integration Services (SSIS) project in SSDT, and see that the Toolbox pane is empty, displaying a “There are no usable controls in this group. Drag an item onto this text to add it to… Read more

SQL Server clusters are widely used, and widely misunderstood, which makes people like our good friend (and clustering MVP) Allan Hirt cry bitter tears. So here are a few notes for you and yours.
Cluster IS NOT Disaster Recovery
A cluster does not protect against disaster. Unless it’s a very,… Read more
