Forcing Execution Plan

Very rarely there is a need to force an execution plan and even more rarely we should be doing it. But once you decide there is no other way or you need a quick temporary workaround to get production going and gain some buffer time for yourself to do proper… Read more

The need for having both a DW and cubes

I have heard some people say if you have a data warehouse, there is no need for cubes (when I say “cubes” I am referring to tabular and multidimensional OLAP models).  And I have heard others say if you have OLAP cubes, you don’t need a data warehouse.  I strongly… Read more

Selecting a Random Row From a Table

A couple of times recently I’ve seen the question asked, ‘How can I select a single row at random from a table?’.

There are often a few ways of doing this suggested, most seem to rely using CTEs or temp tables.  I thought I’d share, in a quick post a… Read more

Friday Reading 2018-07-20

Haven’t posted one of these for a while! It’s good to have some time back to be able to read/write.

My #SQLCareer Day–July 19

I’ve asked for #SQLCareer posts, and I haven’t done any. My job isn’t a data platform DBA or developer, but it is SQL related, so a glimpse of the nonsense I perform. I’m asking for more posts, so a note at the bottom.

Getting Schooled by Brent

Earlier this year Brent Ozar invited me to attend some of his online classes for free. Free is good! Training is good! I signed up with a few thoughts in mind:

SQL Solver

A few months back I ran across this article for checking semantic equivalencies of queries. That’s interesting, from the perspective of someone that has once or twice rewritten a query to be faster and then discovered it was subtly different. I don’t think we have the equivalent. We can compare… Read more

Data Masker for SQL Server and Temporal Tables

A customer had a question recently about using Data Masker for SQL Server and temporal (or system versioned) tables. I decided to make a quick demo that will show how this works.

Data lakes and swamps, oh my

I was lamenting to my friend and fellow MVP Shamir Charania (blog | Twitter) that I didn’t have a topic for this week’s blog post, so he and his colleague suggested I write about data lakes, and specifically Azure Data Lake. What is a data lake? This is what Wikipedia… Read more

Specifies that the restore operation loads the information into the msdb history tables. The…
