Data preparation has become so easy and potent in Excel and Power BI. The user experience of the Query Editor of Power BI and Excel (Power Query Add-In, or Get & Transform in Excel 2016) is extremely rewarding. It changes…
Today I am going to spend some time trying to convince (and demonstrate to) Excel Power Pivot users that it is easy and valuable to learn some simple SQL code. SQL is one of the easiest languages I have ever…
My last 2 blog posts have been about data compression – that theme continues today. In December I blogged about the basics of compression and impacts that columns have on file size and did some testing with randomised data. In…
I was relaxing during my vacation thinking some more about column compression in Power Pivot. One of the main things to know about compression is that a high level of cardinality is your main enemy (ie a large number of…

Guest Post by Andrew Todd
Intro by Avi: Andrew has been a part of PowerPivotPro family for a while now and has been doing wonders for the clients he has been working with. You have probably heard Rob talk about the “Data Gene”, well Andrew is the ideal specimen for that breed.
Recently I had worked with a client where we spent quite some time just trying to figure out how to connect Power Pivot to their Oracle database. Andrew here lays it all out in simple step by step approach. Andrew’s got a lot of wisdom to share and you should all look forward to more posts from him. Take it away Andrew…
The amount of data around us is staggering. Statistics citing the amount of data being generated daily describe it in terms of exabytes (1 exabyte is 1 BILLION gigabytes!) In fact, the amount of data generated daily now exceeds the entire storage capacity of the entire world in 1986!
In a world with that much data, we’re lucky to have tools like Power Pivot and Power Query that offer easy connection to data sources that just sort of … clicks! However, if you’ve tried connecting to an Oracle database in Power Pivot you might have had some trouble. Fear not, here’s how you can make your Oracle database connections click just like all the rest!
Why aren’t my Oracle connections ‘clicking’?
For Excel pros, Oracle databases are a bit different, because there are a few key connection enabling components that are not automatically included with most users’ setups:
1.) Connection details – for Oracle databases, the connection details are included either in the connection string itself (EZConnect) or in a flat file called TNSnames.ora. Don’t worry, it isn’t as complicated as it sounds!
2.) Oracle data providers – You can think of these as the communication link between Power Pivot and the Oracle database.
Make a Call to your DBA for some details!
Before you attempt to connect to your Oracle database, you’ll need to contact your friendly Oracle DBA for the following information:

Autorefreshes Your Power Pivot Workbook as Frequently as Desired, Auto-Publishes to Any Location, and Now Sends Email Notifications of Success/Failures – With Attachments!
Our Gift to the Community: New, Improved, and Free
The team has added several new features in the latest version of Power Update. One of them (email notifications that optionally attach the updated workbook or PDF-ified version of the workook), is pictured above.
But the biggest new “feature” is that there’s now a 100% free version. Go ahead and download it from the link below, and start using it today.
It will work forever – no trial expiration – and will never require payment.
It will be installed and working in less than five minutes. Have fun, and if you have any troubles, report those on the Power Update Forum.
“Why Free? What’s the Catch?”
Simply put, we want everyone to have it. Everyone. It’s a game changer. It will lead to more Power Pivot / Power BI adoption and overall goodness, which is very much something we want.
The only limitation in the free version is that it will only schedule one workbook. Every last feature is available – email, PDF attachments, publish to SharePoint and even SSAS Tabular.
So if you’ve only got one important workbook, you can use the free version forever. A lot of people will run that way, and we’re ok with that. If you someday end up with more than one workbook that needs refresh, you can opt to purchase the full version, which can schedule as many workbooks as you want.
“Wait, Can’t I Cheat That With Multiple Computers?”
***Update #1: a Free Version of Power Update is now available. More info here.
***Update #2: There is now a forum for Power Update questions, located here.
Intro from Rob: I’m what you might call a “gift horse optimist” – strongly positive outlook, but when the hoped-for thing finally arrives, I find myself closely inspecting it, testing it, before I trust it enough to advocate it to others. I went through this same process with Power Pivot itself – I “saw” its gamechanging power in 2010, but it was a full eighteen months before I finally dropped all disclaimers and just started calling it far better – period – than anything we’ve had before.”
Similarly, I’ve long known that Power Update would be a MAJOR win for us in the Power Pivot and Power BI communities. But I am willing to advocate it now only because I’ve watched others – like Scott, and Tim below – use it successfully, in production environments, in recent months. (Also see my post last week “introducing” Power Update in case you missed it).
Take it away, Tim…
I first found out about Power Update two months ago via a LinkedIn post by Christian Floyd.
It took me a while to realize that he wasn’t talking about a theoretical future idea, but an actual product, something that exists today. Click the picture below to see the entirety of my foolishness. It wasn’t until I talked to him directly that I realized what Power Update really was and I was immediately interested.
He got me a beta version of Power Update and I began testing it at the company I work for: a manufacturing company in Cleveland, OH called The Robbins Company.
We started using Power Pivot at The Robbins Company back in 2013 and I wrote about our experience on this blog (click here).
