Implementing Multiple Retries in Powershell

Published 2023-06-16 by Kevin Feasel

Jose Manuel Jurado Diaz has a script for us:

We often encounter support cases where our customers leave the query execution timeout value at its default. In certain situations, we may find that when this value is reached, the application reports an error and does not continue. In this case, I would like to share an example implemented in PowerShell that allows incrementing the command timeout value up to 5 attempts, with a 5-second margin in each operation.

My recommendation here would be to use Polly instead, as it built in support for exponential backoff and more complex retry logic. Adam Driscoll has a Powershell wrapper called pspolly, which may also prove helpful.

Reviewing Always Encrypted Queries with Extended Events

Published 2023-06-16 by Kevin Feasel

Matthew McGiffen takes a look:

In previous posts we’ve looked at a number of aspects of Always Encrypted and how it works. I think it’s very useful to understand how it actually works in practice, so in this post we’re going to look at what happens in the background when you execute a query.

I’m continuing on from the examples in the last few posts on this subject. So if you want to repeat the examples for yourself you’ll need to have followed steps from Setting Up Always Encrypted and Executing Queries Using Always Encrypted.

Read on to see what actually happens when you perform a simple INSERT or SELECT operation and there are Always Encrypted columns involved.

Changing Visual Titles on Filter with DAX

Published 2023-06-16 by Kevin Feasel

Allison Kennedy has a new title:

Today’s post is a short one with a video to demonstrate what I have learned. I’m a big believer in providing your end user with as much information as possible. Someone new should be able to pick up the report and understand it without needing to get a degree in Power BI or go digging through your company’s intranet to learn what’s what. 

One of the neat features that Power BI provides, is the ability for any visual to act as a filter or ‘cross-filter’ to other visuals. This provides us with comparative values and highlighted bars, but Power BI tooltip just says ‘highlighted’, which isn’t very helpful.

Click through for a bit of DAX code which can help with that, as well as a video demonstrating how it all comes together.

Drillthrough Support in Power BI Paginated Reports

Published 2023-06-16 by Kevin Feasel

Dan English is excited:

Last month there was a new update that has been made that provides support for drillthrough report actions in the Power BI service (Microsoft Fabric)! Those of you who are familiar with SQL Server Reporting Services (SSRS) know what a great feature this is to include in your reports to allow users to jump to another report for additional information such as detail level report and even allow the ability to pass the context (parameters) to the report.

Drillthrough was a big item that might have been a blocker for some companies preventing them from migrating from on-prem SSRS or Power BI Report Server (PBIRS) to the Power BI, well not anymore:)

So how does this work? 

Read on to learn more, including something which is in Power BI paginated reporting but not SSRS.
