A Fine Slice Of SQL Server
Christian Lorentzen makes a swap:
With its newest release 1.1.0, the Python package model-diagnostics got the concept of a plotting backend. Before this release, all plots were constructed with matplotlib. This is still the default. But additionally, the user can now select plotly, if it is installed.

In the world of statistics and data analysis, understanding and accurately estimating the parameters of probability distributions is crucial. One such distribution is the chi-square distribution, often encountered in various statistical analyses. In this blog post, we’ll dive into how we can estimate the degrees of freedom (“df”) and the non-centrality parameter (“ncp”) of a chi-square distribution using R programming language.
Read on to learn more about the process of estimation while I grumble something about Bayesian analysis being better.
Comments closedVlad Drumea blames the intern:
This is pretty useful if you’ve inherited a SQL Server instance running on Linux, but the last person™ didn’t bother saving the sa password in your teams password manager vault.
Or, if you’re like me, and spin up test instances with random passwords for sa that you don’t bother saving anywhere.
Click through to see where you can find out how to reset the password, and then the actual mechanics of password reset.
Comments closedAaron Bertrand makes use of an ordering:
In my previous post, I showed how to borrow a snake draft concept from fantasy football, or a packing technique from the shipping industry, to distribute different portions of a workload to run in parallel. In the previous example, we determined a distribution order for databases based on size – though you can rank by literally any attribute (or combination of attributes). Once we’ve determined how to build out this order, we may want to store that data somewhere because, sometimes, the source of that data is not directly accessible.
Read on for tips on storing the results in a table, querying the results, and using them to drive SQL Agent jobs.

Microsoft Fabric offers an end-to-end SaaS analytics solution; however, the world is using all kinds of data sources in its implementation. Mirroring is a new functionality in Fabric that allows customers to keep their data wherever they are, but then they can use Fabric analytics solutions with the same speed and performance as if their data were in Fabric. Best of all, this won’t cost extra. If you wonder what it is and how it works, read this article.

Alerting is an important monitoring task for any ETL process. Azure Data Factory can integrate with a generic Azure event framework (Azure Monitor) which makes it somewhat unintuitive for ETL monitoring. You can set up and change the alerts using the ADF Monitoring hub.
Read on for five pieces of advice, in particular, covering how to set up one of these alerts.

There are several approaches to work with Microsoft Purview entities programmatically, especially when needing to perform bulk operations such as documenting a large number of tables and columns dynamically.
This article shows how to use the Python SDK for Purview to programmatically document Purview table columns in bulk – assuming there are many tables and columns that needed to be automatically documented based off a reference tables – as in this example, the data dictionary maintained in Excel.
On the other hand, Purview REST APIs can be used to natively work with the REST APIs whereas the Python SDK for Purview is a wrapper that makes it easier to programmatically interacts with the Purview Atlas REST APIs in the backend.

Comments closedAndy Brownsword forgets something at home:
Within SSIS you can make use of custom components which aren’t present out of the box. An example of some would be the Azure Feature Pack if you’re working with cloud resources.
These will let us use features not available natively. They can also provide a challenge down the line when we come to deploy changes to the project.
Here we’ll look at an example of this challenge, how to troubleshoot, and ultimately resolve the issue.
Read on for the scenario and fix.
