A Fine Slice Of SQL Server
I continue a series on data virtualization in SQL Server 2022:
Several years ago, I wrote a blog post on how to insert data into Azure Blob Storage from SQL Server using PolyBase. That technique used PolyBase V1: the Java connector for Hadoop. With SQL Server 2022 eliminating that connector, we’re going to learn the new method.
This is one of the larger practical differences in data virtualization with SQL Server 2022.

RStudio Connect is a platform which is well known for providing the ability to deploy and share R applications such as Shiny apps and Plumber APIs as well as plots, models and R Markdown reports. However, despite the name, it is not just for R developers (hence their recent announcement). RStudio Connect also supports a growing number of Python applications, API services including Flask and FastAPI and interactive web based apps such as Bokeh and Streamlit.
In this post we will look at how to deploy a Streamlit application to RStudio Connect. Streamlit is a framework for creating interactive web apps for data visualisation in Python. It’s API makes it very easy and quick to display data and create interactive widgets from just a regular Python script.

Comments closedManvendra Singh takes a backup:
This article will explore backup options available in the Azure Cosmos DB service. Backups are very important to safeguard our data in case of data corruption, data deletion, system failure, or any unforeseen circumstances like DR. We have planned, configured, and managed it for our on-prem databases whether it is SQL Server, Oracle, DB2, or system files on various machines. DBAs and Infrastructure admins have ensured to keep a backup of all these systems to safeguard their data. Similarly, we must also secure our data hosted in a cloud environment for any services whether it is Azure VMs, Azure SQL, Cosmos Db accounts, or any other services. Today we will talk about backup options available to secure cosmos DB databases and their contents.
Click through for those two options.

A lot of DBAs aren’t as familiar with Oracle DataGuard as many would think. Even though it’s a phenomenal product, they may have never used it, so knowing the ins and outs of the best Oracle product to use with Oracle on Azure is important.
I highly recommend the following documentation and guidelines from Oracle. The Product team in charge of DataGuard is fantastic at Oracle, so why go anywhere else to learn about this?
If you are in the situation where you’re thinking about moving your Oracle servers to Azure, this is a good starting point.
Comments closedWe received some support cases when customers encounter the error below while trying to add an AAD security group to their Azure SQL Database or Azure SQL managed instance. In this blog article, we will be listing a few points to be checked to troubleshoot this error and can help you to identify the cause.
Msg 33130, Level 16, State 1, Line 1
Principal ‘XXXXXX’ could not be found or this principal type is not supported.
Read on for several reasons why things might be going wrong.
Comments closedI take a look back at the past and forward to the future:
PolyBase used to connect to Azure Blob Storage. Specifically, you could use the
wasbs://protocol and connect to Azure Blob Storage over WebHDFS. Here’s an example of an external data source which would work for SQL Server 2016 through 2019:
SQL Server 2022 changes its mechanisms around Azure Blob Storage a little bit, though I think the changes are sensible.
Comments closedImke Feldmann starts a new series:
If you want to traverse organisational hierarchies, walk through nested folder structures or create nested Power BI metrics from an Excel table for example, you need some sort of recursive logic. In this article I will introduce you to the basic method of recursive flows in Power Automate. In upcoming articles I will share some of the flows for the above mentioned use cases.
Read on for an intuitive understanding of what recursion is as well as how you can implement it in a Power Automate flow.
Comments closedRajendra Gupta needs to deploy a SQL Server container:
This article uses Azure Kubernetes Service (AKS) to deploy and manage the Kubernetes cluster. It is a fully managed service that offers serverless Kubernetes with integrated CI/CD solutions, enterprise-grade security, and governance.
You can navigate to https://azure.microsoft.com/en-in/services/kubernetes-service/#overview and try Azure Kubernetes Service (AKS).
Read on for an overview of Azure Kubernetes Service and how you can get a SQL Server on Linux container running atop it.
Comments closedI have some fun integrating the Cosmos DB Core API with PolyBase:
PolyBase comes with a few built-in drivers, including Oracle, Teradata, MongoDB, and SQL Server. For everything else in the 2019 “style” of things, there is a generic ODBC route. In this route, you need to obtain a valid ODBC driver, configure it, and let PolyBase know how to access data from that remote source.
Cosmos DB’s Core API just happens to have a working ODBC driver, so the first step is to grab the relevant version of that driver and install it on the machine running SQL Server.
Read on to see how it works and how you can get around some initial pain points. As a quick note, this only works with SQL Server on Windows, as SQL Server on Linux does not support generic ODBC drivers with PolyBase.
Comments closedMichal Bar has a couple of posts for us. First, updates to the desktop app Kusto Explorer:
Query Automation allows you to define a workflow that contains a series of queries with rules and logic that govern the order in which they are executed. Automations can be reused, and users can re-run the workflow, to get updated results. Upon completion, the saved Automation produces an analysis report, summarizing all queries results with additional insights.
Then, updates to the ADX web explorer:
It is now possible to embed Azure Data Explorer dashboards in 3rd party apps. This comes on top of allowing embedding of the Monaco editor in 3rd party apps.
Dashboard embedding allows you to easily share data with your customers in a way that allows them to interact and explore it.
Using the various feature flags, you can control the exact controls that will be part of the embedded dashboard experience. For example, you can decide to remove the share, and add connection menu items or others.
To learn more about dashboard embedding, please read this doc Embed dashboards
Read on for the full changelog.
