A Fine Slice Of SQL Server
Tomaz Kastrun pays for 20% of ticket prices because he’s always on the edge:
What you need to do is simply run:
python -m pip install notebook --pre --upgradeAnd with this prerelease version of the Jupyter notebook, you have in addition several options to enhance your workspace.
Besides the refreshed outlook, what else is available in this version?
Check out what’s in this version of Jupyter.
Comments closedAnna Hoffman brings us tidings:
Emily Lisa kicked it off by telling us about the latest Azure SQL Database product updates including Azure SQL maintenance windows, zone redundancy for SQL Hyperscale, and configurable backup storage redundancy for SQL Hyperscale.
Dani Ljepava from the Azure SQL Managed Instance product team came on to share a range of new features announced at SQL Bits now available in public preview: Link feature for Managed Instance, data virtualization with ADLS, Advanced notifications for planned events, Hybrid Service Broker, Windows authentication for Azure AD Principals, and the general availability of Maintenance windows. Watch the episode to see a special look at Link feature for Managed Instance!
Pam Lahoud also came on to talk about about the latest improvements that help you manage your SQL Server in Azure Virtual Machines, including the newly released SQL best practices assessment, all available to you by installing the free SQL IaaS Agent extension!
Read on for plenty more links and updates.
Comments closedRajendra Gupta builds a simple Azure Function:
As a Platform as a Service (PaaS) service, Azure SQL Database enables developers to deploy SQL Database in Azure Cloud without managing the infrastructure. We use SQL Server Agent to schedule jobs to run at a specific schedule in an on-prem SQL instance. However, Azure DB does not have agent functionality.
There are multiple ways to schedule job or batch processes in the Cloud. You can explore the Azure automation series for executing scripts using Azure Logic apps and automation runbooks.
This article focuses on the Azure functions for scheduling a job for Azure SQL Database.
Read on for the process.
Comments closedKendra Little searches for timeouts:
Here are some basics regarding query timeouts for SQL Server, Azure SQL Database, and Azure SQL Managed Instance:
– Execution timeouts are NOT set or enforced by the database engine. It is happy to wait for your query to run or for your transaction to be open for hours, days, or years, until you commit, cancel, or get disconnected.
– Timeouts are set by the calling application. If you don’t explicitly set a timeout on your connection string, there is generally a default timeout that is used. Often, this is 30 seconds for query execution timeouts.
– Connection timeouts are different than execution timeouts. If you see a connection timeout, often this is a firewall or network issue preventing you from connecting to the database – or perhaps it’s even offline. Execution timeouts are when the calling application doesn’t want to wait any more for a query to complete.
Kendra shows how to generate an execution timeout and how you can use Query Store to find them. And Kendra’s post got Mark Freeman to write a blog post so that’s also worth something.
Comments closedErik Darling goes scalar hunting:
This is awful. It really is. It’s so awful. These operators skated by undetected for years. Acting so innocent with their 0% cost.
Subprime operators, or something.
In this post, I’m going to show you how compute scalars hide work, and how interpreting them in actual execution plans can even be tricky.
I’m now imagining Erik as the Steve Irwin of the query tuning world. And it’s kind of working for me.
Comments closedJeff Iannucci has a follow-up for us:
This is a follow up post to the previous one about tables with no records using data space, with the idea coming from twitter of all places. Sometimes on twitter the conversations kill, but after reading that post my friend Chris Wood suggested writing something to FIND those tables.
Which is a solid idea, so let’s get to it. No time to wait too long.

Comments closedImke Feldmann translates an Excel function to Power Query:
While there is a native YEARFRAC-function in DAX that you can use to calculate year fractions, sometimes you might just need it in Power Query. The function I’m presenting here has the same function arguments than its Excel-equivalent. Its 5 different modes require some advanced calculations. Fortunately I found a great resource on how to calculate it here. So my version here is basically a direct translation into the M-language.
