Take Any from KQL

Robert Cain isn’t picky:

The take_any function is a random row generator. Based on the parameters passed it, it will select a random row from the dataset being piped into it. It also has a variant, take_anyif, we’ll see both in this post.

Note that take_any was originally called any and was renamed. While any still works, it has been deprecated and you should now use take_any.

As always, Robert shares plenty of examples of how the operator works, so check it out.

The Power of Date Truncation

Magda Bronowska rounds to the nearest minute:

From MS Learn:

DATETRUNC() function returns an input date truncated to a specified datepart.

On the surface the work similarly to DATEPART(), however that function returns integer values, opposed to the dates returned by DATETRUNC() (we will see that better in the example below).

Read on for plenty of examples of this, as well as two more syntax updates in SQL Server 2022.

Distributing Azure Costs by Cost Centers, Divisions, and Projects

Pranab Paul divvies up the costs:

While working on various customer and partner facing roles, I felt the necessity of a simple and flexible solution to align Azure Cost to the customer’s organizational structure. “Project Bose” is a fully operational prototype derived from the same thought process. This is a side project I am working on during my leisure time. I found various customers derived similar solutions in-house, and there are ISV solutions as well. But there are a few fundamental differences between “Project Bose” and all the other solutions I found. “Project Bose” has a flexible backend and hence any changes in organizational structure can easily be implemented on it without disruption. It is also independent of using Resource Tags, which gives it the opportunity to remain non-vulnerable to erroneous values injected intentionally or non-intentionally by IT-Ops.

Pranab didn’t include a link to the GitHub repo, so here it is.

The Benefit of IS DISTINCT FROM

Rob Farley enjoys the syntax:

This month, Deepthi Goguri (@dbanuggets) asks us about our favourite new feature in SQL Server 2022 or Azure. And while there are always a few, I’m going to write about why I have a particular fondness of “IS [NOT] DISTINCT FROM“, despite the fact that it’s overly wordy and the functionality isn’t actually new at all.

People understand my point that it’s a little wordy. Typing “IS NOT DISTINCT FROM” instead of “=” doesn’t sound fun to anyone, and I think “==” or “IS” ought to be fine. The fact that the functionality isn’t new… well that statement seems to raise a few eyebrows.

Read on for Rob’s take on what IS DISTINCT FROM (and its negative cousin) actually do and what performance-killing alternative people used prior to that.

Trying out Azure Synapse Link for SQL Server 2022

Kevin Chant looks at Azure Synapse Link for SQL Server 2022:

My first topic is about a new feature that covers both SQL Server 2022 and Azure. Which is Azure Synapse Link, or to be more precise Azure Synapse Link for SQL Server 2022.

I have been doing various tests with this feature recently. Which has led to some interesting blog posts about Azure Synapse Link for SQL Server 2022.

Read on for a few more thoughts, as well as deployment scripts via Azure DevOps and GitHub Actions.

Error Handling with OPENROWSET

Deborah Melkin handles missing servers with aplomb:

OPENROWSET is a functionality that allows you to access data sources outside your current server. This could be reading from an Excel file or calling another SQL Server instance. You’re able to treat that other data source as record set, or derived table, and work with the rows returned as you would a local table. One reason you may want to do this is that you need to use a stored procedures to query data from other servers and bring the data together, effectively creating an ELT (Extract – Load – Transform) process without having to use SSIS or Azure Data Factory (ADF).

Read on to see how OPENROWSET() works, what happens if you try to access a remote server which doesn’t exist (or times out), and how you can capture that error message in a CATCH block—something that is not possible to do by default.
