Comparing Snowflake vs SQL Server E-Mail Configuration

Published 2024-10-24 by Kevin Feasel

Kevin Wilkie sends two e-mails:

Today, I want to talk about all the effort that goes into setting up the ability to email in SQL Server and Snowflake.

First is our old friend – SQL Server. I’ll leave this one to the experts at Microsoft. As has been the case over the last few years, they have some great documentation at Learn.Microsoft.com – especially when it comes to SQL Server.

I don’t know anything about sending e-mails via Snowflake (other than what Kevin mentions here), though I imagine a lot of the difference in complexity is that SQL Server allows arbitrary SMTP selection and requires an existing SMTP server.

Configuring Database Mail in Azure SQL MI

Published 2024-10-23 by Kevin Feasel

Andy Brownsword sends an e-mail:

SQL Agent jobs allow us to schedule and automate tasks on a SQL Server instance. Crucially, when things go wrong we need to know about them. That’s why we use notifications.

Setting up Operators and job Notifications is as expected on a Managed Instance. However, when it comes to sending the notifications we may have a challenge, as shown in the SQL Agent Error Logs:

Building an Impact Analysis Process

Published 2024-10-18 by Kevin Feasel

Marc Lelijveld needs more than the minimum impact analysis:

Imagine you have a semantic model in the Power BI Service (or Fabric if you will), and you’re about to make a breaking change to this semantic model. How do you inform your end users? How do you tell them about this change? In this blog I will zoom in to options you have in the interface that will help you to reach out to your users, looking at different aspects from other reports in Power BI, but also more complex the users that connect via Analyze in Excel.

Click through for the use case, why the built-in impact analysis option for Power BI isn’t sufficient, and what you can do to flesh it out.

Migrating to Azure PostgreSQL Flexible Server from Single Server

Published 2024-10-18 by Kevin Feasel

Josephine Bush performs a migration:

Why Migrate to Flexible Server?

  • High availability and disaster recovery: Flexible Server provides higher availability with zone-redundant architecture.
  • Customizable maintenance windows: More control over when updates and maintenance tasks occur.
  • Performance improvements: Fine-tuned scaling and performance adjustments without downtime.
  • Enhanced security: With VNet integration and more advanced networking options.

Read on to learn more about by when you have to migrate and how you can perform the migration.

Converting Audit Files to CSV via Read-SqlXEvent

Published 2024-10-16 by Kevin Feasel

Patrick Keisler finds a work-around:

Reading the contents of an audit event file can be accomplished using either Management Studio or the T-SQL function, sys.fn_get_audit_file. However, sometimes a customer may want to use a third-party tool to read and aggregate audit records, and some of those tools do not have the ability to read the binary audit file. In that case, the customer will just use sys.fn_get_audit_file to write the audit records to a database and then use the third-party tool to ingest those records from the database.

What if that third-party tool cannot even read from SQL Server? That happened to me recently where the only option was to read from a text-based file.

Read on for Patrick’s solution to the problem and a real pain point you’ll find along the way.

Capturing Database Object Changes in SQL Server

Published 2024-10-14 by Kevin Feasel

Sebastiao Pereira creates a trigger:

Data Definition Language (DDL) is a group of SQL statements that can be executed to manage database objects. The idea is to create a database trigger that tracks and logs all changes to database schemas, including modifications to stored procedures, tables, views, and other schema objects and storing any event in one table.

Read on for an example of a database-level trigger. These are much less likely to cause performance problems compared to table-level triggers, though you could certainly cause issues via poor trigger definition.

Querying Audit Log (.xel) Files in Azure SQL DB

Published 2024-10-14 by Kevin Feasel

Tanayankar Chakraborty reads an audit log:

A recent issue was brought to our attention that customers could not query .xel log files in an Azure SQL DB using t-sql command. The customers complained that when they ran the command, they received column headers but no content whereas they know that there is content in the logs because they were able to open them with SSMS using Merge Extended Event Files. Here was the T-sql command used by the customer:

select * from sys.fn_get_audit_file (‘https://mydbastorage.blob.core.windows.net/sqldbauditlogs/servername/dbname/SqlDbAuditing_Audit_NoRetention/*.xel’, NULL, NULL);

Click through for the solution, which came down to two separate issues.

Client Diagnostics in Cosmos DB

Published 2024-10-10 by Kevin Feasel

Arthur Daniels digs into diagnostic data:


This topic keeps coming up with my customers so the purpose of this blog post is to keep all the useful information in one post. Think of this post as a consolidation of different pieces of information. If you’re stuck on what “pipelined”, “created”, or “transit time” means, you’re in the right spot.

We are not talking about Diagnostic Settings/Log Analytics in this post, I’d describe those as server-side rather than client-side diagnostics. They are useful in different ways, our client diagnostics will help us understand the path that a request takes from the application to Cosmos DB and back, along with any latency on that path.

Note: before we get started, check to see if you’re using Direct or Gateway mode. Ideally sending your requests Direct mode in the .NET or Java SDKs will usually result in faster requests.

Read on to see how to retrieve and interpret this diagnostic data.

Fixing Missing SQL Agent Jobs Post-Migration

Published 2024-10-08 by Kevin Feasel

Lee Markum is looking for that lost shaker of SQL Agent jobs:

I’ve been doing migrations fairly continuously for the past 18 months. PowerShell has been my primary mechanism for many parts of the process, including copying jobs from the source SQL Server to the target. That has worked almost without incident each time. However, recently, an app team noticed that there were SQL Server Agent jobs missing on their new 2022 SQL Servers.  Because the first couple of missing jobs also existed on their Development environment, they were able to recreate those jobs in production. They naturally expressed concern that other jobs may be missing.

Read on for Lee’s process, including the solution.
