Stellar Repair: A Review

Grant Fritchey reviews a product which attempts to repair corrupted SQL Server databases:

Let’s start with the most important piece of information you need: it works.

The software itself is really simple to use and just does what you need, repairs your corrupted SQL Server instance. On that alone, I can recommend the tool.

However, there are a few gotchas I ran into along the way. Mostly, little stuff. It’s things a little polish in the UI and some clean up around language could help out. Don’t get me wrong, I’m happy with this software. It worked. It’s just how it works that we should talk about.

The Origins of SentryOne Plan Explorer

Jason Hall gives us a bit of history:

Greg saw a need in his own work, and I was seeing a need in the field with our customers, for a way to go beyond identifying high-impact queries. DBAs and developers needed a way to tune queries surfaced by SentryOne SQL Sentry’s Top SQL without fiddling with a lot of extra tools to get there. We were already building integration with SQL Server Management Studio (SSMS), which included graphical query plans, so the original thought was to extend that integration from SentryOne with a link that opened plans in SSMS from Top SQL in SQL Sentry.

It seemed like an elegant solution that would allow us to reuse some code, but it wasn’t long before Brooke Philpott discovered that we wouldn’t be able to get what we needed this way. That particular part of SSMS wasn’t exposed to us in the manner we needed. Par for the course, we weren’t going to let that stop us from filling the need. Greg and Brooke dug into the problem to discover a mix of documentation, flow controls, and ingenuity that would provide the foundation for building our own query plan visuals.

Read on for the story and a bit about how the product has morphed through the years.

mssql-cli Generally Available on MacOS and Linux

Alan Yu announces the general availability of mssql-cli outside of Windows:

We are excited to announce that mssql-cli is now generally available on macOS and Linux.

mssql-cli is an open source and cross-platform command-line tool (CLI) to manage SQL Server on-prem and on the cloud. We are a proud member of the dbcli family of open source command line tools to manage relational databases.

If you are a user of sqlcmd, you will love the interactive and modern design components in mssql-cli. With this release, you will also be able to use mssql-cli in non-interactive scenarios such as scripting and automation. Read on to learn more about how mssql-cli will help improve your productivity through a modern CLI experience.

If you love the command line (or simply need to SSH into a box from time to time), give this product a try.

Poor SQL Formatter’s SSMS Plugin

Dave Bland shows us the Poor SQL formatter for SQL Server Management Studio:

So what is PoorSQL Formatter?  Well, as you probably know, formatting is very important when writing T-SQL code.  While we try to format our code as we write it, sometimes the code we need to review was written by someone else and maybe doesn’t follow formatting standards. This is where PoorSQL Formatter will come in handy.  It will help us take the poorly written code and format it in a manner that is more in line with T-SQL formatting best practices.  The best part, it will do the formatting in seconds.

I’ve used that website many a time. It’s not as detailed as I want it to be, but if you just need a quick and dirty way to format a query so that it’s understandable, this does the trick.

The Basics of tSQLt

Jess Pomfret walks us through the basics of tSQLt:

Getting started with tSQLt is really easy- you download a zip file, unzip the contents and then run the tSQLt.class.sql script against your development database.

There are a couple of requirements, including CLR integration must be enabled and your database must be set to trustworthy.  These could open up some security considerations, but for my development environment it’s no issue.

This is where I’d say putting the database in a container would be extremely helpful, as then you can destroy it afterward. I’m not sure if that’d work, as SQL Server on Linux doesn’t support unsafe or external access assemblies (and I’m not sure what tSQLt requires there).

Replaying Workloads to a Different Database with WorkloadTools

Gianluca Sartori takes us through workload replay ability in WorkloadTools:

One of the features I was asked to implement for WorkloadTools is the ability to replay commands to a database name different from the one recorded in the source workload.

This is something that I had been planning to implement for a while and it totally makes sense. Usually, you have two identical environments for the workload capture and replay, both with the same databases. Sometimes it makes sense to have two different databases as the source and target for the workload, for some particular reasons: resources constraints, ease of testing and so on.

WorkloadTools now supports replaying commands to a different database, using the DatabaseMap property of the ReplayConsumer.

Setting this up is pretty simple, though Gianluca does lay out a caveat.

sqltxls Now Supported Cross-Platform

Randolph West has made sql2xls work on Linux and MacOS:

Last year I released sql2xls, a free open-source tool which lets you throw a bunch of scripts into a folder, run them automatically against SQL Server and get the results back in a nicely-formatted Excel file, one tab per script.

A year later, I am happy to announce that the tool now runs cross-platform. You can compile and run it with .NET Core 3.1 LTS to run on Windows, macOS, and Linux. It uses the new Microsoft.Data.SqlClient library from NuGet, as well as the latest beta of ClosedXML.

Read on for a few more tips and go check the project out.
