15 Short Code Snippets

Published 2021-10-14 by Kevin Feasel

Chad Baldwin goes the extra mile:

I’m excited that this will be my first time participating in a T-SQL Tuesday topic!

Most of my time is spent writing T-SQL, PowerShell and working in the PowerShell terminal, so that’s how I’ll split the post up.

I had to cut it short otherwise this post would be a mile long. If you’re interested in seeing more quick tricks, SQL Prompt snippets, etc, please leave a comment and let me know and I can do a Part 2 in the future.

Adding Debug Logic to T-SQL Procedures

Published 2021-10-13 by Kevin Feasel

Deborah Melkin does not take kindly to bugs:

I often find that I have to write complicated stored procedures where I need to check things as I go along. My go-to for using this snippet is when I write stored procedures that use dynamic SQL. You’d be surprised (or not) at how often I have had to do this over the years. There’s been functionality where the user gets to choose the columns being used, rewriting ORM data layer “catch-all” queries to improve performance, and cross database queries where the name of the database may not be the standard name (think development and QA databases living on the same SQL instance.)

Click through for an example of where the @Debug parameter pays off. My recollection was that, for really long NVARCHAR(MAX) strings, running PRINT by itself might cut off the code after ~4000 characters, but that could be a historical recollection.

Repurposing Helpful Scripts

Published 2021-10-13 by Kevin Feasel

Deepthi Goguri re-shares some helpful scripts:

For the past couple of years as a DBA, I migrated several databases and used many handy scripts that helped me made my work easier. These scripts may be simple but if you have a migration project involving several SQL Servers with some hundreds of databases, test and production database migrations becomes tedious. I would like to share some of then here which you might already known them very well.

Short Query Store Queries

Published 2021-10-13 by Kevin Feasel

Mala Mahadevan has a few short-ish Query Store scripts for us:

I use Query Store a lot where I work – and I’d like to share queries I use on Query Store DMVs that I find incredibly useful.

My favorite is one below, which I use to see stored procedure duration. It comes with other information including plan id, start and end time – all of us help me see red flags right away if there is any query not performing as well as it should.

Building a DBA Database

Published 2021-10-13 by Kevin Feasel

Andy Mallon wants a database all of his own:

I’ve written about my DBA Database quite a few times. Some of the code in that database is written recently, and some of it was originally written a decade ago. Regardless of how old it is, or how good of a DBA I was when I wrote it, these little scripts are life-savers, and they are always at my fingertips.

And Andy has made them available to your fingertips as well. And the rest of your hands, I suppose.

Searching T-SQL Objects

Published 2021-10-12 by Kevin Feasel

Rob Farley has a quick script to find references in SQL Server:

As a consultant, the kind of work that I do from customer to customer can change a bit. Sometimes I’m reviewing people’s environments; sometimes I’m performance tuning; sometimes I’m developing code or reports or cubes; sometimes I’m writing T-SQL, but it’s often DAX or PowerShell.

Sharing Short Code Examples

Published 2021-10-05 by Kevin Feasel

John McCormack lays out the parameters for this T-SQL Tuesday:

T-SQL Tuesday this month is going back to basics and its all about code. I’d like to know “What are your go to handy short scripts”?

What are those little short bits of code that you can’t live without? I’m talking about little snippets that are only a few lines, that you may even have memorised. It could be T-SQL, PowerShell, Python or anything else you use day to day.

Click through for two of John’s.
