T-SQL Tuesday #104 Roundup

Published on: 2018-07-17

This month’s T-SQL Tuesday topic asked “What code would you hate to live without?” Turns out you like using script and code to automate boring, repetitive, and error-prone tasks.

Thank you to everyone who participated; I was nervous that July holidays and summer vacations would stunt turnout, however we wound up with 42 posts!

Watch tsqltuesday.com for next month’s topic and consider signing up to host.

Watch this T-SQL Tuesday Roundup on YouTube.

Without further ado, here are this month’s entries sorted in random order:

  • Stuart Moore shares the history behind needing to automate restore testing and writing the SqlAutoRestores PowerShell module to help.  Nowadays his commands are found in dbatools.  Great example of how a project can evolve through the community.
  • Arthur Daniels shares his script to identify the key and included columns of indexes in a given table.
  • Glenn Berry shares his DMV Diagnostic Queries and the story behind how he started developing them back in 2006.
  • Jason Brimhall links to multiple scripts he’s shared in the past as well as a new script for remotely auditing server access to catch infilitraters red-handed.
  • Doug Purnell talks about how he uses database snapshots and shares some code for how he manages them.
  • Jay Robinson shares two C# extensions (shout to my fellow devs!): one to check an enum for a value and a second to cleanly handle the lengthy DBNull.Value syntax.
  • Drew Furgiuele shares how he scripts out his indexes to re-apply after snapshot replication.  He then writes very similar functionality using PowerShell in only 6 lines!
  • Tim Weigel shares which community scripts he uses regularly, as well as sharing his own scripts around replication, stored procedure execution information, and file manipulation.
  • Hugo Kornelis submitted two posts.  The first post shares sp_metasearch which helps with performing impact analysis and the second post follows up with an enhancement he’s made to Ola Hallengren’s database maintenance scripts to ignore backup BizTalk databases.
  • Andy Mallon shares his comprehensive script for checking database, file, data, log, etc… sizes.  Great explanations of his reasoning for writing the queries the way he did.
  • Dan Clemens shares his database search script with a switch that includes searching across agent jobs.
  • Jess Pomfret wrote a script that shows compression stats for database objects.  Wanting to run it against a whole instance (or across mulitple servers), she wrote a dbatools command to automate the process.
  • Kenneth Fisher shows us how he organizes his toolbox using an SSMS solution.
  • Rob Farley shares code he’s written to demonstrate the pain of using NOLOCK.
  • Steve Jones shares a procedure from Microsoft that he uses for transferring logins and passwords between instances.
  • Kevin Hill shares two scripts he uses for finding low-hanging index optimization fruit: one that finds queries performing heap or clustered index scans, and another that returns the top 5 missing indexes per database.
  • Michael Villegas learned that Azure SQL doesn’t allow you to graphically show user roles and permissions, so he wrote a script to query those details (works for on-premise SQL Server as well).
  • Nate Johnson shares scripts that identify if tables are being replicated, whether SSRS subscriptions executed, and how much space certain objects and files are consuming.
  • William Andrus shares how he uses his search script to find similarly named fields or all instances of a piece of text within a database.
  • Bert Wagner (me!) I share my template for generating dynamic table-driven code, making queries more adaptable to future changes.
  • Rudy Rodarte shows us a script he uses for iterating over a date range to use for executing date based queries.
  • Brent Ozar admits he can’t live without sp_Blitz, but this month he shares a script for checking how much plan cache history exists on a server.
  • Jeff Mlakar offers a solution for taking all databases on an instance offline (and then back online) again.
  • Erik Darling offers a solution for constructing dynamic SQL so that his MAX variables don’t get truncated.  He also links to a script for printing long strings in SSMS.
  • Chrissy LeMaire takes the hard work out of instance to instance migrations by sharing her single-line dbatools command that will do it all for you.  She also shares how dbachecks automates manual checklist work.
  • Glenda Gable mentions two procedures, one that is a high performance cursor rewrite and one  that is a robust log shipping solution.
  • Aaron Bertrand shows us how he discovers undocumented SQL Server features by comparing new builds to the previous versions.
  • Ryan Desmond writes about his post-install confirguration process and shares code he runs to customize Ola Hallengren’s maintenance scripts for his environments.
  • Josh Simar shares his database file size code that is optimized for “very large databases” that span multiple files and filegroups.
  • Sander Stad discusses the importance of sharing code and offers a few dbatools commands that he’s contributed to or authored around backup testing, log shipping, and SQL Server Agent manipulation.
  • Andy Levy wrote an SSMS snippet to generate a cursor.  Before you chew him out though, he has some really good uses cases for needing to use them.
  • Andy Yun reveals what’s in his T-SQL toolbox and explains his organization strategies for 10+ years of scripts he’s collected.
  • Eduardo Pivaral shares a script he uses to output query results into an HTML table, making it easy to copy into an email.
  • Raul Gonzalez shows us a versatile script for searching database tables and returning information on attributes such as column name, size, key definitions, and more.
  • Matthew McGiffen wanted to find the most expensive queries on an instance using Query Store instead of the traditional DMVs, so he wrote a script to do just that.
  • Daniel Hutmacher shares his beefed up version of sp_help.  Includes ASCII art dependency graphs and database search.
  • Christian Gräfe provides a function he wrote for padding the left-side of a value with zeros.
  • Adrian Buckman  shares his SQLUndercover Inspector HTML reporting tool, as well as scripts for helping to alter AG groups, checking for running jobs, and auditing failed logins.
  • Louis Davidson shares his technique for using relative positioning in date tables to make querying custom periods (eg. your company’s fiscal month) easier.
  • Lance England shares a PowerShell script to automate generating upsert merge statements for his ETLs.

Code You Would Hate To Live Without (T-SQL Tuesday #104 Invitation)

Published on: 2018-07-03

The recent news about Microsoft acquiring GitHub has me thinking about how amazing it is for us to be part of today’s online code community.

Before modern online programming communities, finding good code samples or sharing your own code was challenging.  Forums and email lists (if searchable) were good, but beyond that you had to rely on books, coworkers, and maybe a local meetup of like-minded individuals to help you work through your programming problems.

Check out this month’s T-SQL Tuesday invitation in visual form!

Today, accessing and using code from the internet is second nature – I almost always first look online to see if a good solution already exists.  At the very least, searching blogs, GitHub, and StackOverflow for existing code is a great way to generate ideas.

For this month’s T-SQL Tuesday, I want you to write about code you’ve written that you would hate to live without.

Maybe you built a maintenance script to free up disk space, wrote a query to gather system stats for monitoring, or coded some PowerShell to clean up string data.  Your work doesn’t need to be completely original either – maybe you’ve improved the code in some open source project to better solve the problem for your particular situation.

There’s probably someone out there in the world who is experiencing the same problem that you have already solved; let’s make their life a little easier by sharing.

And don’t worry if your code isn’t perfect – just explain how your solution works and if you are aware of any caveats.  If it’s not an exact solution for someone else’s problem, at the very least it may help them generate some ideas.

Finally, here’s a reminder of the official rules for T-SQL Tuesday:

  1. Publish your contribution on Tuesday, July 10, 2018. Let’s use the “it’s Tuesday somewhere” rule.
  2. Include the T-SQL Tuesday Logo and have it link to this post.
  3. Please comment below with a link to your post (trackbacks/pingbacks should work too but…comments ensure I don’t miss your post)
  4. Tweet about your post using #tsql2sday.
  5. If you’d like to host in the future, contact Adam Machanic.

Contributing to Community

Published on: 2018-05-08

This post is a response to this month’s T-SQL Tuesday #102 prompt by Riley Major. T-SQL Tuesday is a way for SQL Server users to share ideas about different database and professional topics every month.

The prompt I’ve chosen to write about this month is how and why I got started contributing to the SQL Server community.


About a year ago, I was determined to improve my presentation skills.  I knew that in order to do that I needed to get more practice speaking.

I already was at my max for presenting at local user groups, conferences, etc… because at some point it becomes too cost and time prohibitive to travel to more events.  As an alternative, I decided that if I couldn’t get more practice by speaking in person, I could at least film myself presenting.

And I figured if I’m already filming myself presenting, I might as well put a little extra polish on it and make the content available for others to watch.

And that is how I started filming weekly videos about SQL Server.

SQL Server Videos

There are already plenty of great SQL Server presentations on YouTube, spanning a plethora of topics from a variety of experts who know way more about SQL Server than me.

Whenever I want to learn about a SQL Server topic, I search for something like “SQL Server backups” or “SQL Server columnstore indexes” on YouTube.  There are plenty of great recorded presentations, virtual chapter screencasts, Q&As, and other tutorials for learning almost any topic you can imagine.

However, sometimes I’m not in the mood to watch in-depth hour long presentations.  Sometimes I want to watch a short, informative, regularly scheduled entertaining SQL videos – and this is where I saw a gap in programming.

So what better way to get what you want than by scratching your own itch.  I figured if I want to watch that type of SQL Server video, then I’m sure other people out there want to watch those same kinds of short SQL videos too.

Bert, the Director

When I was a kid, I wanted to be a movie maker.  In particular, I was entranced by special effects, so I made movies with friends that involved plenty of lightsabers, explosions, and green screen effects all throughout middle school and high school.

So while making SQL videos wasn’t going to be totally new territory, I sure was unprepared for all of the initial work involved.

For the first three months, I was spending 15-20 hours per week writing, creating demos, shooting, editing, publishing, and marketing my videos.  Over time I’ve cut this process down to 8-10 hours a week, a more manageable amount of work that I can mostly get done on weekend mornings before the rest of the house wakes up.

Results

Making videos about SQL Server has been an amazing experience.  Not only do I personally feel fulfilled creating something week after week that improves my own skills, but it’s rewarding to receive positive feedback via comments, messages, and emails that I’m also helping others become better SQL developers.

Contributing has also made me appreciate how amazing the #sqlfamily community truly is.  Everyone I talk to is wonderful and supportive, and everyone I meet wants to see one another succeed.

Your Turn

If you aren’t already, I hope you consider contributing to the community .  Whether it be via blog posts, code contributions, presenting, tweeting, or making videos, giving back to the SQL Server community will grow your own skills and allow you to meet some really great people.

It can be scary putting yourself out there publicly, but don’t let that stop you.  If you give it your best then the SQL Server community won’t let you down.
