Current Invitation

The current invitation (November 2022) is for T-SQL Tuesday #156. The next invitation should be released on December 6.

T-SQL Tuesday #156 – Production Code

Invitation from Tom Zika.

I’m a learner by example, so when I started programming (not so long ago), I tried to find existing solutions on various Q&A sites or blogs, as one might.

After a while, I noticed one sentence repeating often enough that it stuck with me:

“This is not a production-grade code”.

So here’s my invitation: “Which quality makes code production grade?”

You might think: “Production code is code that runs in production, duh.”

But let’s help out the newbies who look for a bit of concrete guidance.
Please be as specific as possible with your examples and include your reasoning.

I’m not limiting the scope to just the SQL; it can be anything.
