Does the Help Center cover all of the rules users are expected to know?

Before posting my question I did my due diligence and read the following Help Center pages:

1. What topics can I ask about here? and
2. What types of questions should I avoid asking?

However after posting my question, A one-liner to produce 1,2,3 in one Sqlite column, I was met with downvotes and my post closed. Pointing to the the meta post My question was closed as being off-topic. What are my options?

I feel like the Help Center doesn't adequately inform users on the rules for the site.

I think this might be better suited to StackOverflow. While the code is indeed complete and works as intended, Code Review is more about how to do things the right way instead of how to beat square pegs into round holes. :)

They would just tell me to use seq 3. That is not what I'm here for.

Well, that's internet for you. You can just ignore them and hope that someone is actually able to read and understand your question.

The main problem with this question is that it's too generic. We are not told anything about what you're actual code or actual context is. We want to give you the best possible answer which is why we require context with the code.

What's the point of this code? I feel like this is missing significant context. Without that context and motivation for why you're even using sqlite in the first place, we have no grounds to tell you anything other than "just use seq 3". This perfectly illustrates this close vote reason: "Missing Review Context: Code Review requires concrete code from a project, with enough code and / or context for reviewers to understand how that code is used. Pseudocode, stub code, hypothetical code, obfuscated code, and generic best practices are outside the scope of this site."
