I think rather than just throwing this type of amazing ability out entirely due to potential malicious users, you can consider things like:

- using for internal tools with relatively small userbases such as employees in your department.

- using it with GPT-4 instead of 3.5 which can do a much better job of detecting malicious use.

- make a read-only copy of just the data that you want to expose.

- use a similar strategy but with something like PostgreSQL that has row-level-security.

Assume the end-user can write arbitrary SQL and LLM is just an interface for that.

Creating a read-only Postgres user with limited access might be a good workaround.

Not sure about avoiding infinite loops, CPU loads, etc. Curious to get an expert’s input on this.

What is the complaint here exactly? That LLMs aren't enforcing database access best practices for you? That's not their job, that's your job. LLMs generate text. You do the rest. Give the LLM a user with the correct access control rules. Add a reasonable timeout to your warehouse/database. Enforce rate limiting like you would with any other endpoint.

There is nothing malicious about Alter Table or Drop Table commands. These all have valid use-cases and is not something an LLM needs to guard against. If a bad-actor can issue these commands against your DB, you are already toast!

Don't overlook the damage potential of a fresh-faced college-hire on-call at 2am with dba access to prod

This is cracking me up. Whatever's needed to implement this in the real world, I can't imagine that it will involve securing the app with the same flaky system that's responsible for the vulnerabilities in the first place.

No complaint. It's more of a warning about how the main players (OpenAI, LangChain) share notebooks and cookbooks that illustrate how to make the LLMs "query" the databases. At the very least one would expect some language telling people to not do that in production. And it's not unique to SQL, this is just an extreme example.

Maybe "complaint" was the wrong word but I disagree with the conclusion that LLMs are "not for trustworthy production systems" for the reasons I stated.

Full disclosure, I wrote a blog post called "Text to SQL in Production." Maybe I should add a follow-up covering our guardrails. I agree that they are necessary.

In professional communication, is it necessary to repeat the obvious all the time? Does an article in a medical journal or a law journal need to explicitly remind its readers of 101 level stuff? If an unqualified person reads the article, misinterprets it because they don’t understand the basics of the discipline, and causes some harm as a result-how is that the responsibility of the authors of the article? Why should software engineering be any different?
