> "A picture of a schema"? What does this mean?
A hand-drawn picture of a database schema. Something like this:

> And by SQL do you mean DDL?
DDL is a subset of SQL, so the distinction is moot.
Huh, weird stuff!
Your linked image shows what appear to be tables, and the little arrows appear to represent entity-relationships between them. But I'm not sure how you'd get useful DDL out of it -- none of the columns have types, no indices, etc.!
Maybe an LLM could sketch out a DDL skeleton from a picture, which someone could use as a starting point?
LLMs can infer a lot of details from "common sense" (i.e. statistical association). As a human, I can figure out what each field's types should be, so your frontier LLM could, too: https://chatgpt.com/share/680e3a90-8660-8003-998f-91ad98e32f...
You and a LLM can guess at what the types might be, but those guesses are a suggestion that a human needs to evaluate, they're not something you can just pass thru as assumptive defaults. In your link, for example, I would definitely not want CategoryID to be an INT, or UnitPrice to be a DECIMAL, or etc.
