I'm not sure you want to actually include job_id here. I see it's used in the example, but I haven't tried this out. If I look at the rest resource it's definitely not including something for query about the job_id. I suspect it might work once but if you ran it again it would fail. I think if you remove it, it will consistently work, but I could be wrong.

[ccarpentiere]

Job ID is required. Agreed, you can't re-run without iterating on the job ID. Looks like maybe I could use https://registry.terraform.io/providers/hashicorp/random/latest/docs/resources/uuid to generate a unique ID? Let me give that a try.

Cool, that would be helpful. Thank you!

minor nit: the other samples have slightly different SQL, the majority do a LIMIT 100 so would be helpful to do the same here.
