What did you do?
./v -g -o vdbg cmd/v && ./vdbg repro.v

import db.sqlite

struct Test {
	id int @[primary; serial]
}

fn main() {
	db := sqlite.connect(':memory:')!

	x := Test{}
	x_id := sql db {
		insert x into Test
	} or {
		panic(err)
	}
	println(x_id)
}

If you don't have the x_id := part, it gets marked as used correctly.

What did you expect to see?

No warnings
