    Person.self,
    content: Person(id: nil, name: "Ada", age: 31),
    where: Person.Fields.name == "Ada"
)

// Update a specific record
let id = SurrealRecordID(table: "person", id: .string("ada"))
let record: Person? = try await client.update(
    recordID: id,
    content: Person(id: nil, name: "Ada", age: 31)
