column j format a20
with
   t (j) as (values
      (json('["a", "b"]')),            -- JSON array
      (json('{"a": "a", "b": "b"}')),  -- JSON object without id property
      (json('{"id": 42}')),            -- JSON object with numeric id property
      (json('{"id": "42"}'))           -- JSON object with string id property
   )
select j,
       j is json validate '
          {
             "type": "object",
             "properties": {
                "id": { "type": "number" }
             }
