SQLite 3.40 又把 right join 搞坏了，调试了老半天才发现是sqlite的问题（mac自带的sqlite是3.39.5，没有bug）
select a.key, b.value from json_each('{"a": 1, "b": 2}') a right join json_each('["a", "c"]') b on a.key = b.value
select a.key, b.value from json_each('{"a": 1, "b": 2}') a right join json_each('["a", "c"]') b on a.key = b.value
