您可以根据JSONB从左边的JSONB加入，这可能代表右侧的任何列？

Question

我的收集表将是这样的：

|id |title                    |jsonb_structure                                 |
|1  |Widescreen Horror Movies |{"genre":["horror"], "aspect_ratio":["2.39"]}   |
|2  |Widescreen digital Films |{"aspect_ratio":["2.39"], "format":["digital"]} |

收集1将返回锯，nosferatu和nope。集合2将返回nope。

添加具有数字格式的2.39宽高比的新电影将被分组到宽屏数字收藏室中

|6 |The Stand |horror |2.39 |Digital |

在现实中，电影表有9列，将来可能还有更多的内容，我想以这种方式过滤。是否可以用一个语句检索标题？这是最好的方法吗？

具有测试数据
