MySQL-在JSON密钥对值中选择数据

Question

I'm trying to construct a MySQL query that would do the following:

Sample Data:

---------------------------------------------
|                  colm                     |
---------------------------------------------
|{"level":10, "something": "blah", etc}     |
---------------------------------------------
|{"level":3, "something": "blah", etc}     |
---------------------------------------------
|{"level":7, "something": "blah", etc}     |
---------------------------------------------
|{"level":21, "something": "blah", etc}     |

I need to SELECT rows where colm LIKE "%?%" with the ? being level is less than or equal to ( <= ) some value. For example, SELECT ing all rows where colm has the JSON string's level key-pair value <= 8 , getting the middle two rows.

How can I do this? I'm thinking something with JSON functions instead of using LIKE and % wildcards, but I'm not sure exactly what I need to do.

尝试这个：

SELECT * FROM <your-table> WHERE colm->"$.level" <= 8
