如何在MySQL中的json数据列中查找和替换？

Question

带有此json数据的测试列的Sql列Json。

{
   "nid": "262574",
   "title": "jhhdjg du fdgfjhdf ",
   "sub_data": {
      "1": {
         "nid": "262576",
         "title": "Lorem Ipsum is simply dummy text of the printing and typesetting",
         "sub_data": [
            {

               "url_alias": "#262576-1",
               "container_type": "text"
            },
            {
               "url_alias": "/diseererase/dfdf/dfdf-dfdf/sbfg us-wave-1/fggere emerging-",
            },
            {

               "url_alias": "#262576-6",
               "container_type": "text"
            },
         ],
         "url_alias": "/diseererase/dfdf/dfdf-dfdf/sbfg-us-wave-1/fggere emerging-therapies-dupixent us-wave-1 february 2019",
         "versionID": "1375544",

      }
   },
   "url_alias": "/ererer/dfdfdf/emedfd fdfpies/dupdfdf umab-us-wave-1",
   "versionID": "1375538",
   "container_type": "report",

},

如何获取其中带有空格的url_alias并在mysql查询中替换为-？

还有些人 也该如何处理？
