Question

一个包含列的表包含跟随

的数据

[{"id":"1","value":"addy"},{"id":"2","value":"fname"},{"id":"3","value":"lname"},{"id":"4","value":"kfjsdkfj"},{"id":"5","value":"1985-12-02"},{"id":"6","value":"20"},{"id":"7","value":"20"},{"id":"8","value":"2"},{"id":"9","value":"20"},{"id":"10","value":"20"},{"id":"11","value":"20"},{"id":"12","value":"20"},{"id":"13","value":"1"},{"id":"14","value":"kljfk"},{"id":"15","value":"2"},{"id":"16","value":"1"},{"id":"17","value":"2"},{"id":"18","value":"3"},{"id":"19","value":""},{"id":"20","value":"1"}]

这只是一个示例数据，我有几千行像不同的值

我希望过滤此列，例如日期范围和数据范围

我试过

 `SELECT * 
  FROM  `my_table` 
  WHERE  `my_field` 
  REGEXP  '{"id":"15","value":"(1[0-9]|2000)"}'

`在查询条件下但是没有成功

什么正则表达式帮助我按范围找到值？

试试吧

SELECT id FROM table_name WHERE field_name REGEXP＆＃39;＆＃34; key_name＆＃34;：＆＃34;（[^＆＃34;] ）key_word（[^＆＃34;] ）＆＃34;＆＃39 ;;

mysql在一列中使用范围过滤多个json数据
