Mysql can handle json. To handle the JSON field in Mysql, you can use the json_extract function, for example, "SELECT * FROM proxy WHERE json_extract (content," $. Method ") =" POST ";" statement.
Dealing with JSON fields in Mysql
To handle the json field, you can use the json_extract function:
Select * from (select json_extract (ext_value,'$.high') + 0 highx,batch_id from batch_ext_1 where ext_type=19) a where a.highx > 15000000000SELECT * FROM proxy WHERE json_extract (content, "$.method") = "POST"
