How to parse Json in MySQL level?

I've version MySQL version 5.6.26 in XAMPP

MySQL --version

MySQL Ver 14.14 Distrib 5.6.26, for Win32 (x86)

I created a table.

CREATE TABLE `message` (

`id` int(11) NOT NULL AUTO_INCREMENT,

`data` text,

PRIMARY KEY (`id`)

);

Inserted some rows

INSERT INTO message (id,data) VALUES(1,'{"from":"chris","title":"Awesome Article","body":"Lorem ipsum dolor sit amet, consectetur adipiscing elit."}');

INSERT INTO message (id,data) VALUES(2,'{"from":"loren","title":"Another Article","body":"Lorem ipsum dolor sit amet, consectetur adipiscing elit."}');

INSERT INTO message (id,data) VALUES(3,'{"from":"jason","title":"How to run a query","body":"Lorem ipsum dolor sit amet, consectetur adipiscing elit."}');

and I try to get Json values:

SELECT Json_get(data,'title') FROM message WHERE id=2;

And I get error:

SELECT json_get(data,'title') FROM message WHERE id=2;

ERROR 1305 (42000): FUNCTION mydatabasename.json_get does not exist

Has anybody ideas?

You can parse json data using common_schema, try following code it may help you :-

SELECT common_schema.extract_json_value(data,'title') FROM message WHERE id=2;
