JSON functions were added in MariaDB 10.2.3.

Syntax

JSON_INSERT(json_doc, path, val[, path, val] ...)

Description

Inserts data into a JSON document, returning the resulting document or NULL if any argument is null.

An error will occur if the JSON document is not invalid, or if any of the paths are invalid or contain a * or ** wildcard.

JSON_INSERT can only insert data while JSON_REPLACE can only update. JSON_SET can update or insert data.

Examples

SET @json = '{ "A": 0, "B": [1, 2]}';

SELECT JSON_INSERT(@json, '$.C', '[3, 4]');
+--------------------------------------+
| JSON_INSERT(@json, '$.C', '[3, 4]')  |
+--------------------------------------+
| { "A": 0, "B": [1, 2], "C":"[3, 4]"} |
+--------------------------------------+
