JSON_ARRAY_INSERT

MariaDB starting with 10.2.3

JSON functions were added in MariaDB 10.2.3.

Syntax

JSON_ARRAY_INSERT(json_doc, path, value[, path, value] ...)

Description

Inserts a value into a JSON document, returning the modified document, or NULL if any of the arguments are NULL.

Evaluation is performed from left to right, with the resulting document from the previous pair becoming the new value against which the next pair is evaluated.

If the json_doc is not a valid JSON document, or if any of the paths are not valid, or contain a * or ** wildcard, an error is returned.

Examples

SET @json = '[1, 2, [3, 4]]';

SELECT JSON_ARRAY_INSERT(@json, '$[0]', 5);

+-------------------------------------+

SELECT JSON_ARRAY_INSERT(@json, '$[1]', 6);

| JSON_ARRAY_INSERT(@json, '$[1]', 6) |
+-------------------------------------+
| [1, 6, 2, [3, 4]]                   |
