JSON_REMOVE

Syntax

JSON_REMOVE(json_doc, path[, path] ...)

Description

Removes data from a JSON document returning the result, or NULL if any of the arguments are null. If the element does not exist in the document, no changes are made.

The function returns NULL and throws a warning if the JSON document is invalid, the path is invalid, contains a range, or contains a * or ** wildcard.

Path arguments are evaluated from left to right, with the result from the earlier evaluation being used as the value for the next.

SELECT JSON_REMOVE('{"A": 1, "B": 2, "C": {"D": 3}}', '$.C');
