JSON_REMOVE function

Applies to ✅ Open Source Edition   ✅ Express Edition   ✅ Professional Edition   ✅ Enterprise Edition

The MySQL style JSON_REMOVE function is a function that removes a value from a JSON document, given a JSON path.

SELECT
  JSON_REMOVE('{"a":1}', '$.a'),
  JSON_REMOVE('{"a":1}', '$.b')
create.select(
           jsonRemove(val(json("{\"a\":1}")), "$.a"),
           jsonRemove(val(json("{\"a\":1}")), "$.b")).fetch();

The result would look like this:

+-------------+-------------+
| json_remove | json_remove |
+-------------+-------------+
| {}          | {"a":1}     |
+-------------+-------------+
