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} |
+-------------+-------------+
