JSON_INSERT function
Applies to ✅ Open Source Edition ✅ Express Edition ✅ Professional Edition ✅ Enterprise Edition
The MySQL style JSON_INSERT function is a function that adds but doesn't replace (JSON_REPLACE) a value in a JSON document, given a JSON path.
SELECT
JSON_INSERT('{"a":1}', '$.a', 2),
JSON_INSERT('{"a":1}', '$.b', 2)
create.select(
jsonInsert(val(json("{\"a\":1}")), "$.a", 2),
jsonInsert(val(json("{\"a\":1}")), "$.b", 2)).fetch();
The result would look like this:
+-------------+---------------+
| json_insert | json_insert |
+-------------+---------------+
| {"a":1} | {"a":1,"b":2} |
+-------------+---------------+

Oracle
json_transform('{"a":2}', INSERT '$.a' = 2 IGNORE ON EXISTING)
SQLServer
CASE
WHEN coalesce(
json_query('{"a":2}', '$.a'),
json_value('{"a":2}', '$.a')
) IS NOT NULL THEN '{"a":2}'
ELSE json_modify(
json_modify('{"a":2}', '$.a', ''),
