JSON_SET function
Applies to ✅ Open Source Edition ✅ Express Edition ✅ Professional Edition ✅ Enterprise Edition
The MySQL style JSON_SET function is a function that adds (like JSON_INSERT) or replaces (JSON_REPLACE) a value in a JSON document, given a JSON path.
SELECT
JSON_SET('{"a":1}', '$.a', 2),
JSON_SET('{"a":1}', '$.b', 2)
create.select(
jsonSet(val(json("{\"a\":1}")), "$.a", 2),
jsonSet(val(json("{\"a\":1}")), "$.b", 2)).fetch();
The result would look like this:
+----------+---------------+
| json_set | json_set |
+----------+---------------+
| {"a":2} | {"a":1,"b":2} |
+----------+---------------+
Dialect support
This example using jOOQ:
jsonSet(val(json("{\"a\":1}")), "$.a", 2)
Translates to the following dialect specific expressions:
-- MARIADB, MYSQL, SQLITE
json_set('{"a":1}', '$.a', 2)
-- ORACLE
json_transform('{"a":1}', SET '$.a' = 2)
-- SQLSERVER
json_modify(
json_modify('{"a":1}', '$.a', ''),
('strict ' + '$.a'),
2
)
