JSON_REPLACE
Applies to ✅ Open Source Edition ✅ Express Edition ✅ Professional Edition ✅ Enterprise Edition
The MySQL style JSON_REPLACE function is a function that does not add add (like JSON_INSERT) but replaces a value in a JSON document, given a JSON path.
SELECT
JSON_REPLACE('{"a":1}', '$.a', 2),
JSON_REPLACE('{"a":1}', '$.b', 2)
create.select(
jsonReplace(val(json("{\"a\":1}")), "$.a", 2),
jsonReplace(val(json("{\"a\":1}")), "$.b", 2)).fetch();
The result would look like this:
+--------------+--------------+
| json_replace | json_replace |
+--------------+--------------+
| {"a":2} | {"a":1} |
+--------------+--------------+
Dialect support
This example using jOOQ:
jsonReplace(val(json("{\"a\":1}")), "$.a", 2)
Translates to the following dialect specific expressions:
MariaDB, MySQL, SQLite
json_replace('{"a":1}', '$.a', 2)
Oracle
json_transform('{"a":1}', REPLACE '$.a' = 2)
SQLServer
CASE
WHEN coalesce(
json_query('{"a":1}', '$.a'),
json_value('{"a":1}', '$.a')
) IS NULL THEN '{"a":1}'
ELSE json_modify(
json_modify('{"a":1}', '$.a', ''),
('strict ' + '$.a'),
2
)
