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} | +-------------+---------------+
Dialect support
This example using jOOQ:
jsonInsert(val(json("{\"a\":2}")), "$.a", 2)
Translates to the following dialect specific expressions:
-- MARIADB, MYSQL, SQLITE json_insert('{"a":2}', '$.a', 2) -- ORACLE json_transform('{"a":2}', INSERT '$.a' = nvl(NULL, 2) IGNORE ON EXISTING) -- SQLSERVER CASE WHEN coalesce( json_query('{"a":2}', '$.a'), json_value('{"a":2}', '$.a') ) IS NOT NULL THEN '{"a":2}' ELSE json_modify( json_modify('{"a":2}', '$.a', ''), ('strict ' + '$.a'), 2 ) END -- ACCESS, ASE, AURORA_MYSQL, AURORA_POSTGRES, BIGQUERY, COCKROACHDB, DB2, DERBY, DUCKDB, EXASOL, FIREBIRD, H2, HANA, -- HSQLDB, INFORMIX, MEMSQL, POSTGRES, REDSHIFT, SNOWFLAKE, SQLDATAWAREHOUSE, SYBASE, TERADATA, TRINO, VERTICA, YUGABYTEDB /* UNSUPPORTED */
