JSON_ARRAY
Applies to ✅ Open Source Edition ✅ Express Edition ✅ Professional Edition ✅ Enterprise Edition
The JSON_ARRAY function is used to produce simple JSON arrays from scalar values, without aggregation(see also JSON_ARRAYAGG).
SELECT json_array(author.first_name, author.last_name) FROM author
create.select(jsonArray(AUTHOR.FIRST_NAME, AUTHOR.LAST_NAME))
.from(AUTHOR)
.fetch();
The result would look like this:
+----------------------+ | json_array | +----------------------+ | ["Paulo", "Coelho"] | | ["George", "Orwell"] | +----------------------+
