ARRAY_CONCAT (|| operator)
Applies to ✅ Open Source Edition ✅ Express Edition ✅ Professional Edition ✅ Enterprise Edition
The ARRAY_CONCAT (or ARRAY_CAT) function allows for concatenating arrays (see also ARRAY_APPEND and ARRAY_PREPEND for API to concatenate single values with arrays):
SELECT ARRAY[1, 2] || ARRAY[3, 4]
create.select(arrayConcat(array(1, 2), array(3, 4))).fetch();
The result would look like this:
+--------------+ | array_concat | +--------------+ | [1, 2, 3, 4] | +--------------+
See CONCAT for a text version of this function.
