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.
