ARRAY_PREPEND (|| operator)

Applies to ✅ Open Source Edition   ✅ Express Edition   ✅ Professional Edition   ✅ Enterprise Edition

The ARRAY_PREPEND function allows for concatenating an element to the beginning of an array (see also ARRAY_APPEND and ARRAY_CONCAT):

SELECT 1 || ARRAY[2, 3]
create.select(arrayPrepend(1, array(2, 3))).fetch();

The result would look like this:

| array_prepend |
| [1, 2, 3]     |
