In CB 4.6.0 and above

SELECT ARRAY_SYMDIFF([1, 2], [1, 2, 4]) ;
ARRAY_SYMDIFF – includes value when it appears only once.
ARRAY_SYMDIFFN – includes value when it appears odd number of times.

In Pre CB 4.6.0

SELECT ARRAY v FOR v IN ARRAY_DISTINCT(ARRAY_CONCAT( [ 1,2], [ 1,2,4])) WHEN v NOT IN ARRAY_INTERSECT([ 1,2], [ 1,2,4]) END;
