Coalesce 2 Arrays

[Alex Magnum <magnum11200@xxxxxxxxx>]

Hi,
I have two arrays which I need to combine based on the individual values;

i could do a coalesce for each field but was wondering if there is an easier way

array_a{a,   null,c,   d,null,f,null}  primary

array_b{null,2   ,null,4,5   ,6,null}  secondary

 

result {a,   2,   c,   d,5,   f,null)

Any advice would be appreciated
