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

Are the inputs always of fixed dimensions eg. 1 by 7?
