Convert hash to struct

[Amita Ekbote]

I wanted to make a more generic way of doing this so that even if the
columns are modified or new ones are added it should be simple. Anyway
I will reconsider this sort of am implementation. Just out of
curiosity is there any other way of achieving this?

Thanks
Amita
