MySQL Table:
User | PhoneNumber
--------------------------------
raman    1234
bhuvan  2345
atul       5678

Using single Collection column and map collection :

Phone Number
---------------------------
Map <raman,1234>
<bhuvan,2345>
<atul,5678>

Want to transform data in this way, i.e. key is mapped from value of "user" column in the map.

Any help will be appreciated.
