> Ex: Let's say I have records in a CSV file with the following schema
> {noformat}
> user_name, friend_list_separated_by_a_delimiter,other_fields
> ali,sam;adi;tom,45,...
> {noformat}
> I want to run a query which returns the friend list files as a repeated value.
> {noformat}
> select user_name, split(friend_list, ';') friends from userdata;
> {noformat}
> This should return the records in the following format
> {noformat}
> ---------------------------------
> | user_name | friends |
> ---------------------------------
> | ali | [sam, adi, tom] |
