Hi,
For example, if you are using email addresses, they will surely be unique. But it is better to use a separate field as your primary key (eg. bigint auto_increment values). Just because it is unique, doesn't mean you should use it as primary key.

I can only guess that you are using an ARRAY and you have problems dealing with two dimensional arrays.
If that is the case then you may read a Tutorial on Multidimensiona l or arrays of arrays in JavaLeave a comment:
