Hi,

How to have an output using eval for a unique values in a “name” calumn?

Data;  
{:name=\>“maria”, :name=\>“lorie”, :name=\>“maria”, :name=\>“smith”,  
:name=\>“maria”}

{:name=\>“maria”, :name=\>“den”, :name=\>“maria”, :name=\>“smith”,  
:name=\>“ole”}

Output would be;  
maria  
lorie  
smith  
den  
ole

Thanks in Advance!

Hi,

Could you please elaborate on your question, also if your data is a  
hash,  
how come you can have same keys repeated again?
