Counting number of unique values in a column

Hi,

 

Very basic question.

 

I'm looking at data from over 6000 patients. In a given column that contains various WHO diagnosis codes I want to enumerate/sum how many patients have diagnosis X, how many have diagnosis Y, how many have diagnosis Z etc. How do I do that?

 

Other columns will contain other information, but the principele should still be applicable.

 

Kind regards,

 

Peter
