i have code :

 

data test;
input name $ age;
datalines;
a 1
a 2
a 3
A 1
a 4
A 3
A 2
;
run;
proc sort data=test nodupkey ;
by name; run;
proc print; run;

 

output is : A 1

                a  1

desire output is : a 1 (only)

 

is there any possibility to ignore case and select only first unique record.(without any kind of manipulation in data and using only proc sort)

 

Thanks in advance

I don't think what you are attempting is possible with Proc Sort. It may be possible with proc sql however as you can upcase as needed:

 

You will either have to take a pass through a data step to UPCASE the variable(s) or add upcased variables.

 

Proc sql may give a similar result but does not have an actual concept of "first" so requires more code and likely data manipulation to maintain order.
