Hey! 

This is my code up to now:

 

proc freq data=123;
table issr_id;
where def=1;
run;

 

I want to know the total number of issr_id with the condition def=1.

But the Problem is, there are some issr_id with have more then one def=1.

 

How can I get the total number of issr_id with def=1, without issr_id with the same number are counted muliple times? 

 

 

Hope you get my question.

Thanks!

Not sure what you actually will count the frequency on.
What does uniquely identifies row in the input table?

It sounds like you're trying to get a frequency of unique issr_ids. Am I correct in assuming this? If so, before you do the proc freq, you could use PROC SQL and select distinct issr_ids, or a datastep and use by group processing to filter out issr_ids that are identical. Hope this helps.

It sounds like you are looking for just a single number as the output.  If so, this might do it:

 

proc sql;

select count(distinct(issr_id)) from have where def=1;

quit;

Then pick up the first obs wthin each group firstly.

 

proc sort data=123 out=_123 nodupkey;
 by def;
run;

proc freq data=_123;
table issr_id;
where def=1;
run;
