Hi,
I have a transactoin table with transactionid and contactid.
There can be same transactionid for multiple contacts.
I'm trying to figure out how to get the count of unique transactionid AND contactids, but im not sure how to use the 'distinct' function correctly to get it, so far i have:
proc sql;
select
count (distinct transactionid contactid) as unique
from transaction_table
;
quit ;
im getting a syntax error on the count statement.
thanks for your help.
I figured it out.
proc sql;
select
count (distinct transactionid || contactid) as unique
from transaction_table
;
quit ;
proc sql;
select
count (distinct transactionid ) as unique_trans,
count (distinct contactid) as unique_contact
from transaction_table
;
quit ;
I figured it out.
proc sql;
select
count (distinct transactionid || contactid) as unique
from transaction_table
;
quit ;
