help with merge

[deleted_user]

Hi all. I merged two datasets with 2 different date variables. However some dates are the same for both variables (ex. date=12/1/07 date2=12/1/07). My question is:
Is there a way to remove the dublicate variable (and somehow keep the 1st one)?
For ex., can I say:

data all;
merge one two;
by name;
if date=date2 then remove date2;
run;

Any help would be appreciated. Thanks.

you could try recoding so that if data= date2 then date2=. then you could remove the missing, that may work
