Hello. I am trying to merge two datasets. What I would like to do is full join per subject ID even though date_time from dataset 1 doesn't exisit in dataset 2; 

 

First dataset: 

SubjectIDdate_timevalue1
1231/1/2010 9:5352.1
1231/2/2010 10:3121.2
1231/3/2010 9:3332.3
4562/1/2010 9:5342.2
4562/2/2010 10:31123.4
4562/3/2010 9:3347.2
4562/4/2010 14:2344.4

 

second dataset:

SubjectIDdate_timevalue1value2
1231/1/2010 9:5352.110.2
1231/2/2010 10:3121.242.1
4562/1/2010 9:5342.244.8
4562/4/2010 14:2344.432.2

 

want:

SubjectIDdate_timevalue1value2
1231/1/2010 9:5352.110.2
1231/2/2010 10:3121.242.1
1231/3/2010 9:3332.3 
4562/1/2010 9:5342.244.8
4562/2/2010 10:31123.4 
4562/3/2010 9:3347.2 
4562/4/2010 14:2344.432.2

 

Here's my code so far:

 


proc sql;
select t1.subjectid, t1.date_time, t1.value1, t2.value2
from dataset1 t1
left outer join dataset2 t2
where t2.value2 is null 

 

any help would be greatly appreciated
