So I am super new to proc sql.

My question is, can I have names of people populate in one column if they fit the condition, separated by a comma?

Like if there is a data set where people on a certain day at a certain time eat a piece of red candy, all the names of those people who fit that populate in one column separated by a comma? But still keep the other stuff like date and time distinct?

I hope I’m asking this correctly

I don't think it's doable (easily) in SQL, but it's easy in a data step:

data have;
input time name $;
datalines;
1 Alfred
1 Charles
2 Susy
2 John
3 James
;

data want;
set have;
by time;
retain all_names;
length all_names $100;
if first.time
then all_names = name;
else all_names = catx(",",all_names,name);
if last.time;
drop name;
run;
