Hi Everybody,
I am a bit confused about distinct() function.
I wrote a simple query like this:
select subjectid, markerid, allele1id, allele2id
from tsakai.mygenotype2
where subjectid in (53684, 53688, 53699, 53700, 53704, 53705, 53713, 53714,
53716, 53724)
and
markerid in

Your confusion is in thinking that DISTINCT is a function. It is not;
it's just a keyword that modifies SELECT. Write
select distinct subjectid, markerid, allele1id, allele2id
