Select Distinct

Can I run Select distinct on one fieldname only while I'm selecting more than one fielname, like

Select Distinct col1, col2, col3 from table

I need distinct on col1 only and not on the other 2 columns, is it possible.

Thanks

Distinct means DISTINCT across all selected columns. If you want distinct on one column, then you need to know how to handle the duplicates on the other columns...you have to use an aggregate function like

select col1, MAX(col2), MIN(col3), AVG(Col4) -- any you prefer
from table
group by col1
