Return all columns with distinct on multiple columns in SQL table

Question

I have 5 columns in sql table and I need all the 5 columns as out put but with distinct operation on three columns

Need to return all the columns with distinct operation

Answer 1

You can use a groupby for the three columns you want 'distinct'.

Answer 2

Can group by 3 but must use some type of aggregate function like min or max on the other two

select col1, col2, col3, max(col4), min(col5) 
from tbl 
group by col1, col2, col3
