I have a bunch of product orders and I\'m trying to group by the date and sum the quantity for that date. How can I group by the month/day/year without taking the time part

Answer 1

Here is the example works fine in oracle

select to_char(columnname, 'DD/MON/yyyy'), count(*) from table_name group by to_char(createddate, 'DD/MON/yyyy');
