How can I group by date time column without taking time into consideration

Question

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's an example that I used when I needed to count the number of records for a particular date without the time portion:

select count(convert(CHAR(10), dtcreatedate, 103) ),convert(char(10), dtcreatedate, 103)
FROM dbo.tbltobecounted
GROUP BY CONVERT(CHAR(10),dtcreatedate,103)
ORDER BY CONVERT(CHAR(10),dtcreatedate,103)
