Count duplicate entries in single column (SQL)

FCervera

I'm trying to create a SQL query that outputs duplicate values in a sequence. There are other similar posts, but none that seem to work for my needs.

Here is what I've tried so far.

select created, count(*)
from users
group by created

... with the following results

2010-10-12 12:06:44 1
2014-02-24 20:36:50 1
2014-02-25 11:14:18 1
2014-02-25 14:13:44 1
2014-02-25 21:08:53 1
2014-02-25 22:22:17 1
2014-02-26 01:59:07 1
2014-02-26 12:08:59 1

But, I'm actually trying to get it into this format.

2010-10-12 1
2014-02-24 1
2014-02-25 4
2014-02-26 2

I need the count of each date, but haven't been able to get the right query. Thank you for your help.

Trim the time part in created column in Group by to get the count of each day.

To do this you can either use Cast or Date function

select cast(created as date), count(*)
from users
group by cast(created as date)
