How to count number of records per day?

I have a table in a with the following structure:

CustID --- DateAdded ---

 396       2012-02-09 
 396       2012-02-09 
 396       2012-02-08 
 396       2012-02-07 
 396       2012-02-07
 396       2012-02-07 
 396       2012-02-06
 396       2012-02-06

I would like to know how I can count the number of records per day, for the last 7 days in SQL and then return this as an integer.

At present I have the following SQL query written:

SELECT * 
  FROM Responses
 WHERE DateAdded >= dateadd(day, datediff(day, 0, GetDate()) - 7, 0)

RETURN

However this only returns all entries for the past 7 days. How can I count the records per day for the last 7 days?

Solution 
  • select DateAdded, count(CustID)
from Responses
WHERE DateAdded >=dateadd(day,datediff(day,0,GetDate())- 7,0)
GROUP BY DateAdded
