SQL Server - Orders By Client with 1 minute difference -

-

i have table 3 columns

clientid | orderid | createddate   1 | 1 | 2015-10-27 10:00:00   1 | 2 | 2015-10-27 10:00:30   2 | 3 | 2015-10-27 10:30:30   3 | 4 | 2015-10-27 10:35:00   3 | 5 | 2015-10-27 10:35:45   3 | 6 | 2015-10-27 12:30:00

i want count number of orders same client inserted (more or less) in same minute.

this way expected result be

clientid | count(orderid)   1 | 2   2 | 1   3 | 2   3 | 1

i've tried using inner join wasn't able it. suggestions?

try this:

create table #myorders (     clientid int,     orderid int,     createddate datetime )   insert #myorders values     (1,1,'2015-10-27 10:00:00'),     (1,2,'2015-10-27 10:00:30'),     (2,3,'2015-10-27 10:30:30'),     (3,4,'2015-10-27 10:35:00'),     (3,5,'2015-10-27 10:35:45'),     (3,6,'2015-10-27 12:30:00')  select  clientid, count(*) [count(orderid)] #myorders group clientid, dateadd(minute, datediff(minute, 0, createddate), 0)

this gives

clientid    count(orderid) --------    -------------- 1           2 2           1 3           2 3           1
