Question

I have a table with two column as :

serial_number
1
2
3

dateOfAppoinement
2011-06-30 00:39:04.130
2011-06-30 00:40:01.130
2011-06-30 00:49:04.130

I want to get the highest serial_number of a day. I have to avoid the time part. I’m just using the date part.

Can anyone tell me how can I do this?

Answer 1

I updated my answer to use Convert like snkmchnb suggested. However in SQL Server 2008 there is a DATE datatype that is just the date portion of the year so you don’t have to specify the 120 code. I tested this and it works perfectly and the SQL is pretty straight forward.

SELECT
    MAX(serial_number),
    CONVERT(DATE, dateOfAppointment) as [Day]
FROM
    #TempSerialsByDate
GROUP BY
    CONVERT(DATE, dateOfAppointment)
