hi guys,
i got range of values in a daily date format and the are of datatype smalldatetime but, the values are daily and i want to find average of those values based on month.
NOTE: the value may not necessary be up to 30 or 31 days
e.g average of values from january 1, 2000 to december 29, 2006 based on month i.e one value for each distinct month

select dateadd(month, datediff(month, 0, yourdatetimecolumn), 0), avg(anothercolumnnamehere)
from yourtablenamehere
where yourdatetimecolumn >= '20000101' and yourdatetimecolumn < '20070101'
group by dateadd(month, datediff(month, 0, yourdatetimecolumn), 0)
