count question

Hi

I am trying to do a count of the total number of help desk calls for the last 30 days grouped within the last 8 days.

So my calculation would need to go based on the following

08/03/2012 -  "Count all the calls within the last 30 days from this date"
09/03/2012 -  "Count all the calls within the last 30 days from this date"
10/03/2012 -  "Count all the calls within the last 30 days from this date"
etc

My calls are logged by in unixtime and I can count the calls by their ID.
I am running mysql 4.0.16
Thanks

try:

select count(ID) from table where column_name between unix_timestamp('2012-03-8') and unix_timestamp(date_add('2012-03-08'), interval 30 day);

I was thinking more a long the lines of this command that I found
Source: http://www.joellipman.com/articles/sql/mysql/457-sql-queries-for-statistics.html

SUM(IF((HOUR(a.DateTimeStamp) BETWEEN 8 AND 18), 1, 0)) 'Worktime',

I was thinking of modifying so that it is between the logdate and the past 30 days. However I am not sure how to modify it so that it does this.

what exactly is the datatype of DateTimeStamp?  Is it Datetime or integer (for timestamp from unix epoch) ?

If it's datetime it can be something like:

sum(if(a.DateTimeStamp between '2012-03-08' and '2012-04-08', 1, 0))

I however do not really recommend it, as it likely won't make use of indexes on DateTimeStamp, if any.
