Question

I am currently using the query below to collect a total of the ER_read table in between 2 dates. This works fine but I need to split these results into weekly segments e.g. the first week of october = 40 (i think). Is there a function in MsSQL or PHP to do this, and how would I use it?

  SELECT SUM(ER_read) as total
    FROM tblEread
   WHERE ER_ID='$sensor'
     AND MONTH(ER_date) >= '$firstMonth'
     AND MONTH(ER_date) <= '$lastMonth'
     AND YEAR(ER_date) = '$year'
GROUP BY ER_ID;

Thanks for any help

Following tagging from mySQL to MSSQL, see here:
