sql and week starting ending numbers (dates)

Hello all, I am creating a finance manager in php and mysql for my own accounting purposes (and to broaden my skills in php and sql) and I have a couple of pages where I view statistics on how much I spend, etc, and what patterns are formed from my spending. I have made a couple of pages with different statistics, and on one specific page, I show how much I spend total each week... The following query does that, but I want to display the start date and end date of the week. $sql = "SELECT YEARWEEK(purchaseDate,1) AS week, CONCAT_WS(' ',MONTHNAME(purchaseDate), YEAR(purchaseDate),'- Wk', WEEK(purchaseDate,1)) AS month, SUM(itemPrice) AS total FROM tblCashflow WHERE userID_FK = ${user['userID']} AND Type = 'Expenditure' GROUP BY week"; OK, so the sql works, and the output on the page looks like something below... February 2002 - Wk 5 $49.70 February 2002 - Wk 7 $12.95 February 2002 - Wk 8 $53.29 February 2002 - Wk 9 $275.99 March 2002 - Wk 10 $78.95 March 2002 - Wk 11 $171.15 March 2002 - Wk 12 $82.85 March 2002 - Wk 13 $20.50 April 2002 - Wk 14 $55.15 April 2002 - Wk 15 $30.55 April 2002 - Wk 16 $104.20 April 2002 - Wk 17 $461.95 May 2002 - Wk 18 $152.75 May 2002 - Wk 19 $219.80 May 2002 - Wk 20 $133.55 May 2002 - Wk 21 $98.65 Now thats all well and good, but I want to make it display something like the following: February 1 - 7 2002 $49.70 February 8 - 15 2002 $12.95 February 16 - 23 2002 $53.29 etc etc etc Does anyone have any idea on how this could be achieved? I looked at the mySQL time and Date functions, but I couldn't find out how to do it with that, and I think doing the work in PHP might be the answer.... Also, currently the SQL statement only shows the weeks where I have spent money, so if I don't spend anything in that week, it won't show up at all, although I would like it to say "January 12 - 19 2002 $0" or something like that. Below is my table schema for the above query Adam CREATE TABLE tblCashflow ( ID bigint(20) NOT NULL auto_increment, purchaseDate date default NULL, categoryID_FK tinyint(4) default NULL, itemName text, itemPrice float default '0', isEssential tinyint(4) default '0', paymentTypeID_FK tinyint(4) default '1', receiverID_FK tinyint(4) default NULL, itemDesc text, Type text, userID_FK int(11) default NULL, PRIMARY KEY (ID) );
