Question!

Note: In the MySql database, "dob" is varchar and in this format: mm/dd/yyyy

Date of birth, Cvrg Effective Date, & Cvrg Expiration Date need to be changed from mm/dd/yyyy to yyyymmdd when it arrives in Excel. Please see the code below:

    <?php 
    if($qry == "ok"){
     // get db connection
     include("connection string goes here");

     $select = "SELECT 'A' AS 'Transaction Type', policyno AS 'UHCSR Policy No', school                 AS 'Campus Location Description', Code AS 'Campus Location Number', '' AS 'Date Received by         UHCSR', '' AS 'Date Stamped By School', '' AS 'Social Security Number', SSN AS 'StudentID Number', 
      lname AS 'LastName', fname AS 'FirstName', mi AS 'Middle Initial', dob AS 'Date of Birth', gender AS 'Gender',
