    Unhappy DUplicate Value Insertion in database Problem

    So here i have a database called expiringLicences which is filled with expiring licences as the software starts
    My problem here is ,it is inserting the same expiring licences over and over again as the software starts and my expiringLicences table is filled with duplicate values

    + " select licenceno,licencedate,Balance,noofdaysforexpiry from importlicencedetails where noofdaysforexpiry<"+(90)+" AND expiringlicences.LicenceNo<>importlicencedetails.l icenceno";
