I\'m running a really simple query, however for some of the results the value in one field is null. How can I set that value to \"a string\" if its value is null?

    Check the COALESCE function

    SELECT RegName,RegEmail,RegPhone,RegOrg,RegCountry,DateReg,COALESCE(Website, 'no website') AS WebSite FROM RegTakePart WHERE Reject IS NULL
