OleDbConnection baglanti = new OleDbConnection(baglantiCumlesi);
            baglanti.Open();

            string sorgu = "SELECT P.ADISOYADI, UNVANI, T.DAHILI ,'<a href=mailto:'||EMAIL||'>'||EMAIL||'</a>' AS EMAIL"+
                           " FROM PERSONEL P"+
                           " LEFT JOIN TELELINK L ON L.INTERNAL = P.PERSONEL_NO"+
                           " AND L.SINTERNAL = 'PERS' AND L.VARSAYILAN = 'E'"+
                           " LEFT JOIN TELEFONL T ON T.TELEFON_NO = L.TELEFON_NO"+  
                           " WHERE WEB_AKTIF = 'E' AND PERSONEL_NO > 0 AND BLOKE = 'H'"+
                           " ORDER BY PERSONEL_KODU";
