说明：数据中一个字段，类型为BINARY，存放星期一到星期日中间的某一天或者某几天的组合比如:20(10100)，表示周二和周四，1表示周六，64(1000000)表示周日；

读取以及处理示例：

        //读取字节        byte[] daysOfWeekArr = new byte[1];InputStream is = dbResult.getBinaryStream("Days_Of_Week");is.read(daysOfWeekArr);is.close();//二进制 判断 星期       if((daysOfWeekArr[0] & 2) != 0) {       schedule.getDaysOfWeek()[0] = BnbScheduleDef.BBACTION_MON;        }        if((daysOfWeekArr[0] & 4) != 0) {        schedule.getDaysOfWeek()[1] = BnbScheduleDef.BBACTION_TUE;        }        if((daysOfWeekArr[0] & 8) != 0) {        schedule.getDaysOfWeek()[2] = BnbScheduleDef.BBACTION_WED;        }        if((daysOfWeekArr[0] & 16) != 0) {        schedule.getDaysOfWeek()[3] = BnbScheduleDef.BBACTION_THU;        }        if((daysOfWeekArr[0] & 32) != 0) {        schedule.getDaysOfWeek()[4] = BnbScheduleDef.BBACTION_FRI;        }        if((daysOfWeekArr[0] & 64) != 0) {        schedule.getDaysOfWeek()[5] = BnbScheduleDef.BBACTION_SAT;        }        if((daysOfWeekArr[0] & 1) != 0) {        schedule.getDaysOfWeek()[6] = BnbScheduleDef.BBACTION_SUN;        }
