需求

下单时间为21：00-23:59，并且收货时间为第二天的订单，将这些订单的收货时间改为第三天；

#!/bin/bash
###time：2016-04-26
###This script is change "specify_receive_time"
###作用：修改下单时间为21:00:00-23:59:59并且收货时间为第二天的订单，将收货时间改为第三天

TIME="`date +%F`"
NEXT_DAY="`date -d next-day +%F`"

MYSQL_DB="miracle"
MYSQL_CMD="/server/mysql5.5.39/bin/mysql"
MYSQL_USER="chtime"
MYSQL_PWD="密码"
###SELECT_MY="use miracle;"
###根据下单时间段：21:00:00-23:59:59(前一天),查询出收货时间
###SELECT_RETIME="SELECT specify_receive_time,order_sn FROM orders WHERE create_time>('"$LAST_DAY" 21:00:00') and create_time<('"$LAST_DAY" 23:59:59') and specify_receive_time>('"$TIME" 00:00:00') and specify_receive_time<('"$TIME" 23:59:59');"

ORDER_DIR="/data/order"
###ORDER_FILE="$ORDER_DIR/change_receive_time-`date +%F`.txt"
ORDER_FILE="$ORDER_DIR/change_receive_time-"$TIME".txt"
###生成log file
