一个对字符串处理的SQL

某表中有一个json格式的字段 如props里有以下字符

现在要查出第56个属性的值

即有如何 SQL：

select passportId,level, cast(substring(props,position(',"56":' in props)+6,position(',"57":' in props)-position(',"56":' in props)-6) as signed integer) as num,cast(substring(props,position(',"56":' in props)+6,position(',"57":' in props)-position(',"56":' in props)-6) as signed integer)/1200 h_count from t_character_info where cast(substring(props,position(',"56":' in props)+6,position(',"57":' in props)-position(',"56":' in props)-6) as signed integer) >0;


如果在shell中分布试查出各个数据库的内容 并把内容邮件形式发出:
即把以上sql 存入到sql文件里

程序如下:
#! /bin/sh

last_date=$(date -d last-day +%Y_%m_%d);
cat /dev/null > $last_date.data
for s_ip in $(awk -F= '{print $0}' /root/action_shell/kr_ip.txt);
do
echo ===============================start to do task===================================================;
s=$(echo $s_ip|awk -F= '{print $1}');
ip=$(echo $s_ip|awk -F= '{print $2}');

echo '====================='$s'.cqkr.huayugame.com==============================================' >>/root/action_shell/$last_date.data
out1=$(mysql -h$ip -uxxx -pxxx -Dgen -e 'source query_hounter.sql' >> /root/action_shell/$last_date.data);

echo $out1;
sleep 10
echo ===============================send mail successfully===================================================;
done


/bin/mail -s 'from games.asia team tech '_$last_date mingming.wang@renren-inc.com games.asia< /root/action_shell/$last_date.data


运行效果如下:
