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: =====================s1.cqkr.huayugame.com=============================== passportId level num h_count 102833976 78 2400 2.0000 102835789 84 4800 4.0000 102837173 72 12000 10.0000 102837399 72 51600 43.0000 102837452 74 3600 3.0000 102839736 56 48000 40.0000 102775934 60 50400 42.0000 =====================s2.cqkr.huayugame.com================================== passportId level num h_count 102928945 76 2400 2.0000 102966633 63 72000 60.0000 102968267 64 12000 10.0000 102923416 67 1200 1.0000 102970589 57 48000 40.0000 102971607 68 28800 24.0000 102885000 69 12000 10.0000 102975125 64 24000 20.0000 102915079 69 10800 9.0000 102977473 65 42000 35.0000 =====================s3.cqkr.huayugame.com================================== passportId level num h_count 103214239 65 6000 5.0000 103048907 70 1200 1.0000 103166121 61 2400 2.0000 102906791 64 1200 1.0000 103259853 63 1200 1.0000 103268837 65 1200 1.0000 103270689 69 3600 3.0000
