perl 分析binlog 定位错误sql 思路

1. 获取需要的binlog 日志:
[root@zjzc01 binlog]# mysqlbinlog --start-datetime='2016-08-01 00:00:00' --stop-datetime='2016-08-11 12:00:00' mysql-bin.00006* >a.txt

2.获取对应行的记录 匹配 update ProductAccess

[root@zjzc01 binlog]# cat get_num.pl
open (A,"<","a.txt");
open (B,">","b.txt");
$a=$ARGV[0];
$b=$ARGV[1];
 while (<A>) {
              $num++;
              if (( $_ =~/$a\s+$b\s+/i ) or ($_ =~/$a\s+`zjzc`.`$b`\s+/i) )  { $c = $num;print B ("$c\n"); };
               }
               }

[root@zjzc01 binlog]# perl get_num.pl update ProductAccess

3.
[root@zjzc01 binlog]# cat sed.sh
 cat b.txt | while read A
do
#num1=`expr $A - 5`
num1=`expr $A - 5`
num2=`expr $A + 5`
#num2=`expr $A + 30`
sed -n ''$num1','$num2'p' a.txt
done

取上下5行

4.
[root@zjzc01 binlog]# sh ./get_sql.sh update ProductAccess >aa.sql
[root@zjzc01 binlog]# cat aa.sql | grep 551 | grep ProductAccess
UPDATE `zjzc`.`ProductAccess` SET `yieldForFirst`='0.0120000000' WHERE `productSn`='551'
