韩锋大师分享了一个mysql的性能优化工具，一个能自动采集SQL优化相关各种信息的python脚本，对于优化人员而言，这能省不少事，赞！
试用了一下，发现在mysql5.7下，运行不起来，细节上还是有好几个坑的，费了一些周折，终于把坑踩完了，现在把细节说明一下，并把修改后的SQL分享出来；
问题1：调用脚本时，若SQL是用单引号包含（韩老师就是这么示范的：python mysql_tuning.py -p tuning_sql.ini -s 'select xxx），但这样会报错，解决办法：用双引号分隔，如：python mysql_tuning.py -p tuning_sql.ini -s "select * from employees.dept_emp"这样就没问题；

问题2：没有引用string单元，在使用string.atoi时会报错，解决办法：import string；

问题3：mysql5.7后，infomation_schema的几个表INFORMATION_SCHEMA.GLOBAL_VARIABLES、INFORMATION_SCHEMA.SESSION_VARIABLES、INFORMATION_SCHEMA.SESSION_STATUS要替换成performance_schema下的；

问题4：在显示执行计划时，table与type也是有可能是NULL的，要做空值处理，另外没有显示partitions栏位；

问题5：p_after_status[key]有可能是小数，所以用int去转换会报错，需要用float;

问题6：db_name显示成user_pwd了，这个或者不算问题；

修改后的脚本如下：
