1、Mysql中MD5值做表名报错的问题及解决方法

写爬虫的时候需要MD5做表名,但是一部分会报错,其他的却会工作的很好!例如978ea04f9bdadd36d1f919520f20ac47做表名就能正常工作,而8e6a968cdadefeeae6c25e050080e537却不行!原因是什么呢?

因为MD5中会含XeX字符,例如1e或2e2,因为类似1e+1的表达式比较模糊。根据上下文,它可以解释为表达式1e +1或数字1e+1。所以:使用MD5产生表名时应仔细,因为它可能产生不合法的表名,如上所述。

解决方法:

1、既然问题根源在于e这个字符,那么可以替换掉所有e这个字符,用str.replace("e","new")即可;

2、使用Mysql的识别符"`",键盘1右边那个键。
