sql_mode

show global variables like '%mode%';

sql_mode='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION'

其中如果为支持给表名加上双引号可以添加上选项ANSI_QUOTES，即有：
sql_mode='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION,ANSI_QUOTES'

但是这样会遇到下面这样的问题，会把root.default当成表来对待，因此，尽量避免使用该参数。
