Today is the next day after a long holiday, a lot of colleagues in the company have been tained at home because of holiday overtime, I have just completed a project, very empty, a mess online for a day, at 3:00 pm, I want to comfort myself, so I look at it. After a while, it is about MySQL table type InnoDB, summarizing the following
1 Support ACID, support transaction (SET AutoCommit = 0), not like Myisam as file saving, size exceeding the size of the operating system file size
2 Supports automatic growth type (Auto_Incream), which can not assign values or assign the value of the current maximum when the column is added.
3 Support foreign key constraints
