2.1 Character Set Selection
Utf8 is generally selected, and utf8mb4 can also be selected. The difference is that utf8mb4 is compatible with utf8 and can represent more characters than utf8.If you are interested, you can take a look at the difference, unicode The coding area is from 1 to 126It belongs to the traditional utf8 area. Below 126 lines is the utf8mb4 expansion area. If you don't need the expansion area characters, setting it is just a waste of space.
2.2 Selection of sorting rules
There are generally three kinds of collation rules: utf8_general_ci, utf8_general_cs, utf8_bin.
(1) The full name of ci is case insensitive, which means case insensitive;
(2) cscase sensitivewrite;
(3) bin is stored in binary data and is case-sensitive.

Let me introduce myself first. The editor graduated from Shanghai Jiaotong University in 2013. I worked in a small company and went to big factories such as Huawei and OPPO. I joined Alibaba in 2018, until now.I know that most junior and intermediate java engineers want to upgrade their skills, they often need to explore their own growth or sign up to study, but for training institutions, the tuition fee is nearly 10,000 yuan, which is really stressful.Self-learning that is not systematic is very inefficient and lengthy, and it is easy to hit the ceiling and the technology stops.Therefore, I collected a "full set of learning materials for java development" for everyone. The original intention is also very simple. I hope to help friends who want to learn by themselves but don't know where to start, and at the same time reduce everyone's burden.Add the business card below to get a full set of learning materials
