??Foreword

Database is a must-have technology for a programmer, so I will share my MySql language learning path.This blog will share the installation of MySql from zero to one, configuring environment variables, building databases and tables, etc. The subsequent additions, deletions, changes, views, indexes, transactions, and JDBC technologies will also be included in this column one after another.Update, interested friends can subscribe for free~

I. MySql installation and environment configuration

MySql download and installation

1. Official website link, click to jump MySQL download
2. Click the icon "Chinese" after the jump link
   
3. Click on GPL
   
   Continue to follow the icon and click
   
   click download
   
4. This style is after the download is complete, double click to start the download
   
5. Be sure to remember the password you set when downloading, and click next for other things

Configuring environment variables

Check if you can log in to the database first

1. Open the bin directory where MySql is located, enter cmd to enter the black window
   
2. Enter mysql -u root -p, then enter the password you set during installation, which is consistent with the picture, indicating success
   

Configuring environment variables

1. Copy MySql's binpath
2. Find the environment variable of the system, enter the copied bin path after creating a new one and confirm it
   

Second, tools for building databases

1. You can search and download navicat12018_premium_cs_x64 in CSDN resources, or private letter bloggers can also
2. Test connection to database after download is complete
   
3. If the connection fails, refer to the solution below

Three, the establishment of the database and the establishment of the table

Database creation

1. First connect to MySql database, the interface is as follows:
   
2. Click New Query and enter create database if not exists database name, the effect is as follows:
   

Table Creation

1. Create a new query again and write the code:

   create table if not exists myTable(
   name varchar(20) primary key,
   age int not null
   )

This is just a brief demonstration of the establishment of the table. Subsequent articles will introduce the knowledge points such as table constraints in detail

2. The effect is as follows:
   

Conclusion

Such a solid tutorial, I haven't collected it to build a MySQL environment!If the Navicat tool is missing, you can privately message the blogger to get it. If you have any questions during the installation process, you can also ask me to answer them. Finally, it is not too much to ask for a three-link support~

Let me introduce myself first. The editor graduated from Jiaotong University in 2013. I worked in a small company and went to big factories such as Huawei and OPPO. I joined Ali 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
