servives.msc Turn on the computer service to see the startup of MySQL.
net stop MySQL Stop MySQL running
net start MySQL Start MySQL
Note: sometimes you need administrator status, otherwise it will not work.
There are two ways:
1 Connect to database: MySQL -u+ username -p+ user password -hlocalhost -P3306 (local do not lose -h and -P)
mysql -uroot -padmin -h127.0.0.1 -P3306
If you are a local visitor, you don’t need to add -h and -P.
2 After the installation of MySQL, a command window will be automatically produced and can be used directly.
Open the database service:
Use a database:
use database MySQL;
Look at the table of the database:
Create a new database:
create database demoBase;
Delete a database:
drop database demoBase;
Pay attention to the semicolon.
