MySQL installation test"

After installing MySQL, you also need to test it to determine whether MySQL is successfully installed. The visualization of MySQL is different from that of SQL Server. There are two test methods for MySQL: 1. Test using MySQL commands; 2. Install a client to test the connection. Because the two methods are visualized and easy to operate, we will not detail them in detail. Here we will mainly introduce MySQL test commands.

Step 1In the open DOS window, Enter command 1 to enter the directory mysqlbin,

Step 2Enter the command "mysql-u username-p ",

Step 3Enter the password (four or more passwords previously set) to MySQL,

Step 4Enter the command "use test" to open the database.

Step 5Run the "show databases;" command to display the Database List.

 

In addition, add some other basic MySQL commands:

1. Change the password

Mysqladmin-u username-p old password New password

For example, change the root password to 1212.

Mysqladmin-uroot-p1212 password 123456

2. Add new users

Grant select on database. * to username @ login host identified by "password"

3. display the Database List.

6. database creation:

7. Create a table:

8. Delete databases and tables:

9. Clear the records in the table:

10. Display records in the table:
