Procedure for creating a database and a sample table
Login as the mysql root user to create database:
$ mysql -u root -p
Sample outputs:
mysql>
Add a database called books, enter:
mysql> CREATE DATABASE books;
Now, database is created. Use a database with use command, type:
mysql> USE books;
Next, create a table called authors with name, email and id as fields:
mysql> CREATE TABLE authors (id INT, name VARCHAR(20), email VARCHAR(20));
To display your tables in books database, enter:
mysql> SHOW TABLES;
Sample outputs:
+-----------------+
| Tables_in_books |
+-----------------+
| authors         |
+-----------------+
1 row in set (0.00 sec)
Finally, add a data i.e. row to table books using INSERT statement, run:
mysql> INSERT INTO authors (id,name,email) VALUES(1,"Vivek","xuz@abc.com");
Sample outputs:
Query OK, 1 row affected (0.00 sec)
Try to add few more rows to your table:
mysql> INSERT INTO authors (id,name,email) VALUES(2,"Priya","p@gmail.com");
mysql> 
INSERT INTO authors (id,name,email) VALUES(3,"Tom","tom@yahoo.com");
To display all rows i.e. data stored in authors table, enter:
mysql> SELECT * FROM authors;
Sample outputs:
+------+-------+---------------+
| id   | name  | email         |
+------+-------+---------------+
|    1 | Vivek | xuz@abc.com   |
|    2 | Priya | p@gmail.com   |
|    3 | Tom   | tom@yahoo.com |
+------+-------+---------------+
3 rows in set (0.00 sec)
