How do I create a MySQL database, tables, and insert (store) data into newly created tables?
MySQL is a free and open source database management system. You need to use sql commands to create database. You also need to login as mysql root user account. To create a database and set up tables for the same use the following sql commands:
1. CREATE DATABASE – create the database. To use this statement, you need the CREATE privilege for the database.
2. CREATE TABLE – create the table. You must have the CREATE privilege for the table.
3. INSERT – To add/insert data to table i.e. inserts new rows into an existing table.
Procedure for creating a database and a sample table
Login as the mysql root user to create database:
$ mysql -u root -pSample 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");To display all rows i.e. data stored in authors table, enter:
mysql> INSERT INTO authors (id,name,email) VALUES(3,"Tom","tom@yahoo.com");
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)
