How to Create a MySQL Database on Linux

[sherlyk]

First you can login as root on your mysql server using:

mysql -u root -p

If a password is required,

$ mysql -u root -p
Enter password:

You should now be at a MySQL prompt that looks very similar to this:

mysql>

We can now create a database by run command:

CREATE DATABASE tutorial_database;

Query OK, 1 row affected (0.00 sec)

The database name we have chosen already exists, run command:

CREATE DATABASE IF NOT EXISTS tutorial_database;

Query OK, 1 row affected, 1 warning (0.01 sec)

If we leave the "IF NOT EXISTS" option off, and the database already exists, we will receive the following error:

ERROR 1007 (HY000): Can't create database 'tutorial_database'; database exists

To view a list of the current databases, use run command:

SHOW DATABASES;

[admin]

To see all tables in a database, run

user DB_NAME;
show tables;

Commands you run inside MySQL command prompt are called SQL (Structured Query Language) statements. All SQL statements ends with semicolon (;)

fwh@fwhlin:~ $ mysql
Welcome to the MySQL monitor.  Commands end with ; or \g.

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
