students 

students is a database which i wanted to access.
How to access and query this database? Should i use sudo su commands?

Answer 1

First you determine the database type, where it is located (host address), the username, and password to access it. The you determine if you have the appropiate client to connect to it. Then you connect and run your sql query.

Is this a sqllite or berkly db? Mysql?

If MySql, and you have the mysql client installed, and the db is on the localhost… do this:

mysql -u username -p

Where username is the username to connect. It will prompt for password. When at the mysql prompt see all dbs with this:

show databases;

Select a db like this:

use somedatase;

Then query away.
