MySQL, like any other relational database management system, has a SELECT statement in its structure. This is not surprising, because databases store information in themselves primarily in order to retrieve it when there is a need for it. The MySQL select from SELECT statement allows you to do this in many different ways, providing a large set of tools.
MySQL installation
MySQL is implemented both under Windows and under Linux. To install MySQL Ubuntu, it is enough to run two commands in the terminal of this OS:
- Sudo apt-get install mysql-server.
- Sudo apt-get install mysql-client.
For MySQL Windows, just download the appropriate installation packages from the official DBMS website and run them.
