Note: This code works in PostgreSQL databases, but might not work in other SQL database systems (e.g. MySQL).
- Create table called adventurers CREATE TABLE adventurers ( - string variable name varchar(255), - integer variable age int, - string variable race varchar(255), - string variable weapon varchar(255) )
- Insert into the table adventurers INSERT INTO adventurers (name, age, race, weapon) VALUES ('Fjoak Doom-Wife', 28, 'Human', 'Axe'), ('Alooneric Cortte', 29, 'Elf', 'Bow'), ('Piperel Ramsay', 35, 'Elf', 'Sword'), ('Casimir Yardley', 14, 'Elf', 'Magic')
Retrieve Only Two Rows
- Retrieve rows from table SELECT * FROM adventurers - Shuffle randomly ORDER BY RANDOM() - Retrieve two rows LIMIT 2

Two Machine Learning Fields
There are two sides to machine learning:
- Practical Machine Learning:This is about querying databases, cleaning data, writing scripts to transform data and gluing algorithm and libraries together and writing custom code to squeeze reliable answers from data to satisfy difficult and ill defined questions. It’s the mess of reality.
- Theoretical Machine Learning: This is about math and abstraction and idealized scenarios and limits and beauty and informing what is possible. It is a whole lot neater and cleaner and removed from the mess of reality.
