- 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')
Create An If Else Statement
There are a number of ways to do if-else in SQL, my prefered way is the
- Retrieve all rows SELECT *, - The case when race = elf, return "Elvish" CASE WHEN race = 'Elf' THEN 'Elvish' - When race = human, return "Human" WHEN race = 'Human' THEN 'Human' - Call this column "race" END AS race - Do this from the adventurers table FROM adventurers
Python Example for Beginners
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.
