Create Table Of Superheroes
- Create a table called SUPERHEROES. CREATE OR REPLACE TABLE SUPERHEROES ( - Column called ID allowing up to five characters "ID" VARCHAR (5), - Column called NAME allowing up to 100 characters "NAME" VARCHAR(100), - Column called ALTER_EGO allowing up to 100 characters "ALTER_EGO" VARCHAR(100), - Column called BANK_BALANCE allowing 38 digits with 2 after the decimal point "BANK_BALANCE" NUMBER(38, 2), - Column called AGE allowing 3 digits with 0 after the decimal point "AGE" NUMBER(3, 0) );
Insert Rows For Each Superhero
- Insert rows into SUPERHEROES INSERT INTO SUPERHEROES - With the values VALUES ('XF6K4', 'Chris Maki', 'The Bomber', '-100.20', '14'), ('KDEJ4', 'Rich Richardson', 'Mr. Money', '233.20', '12'), ('KD5SK', 'Donny Mav', 'Nuke Miner', '200.30', '59');
Convert VARCHAR String To INTEGER
- Select the BANK_BALANCE column converted into an integer SELECT CAST(BANK_BALANCE AS INTEGER) - From the SUPERHEROES table FROM SUPERHEROES;
Convert VARCHAR String To INTEGER (Alternative)
- Select the BANK_BALANCE column converted into an integer SELECT BANK_BALANCE::INTEGER - From the SUPERHEROES table FROM SUPERHEROES;
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.
