bookSELECTing certain columns

Let's dig into our database. This database has 9 columns:

  1. model - model of the car
  2. year - year of manufacture
  3. price - car price in Euros
  4. transmission - type of gearbox
  5. mileage - miles drove
  6. fueltype - engine fuel type
  7. tax - road tax
  8. mpg - miles per gallon
  9. enginesize - engine size in liters.

To extract certain columns you need to select them by their names, like:

12
SELECT column1, column2, column3 FROM table_name
copy

Please note, that SQL is also case-insensitive to column names, i.e. if the column has name id both notations id and ID will be interpreted the same.

Tarea

Extract columns model, year, and price from the audi_cars database.
