Let's dig into our database. This database has 9 columns:
model- model of the caryear- year of manufactureprice- car price in Eurostransmission- type of gearboxmileage- miles drovefueltype- engine fuel typetax- road taxmpg- miles per gallonenginesize- engine size in liters.
To extract certain columns you need to select them by their names, like:
12SELECT column1, column2, column3 FROM table_name
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.
