The SELECT statement is used to choose what data we want, either all columns (*) or specific ones.
The WHERE clause helps filter rows based on conditions like ID, country, or population.
To avoid duplicate results, DISTINCT is used, while pattern matching with LIKE helps search data based on formats. Aggregate functions like COUNT are used to perform calculations on data.
Overall idea
SELECT - what you want
FROM - where to get it
WHERE - filter data
DISTINCT - remove duplicates
COUNT - calculate values
