SELECT COUNT(*) FROM fake_apps;

The fastest way to calculate the number of rows in a table is to use the COUNT() function.

COUNT() is a function that takes the name of a column as an argument and counts the number of rows where the column is not NULL. Here, we want to count every row so we pass * as an argument.
