The COUNT() Function

COUNT() is a function that allows you to count rows in a table or count how many rows match certain criteria.

copy

To count the total number of rows in the table, we can use the following syntax:

12
SELECT COUNT(*) FROM country;
copy

Here is the country table we are working with:
