The Subscriber Number

easySQLAggregation

StreamVerse opens every all-hands with the same slide, and the same number sits at the top of it: how many people are subscribed right now. Nobody wants a list of names on that slide — they want the one figure, in a column the deck can point at.

subscribers — one row per person who pays for StreamVerse. plan is one of basic, standard or premium; country is a two-letter market code; signup_date is the day they signed up.

id name plan signup_date country
1 Ana Torres premium 2022-11-01 US
2 Ben Osei basic 2023-01-15 UK
3 Chloe Martin standard 2023-02-20 US
4 Dev Malhotra premium 2023-03-10 IN
5 Ella Novak basic 2023-04-05 UK

The table already exists in the database — there is nothing to create or load.

Task: Write a query that returns exactly one row with one column, total_subscribers, holding how many subscribers are on file.

Example output

If three hundred and twelve subscribers were on file, the single row would read:

total_subscribers
312
