Count columns according to dates in SQL

Question

I need help with a SQL statement. The goal is to count the amount of alarms of each date. My table looks something like this:

|----DATE----|---COUNTER---|---ALAR         


        

Answer 1

Try this instead

SELECT date, SUM(counter) FROM all_stats GROUP BY date;

"GROUP BY date" puts all the individual dates on a separate line and does the sum separately per date.

Answer 2

select date, sum(counter)
from all_stats
group by date

Answer 3

SELECT date, SUM(counter)
FROM all_stats
GROUP BY date
