Hi,
I have a table similar to this:
Country, total, recovered, death, date
USA, 30000, 2000, 1000, 3/3/22
Italy, 25000, 1500, 750, 3/3/22
UK, 20000, 1000, 500, 3/3/22
USA, 25000, 1500, 750, 3/3/21
Italy, 20000, 1000, 500, 3/3/21
UK, 15000, 1000, 500, 3/3/21
USA, 20000, 1000, 500, 3/3/20
Italy, 15000, 1000, 500, 3/3/20
UK, 10000, 500, 200, 3/3/20

Do I have to restructure it like this:
USA_total, USA_recovered, USA_death, Italy_total, Italy_recovered, Italy_death, UK_total, UK_recovered, UK_death, date
30000, 2000, 1000, 25000, 1500, 750, 20000, 1000, 500 3/3/22
25000, 1500, 750, 20000, 1000, 500, 15000, 1000, 500 3/3/21
20000, 1000, 500, 15000, 1000, 500, 10000, 500, 200 3/3/20

in order to get a single graph for “Total” that shows all countries in one graph and similarly for recovered and deaths?

Hi @abdullah2020
No, you should use GROUP BY - you never want to change your structure, but you want to be able to make every query imaginable.
So if you want to only see the numbers by date, then something like this should work:
SELECT date, SUM(total), SUM(recovered), SUM(death) FROM table GROUP BY date
This is not a Metabase question, so you’ll probably find better help in a forum specific to your database or perhaps stackoverflow.com
