I have a table:
I have a query which gives me
And I want something like this:
Query used for above result is:
select ucountry,sum(Males) Males,sum(females ) Females from (
select ucountry,
case when gender = 'M' then count(1) else 0 end as Males,
case when gender = 'F' then count(1) else 0 end as females
from testing.test_users
group by ucountry, gender
) a group by ucountry;
I am definitely not doing the best thing here. Any thing you guys think would be better?
If you're trying to count the number of males and females in each country:
select ucountry,
sum(case when gender = 'M' then 1 else 0 end) as males,
sum(case when gender = 'F' then 1 else 0 end) as females
from testing.test_users
group by ucountry
If you are using PostgreSQL then you can also user FILTER
select ucountry, COUNT(*) FILTER (WHERE gender = 'M') males,
COUNT(*) FILTER (WHERE gender = 'F') females from testing.test_users group by ucountry
You should apply GROUP BY only on ucountry column. Use below query to get expected result in SQL Server :
SELECT
ucountry,
SUM(IIF(Name = 'M', 1, 0)) males,
SUM(IIF(Name = 'F', 1, 0)) females
FROM testing.test_users
GROUP BY ucountry
