Greetings, I am trying to build a query that will provide me with the totals of all records (some records are recurring) between two dates. I am stuck at the following query:
SELECT DISTINCT Country, COUNT(Country) as Count, Date
From Da开发者_StackOverflowtaSet
GROUP BY Country, Date
ORDER BY Country HAVING Date>'1/1/2000'
Thanks in advance.
SELECT DISTINCT Country, COUNT (Country) AS COUNT
FROM DataSet
WHERE Date BETWEEN '01-01-2010' AND '01-01-2011'
GROUP BY Country
ORDER BY Country
You should not group by date because you'll get for every date a row
SELECT Country, COUNT(DISTINCT Country) as "Count"
FROM DataSet GROUP BY Country, Date
HAVING Date>'1/1/2000';
because HAVING
are not set with order by ok coorect it
