hi im making a sql select for the count of multiple row values where Domain == 'whatever'.
at the moment im making 5 seperate selects which take long to load and are inefficient, im asking if and how i can select the count of multiple rows in one query or atleast more efficiently than im doing now.
i am trying to select the count of rows: route, browser, device, location and referrer where the domain is equal to "whatever"
i would like the output to contain all the listed rows above in a format like this: rowname: {count: 1}
here is the table:
CREATE TABLE IF NOT EXISTS hits (
ID INTEGER PRIMARY KEY AUTO_INCREMENT,
Domain TEXT NOT NULL,
Route TEXT NOT NULL,
Timestamp INTEGER NOT NULL,
Browser TEXT,
Location TEXT,
Device TEXT,
Referrer TEXT
)
and these are the selects i have at the moment:
routes = db.run('SELECT Route, COUNT(Route) AS count FROM hits WHERE Domain = %s AND Timestamp BETWEEN %s AND %s GROUP BY Route', (domain, d1, d2))
browsers = db.run('SELECT Browser, COUNT(Browser) AS count FROM hits WHERE Domain = %s AND Timestamp BETWEEN %s AND %s GROUP BY Browser', (domain, d1, d2))
locations = db.run('SELECT Location, COUNT(Location) AS count FROM hits WHERE Domain = %s AND Timestamp BETWEEN %s AND %s GROUP BY Location', (domain, d1, d2))
screens = db.run('SELECT Device, COUNT(Device) AS count FROM hits WHERE Domain = %s AND Timestamp BETWEEN %s AND %s GROUP BY Device', (domain, d1, d2))
referrals = db.run('SELECT Referrer, COUNT(Referrer) AS count FROM hits WHERE Domain = %s AND Timestamp BETWEEN %s AND %s GROUP BY Referrer', (domain, d1, d2))```
The following works in SQL fiddle. The question is tagged with mysql and python, so please specify further what engine you are using if you need further assistance:
SELECT
COUNT(Route) AS route_count,
COUNT(Browser) AS browser_count,
COUNT(Location) AS location_count,
COUNT(Device) AS device_count,
COUNT(Referrer) AS referrer_count
FROM
hits
WHERE
Domain = 'whatever'
AND Timestamp BETWEEN '00:00' AND '12:00'
