Question

SELECT
reporting.station
FROM
reporting
LEFT JOIN
channel
ON
MD5(igmpurl)=reporting.station
WHERE
reporting.station!=”n/a”
ORDER BY
name;

resulting in this table:

Now I’d like to count the number of each element, which should something look like:

Note: I know about COUNT(station) which would return the number of the rows (20) but is not what I want.

Any idea how to solve this in MySQL (InnoDB)?
Many thanks and regards

SELECT
    reporting.station, COUNT(reporting.station)
FROM
    reporting
LEFT JOIN
    channel
ON
    MD5(igmpurl)=reporting.station
WHERE
    reporting.station!="n/a"
GROUP BY reporting.station
ORDER BY
    name;

Try this.
