[ECODP-dev] ODP-291

[John Glover]

Hi Dimitrios,

As discussed on the call earlier, here is the query that is being run to
view the most popular datasets in release 09:

        SELECT most_popular.url, most_popular.running_total,
               package.name, package.title
        FROM (
            SELECT
                url
              , running_total
              , regexp_split_to_array(url, E'\\/') as name
            FROM tracking_summary
            WHERE
                running_total > 0
            AND url LIKE('%/dataset/%')
            AND tracking_date = (select max(tracking_date)
                                 from tracking_summary)
            ) as most_popular
        LEFT JOIN package
        ON most_popular.name[array_length(most_popular.name, 1)] =
package.name
        WHERE package.name IS NOT NULL
        ORDER BY
            running_total DESC

The problem here seems to be the line 'AND tracking_date = ...', which is
selecting the global max instead of the most recent max for a given dataset.

Regards,
John
