ZQuery Template

Query collection for ZDB

Query Tips

• Always use date for filter queries
• Using the site_id filter would be better
• To check query results, filter the date using the past 7 days first

Query

Example #1

query meas lookup to network_cell to get site_id field, from 7 days before until yesterday with specify site_id

    select date, site_id, sum(payload_mbyte) as payload_mbyte
    from r11.meas_2g_daily m
            join network_cell n on m.network_cell_id = n.id
    where date between date_int(7) and date_int(1)
    and site_id in ('SITE_ID')
    group by date, site_id
    order by site_id, date;

Example #2

query meas lookup to network_cell to get site_id field and cluster name, from 7 days before until yesterday with specify cluster

    select date, n.site_id, cluster, sum(payload_mbyte) as payload_mbyte
    from r11.meas_2g_daily m
            join network_cell n on m.network_cell_id = n.id
            join ref_site r on n.site_id = r.site_id
    where date between date_int(7) and date_int(1)
    and r.cluster in ('CLUSTER NAME')
    group by date, n.site_id, cluster
    order by cluster, n.site_id, date;
