Example:
dbadmin=> SELECT * FROM (
dbadmin(> SELECT TRUNC(audit_start_timestamp)::DATE the_date, usage_percent * 100 AS usage_percent
dbadmin(> FROM license_audits
dbadmin(> WHERE audited_data = 'Total'
dbadmin(> LIMIT 1 OVER (PARTITION BY TRUNC(audit_start_timestamp) ORDER BY audit_start_timestamp DESC)
dbadmin(> ) foo
dbadmin-> ORDER BY 1 DESC
dbadmin-> LIMIT 7;
the_date | usage_percent

Looks like I’m going to need add some new Vertica license soon!

James Knicely
Vertica Field Chief Technologist
I've had the privilege of working with many database technologies in my career. But after being introduced to Vertica in May of 2011 as a client, I was hooked on the new technology after witnessing a query run in milliseconds that had previously ran for hours on the legacy database we had in place. It was then that I knew I wanted to eventually join the Vertica team, and 4 years later I did! I am currently a Vertica evangelist and am ready to help you get on board! Please feel free to reach out to me with any questions you have about Vertica and make sure to follow my Vertica Quick Tips!
