The LOG_QUERIES system table provides summary information about those operations.
Example:
dbadmin=> SELECT issued_time,
dbadmin-> user_name,
dbadmin-> audit_type,
dbadmin-> request_type,
dbadmin-> request
dbadmin-> FROM log_queries
dbadmin-> WHERE session_id = current_session()
dbadmin-> ORDER BY issued_time DESC;
issued_time | user_name | audit_type | request_type | request
-------------+-----------+------------+--------------+---------
(0 rows)
dbadmin=> CREATE TABLE test_table (c1 INT, x1 VARCHAR(10));
CREATE TABLE
dbadmin=> ALTER TABLE test_table RENAME x1 TO c2;

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!
