Each user session has a search path of schemas. Vertica uses this search path to find tables and user-defined functions (UDFs) that are unqualified by their schema name.
You can use the CURRENT_SCHEMA function to display the name of the current schema (i.e., the first “valid” schema in the user’s search path).
Example:
dbadmin=> SELECT user;
current_user
--------------
dbadmin
(1 row)
dbadmin=> SHOW search_path;
name | setting
————-+—————————————————
search_path | “$user”, public, v_catalog, v_monitor, v_internal
(1 row)
dbadmin=> SELECT current_schema;
current_schema
—————-
public
(1 row)
dbadmin=> CREATE SCHEMA dbadmin;
CREATE SCHEMA
dbadmin=> SELECT current_schema;
current_schema
—————-
dbadmin
(1 row)
dbadmin=> CREATE TABLE my_test (c INT); — No SCHEMA specified
CREATE TABLE
dbadmin=> SELECT table_schema FROM tables WHERE table_name = ‘my_test’;
table_schema
————–
dbadmin
(1 row)
Have fun!

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!
