Is there a schema I can look in or a query that I can run to see all the Netezza system or metadata tables?
I know about _v_table
, _v_view
, _v_relation_column
, and _v_groupusers
.
I know there are many others and I would like the definitive list.
Documentation on each would be nice too, but I will settle for just a list.
I looked at How list of netezza system tables/views? but I am looking for a list of system tables. The author of that question is looking to pull specific metadata about the tables on his system.

I don't know of a way to access such a list via a query but IBM provide a list of user views and system views in their Knowledge Centre. I assume those pages are public because their website tells me I'm not currently logged in (but it's not the most user-friendly of sites in terms of authentication so I may be wrong).
As CraigBoyd pointed out in a comment,
SELECT * FROM _V_SYS_VIEW;
will give you the list of system views.SELECT * FROM _V_VIEW;
will also list some of the system views plus any user-defined views. I can't tell why some views are included in_V_SYS_VIEW
but not in_V_VIEW
.
