Column and other table metadata information in Teradata dbc tables

All Teradata system tables are stored under DBC schema.


For columns, it is dbc.columns

select * from dbc.columns

For views, it is dbc.tables with a filter on a column something named table_type 'V' (where V stands for Views)

select * from dbc.tables where tablekind = 'V'

In Teradata DBC.Tables contains many of the objects that exist on the system. (e.g. Stored Procedures, UDF, Triggers, Macros, Views, Tables, Hash Index, Join Index, etc.) The column Table Kind is used to identify the type of object.
