I have been googling and searching this site but cant find an answer to this simple question.

How can I list or select all the columns of a table in Teradata?

Answer 1

different possibillities

Help table <TableName> -- All columns of a table 
Help columns  <ViewName>.* -- All columns of a View
Show table <TableName> -- DDL of table
Show view <ViewName> -- DDL of View
show select * from  <ViewName>-- DDL of base table in a view

or select from system table.

SELECT ColumnName 
FROM dbc.columnsV
WHERE DatabaseName = 'DB_NAME' and
TableName = 'table_name';
