Show column name and data type in Teradata?

Question

Is there a way to get column name and data type in a Teradata SQL Assistant 15.0view?

In Oracle 11g you can do something like desc tablename and get a script result set of the following :

Name Null Type

---

test_id NOT NULL NUMBER(19)
test_name VARCHAR2(255)
test_department VARCHAR2(255)
test_year TIMESTAMP(6)
test_external_id NUMBER(10)

So far I've tried help view viewname and the result provides all column names but the values for the data type are all nulls.

Answer 1

You can use "SHOW VIEW VIEW_NAME" or "HELP COLUMN VIEW_NAME.*" to get all column names and datatype in the view.

Example

HELP COLUMN dbc.Allspace.*

OUTPUT

MaxProfileTemp  F       Y           ---,---,---,---,--9             8   

Answer 2

you can use : help table tablename (in case of tables) and help view viewname in case of views
