By default, the interface
for your DBMS converts each SAS data type to a predetermined DBMS
data type when writing data to your DBMS. When you need a different
data type, use DBTYPE= to override the default data type.
Teradata
Details: In Teradata, you can use DBTYPE= to
specify data attributes for a column. See your Teradata CREATE TABLE
documentation for information about the data type attributes that
you can specify. If you specify DBNULL=NO for a column, do not also
use DBTYPE= to specify NOT NULL for that column. If you do, 'NOT NULL'
is inserted twice in the column definition. This causes Teradata to
generate an error message.
