Because SQL has a built-in, nonprocedural, method to handle default values (see the default value control phrases DEFAULT and WITH DEFAULT in Teradata Vantage™ - Data Types and Literals, B035-1143), no special coding is required on the part of users. Note that if no defaults are specified for a column and it is not defined as NOT NULL, then SQL automatically inserts nulls to represent any information missing from an INSERT request.
