Graphic Data Types
To define double‑byte character set data, the GRAPHIC, VARGRAPHIC, and LONG VARGRAPHIC data types are supported. Teradata TPump accepts GRAPHIC data in the input data set or file containing the Teradata TPump statements to be executed.
The FIELD and FILLER statements that describe the input data are the statements affected by GRAPHIC data support. Table 19 lists the GRAPHIC data types that can be specified for the datadesc option in the FIELD or FILLER statement.
