UNICODE is not supported atthis time.3 When character inputs are larger than 256 characters, the results depend on the session modeassociated with the Teradata connection.3 In ANSI session mode (the typical SAS default mode) passing a character field larger than256 results in a string truncation error.3 In Teradata session mode, character inputs larger than 256 characters are silentlytruncated to 256 characters before the format is applied. The SAS/STAT procedures thathave been enhanced for in-database processing use the Teradata session mode.4 The SAS_PUT( ) function has a VARCHAR data type for its first argument when the valuepassed has a data type of CHARACTER. Therefore, columns with a data type of CHARACTERhave their trailing blanks trimmed when converting to a VARCHAR data type.The SAS_PUT( ) function does not support direct use of the Teradata data typesshown in Table 28.4 on page 821. In some cases, unsupported data types can beexplicitly converted to a supported type by using SAS or SQL language constructs. Forinformation about performing explicit data conversions, see “Data Types for Teradata”on page 838 and your Teradata documentation.
