842 Data Returned as SAS Binary Data with Default Format $HEX 4 Chapter 28Teradata Data TypeDefault SAS Format(v MOD d) MOD(v,d)TRIMN(c) TRIM(TRAILING FROM c)1 When reading Teradata data into SAS, DBMS columns that exceed 32,767 bytes are truncated.The maximum size for a SAS character column is 32,767 bytes.2 If the DECIMAL number is extremely large, SAS can lose precision. For details, see the topic“Numeric Data”.3 See the topic “Date/Time Data” for how SAS/ACCESS handles dates that are outside the validSAS date range.4 TIME and TIMESTAMP are supported for Teradata Version 2, Release 3 and later. The TIMEwith TIMEZONE, TIMESTAMP with TIMEZONE, and INTERVAL types are presented as SAScharacter strings, and thus are harder to use.When you create Teradata tables, the default Teradata columns that SAS/ACCESScreates are based on the type and format of the SAS column. The following table showsthe default Teradata data types that SAS/ACCESS assigns to the SAS formats duringoutput processing when you use the LIBNAME statement.Table 28.11Default Output Teradata Data TypesSAS Data Type SAS Format Teradata Data TypeCharacter$w.$CHARw.$VARYINGw.CHAR[w]Character $HEXw.

To display Teradata columns that contain SAS times and datetimesproperly, you must explicitly assign the appropriate SAS time or datetime display format to thecolumn.To override any default output type, use the DBTYPE= data set option.Data Returned as SAS Binary Data with Default Format $HEXBYTEVARBYTE
