838 Data Types for Teradata 4 Chapter 28Example 1: Unusual Teradata Table Namelibname unusual teradata user=testuser password=testpass;proc sql dquote=ansi;create view myview asselect * from unusual."More names";proc print data=myview;run;Example 2: Unusual Teradata Column NamesSAS/ACCESS automatically converts Teradata column names that are not valid forSAS, mapping such characters to underscores. It also appends numeric suffixes toidentical names to ensure that column names are unique.create table unusual_names( Name$ char(20), Name# char(20),"Other strange name" char(20))In this example SAS/ACCESS converts the spaces found in the Teradata columnname, OTHER STRANGE NAME, to Other_strange_name. After the automaticconversion, SAS programs can then reference the table as usual.libname unusual teradata user=testuser password=testpass;proc print data=unusual.unusual_names; run;Output 28.3PROC PRINT DisplayName_ Name_0 Other_strange_nameData Types for TeradataOverviewEvery column in a table has a name and data type. The data type tells Teradata howmuch physical storage to set aside for the column, as well as the form in which to storethe data. This section includes information about Teradata data types, null values, anddata conversions.SAS/ACCESS 9 does not support these Teradata data types: GRAPHIC,VARGRAPHIC, and LONG VARGRAPHIC.Binary String DataBYTE (n)specifies a fixed-length column of length n for binary string data. The maximumfor n is 64,000.VARBYTE (n)specifies a varying-length column of length n for binary string data. Themaximum for n is 64,000.
