R
Record Mode
A Teradata Database response mode which returns non-null fields (except for large objects) as unformatted data.
records
A formatted record, in Teradata Database terms, consists of a record created by a Teradata Database utility, such as BTEQ, where the record is packaged with begin- and end-record bytes specific to Teradata Database. Unformatted records are any records not originating on Teradata Database. These files contain records that must be defined before loading onto Teradata Database.
row
Used to represent a record in a file or a tuple in relational modeling.
run file
A script that is not contained within the SYSIN file, but rather executed through use of the .RUN BTEQ command.
S
script
A file that contains a set of BTEQ commands or SQL statements or both.

T
TDP
Teradata Director Program
TDPID

Teradata SQL
The Teradata Database dialect of the relational language SQL, having data definition and data manipulation statements. A data definition statement would be a CREATE TABLE statement and a data manipulation statement would be a data retrieval statement (a SELECT statement).
U

Unicode®
The universal character encoding, maintained by the Unicode® Consortium
http://www.unicode.org. The encoding standard provides the basis for processing, storage, and interchange
of text data in any language in all modern software and information technology protocols.
Within this manual, Unicode® refers to either UTF-8 or UTF-16.
UTF-8
Code scheme that uses a sequence of one to four bytes to represent each Unicode® scalar value.
UTF-16
Code scheme that uses a single 16-bit code unit to represent the most common 63k Unicode® scalar values, and a pair of 16-bit code units, called surrogates, to encode supplementary characters in Unicode®.
V
varbyte
A data type that represents a variable-length binary string.
varchar
A data type that represents a variable-length non-numeric character.
vargraphic
A data type that represents a variable-length string of characters.
W
