Glossary
join:
result.
A SELECT operation that combines information from two or more tables to produce a
L
locks: Teradata load/unload utilities automatically lock any table being loaded and free a
lock only after an END LOADING statement is entered. Therefore, tables are only available
when the operation is complete.
log: A record of events. A file that records events. Many programs produce log files. Often a
log file is looked at to determine what is happening when problems occur. Log files have the
extension “.log”.
M
macro: A file created and stored on Teradata Database and executed in response to a
Teradata SQL EXECUTE statement. Each macro execution is implicitly treated as a
transaction.
methods: In object-oriented programming, programming routines by which objects are
manipulated.
MultiLoad: Teradata MultiLoad utility. A command-driven utility that performs fast, highvolume
maintenance functions on multiple tables and views of Teradata Database.
multiset tables:
Tables that allow duplicate rows.
N
name: A word supplied by the user that refers to an object, such as a column, database,
macro, table, user, or view.
network-attached: A computer that communicates over the LAN with a server (for
example, Teradata Database).
notify exit: A user-defined exit routine that specifies a predefined action to be performed
whenever certain significant events occur during a job. For example, by writing an exit in C
(without using CLIv2) and using the NotifyExit attribute, the routine can detect whether a job
succeeds or fails, the number of loaded records, the return code for a failed job, and so on.
null:
The absence of a value for a field.
O
object: In object-oriented programming, a unique instance of a data structure defined
according to the template provided by its class. Each object has its own values for the variables
belonging to its class and can respond to the messages, or methods, defined by its class.
owner: In Teradata SQL, the user who has the ability to grant or revoke all privileges on a
database. By default, the creator of the database is the owner, but ownership can be transferred
from one user to another by the GIVE statement.
