Chapter 3: Teradata TPump Commands
NAME
lllll = is the low order 5 digits of the logon sequence number returned by the database from the
.LOGON command.
This variable is not set until created with the NAME command, or with the first BEGIN LOAD
by default. Any attempt to use it before a NAME command is issued (or before the first
BEGIN LOAD if there is no NAME command), results in a syntax error. This variable is
significant because it is used by Teradata TPump when composing default names for various
database artifacts, namely the error table and Teradata TPump-created macros.
Note: If serialization for two or more DML statements is required, they cannot be put in
different partitions. Serialization requires that all DML statements with identical hash values
of the rows be submitted from the same session.
