The DDL Operator Function in a Teradata PT Job
When you use the DDL operator in a Teradata PT job, Teradata PT directs an instance
of the DDL operator to:
Log on to the Teradata Database using your user name, password, Teradata Database,
and account ID information specified in the job script.
The operator terminates when scripts contain invalid or unsupported statements.
Submit a request (this can be one statement or multiple statements) to the Teradata
Database and processes returned parcels from these statements.
Issue, if an error occurs, an error message and terminate, unless the error is specified
in the ErrorList attribute, in which case the DDL operator ignores the error and continues
processing the job.
Log off the Teradata Database.
Put out an end status indicating how many requests succeeded, failed, or were ignored.
Resume, in the case of a restart, at the group that was being executed, but failed
to complete, in the previous execution.
