Job Objective

Note: If the Teradata Database table is populated, use the Update operator for the load operation.

Sample Script

For the sample script that corresponds to this job, ee the following script in the sample/userguide directory:

PTS00014: Batch Directory Scan.


This job uses:

  • DDL operator because it can DROP/CREATE staging tables and target tables prior to loading and DROP unneeded tables at the conclusion of the job.
  • DataConnector operator because it is the only producer operator that reads data from external flat files.
  • Load operator because it is the consumer operator that offers the best performance for high speed writing of a large number of rows into an empty Teradata Database table.
