Sample Script

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

PTS00020: Exporting Data and Processing It with an Access Module.

Rationale

The job uses:

  • Export operator because it is the fastest at extracting large amounts of data from a Teradata Database.
    The SQL operator extracts data more slowly than the Export operator. Use the SQL Selector operator only if the Teradata Database is short on load slots, because the SQL Selector operator does not use Teradata Database load slots.
  • DataConnector operator because it is the only consumer operator that can interface with all Teradata PT-supported access modules.
