Sample Script

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

PTS00022: Extracting Data from a Teradata Database Staging Table and Loading It into a Production Table.

Rationale

This job uses:

  • DDL operator because it can DROP work tables and CREATE new target tables prior to loading.
  • Export operator because it can extract large amounts of data from a Teradata Database table at high speed.
  • Note: The SQL operator extracts data more slowly than the Export operator. However, the SQL Selector operator can be used if the Teradata Database is short on load slots, because the SQL Selector operator does not use Teradata Database load slots.

  • Use Load operator because it can load large amounts of data into an empty Teradata Database table at high speed.
