Oracle Warehouse Builder (OWB) New Feature - ORACLE_DATAPUMP Access Driver in External Table (Doc ID 1347967.1)

Last updated on OCTOBER 24, 2023

Applies to:

Oracle Warehouse Builder - Version and later
Information in this document applies to any platform.


This document describes the new OWB feature for External Tables: the use of the ORACLE_DATAPUMP Access Driver.

Oracle Database provides two Access Drivers for External Tables. The default Access Driver is ORACLE_LOADER, which allows the reading of data from external files using the Oracle loader technology. The ORACLE_LOADER Access Driver provides data mapping capabilities which are a subset of the control file syntax of SQL*Loader utility. The second Access Driver, ORACLE_DATAPUMP, lets you unload data — that is, read data from the database and insert it into an external table, represented by one or more external files — and then reload it into an Oracle Database.

In Oracle Warehouse Builder, the use of the ORACLE_LOADER Access Driver in External Tables is already supported since release 10.2.  OWB now supports the use of the ORACLE_DATAPUMP access driver in External Tables.
