How the REPLACE Option Works During an Import When There is a Foreign Key on the Imported Parent Table

(Doc ID 1940883.1)

Last updated on NOVEMBER 19, 2014

Applies to:

Oracle Database - Enterprise Edition - Version 11.2.0.4 and later
Information in this document applies to any platform.

Goal

When a table is truncated, it complains a FK in child table exists and the truncate is aborted.
However, it succeeds doing an impdp with  table_exists_action = "REPLACE" without any constraints error.
According to the documentation, IMPDP with replace option drops and recreates the table.
So how does "impdp with replace" work?
