import table with dependency


Posted on 16th Feb 2014 07:03 pm by admin

Hi

What is the best way to import table back which has dependency?

SQL> create table test (a number); Table created. SQL> create table test2 (b number); Table created. SQL> alter table test2 add constraint pk_test2 primary key(b); Table altered. SQL> ALTER TABLE test add CONSTRAINT fk_test FOREIGN KEY (a) REFERENCES test2(b); Table altered. exp system/**** file=C:/test2.dmp tables=test2 About to export specified tables via Conventional Path ... . . exporting table TEST2 0 rows exported Export terminated successfully without warnings. Sometime later, I want to import table test2. Inorder to achieve this I need to drop table first and then start import. SQL> drop table test2; drop table test2 * ERROR at line 1: ORA-02449: unique/primary keys in table referenced by foreign keys If I use cascade option, I will lose the foreign key in other table. What should I do in this issue?
