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?
