Constraints Problem in DOP table - Help

Question

Sir,
I need to import a new table dump (Status.dmp) to USER1's schema.
USER1 is already having STATUS table (with STATUS_ID column is PRIMARY
KEY.)
I tried to drop table STATUS.
USER1> drop table status;
drop table status
ERROR at line 1:
ORA-02449: unique/primary keys in table referenced by foreign keys
Please clarify my doubts:-
1. How to find the FOREIGN KEY constraints related with STATUS.STAUS_ID.
2. What all steps I have to follow to drop this table.
I did the following steps:-
1. Disabled PRIMARY KEY constraint of SATUS table.
2. Tried to drop the table
drop table status
ERROR at line 1:
ORA-02449: unique/primary keys in table referenced by foreign keys
1. Enabled PRIMARY KEY constraint of SATUS table.
2. Disable all FOREIGN KEY constraints in USER1's schema
(By looking into USER_CONSTRAINTS.CONSTRAINT_TYPE='R'
3. Tried to drop the table
drop table status
ERROR at line 1:
ORA-02449: unique/primary keys in table referenced by foreign keys
1.Disable all FOREIGN KEY constraints in USER1's schema
(By looking into USER_CONSTRAINTS.CONSTRAINT_TYPE='R'
2. Dleted all the rows in STAUS Table.
3. Tried to drop the table
drop table status
ERROR at line 1:
ORA-02449: unique/primary keys in table referenced by foreign keys
4. Imported the dump file with IGNORE=Y
5. Impor wirk fine.
Enabled all disabled constrains.
regards,
Mathew

Answer 1

Will it disable the constraints of child table?SQL> create table one(cd number constraint one_pk primary key, nm varchar2(10));
Table created.
SQL> create table two(cd1 number,nm1 varchar2(10), constraint two_ref foreign key (cd1) references one(cd));
Table created.
SQL> select CONSTRAINT_NAME,CONSTRAINT_TYPE,TABLE_NAME,SEARCH_CONDITION from user_constraints where table_name in ('ONE','TWO');
CONSTRAINT_NAME C TABLE_NAME SEARCH_CONDITION
ONE_PK P ONE
TWO_REF R TWO
SQL> drop table one cascade constraints;
Table dropped.
SQL> select CONSTRAINT_NAME,CONSTRAINT_TYPE,TABLE_NAME,SEARCH_CONDITION from user_constraints where table_name in ('ONE','TWO');
no rows selected
