Hi,
>>Will they be enabled after running the script?
Well, of course they need to be re-enabled ... don't you think?
SQL> create table a (id number primary key);
Table created.
SQL> create table b (id number constraint fk_b_a references a);
Table created.
SQL> select constraint_name,status from user_constraints where table_name='B';
CONSTRAINT_NAME                STATUS
FK_B_A                         ENABLED
SQL> truncate table a;
truncate table a
ERROR at line 1:
ORA-02266: unique/primary keys in table referenced by enabled foreign keys
SQL> alter table b disable constraint fk_b_a;
Table altered.
SQL> truncate table a;
Table truncated.
SQL> select constraint_name,status from user_constraints where table_name='B';
CONSTRAINT_NAME                STATUS
FK_B_A                         DISABLED
SQL> alter table b enable constraint fk_b_a;
Table altered.
SQL> select constraint_name,status from user_constraints where table_name='B';
CONSTRAINT_NAME                STATUS
FK_B_A                         ENABLEDCheers
