someone who can help me, disable the constraint of a table in the database using cascade, the problem I have now is that I don't know how I can enable everything using cascade or how I can validate that everything is enabled again
There's no cascade enable foreign key constraints, if that's what you are asking - you'll have to do it manually. It's not that complicated; have a look at the following example.
There are some foreign key constraints in my schema that are disabled:
SQL> select table_name, constraint_name, status
2 from user_constraints where constraint_type = 'R';
TABLE_NAME CONSTRAINT_NAME STATUS
------------------------------ ------------------------------ --------
EMP FK_EMP_DEPT DISABLED
BONUS FK_BON_EMP DISABLED
The following script searches for such a constraints (in USER_CONSTRAINTS) and enables them in a loop, using dynamic SQL (as you can't perform DDL in PL/SQL otherwise):
SQL> declare
2 l_str varchar2(400);
3 begin
4 for cur_r in (select table_name, constraint_name
5 from user_constraints
6 where constraint_type = 'R' and status = 'DISABLED'
7 )
8 loop
9 l_str := 'alter table ' || cur_r.table_name ||
10 ' enable constraint ' || cur_r.constraint_name;
11 dbms_output.put_line(l_str);
12 execute immediate l_str;
13 end loop;
14 end;
15 /
alter table EMP enable constraint FK_EMP_DEPT
alter table BONUS enable constraint FK_BON_EMP
PL/SQL procedure successfully completed.
The result: they are enabled:
SQL> select table_name, constraint_name, status
2 from user_constraints where constraint_type = 'R';
TABLE_NAME CONSTRAINT_NAME STATUS
------------------------------ ------------------------------ --------
EMP FK_EMP_DEPT ENABLED
BONUS FK_BON_EMP ENABLED
