The following code should help you.  You have to pass the schema name.
My advice is to take a backup before executing this proceudre.
 

CREATE OR REPLACE PROCEDURE PR_DROP_SEQUENCE_TRIGGER

AS

CURSOR C1 IS

SELECT * FROM ALL_OBJECTS AO

WHERE OBJECT_TYPE 

IN ('SEQUENCE', 'TRIGGER')

AND AO.OWNER = <schemaname>

ORDER BY OBJECT_TYPE;
 
 

BEGIN
 

FOR c1_rec IN C1
 

LOOP

   IF c1_rec.OBJECT_TYPE = 'SEQUENCE' THEN

      EXECUTE IMMEDIATE ' DROP SEQUENCE ' || c1_rec.object_name;

   ELSIF c1_rec.OBJECT_TYPE = 'TRIGGER' THEN

      EXECUTE IMMEDIATE ' DROP TRIGGER ' ||c1_rec.object_name;

   END IF;
 

END LOOP;
 

END;

You can also generate a drop script using:

SELECT 'DROP TRIGGER ' || OWNER || '.' || OBJECT_NAME || ';' FROM ALL_OBJECTS AO
WHERE OBJECT_TYPE = 'TRIGGER' AND OWNER = <schemaname> ORDER BY OBJECT_NAME;

Similarly,
SELECT 'DROP SEQUENCE ' || OWNER || '.' || OBJECT_NAME || ';' FROM ALL_OBJECTS AO
WHERE OBJECT_TYPE = 'SEQUENCE' AND OWNER = <schemaname> ORDER BY OBJECT_NAME;
Here also you have to pass the schema name.
You can redirect output of both SELECT's to an .sql file and run them separately at SQL prompt
sql> connect scott/tiger@testdb
sql> spool <path>\log.txt
sql> @ <path>\drop_triggers.sql
sql> @ <path>\drop_sequences.sql
sql> spool off

As in the post 24065873. Do I need to run that procedure from the super user like 'system'. Or can i execute from the same schema where the triggers, sequences are present since I gave all privileges with admin option to that particular schema. Please advise

As in the post 24065873 when I try to run from same schema it did not drop the triggers, sequences. In 'system' user  when i compile the procedure it says compiled. But I could not find it under procedures to run or execute. Please advise.

In Cursor SELECT instead of SELECT *, use OBJECT_NAME, OBJECT_TYPE. You need to create the procedure in a user i.e. schema instead of connecting using system and creating it as it is i.e.
CREATE OR REPLACE PROCEDURE SCHEMA_NAME.PR_DROP_SEQUENCE_TRIGGER

Go through following references for more details:

Also, as one more/last option, check the syntax for CREATE OR REPLACE PROCEDURE from ajexpert. I am not doubting it but just in case there is some slip.

Let say you want to drop the triggers and sequences for schema 'GUDII9' then
SQL> conn system/manager
SQL> spool drop_trig.sql
SELECT 'DROP TRIGGER ' || OWNER || '.' || OBJECT_NAME || ';' FROM DBA_OBJECTS
WHERE OBJECT_TYPE = 'TRIGGER' AND OWNER = 'GUDII9' ;
SQL> spool off;
SQL> @drop_trig.sql
same is the case for sequence drop.

SQL> conn system/manager
SQL> spool drop_seq.sql
SELECT 'DROP SEQUENCE  ' || OWNER || '.' || OBJECT_NAME || ';' FROM DBA_OBJECTS
WHERE OBJECT_TYPE = 'SEQUENCE' AND OWNER = 'GUDII9' ;
SQL> spool off;
SQL> @drop_seq.sql
