Dynamic Index Disable

Question

Hi
Oracle10g R2
Its a part of a long script i want to run without giving any subsequence input.
Query One
select constraint_name from user_constraints where lower(table_name)='my_table' and constraint_type='P'
This query give me the name of index i want to disable
Query Two
alter table my_table disable constraint 'constraint_name'
I wish to join both queries in such a way that result of Query One result will come at the place of Query Two 'constraint_name' and my index get disable
Please advise how?

You need write a PL/SQL Block using dynamic SQL and execute immidiate
the below is the sample script for droping the sequences , edit and make it suitable for your requirements
DECLARE
CURSOR c1 IS
SELECT SEQUENCE_NAME tname from user_sequences;
Begin
FOR emp_rec IN c1 LOOP
dbms_output.put_line(emp_rec.tname);
execute immediate ' drop sequence '||emp_rec.tname;
END LOOP;
EXCEPTION
when others then
dbms_output.put_line('error' || sqlerrm);
END;
