Saving result set in variable using a cursor - sql

Question

I have a problem using Oracle SQL to loop over a result set twice.
The problem
I have a cursor that gets me all foreign keys to a given table name. Using the result form this cursor, I loop through all the constraints and disable them. Then I perform a data import and then I need to loop over the same result set and enable them.
CURSOR c_fkeys_inn(tabellnavn IN VARCHAR2)
IS
SELECT table_name,constraint_name, status
FROM user_constraints
WHERE (r_constraint_name,r_owner) IN
(SELECT constraint_name, owner
FROM user_constraints
WHERE owner ='POP'
AND table_name=upper(tabellnavn)
)
AND STATUS = 'ENABLED';
What I would like to do
My brain jumps directly to a variable. I would like to perform the cursor just once, and then save the result from the cursor to a variable.
Is this possible or are there anything I do to save the result from the cursor and loop twice?

Please try this code. I have sightly modified your code to just display the constraint's table names. You can modify the end part of the plsql according to your requirement. Please comment if you have come across any mistakes or issues, thank you.
CREATE or replace PROCEDURE a_proc(name_table varchar)
AS
CURSOR c_fkeys_inn(tabellnavn IN VARCHAR2)
IS
SELECT table_name,constraint_name, status
FROM user_constraints
WHERE STATUS = 'ENABLED'
AND TABLE_NAME=tabellnavn;
names_t c_fkeys_inn%ROWTYPE;
TYPE c_fkeys IS TABLE OF names_t%TYPE;
fkeys c_fkeys;
BEGIN
OPEN c_fkeys_inn(name_table);
FETCH c_fkeys_inn BULK COLLECT INTO fkeys;
CLOSE c_fkeys_inn;
FOR indx IN 1..fkeys.COUNT LOOP
DBMS_OUTPUT.PUT_LINE(fkeys(indx).table_name);
END LOOP;
END a_proc;
To run the code please run a separate plsql block. Please find a simple and a sample plsql block given below.
begin
a_proc('SUPPLIER');
END;
