Trying to print via a table of records - sql

Question

I'm trying to print using a table of records. The original table looks as follows:
CREATE TABLE dept1
( DEPTNO NUMBER(3) PRIMARY KEY,
DNAME VARCHAR2(20),
LOC VARCHAR2(20)
);
Dept = {(10, 'ACCOUNTING', 'NEW YORK'),
(20, 'RESEARCH', 'DALLAS'),
(30, 'SALES', 'CHICAGO'),
(40, 'OPERATIONS', 'DALLAS'),
(50, 'MARKETING', 'BOSTON')}
What I think I'm doing with this code is creating a procedure print_deptlist that will print all the records from the record deptlist that I created: We're required to use that method
CREATE OR REPLACE PROCEDURE print_deptlist IS
deptlist dept1%rowtype;
Begin
Select * into deptlist from dept1;
DBMS_OUTPUT.PUT_LINE(DEPTLIST.deptno || ',' || deptlist.dname || ',' || deptlist.loc);
end;
/
See above...
I'm expecting results that looks lists the column names with the records below:

You can use such a loop statement through
BULK COLLECT which is SELECT statements that retrieve multiple rows with a single fetch, also improving the speed of data retrieval
SQL> SET SERVEROUTPUT ON
SQL> CREATE OR REPLACE PROCEDURE print_deptlist IS
TYPE tab_dept IS TABLE OF dept1%rowtype;
deptlist tab_dept;
BEGIN
SELECT * BULK COLLECT INTO deptlist FROM dept1;
FOR i IN 1..deptlist.count
LOOP
dbms_output.put_line(deptlist(i).deptno || ',' || deptlist(i).dname
|| ',' || deptlist(i).loc);
END LOOP;
END;
