PL/SQL Cursor Exercises: FETCH multiple records and more than one columns from different tables

PL/SQL Cursor: Exercise-18 with Solution

Write a program in PL/SQL to FETCH multiple records and more than one columns from different tables.

Below example we are trying to fetch department names and employee names.

Sample Solution:

PL/SQL Code:

DECLARE
    CURSOR cur_emp_name IS
      SELECT first_name,
             last_name,
             department_name
      FROM   employees e,
             departments d
      WHERE  d.department_id = e.department_id;
    v_emp_rec cur_emp_name%ROWTYPE;
BEGIN
    OPEN cur_emp_name;
    LOOP
        FETCH cur_emp_name INTO v_emp_rec;
        exit WHEN cur_emp_name%NOTFOUND;
        dbms_output.Put_line('Name:  '
                             || v_emp_rec.first_name
                             || '  '
                             ||v_emp_rec.last_name
                             || '   ::   department: '
                             || v_emp_rec.department_name);
    END LOOP;
    CLOSE cur_emp_name;
END; 
 /
