To run a procedure with cursor output in Oracle, you can follow these steps:

  1. Create a stored procedure that includes a cursor output parameter. Here is an example of a stored procedure with a cursor output parameter:
1
2
3
4
5
CREATE OR REPLACE PROCEDURE getEmployeeCursor(emp_cursor OUT SYS_REFCURSOR) IS
BEGIN
    OPEN emp_cursor FOR
    SELECT * FROM employees;
END;


  1. Call the procedure and receive the cursor output. You can do this using a PL/SQL block or from another programming language such as Java or Python. Here is an example of how to call the getEmployeeCursor procedure from PL/SQL:
 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
15
DECLARE
    emp_cursor SYS_REFCURSOR;
BEGIN
    getEmployeeCursor(emp_cursor);

    -- Fetch and process the results from the cursor
    LOOP
        FETCH emp_cursor INTO emp_id, emp_name, emp_salary;
        EXIT WHEN emp_cursor%NOTFOUND;

        DBMS_OUTPUT.PUT_LINE('Employee ID: ' || emp_id || ' | Employee Name: ' || emp_name || ' | Employee Salary: ' || emp_salary);
    END LOOP;

    CLOSE emp_cursor;
END;


  1. Execute the PL/SQL block containing the procedure call. This will run the stored procedure and fetch the cursor output.


By following these steps, you can run a procedure with cursor output in Oracle and retrieve the results for further processing.
