Review PL/SQL Code
First, examine your existing PL/SQL code. Identify procedures, functions, variables, and any specific Oracle SQL constructs used.
Example PL/SQL Code:
CREATE OR REPLACE FUNCTION get_employee_name(emp_id IN NUMBER) RETURN VARCHAR2 IS
emp_name VARCHAR2(100);
BEGIN
SELECT first_name INTO emp_name FROM employees WHERE employee_id = emp_id;
RETURN emp_name;
END;
