CREATE OR REPLACE FUNCTION gen_email_name (p_first_name VARCHAR2, p_last_name VARCHAR2, p_id NUMBER) RETURN VARCHAR2 is v_email_name VARCHAR2(19); BEGIN v_email_home := SUBSTR(p_first_name, 1, 1) || SUBSTR(p_last_name, 1, 7) || [email protected] .; UPDATE employees SET email = v_email_name WHERE employee_id = p_id; RETURN v_email_name; END; You run this SELECT statement: SELECT first_name, last_name gen_email_name(first_name, last_name, 108) EMAIL FROM employees;
