You can use "SELECT ... INTO variable" to assign query results to variables. But what happens if the SELECT statements return multiple rows? The answer is that you will get a run time error. The following tutorial exercise shows this error condition:
DECLARE
fname VARCHAR2(10);
lname VARCHAR2(10);
BEGIN
SELECT first_name, last_name INTO fname, lname
FROM employees WHERE employee_id = 100;
DBMS_OUTPUT.PUT_LINE('Name = ' || fname || ' ' || lname);
SELECT first_name, last_name INTO fname, lname
FROM employees WHERE employee_id > 100;
DBMS_OUTPUT.PUT_LINE('Name = ' || fname || ' ' || lname);
END;
