⟩ How To Assign Query Results to Variables?
If you want to assign results from SELECT statements to variables, you can use the INTO clause, which an extension of SELECT statements for PL/SQL. The sample code below shows some good example on INTO clause:
DECLARE
total NUMBER;
now DATE;
fname VARCHAR2(10);
lname VARCHAR2(10);
BEGIN
SELECT COUNT(*) INTO total FROM employees;
DBMS_OUTPUT.PUT_LINE('Count = ' || TO_CHAR(total));
SELECT SYSDATE INTO now FROM DUAL;
DBMS_OUTPUT.PUT_LINE('Now = ' || TO_CHAR(now, 'SSSSS'));
SELECT first_name, last_name INTO fname, lname
FROM employees
WHERE employee_id = 100;
DBMS_OUTPUT.PUT_LINE('Name = ' || fname || ' ' || lname);
END;

Count = 107
