Oracle SQL -- insert multiple rows into a table with one statement?

I'd like to do insert N rows that are all identical, except one of the values is different. Specifically, this is what I am trying:

insert into attribute_list (id,value,name)
values 
(
select (id,'Y','is_leveled') from value_list where val >= 50
);

So for every value that has a val >= 50, I would insert one row into attribute_list. Can this be done with one insert statement or should I just manually generate these inserts in excel?

(note: this is a cooked example simplified to clarify the issue, so no need to attack the needlessness of this specific case)

You need an INSERT from SELECT. To do so you should omit the VALUES and just do:

insert into attribute_list (id,value,name)
select (id,'Y','is_leveled') from value_list where val >= 50;

Here's an example: http://psoug.org/reference/insert.html

That is what FOR loops are for.

DECLARE
   x NUMBER := 100;
BEGIN
   FOR i IN 1..10 LOOP
      IF MOD(i,2) = 0 THEN     -- i is even
         INSERT INTO temp VALUES (i, x, 'i is even');
      ELSE
         INSERT INTO temp VALUES (i, x, 'i is odd');
      END IF;
      x := x + 100;
   END LOOP;
   COMMIT;
END;

You can absolutely do this in a single statement!

Try this:

INSERT INTO attribute_list (id, value, name)
SELECT id, 'Y', 'is_leveled'
FROM value_list WHERE val >= 50

You can do a SELECT ... INTO if you can query the data. Otherwise to create data you'd need to use PL/SQL

If you have the data then try:

select id,'Y','is_leveled'
INTO attribute_list 
from value_list where val >= 50
