SQL & PL/SQL :: Insert Select Statement Limit Inserts?

this is my problem,

insert into t1
select *
from t2
where condition;

Select * from t2 where condition retrieves in example 1000000 records but I only need to insert into t1 the first 100 records.

Is there anyway to abort/limit the insert into t1 to 100 records?

This can´t be used because only applies the condition to the first 100 rows of t2 and it's not valid.

insert into t1
select *
from t2
where condition
where rowcount<100;
