SQL & PL/SQL :: Searching Collection For A Specific Value?

I need to check if a small collection contains a specific value. I know I can use the .exist method to let me know if the nth element exists. But is there a similar syntax for checking if an actual value exists?

So the below collection has 6 values (300,301,310,320,400,410) after the cursor values are fetched. I want to use something similar to the below exists syntax in order to search the collection for a value (rather than position) within an IF statement.

The below code shows the kind of thing I want to do. Currently, unless my test value (310) is in the range 1 to 6 the test will always return FALSE. But is there a similar syntax for testing against the value?

The example I have given is a simplification of what I need. In reality there will be more than one test value... returned by another cursor.

DECLARE
CURSOR c_type_id_usg
IS

[Code]....

-- get the list of sms type id usg values
OPEN c_type_id_usg;
FETCH c_type_id_usg bulk collect into l_type_ids;
CLOSE c_type_id_usg;

-- the above returns value 300,301,310,320,400,410

IF l_type_ids.exists(310)
then
dbms_output.put_line('I have found an entry ');
else
dbms_output.put_line('I have NOT found an entry ' );
end if;
END;
