Number of rows in Oracle SQL Select?

Question

I need to know how many records were returned in a select in oracle. Currently, I do two queries:

SELECT COUNT(ITEM_ID) FROM MY_ITEMS;

SELECT * FROM MY_ITEMS;

I'm just unsure about the table aliases, I don't remember in Oracle if they require 'AS' or not. But this should work.

select mt.*, c.Cntr
    from MyTable mt
        , (select COUNT(*) as Cntr
               from MyTable
           ) c
