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;
         


        

Answer 1

Is there a way to do:

SELECT * FROM MY_ITEMS 

and then find out how many records are in there?

If you want it to be in this exact order, you can fetch all records on the client and count their number (almost all client libraries provide a function for that).

You can also do:

SELECT  i.*, COUNT(*) OVER ()
FROM    my_items i

, which will return you the count along with each record.
