I read the question as you want to get all rows and a sum of those rows in one query.

You could do this all in one hit using WITH ROLLUP, e.g.

select *,sum(v_view) as total from videos 
where v_uid=45 
group by vid with rollup;

Bit hacky, as we don't really need the group by (which is why I'm grouping on the row id vid). What you'll end up with all the individual rows, and a final row with the total sum in it (it will have a NULL vid too, which might help identify it)

If you just want a sum of the views, then you can execute something much simpler

select sum(v_view) as total from videos where v_uid=45;
