MySQL: Get total in last row of MySql result

Question

For example I have a table like this:

product | quantity | something
-------------------------------
 abc    |   5      |  2
 xzy    |   5      |  2
 asd             


        

Answer 1

it's not the best way to solve this but should do the trick

select product, quantity, something from tableName
union 
select 'sum', sum(quantity), sum(something) from tableName
