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

$q="select sum(quantity), sum(something) from tableName";

Answer 2

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

Answer 3

Try to avoid union query it may increase the execution time in case of joins and case queries. So as @Chris Strickland said, use WITH ROLLUP.

Answer 4

(SELECT product, 
        quantity, 
        something 
 FROM   tablename) 
UNION 
(SELECT "all"          AS product, 
        SUM(quantity)  AS quantity, 
        SUM(something) AS something 
 FROM   tablename) 

This is working query. It will add a fourth row as desired at the end of your result

Answer 5

You can use rollup to generate totals, but you have to change it to an aggregate function, like this:

SELECT product, sum(quantity), sum(something)
FROM tableName
GROUP BY product WITH ROLLUP

Answer 6

You could

SELECT Product, Quantity, Something 
FROM TABLENAME

UNION

SELECT 'ALL', SUM(Quantity),SUM(Something) 
FROM TABLENAME

This would not, however, add a row in your table. Which is probably not a good idea anyways.
