Get a table with a value as key and a count or sum of another column, only of rows with that value

its_meow :

I'm very new to SQL, so I'm having trouble finding the right tools to do what I need. I have a table that looks like this

+----+--------------------------------------+---------------------+---------------------+------------+---------+
| id | uuid                                 | added               | expires             | multiplier | server  |

A want a query that given a UUID, returns a sum of the multiplier column AND a count of rows, with the key being the server name, like so:

+---------+-------+------+
| server  | count | sum  |
+---------+-------+------+
| default |   17  |  17  |
+---------+-------+------+

This is using the provided table, but if I were to use different values for server, the count and sum would be different.

How could I go about doing this?

tcadidot0 :

Try this then:

SELECT `Server`,COUNT(*),SUM(`multiplayer`) 
FROM `table_name` 
WHERE `UUID`='81d9726a-56d4-4419-9a2a-be1d7f7f7ef1'
GROUP BY `Server`;

*I include WHERE UUID
