I have a SQL table that looks like this:
id | value
-----------------------
1 | 5
2 | 5
3 | 6
I want to count the value of every rows.
In this example the output should be 16.
What query should I use to count the total value of the rows?
You can learn more about COUNT() Function there.

Alright, so I have a table of persons and each person belongs to a couple. I need to run a query that gets only the older member of each couple. Here is my schema:
id BIGINT
name VARCHAR(32)
couple_id VARCHAR(255)
birthdate TIMESTAMP
And the query I'm working on:
SELECT * FROM person
GROUP BY couple_id
HAVING birthdate > ???
The couple_id is a randomized string. Currently the output looks like this:
1 John AAA 1985/12/04
2 Jane AAA 1984/01/02
3 Christopher BBB 1991/07/07
4 Christina BBB 1992/08/20
5 Alex CCC 1995/02/07
6 Alexandra CCC 1996/11/12
I need a query that returns the rows John, Christina, and Alexandra.
One way to do it is using a derived table.
SELECT p1.*
FROM person p1
join (select couple_id, max(birthdate) as mxbrthdt
from person group by couple_id) p2
on p2.couple_id = p1.couple_id and p1.birthdate = p2.mxbrthdt

I am trying to use the stuff function in MS SQL to stuff certain info. Here is the example:
Number Value
1 1
2 1
3 1
1 2
2 2
3 2
1 3
2 3
I would like to stuff the column so that only one record will display as following:
Value Number
1 1,2,3
2 1,2,3
3 1,2
Please note that there are a like n-Numbers and n-Values.
You can use GROUP_CONCAT for this. For example:
SELECT `Value`, GROUP_CONCAT(DISTINCT `Number` ORDER BY `Number`)
FROM `yourTable`
GROUP BY `Value`

Ids are the repeated one. Now I want the result like
1 aaa,bbb

How can I do that in Mysql ?
Use GROUP_CONCAT()
select id, group_concat(name) as names
from your_table
group by id
