SELECT statement inner join - mysql

Question

I'm trying to find out if I can make one query to out of three I have now.
$sql = "SELECT *
FROM joblist WHERE customer = :customer"; // this is a bindParam
$sql_val = "SELECT a.customer, SUM(a.value) AS tvalue
FROM joblist AS a
INNER JOIN joblist AS b
ON a.customer = b.customer
GROUP BY a.customer";
$sql_bal = "SELECT *
FROM (SELECT SUM(balance) AS tbalance
FROM joblist GROUP BY customer) AS total_balance
WHERE tbalance = :tbalance";
The table that I am using is customer and following is are the columns.
ID - work_order - customer - description - value - balance - status - notes
I'm using php PDO and HTMl of course.
Basically, I have a search function used to query a company. The result are displayed, but I need the totals for the value and balance columns. The only thing that really works is pulling in the data from the table. I've had no success at getting the totals for value and balance.

May not understand your question well so I'll make some guess:
SELECT
t1.*,
t2.tvalue,
t3.tbalance
FROM
(SELECT
*
FROM
joblist
WHERE customer = :customer) t1
JOIN
(SELECT
a.customer,
SUM(a.value) AS tvalue
FROM
joblist AS a
GROUP BY a.customer) t2
ON t1.customer = t2.customer
JOIN
(SELECT
b.customer,
SUM(b.balance) AS tbalance
FROM
joblist AS b
GROUP BY b.customer
HAVING tbalance = :tbalance) t3
ON t3.customer = t1.customer;
