Displaying data from different tables and displaying them In details with summary - sql

Question

I am very beginner and I am just learning by myself, so please excuse if I can't even express what I want to say in Programmer way!
I am trying to develop simple business application that can do this:
Register Employee or Customer.
Can store expenses or money that employee can take in advance before salary payment (This can be done several times, or it may be
zero)
Can store payments (Salary given to the employee) - It can be also done several times
It can calculate all expenses, calculate all payments, then find their difference, hence will be paid the remaining of the balance!
CREATE TABLE Customer
( CustomerID INT IDENTITY (1000,1)
,FirstName VARCHAR(40)
,RegDate DATETIME DEFAULT GETDATE()
,Phone VARCHAR(10)
);
CREATE TABLE Expense
( ExpenseID INT IDENTITY (1000,1)
,CustomerID INT NOT NULL
,ExpDate DATETIME DEFAULT GETDATE()
,Amount MONEY
,Comment VARCHAR (100)
);
CREATE TABLE TblLoad
( LoadID INT IDENTITY (1000,1) --PRIMARY KEY
,CustomerID INT NOT NULL
,DepDate DATETIME DEFAULT GETDATE()
,Amount MONEY
,FromTo VARCHAR (100)
);
select Customer.CustomerID, Customer.FirstName, Expense.Amount As ExpenseAmount from Customer inner join
Expense on Customer.CustomerID = Expense.CustomerID
WHERE Customer.CustomerID = 1000
select Customer.CustomerID, Customer.FirstName, TblLoad.Amount As LoadAmount from Customer inner join
TblLoad on Customer.CustomerID = TblLoad.CustomerID
WHERE Customer.CustomerID = 1000
SELECT Customer.CustomerID, Customer.FirstName, e.SE as AmountExp , l.SL as AmountLoad , (l.SL - e.SE) as FinalPay
FROM Customer
INNER JOIN (SELECT CustomerID, SUM(Amount) AS SE FROM Expense GROUP BY CustomerID) E
ON Customer.CustomerID = e.CustomerID
INNER JOIN (SELECT CustomerID, SUM(Amount) AS SL FROM TblLoad GROUP BY CustomerID) L
ON Customer.CustomerID = l.CustomerID
WHERE Customer.CustomerID = 1000
Attached are pictures of what I expected, and what I was willing

Firstly congrats on getting as far as you have. The bad news is that t-sql is not a reporting tool - you need to look elsewhere if you want pretty output (SSRS,Crystal reports, excel etc,etc) to get anywhere near to your required ouput in t-sql you need to get a bit creative for example:-
/*
drop table customer
drop table expense
drop table TblLoad
CREATE TABLE Customer
( CustomerID INT --IDENTITY (1000,1)
,FirstName VARCHAR(40)
,RegDate DATETIME --DEFAULT GETDATE()
,Phone VARCHAR(10)
);
INSERT INTO CUSTOMER
( CustomerID
,FirstName
,RegDate
,Phone )
VALUES
(1001,'Emp1',cast('2015/10/20 00:00:00.000' as datetime), null),
(1002,'Emp2',cast('2015/10/22 00:00:00.000' as datetime), null),
(1003,'Emp3',cast('2015/10/25 00:00:00.000' as datetime), null)
CREATE TABLE Expense
( ExpenseID INT --IDENTITY (1000,1)
,CustomerID INT NOT NULL
,ExpDate DATETIME DEFAULT GETDATE()
,Amount MONEY
,Comment VARCHAR (100)
);
truncate table expense
insert into expense
( ExpenseID
,CustomerID
,ExpDate
,Amount
--,Comment
)
Values
(1001,1001,cast('2015/10/21' as datetime),100),
