About sql server2008 running total - sql-server

Question

I have a table , the table structure is:
TransactionRecordID State TransactionMoney CreateTime
1 1 200 2014/6/19
2 0 100 2014/6/12
3 1 50 2014/3/17
4 1 400 2014/2/23
......
I want to get the result:
TransactionRecordID State TransactionMoney CreateTime TotalMoney
1 1 200 2014/6/19 650
2 0 100 2014/6/12 450
3 1 50 2014/3/17 450
4 1 400 2014/2/23 400
If current record field state=1,I would like to get sum TransactionMoney after current
record add current TransactionMoney , else get sum TransactionMoney after current record
Sorry for my english!

Answer 1

SQL Server 2012 makes this a lot simpler using SUM() OVER (ORDER BY ...), but in SQL Server 2008 you can use a LEFT JOIN for the same effect;
SELECT a.TransactionRecordID, a.State, a.TransactionMoney, a.CreateTime,
COALESCE(SUM(b.TransactionMoney), 0) TotalMoney
FROM transactions a
LEFT JOIN transactions b ON a.CreateTime >= b.CreateTime AND b.state = 1
GROUP BY a.TransactionRecordID, a.State, a.TransactionMoney, a.CreateTime
ORDER BY a.TransactionRecordID;
An SQLfiddle to test with.

Here is a CTE Example for Northwind. it might give you some alternate ideas.
Use Northwind
GO
declare #CustomerID varchar(6)
declare #BeginDate datetime
declare #EndDate datetime
select #CustomerID = (select top 1 CustomerID from dbo.Orders )
select #BeginDate = '01/01/1900'
select #EndDate = '12/31/2010'
;
WITH
MyCTE /* http://technet.microsoft.com/en-us/library/ms175972.aspx */
( ShipName,ShipAddress,ShipCity,ShipRegion,ShipPostalCode,ShipCountry,CustomerID,CustomerName,[Address],
City,Region,PostalCode,Country,Salesperson,OrderID,OrderDate,RequiredDate,ShippedDate,ShipperName,
ProductID,ProductName,UnitPrice,Quantity,Discount,ExtendedPrice,Freight,ROWID) AS
(
SELECT
ShipName ,ShipAddress,ShipCity,ShipRegion,ShipPostalCode,ShipCountry,CustomerID,CustomerName,[Address]
,City ,Region,PostalCode,Country,Salesperson,OrderID,OrderDate,RequiredDate,ShippedDate,ShipperName
,ProductID ,ProductName,UnitPrice,Quantity,Discount,ExtendedPrice,Freight
, ROW_NUMBER() OVER ( ORDER BY OrderDate , ProductName ASC ) as ROWID
FROM
dbo.Invoices inv /* “Invoices” is a VIEW, FYI */
where
inv.CustomerID = #CustomerID and (inv.OrderDate between #BeginDate and #EndDate)
)
SELECT
/*
ShipName,ShipAddress,ShipCity,ShipRegion,ShipPostalCode,ShipCountry,CustomerID,CustomerName,[Address],
City,Region,PostalCode,Country,Salesperson,OrderID,OrderDate,RequiredDate,ShippedDate,ShipperName,
ProductID,ProductName,UnitPrice,Quantity,Discount,ExtendedPrice,Freight,
*/
/*trim the list down a little for the final output */
CustomerID ,Salesperson,OrderID,OrderDate,ProductName,UnitPrice,Quantity,Discount,ExtendedPrice,Freight,(ExtendedPrice + Freight) as ComputedTotal
/*The below line is the “trick”. I reference the above CTE, but only get data that is less than or equal to the row that I am on (outerAlias.ROWID)*/
, (Select SUM (ExtendedPrice + Freight) from MyCTE innerAlias where innerAlias.ROWID <= outerAlias.ROWID ) as RunningTotal
, ROWID as ROWID_SHOWN_FOR_KICKS , OrderDate as OrderDateASecondTimeForConvenience
FROM
MyCTE outerAlias
/*Two Order By Options*/
ORDER BY outerAlias.OrderDate , ProductName
/* << Whatever the ORDER BY is here, should match the “ROW_NUMBER() OVER ( ORDER BY ________ ASC )” statement inside the CTE */
/*ORDER BY outerAlias.ROWID */ /* << Or, to keep is more “trim”, ORDER BY the ROWID, which will of course be the same as the “ROW_NUMBER() OVER ( ORDER BY” inside the CTE */
