Conditional Predictions On Stock Prices?

Mar 13, 2007

I would like to use analysis services to analyze stock prices.

I want to find conditional probabilities:
P (YpriceChg >= 10% s.t. Ydate between A and B| X Price Chg >= 20%)?

�� Like given a price change of X percent or greater, predict the probability of a price change of Y percent or greater, within a specified time window (like 2 days, 3 months etc.).

I also want to add a support filter, like:

N > 30 cases (i.e., there have been at least 10 instances of a 10% or greater price change, for the chosen time window)

I have a database of prices, monthly, daily, etc. I also have a number of cols that compute statistics such as pChg1M, pChg-1M, vChg1d. Like price chg 1 month forward, price change 1 month backward, volumeChg1d forward. Ideally, I would like to minimize the column flags necessary for the experiment. Can you offer some hints, as far as setting up appropriate columns/flags and choosing a algorithm (maybe decision trees, association rules, or NB)?

Calculate A Range Bar From (stock) Tick Prices?

Dec 30, 2011

Assume you have a table called Tick with 2 columns
(
tickId bigint IDENTITY(1,1)
, price int -- usually money data type, making it int for simplicity
)

I am tasked with creating bars that are 10 units long.

Now the catch is I'm not looking for the tickId where price is >= t1(price) + 10 where t1(price) is the price for the first row where tickId = 1. (it could also be where price <= t1(price) - 10)

Here is sample data:

1, 25
2, 26
3, 23
4, 26
5, 27
6, 30
7, 34
8, 32
9, 30
10, 33

What I am looking for are rows 3 (23) and 7 (34)

Currently I have:

Code:
DECLARE @tickDiff int
SET @tickDiff = 10
DECLARE @r1TickId bigint

[Code].....

This seems to work but it is taking multiple minutes to run for about 50k rows of data (which I created off of the 24 million row table I have just looking at data from today). So it takes ~5 minutes to create the first bar which is not acceptible.

If my logic above seems acceptable are there any indexes you could recommend. Database engine tuning advisor didn't find any.

Convert Tick-by-tick Stock Price Time Series Data Grouped As High, Low, Open And Close Prices

Dec 3, 2006

I am working on a stock price analysis project. Stock prices are stored in SQL Server as tick by tick data (that means in a high frequency) and need to be grouped by minutes in order to display them as as high, low, open and close prices in a candlestick or similar chart.

The fields in the table are:

Time (for every stock price tick)
Price (stock price)
Symbol (of the stock)

A sample time series would look like this:

11:45:01 $22.11 MSFT
11:45:02 $22.10 MSFT
11:45:04 $22.25 MSFT
...
...
...
11:45:58 $22.45 MSFT
11:46:03 $22.22 MSFT
11:46:08 $22.25 MSFT
...
...
...
11:46:59 $22.45 MSFT

The result of the SQL query should be:

Symbol Time Open High Low Close
MSFT 11:45 $22.11 $22.45 $22.10 $22.45
MSFT 11:46 $22.22 $22.45 $22.22 $22.45

This is the SQL statement I came up with but obviously doesn't work:

SELECT DATEPART(Minute,Time), MIN(Price), MAX(Price) FROM dbo.TimeSales WHERE Symbol='MSFT' GROUP BY DATEPART(Minute,Time)

I would appreciate any suggestions.

Thank you!

Newbie, Sage Updating Invoice Prices With Current Prices

Sep 22, 2007

Dear all

I have a company that sells fruit and vegetables to the catering industry.

Association Mining Model Predictions

May 17, 2007

Hi,

I've been playing around with the association mining model in SQL server 2005 and built a market-basket analysis of my data that I'm pretty happy with. The next task for me is figuring out how to run DMX queries against the data that I've just mined, so we may possibly use it in a web based application. This wouldn't necessarily be a difficult problem (and still may not be), but every example I've seen for the Mining Model Prediction Designer uses relational databases and I built my mining model off OLAP. Therefore, my predictable attribute is nested and when relating the mining model structure to the relational database that the cube was built off always gives me an error:

"Errors in the high-level relational engine. The 'CompanyName' column could not be found in the top-level clause of the SHAPE statement."

What I would like to do, and I'm not really even sure how I should structure any of my queries, is feed the model a product and have it return a listing of all the products it predicts. Currently, I've only been able to get the designer mode to process a singleton query, and even that didn't return any useful data. I know that this probably can be done pretty easily so any advice you may be able to offer would be greatly appreciated!!

So you may better understand my question, my association mining structure hierarchy looks as this..

[Model] ProductRecommend

[Case][Key]CustomerList

[Case][Attribute]CompanyName

[NestedTable]Product

[Nested][Key]PRODUCTCLASSID

[Nested][Attribute]PRODUCT

With that in mind, I'm trying to perform a query simliar to this:

SELECT

PredictProbability([ProductRecommend].[Product].[PRODUCTCLASSID]), <---- Throws Error for PredictProbability syntax no matter what I try to get to [PRODUCTCLASSID]

(SELECT [PRODUCT] FROM [ProductRecommend].[Product])

From

[ProductRecommend]

NATURAL PREDICTION JOIN

(SELECT 'test' AS [COMPANYNAME],

(SELECT '1234' AS [PRODUCTCLASSID],

'ProductA' AS [PRODUCT]) AS [Product]) AS t

Thanks again for any help!

Decision Tree Predictions Occuring At Non-leaf Node

May 2, 2007

After having built a decision tree model to predict a boolean output attribute using 64-bit SQL Server 2005 (build 9.0.3054), we have observed that predictions for some cases are being done at non-leaf nodes in the tree.

Specifically, after executing a prediction join which returns:

- CaseTable.CaseID
- MiningModel.OutputAttribute
- PredictProbability(MiningModel.OutputAttribute)
- PredictNodeId(MiningModel.OutputAttribute)

and comparing the values of PredictNodeID(MiningModel.OutputAttribute) with the mining model content column [NODE_UNIQUE_NAME] to determine the actual "rule" used to make the case-level prediction.

We have observed that for a subset of cases, predictions are being made at nodes in the tree that are not leaf nodes. Specifically, predictions are being made at a node that is 3 levels deep. The leaf nodes below this inner-tree node are 2 levels further down the tree.

Also supporting the fact that that predictions are being made at this non-leaf node is that the PredictProbability corresponds exactly with the output attribute distribution at this non-leaf node.

In this particular application, we would have obtained better results if the predictions were made at the leaf-nodes.

A few questions:
1. Why are predictions with decision trees made at non-leaf nodes?
2. Is there a way to "force" predictions to occur at leaf nodes via DMX?

Thanks in advance for any information or advice.

- Paul

Problems With Neural Net Viewer, Lift Chart And Predictions Still Ocurring In SP2

Nov 24, 2006

Greetings,

I have a mining structure that I am using to perform a text-mining
classification task. The mining structure contains three models: a
decision tree, a naive bayes and a neural network.

Both the decision tree and the naive bayes models process without
any problems, but I am having significant difficulties with the neural
network model.

Initially when I processed the model, processing would fail altogether with the following error message:

"Memory error: Allocation failure : Not enough storage is available to process this command"

This was remedied by taking the steps prescribed in
http://support.microsoft.com/kb/917885 (I upgraded to SQL 2005 SP1 and
applied all available hotfixes listed in
http://support.microsoft.com/kb/918222/). This got me to the point
where the model (seemingly) processed correctly after restricting the
MAXIMUM_INPUT_ATTRIBUTES to a relatively low number. So after
processing, I went to try and browse the neural network model and view
the lift chart...

<error>

"Execution of the managed stored procedure GetAttributeScores
failed with the following error: Exception has been thrown by the
target of an invocation.Input string was not in a correct format.."

</error>

(see http://forums.microsoft.com/TechNet/ShowPost.aspx?PostID=935340&SiteID=17)

Also when I would attempt to view the lift chart and the
classification matrix the queries would time out with the following
error message:

<error>

XML for Analysis parser: The XML for Analysis request timed out before it was completed.

Execution of the managed stored procedure
GenerateLiftTableUsingDatasource failed with the following error:
Exception has been thrown by the target of an
invocation.Microsoft::AnalysisServices::AdomdServer::AdomdException.

</error>

Now, my poking around on Technet lead me to believe that this issue
could finally be resolved by uprading to the CTP release of SQL server
2005 SP2. Now I am still encountering problems. When I go to browse the
model in the Neural Network Viewer, I see the correct drop down menus
to select attributes and attribute values in the "Input" and "Output"
panes but I see no data displayed in the "Variables" pane at the
bottom.

Interestingly, while I cannot view the model contents in the
graphical viewer, the mining model contents viewer reveals model
contents that look to be pretty normal for a trained neural network.

Attempts to view the lift chart time out with the error message:

<error>

XML for Analysis parser: The XML for Analysis request timed out before it was completed.

Execution of the managed stored procedure
GenerateLiftTableUsingDatasource failed with the following error:
Exception has been thrown by the target of an
invocation.Microsoft::AnalysisServices::AdomdServer::AdomdException.

</error>

and when I run predictions against the trained NN model in the
"Mining Model Prediction" pane it predicts the same value for every
case in the testing set.

Any thoughts?

SSAS Crashes - Mining Predictions For Large Data Sets

Sep 7, 2006

Hi all,

I am using SSAS 2005. The mining model works fine. But it crashes when I run the 'Mining Model Predictions' against large data sets.

I ran it against 5,000,000 records and it went fine.

But exactly same model failed for 5,100,000 records and beyound.

The message is 'Query Execution Failed' and then Visual Studio crashes.

Pl. let me know if anybody has the same experience or knows the solution.

Thanks,

Summing Prices Day By Day

Oct 23, 2013

Let suppose that we have a table which look like this

BillDate Price
01.01.2013 2.00
01.01.2013 1.00
02.01.2013 3.00
02.01.2013 2.00
03.01.2013 1.00

I would like to sum a prices day by day and output to be like this

BillDate SumDaylyPrice
01.01.2013 3.00
02.01.2013 5.00
03.01.2013 1.00

To point I’ve reached myself is a query:

SELECT BillDate, (SELECT SUM( Price) FROM Table1 ) AS SumDaylyPrice
FROM Table1
WHERE BillDate BETWEEN
(SELECT Min(BillDate) FROM Table1)
AND
(SELECT Max(BillDate) FROM Table1)
GROUP BY BillDate

but this doesn’t work- summing everityng

I don’t know how to indicate in first row of query
SELECT BillDate, (SELECT SUM( Price) FROM Table1 WHERE DATE = ????) AS SumPrice
a WHERE clause for every day separately.

How To Get Prices From Table Where Date Not Exists

Feb 17, 2013

I have 2 test tables one for stock and one for prices.

I need to select all the rows from Stock but also the price on the stock but the price table doesn't always have the date, so I can not do stock date = price date.

What it needs to do is if the Stoc Date isn't in the price table use the price before... this would also have to be able to run on my rows...

-- Create Test Table (not sure if dates USA or UK format on your machine...

CREATE TABLE [dbo].[TheStockLedger](
[EntryID] [int] NULL,
[TheDate] [datetime] NULL,
[StoreCode] [nvarchar](50) NULL,
[Item] [nvarchar](50) NULL,

Historical Prices With Data Gaps

Apr 24, 2008

Hi,

I have a SQL2005 db for tracking the prices of products at multiple retailers. The basic structure is, 'products' table lists individual products, 'retailer_products' table lists current prices of the products at multiple retailers, and 'price_history' table records when the price of a product changes at any retailer. The prices are checked from each retailer daily, but a row is added to the 'price_history' only when the price at the retailer changes.

Database create script:
http://www.boltfile.com/directdownload/db_create_script.sql

Full database backup:
http://www.boltfile.com/directdownload/database.bak

Database diagram:
http://www.boltfile.com/directdownload/diagram_0.pdf

I have the following query to retrieve the price history of a given product at multiple retailers:

SELECT
price_history.datetimeofchange, retailer.name, price_history.price
FROM
product, retailer, retailer_product, price_history
WHERE
product.id = 'b486ed47-4de4-417d-b77b-89819bc728cd'
AND
retailer_product.retailerid = retailer.id
AND
retailer_product.associatedproductid = product.id
AND
price_history.retailer_productid = retailer_product.id

This gives the following results:

2008-03-08 Example Retailer 22.3
2008-03-28 Example Retailer 11.8
2008-03-30 Example Retailer 22.1
2008-04-01 Example Retailer 11.43
2008-04-03 Example Retailer 11.4

The question(s) I have are how can I:

1 - Get the price of a product at a given retailer at a given date/time
For example, get the price of the product at Retailer 2 on 03/28/2008. Table only contains data for Retailer 1 for this date, the behaviour I want is when there is no data available for the query to find the last data at which there was data from that retailer, and use the price from that point - i.e. so for this example the query should result in 2.3 as the price, given that was the last recorded price change from that retailer (03/08/2008).

2 - Get the average price of a product at a given retailer at a given date/time
In this case we would need to perform (1) across all retailers, then average the results

I'd really appretiate anyone's help on this :)

many thanks in advance,

dg

Conditional Subscription / Conditional Execution Of Report

Mar 7, 2008

Hello everyone,

Is there a way in order to execute a subscribed report based on a certain criteria?

For example, let's say send a report to users when data exist on the report else if no data is returned by the query
executed by the report then it will not send the report to users.

My current situation here is that users tend to say that this should not happen, since no pertinent information is contained in the report, why would they receive email with blank data in it.

Any help or suggestions will be much appreciated.

Thanks,

Complex Stock Query

Jun 17, 2008

Well probably not that complex for some of you out there!

I need to work out the amount of stock which was sold between @datefrom and @dateto and how much we currently have on hand (to work out if we are over ordering etc). That's the pretty easy part but I also need to include a column which works out how many items have been sold 3 months prior to @datefrom (from invoiceline). The proc I have so far works out the items sold between 2 dates so basically what I need is another column which is the amount sold (QtySold) in the 3 months prior to datefrom

This is the basic part I have so far:

ALTER PROCEDURE [dbo].[rptstockholdinglevel]
-- Add the parameters for the stored procedure here
@datefrom datetime,
@dateto datetime,
@periodname varchar(50),
@percentage int
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;

-- Insert statements for procedure here
SELECT
products.productname,
@periodname AS periodname,
isnull(SUM(invoiceline.qty),0) AS QtySold,
products.qtyonhand AS OnHand,
nominals.nominalname,
productcategories.categoryname,
productmanufacturers.manufacturername
FROM
productmanufacturers RIGHT OUTER JOIN
invoices INNER JOIN
invoiceline ON invoices.invoiceid = invoiceline.invoiceid RIGHT OUTER JOIN
products ON invoiceline.productid = products.productid ON productmanufacturers.manufacturerid = products.manufacturerid LEFT OUTER JOIN
nominals INNER JOIN
productcategories ON nominals.nominalid = productcategories.salesnominal ON products.categoryid = productcategories.productcategoryid
WHERE
(invoices.invoicedate BETWEEN @datefrom AND @dateto)
OR
(invoices.invoicedate is null)
GROUP BY
products.productname,
products.qtyonhand,
productcategories.categoryname,
nominals.nominalname,
productmanufacturers.manufacturername
HAVING (SUM(isnull(invoiceline.qty,0)) < products.qtyonhand)
ORDER BY
nominals.nominalname,
productcategories.categoryname,
productmanufacturers.manufacturername
END

I'd be really grateful for any pointers as I'm just going round in circles on this one.

Thanks in advance as usual all :)

Stephen.

Inventory Stock, Triggers Vs Views/SP

Jan 22, 2007

Hello..

I am designing a Database Application that covers Inventory System. And I am now in a dilemma of chosing which design to track Inventory stock better, in performance, reliability, and error free?

1st Design

PRODUCT TABLE
ItemID
ItemName
Price
QtyOnHand
..and other unique info of the product..

SALES TABLE
SalesID
Date
...etc...

SALESDETAIL TABLE
SalesID
ItemID
QtySold
Price

PURCHASE TABLE
PurchaseID
Date
...etc...

PURCHASEDETAIL TABLE
PurchaseID
ItemID
QtyPurchase
Price
...etc...

and similar design with SALESRETURN+DETAIL, PURCHASERETURN+DETAIL, ADJUSTMENT+DETAIL

Tracking Inventory stock is done by using (update, insert and delete) triggers in each of the DETAILS to update the QtyOnHand in the PRODUCT TABLE

2nd Design

PRODUCT TABLE
ItemID
ItemName
Price
...etc...

INVENTORY TABLE
ItemID
QtyBegin
...etc...

SALES TABLE
SalesID
Date
...etc...

SALESDETAIL TABLE
SalesID
ItemID
QtySold
Price
...etc...

and similar design with PURCHASE+DETAIL, SALESRETURN+DETAIL, PURCHASERETURN+DETAIL, ADJUSTMENT+DETAIL

The later design does not hold QtyOnHand, but only save QtyBegin instead. To get the QtyOnHand, it uses views/stored procedure with Union Query, so it looks like this:

QtyOnHand = QtyBegin + Sum(QtySold) + Sum(QtyPurchase) + Sum(QtySalesReturn) + ........

And at the end of a accounting period, the calculation of the QtyOnHand will be the QtyBegin of the next accounting period.

According to you guys, which way is better in PERFORMANCE, RELIABILITY, ERROR FREE, and why? What are the pros and cons of these two?

Thanks a lot.

Transact SQL :: How To Calculate A Running Stock Value

Oct 8, 2015

I have the following store procedure :

SELECT APHIST.ReturnDate AS ATDATE
,API_HIST.[ActionPlanItemID]
,API_HIST.[ActionPlanID]
,PIT.[ProductItemID]
,PIT.ProductItemCode
,PIT.Name,

[code]....

What I am trying to get is a RunningStock level column which is able to display stock level as describe below :

If ItemStatus value is 0, that means that the item has been taken out from stock.

So based on that the first row running Stock level is calclulated as

(ProductQuantity * ItemUnitWeight)-ItemQuantity=9...

For the second record, ItemsStatus=1 which means the item return to stock, at the time the running stock value calculation should be the previous row Running Stok value (=9 ) +(ItemQuantity*ItemUnitWeight)When the ItemStatus=2, that means the item is definitely out and will be never back to current stock. Is there a way to get that calculation field ?

I have stock data in 1 min intervals and would like to convert it into other timeframes (e.g., 10 min, daily, monthly).

Here's is some sample data and my final goal:

[DateTime] [Open] [High] [Low] [Close] [Volume]
10-Feb-05 12:10:00 3.88 3.88 3.87 3.87 10
10-Feb-05 12:11:00 3.87 3.87 3.87 3.87 2
10-Feb-05 12:12:00 3.86 3.86 3.86 3.86 1
10-Feb-05 12:13:00 3.85 3.87 3.84 3.85 23
10-Feb-05 12:14:00 3.85 3.85 3.85 3.85 6
10-Feb-05 12:15:00 3.86 3.86 3.86 3.86 1
10-Feb-05 12:16:00 3.85 3.85 3.85 3.85 1
10-Feb-05 12:18:00 3.85 3.85 3.85 3.85 3
10-Feb-05 12:19:00 3.85 3.85 3.85 3.85 3

[DateTime] [Open] [High] [Low] [Close] [Volume]
10-Feb-05 12:10:00 3.88 3.88 3.84 3.85 50 *

Oct 4, 2007

hi allin the sample of sqlserver2005(notification service(stock))this is code sample in :appADF.xml(stock) -------------------------- -- Update value in the chronicle if event price greater than value in the chronicle UPDATE StockEventsChron SET StockPrice = E.StockPrice FROM StockEvents E, StockEventsChron C WHERE E.StockSymbol = C.StockSymbol AND E.StockPrice > C.StockPrice.for scenario: + the first SubscriberId(Stephanie) set :StockTriggerValue=20, and stockPrice changge =50 -> one notification for Stephanie and in the table StockEventsChron the value field :StockPrice = 50, + the next : stockPrice changge = 25. the field value StockPrice of table StockEventsChron is still 50 + then second SubscriberId(Scott) set StockTriggerValue=30 but---------------- Insert Into StockNotifications ( S.SubscriberId, S.DeviceName, S.SubscriberLocale, E.StockSymbol, E.StockPrice ) SELECT S.SubscriberId, S.DeviceName, S.SubscriberLocale, E.StockSymbol, E.StockPrice FROM StockSubscriptions S JOIN StockEvents E ON S.StockSymbol = E.StockSymbol LEFT OUTER JOIN StockEventsChron c ON S.StockSymbol = c.StockSymbol WHERE S.StockTriggerValue <= E.StockPrice AND (S.StockTriggerValue > c.StockPrice OR c.StockPrice IS NULL) here :StockTriggerValue=30 < c.StockPrice=50 so no notification for Scott, why ?can anyone help me?

Urgent Stock Options/org Chart Query

Jan 9, 2001

Okay, here's an algorithm question for you TSQL gurus out there...

Due to circumstances beyond our control, our group has been tasked with a massive project and a very short timeline. And of course, timely completion is needed because our STOCK OPTIONS grants depend on this! And of course board meetings are always scheduled sooner than you expect.

Here's one of the killer questions we're trying to solve...

Given a table of employee ID's, associated supervisor ID's, and the amount of stock options given, how would you write a stored procedure to return, for any branch of the organizational tree, the sum of all the stock options in a particular branch?

Example:

EMPID SUPERVISORID STOCKOPTIONS
1 2 100
2 30 500
3 2 150
30 50 1000
50 60 5000

What we need is something like : "sp_StockOptionsPerDepartment @SUPERVISORID=30"
with a result : "1750".

Basically we're building an organizational chart of our company from this table, on the fly, and also counting up for certain branches of the org chart, the total stock options.

If a manager has two managers under him, and each sub-manager has three employees, then we want to know the total stock options that all 3+3+2+1 = 9 people possess. Basically it's the total pool of stock options for a department, or work group, or division, etc.

Got this to work for a small set of employees, but when we begin to scale up to entire departments, the query times out because it takes tooooo long...

Any ideas? ANY ideas at ALL would be helpful...

Comments
(1) This is basically a tree-traversal algorithm, but conversion into SQL is not always so straightforward. Starting from an arbitrary root node, we must visit every child node underneath, walking all the way down to the leaves.

(2) We tried a brute force algorithm which is fast for smaller sets, but impossibly long for sets where we're dealing with hundreds of employees. Any cheats? Caching results as we go? Any ideas out there?

Thanks,
Dan

Identify Genuine Stock Quantity Discrepancies Between ERP And WMS?

Dec 11, 2014

I have been asked to report on missing Stock in my works Warehouses. My work uses SAP Business One for ERP, and Accellos for Warehouse Management. Both SAP / Accellos maintain stock levels, and whilst they do talk to each other (in real time), nothing is perfect and stock counts (within each system) sometimes develop discrepancies.

Here is the code that I developed to show stock discrepancies -

Code:
SELECT
Tx.[Item Code]
, ISNULL(Ty.Qty, 0) AS 'A1 Qty'

Transact SQL :: Create Query For Last Stock Quantity?

Sep 10, 2014

I need to create query for last stock quantity.

I have 3 tables. Stores, Dates and Transactions. I want to combine all Stores with all Dates in one table and then calculate Last Stock Quantity.

Stores
London
Paris
Prague

Dates
1.1.2014
2.1.2014
3.1.2014

Transactions
1.1.2014 London 1000
1.1.2014 Paris 1300
1.1.2014 Prague 1500
2.1.2014 London 800
3.1.2014 Prague 1200

And result should look like this Last_Quantity should be Quantity for last date in Transactions table.

1.1.2014 London 1000
1.1.2014 Paris 1300
1.1.2014 Prague 1500
2.1.2014 London 800
2.1.2014 Paris 1300
2.1.2014 Prague 1500
3.1.2014 London 800
3.1.2014 Paris 1300
3.1.2014 Prague 1200

Power Pivot :: Stock Balance - Last Date

Oct 23, 2015

I am struggling with the Lastdate function. I have got stock balance data and want to show the number of products/models that are on stock at the latest date of the stock balance table.

My DAX formula is as follows:

=CALCULATE(DISTINCTCOUNT('3S-StockData'[Article Model]);LASTDATE('3S-StockData'[Date]))

I get the wanted results for all aggregated product groups, on product/model level however the formula does not give me the information wanted (see screenshot).

Basically, the formula calculates correct, but I want in my example only models shown with the date 2015-10-21.

Stock Age Query To Accept Multiple Rows As A Result

Jan 22, 2014

I worked with someone else to create a query that gives us the age of a stock. How long it has been in the warehouse since the Purchase order date (without completely selling out). It does exactly what I want, the problem is that it only accepts 1 row as a result.

The error message I get is:

quote:Msg 512, Level 16, State 1, Line 4

Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.

So my question is; can this code be modified to pass it multiple SKUS and run a report on every item currently in stock?

SELECT TOP 1
@skuVar, CAST(GETDATE()-ReceivedOn AS INT) AS 'Age'
FROM
(SELECT pir.id AS id,aggregateQty AS aggregateQty,-qtyreceived as qtyreceived, (aggregateQty - qtyreceived) AS Diff, ReceivedOn AS ReceivedOn
,(
SELECT SUM (PurchaseItemReceive.qtyreceived)
FROM bvc_product pp

[code].....

I use Microsoft SQL 2008
