MS SQL Server :: Rolling Data In Forecast And Cumulative Totals Question

Transact SQL :: Cumulative Totals - Rolling Window

Aug 14, 2015

I'm trying to generate a cumulative total with a rolling window of 13 time periods..Previously I was able to do left outer join to the same table 13 times to add the quantity field but it appears with the migration to SQL Server 2014, that many left outer joins is not possible (query that would run in 3 mins is taking well over 15 hours now)..

Trying To Get Daily Totals From Cumulative Totals In A Pivot

Oct 2, 2006

I have been providing sales data for a few months now from a table that is set up like this:

Date WorkDay GasSales EquipmentSales

9/1/2006 1 100.00 200.00

9/4/2006 2 50.00 45.00

etc.

As can be seen, the data is daily, i.e., on the first workday of September we sold one hundred dollars in gas and two hundred dollars in equipment. On the second workday of September we sold fifty dollars in gas and forty-five dollars in equipment.

Now, however, the data I have to pull from is cumulative. So, using the last table as an example it would look like this:

Date_WorkDay_GasSales_EquipmentSales

9/1/2006 1 100.00 200.00

9/4/2006 2 150.00 245.00

etc.

To make things more complicated, the powers that be wanted this data presented in this fashion:

Total Sales:

1_2_etc.

300.00 95.00 etc.

So, I have been doing a pivot on a CRT to get the data to look like I want. The code is like this:

with SalesCTE (Month, WorkDay, [Total Sales])

as

(

SELECT

datename(month, cag.date),

cag.WorkDay AS [Work Day],

sum(cag.sales_gas + cag.sales_hgs) AS [Total Sales]

FROM CAG INNER JOIN

Branch ON CAG.[Oracle Branch] = Branch.OracleBranch

group by cag.date, cag.WorkDay

)

select * from SalesCTE

pivot

(

sum([Total Sales])

for WorkDay

in ([1],[2],[3],[4],[5],,[7],,[9],[10],[11],[12],[13],[14],[15],[16],[17],[18],[19],[20],[21],[22],[23])

) as p

So, my question is:

How do I get the data to give back daily totals instead of the cumulative amounts for each workday? If the query was a simple one, I'd do something like

select [1] as [Day 1], [2]-[1] as [Day 2], [3]-[2] as [Day 3], etc.

but the query is far from normal, with the CRT and the pivot. I can't seem to get it to work how I'd like.

Any advice/answers? Thanks in advance!!!

P.S. I don't know how to get it to quit with the freakin' smileys.... I suppose you can figure out what my code is really supposed to look like above. Needless to say, it doesn't include a devil face and a damn music note...

Using SET As An Alternative To Cursors For Rolling Totals

Sep 4, 2001

I had a need to update a column in a table with a calculated value based on the value of the preceeding value in the table (which in turn was based on the preceeding value, etc...).

Although this can easily solved via a cursor, I was able to solve this with a single set statement that first updates a variable (which can be part of a calculation using the 'current' row) and using the knowledge that SET statements are applied 'in order' (top-down).

Most importantly: the technique relies on my observation that the SET statement processes a table in clustered index sequence, or load sequence in a heap table.

I've included a very simple example of this technique below.

I'm curious if anyone is using this (undocumented?) technique and if my assumptions are valid (I'm using this on much larger tables with more complex calculations).

EXAMPLE:

CREATE TABLE #tmp (
num int IDENTITY(1,1) NOT NULL,
val int NULL)

-- load 100 test rows
DECLARE @x int
SET @X = 1
WHILE @X <= 100
BEGIN
INSERT #tmp (val) VALUES (NULL)
SET @X=@X+1
END

DECLARE @i int
SET @i = 1

UPDATE #tmp -- this is a -very- simple example of technique!
SET @i=num+@i, -- @i now has current totaled value + current-row int value
val=@i -- val now stores current subtotal

Rolling 12M Totals Performance Issues

May 15, 2008

Hi,

We are using SQL Server 2005 Analysis Services in x64 environment.

We use many 12M metrics implemented as calculated measures. A typical 12M calc measure looks like this:

Sum({LastPeriods(12, ClosingPeriod([Time].[Month],

Tail(Existing [Time].[Month].Members).Item(0)))}

, [Measures].[Revenue])

, FORMAT_STRING = '#,#';

The front end is based on OWC.

These are performing extremely poorly and worse compared to our older SQL Server 2000 environment. Is there anything obvious from this formula that would make it worse?

I appreciate any guidance as to what I should look for.

thanks
MJ

Carrying Cumulative Totals Over Months

Apr 11, 2008

I am making a report for a car dealer. Each month a certain number of cars will be placed on the lot and a certain number will be taken off. I want to make a report that will show the inventory levels at any point in time. (I will further refine the report by color, origin, model, etc later.) I am currently listing each car in my inventory table, flagging it with a "removed" flag when it is sold. My flag for adding a car is 1 and removing a car is -1. It's easy enough to sum the table and get the current inventory level but I'm having trouble looking back over time.

Say in January I had 35 cars on the lot. I sold 20 and added 5. In February I sold 9 and added 10. In March I sold 12 and added 5.

I need the report to break every month. But on the break I need to add all the cars in the table minus cars sold. For the January report it should show a total (cars added - sold) in the table. Each month I need to take a new grand total of all cars added minus cars sold up to the end of that month OR cars added that month minus cars sold that month added to the running total from the previous month.

Is there some sort of calculate measure I could stick in my cube that would carry these totals? Or any other ideas?

Thanks.

Analysis :: SSAS Planning / Forecast Copy Data In Cube

Oct 2, 2015

Is there any way to copy my Data of 2015 to the Planning/Forecasting Value of 2016?

My question is based on that we use INFOR ION BI right now and there we can just add an Button in our reports wich physically copies the value from one year to the next year based on some other rules in the cube.

Now I need to make this example work with SSAS and Excel PivotTables but I cant figure out how.

I have absolutely no clue where and how to accomplish it. Do I use Calculations, do I use Actions, do i make it in the Dataview, Cube or directly in Excel?

Reporting Services :: Calculating Grand Totals From Group Totals

May 9, 2015

I have some data grouped in a table by a certain criteria, and for each group it is computed a subtotal for the group. Of the values from each of the group, I want to create a grand total on the report by adding every subtotal from each group.

Example:
...
....
Group1 Value
10
20
Sub Total 1: 30

Group2 Value
15
25
Sub Total 2: 40

Now, I would like to be able to add subtotal 1 (30) to subtotal 2 (40) and my grand total would be 70. Can I accomplish this task in SSRS?

Forecast Model

May 24, 2006

Hi

I am new to Data mining in SQL Server. I am using SQL 2005 to create a forecast model for Product sales. I two fact tables that I am using. One has all the Orders historically with the line item details. The other table is a time dimension table which has the value of each of the time values referenced in the Orders. So the time dimesion has multiple values for one day as it goes down to the hour the order was placed.

Can I create a forecast using the time series algorithm in the Data mining module. When I tried to use this algorithm, I got an error that the time is not synchronized with starting series "Unknown" and I should try to set the missing_value_Substitution parameter to previous.

Can some one explain to me how this will resolve my issue. I read in one of the articles on Data mining that in order to use the time series algorithm , I need to have unique set of values for the time. Can some one help me with this

Thanks

TimeSeries Forecast Period

Nov 16, 2006

Using the TimeSeries algorithm, how do I forecast more than one time period ahead? I read in you book on page 182 that PredictTimeSeries function can take a parameter for the number of time periods you want to predict. Fore example, SELECT PredictTimeSeries(Bread,5) tells the algorithm to predict the next 5 time periods. Can you tell me how to change that parameter using the graphic interfaces?

Thanks!

Doubts Regarding Sales Forecast Model

Aug 5, 2006

I have few more clarification regarding time series.
Firstly
In my model the month level product sales value represented across 1st day of every month. So that the key time column is of datetime datatype containing a sequence of dates representing the 1st day of every month of the year.
Eg: 2006-01-01, 2006-02-01��. etc. all in (yy-mm-dd) format
But
when I make prediction for next five months, though it makes monthly
predictions the date part for the months are random whereas I expect
the date part to be 1st of every month. What is the reason for this and how can I overcome it.
Secondly
Predicted
sales values for some time period are negative though I do not have any
negative value in the training data. What is the reason for this and
how can I rectify it?

Thirdly
In
one of your earlier posts you had said that the time series algorithm
does not have any built in time intelligence but uses the key time
column as a time sequence stamp. So If have to make predictions for a
particular time period where the time slice for each time period is 25
days or 50 days etc, then I understand that the input data used to
train the model should be in the same time sequence.
Or
Can I specify the span of the time period according to which the prediction needs to be made?
Basically
how can I use the same time series model to make monthly, yearly,
quarterly, daily or predictions or for custom time period like I have
mentioned above.

T-SQL (SS2K8) :: Query That Can Provide 6 Month Forecast?

Dec 17, 2014

Background is that I am recreating charts in SSRS that were being created in Excel. The source data is residing in a SQL Server database. I'm having a hard time coming up with a SQL query to provide a 6 month forecast. I can get my data into a pivot (within a stored procedure) in the following format:

Period---------Date--------------------------------Percent
1--------------2013-11-01 00:00:00.000---------0.3762
2--------------2013-12-01 00:00:00.000---------0.3584

4--------------2014-02-01 00:00:00.000---------0.3292
5--------------2014-03-01 00:00:00.000---------0.3519

[Code] ....

I need to forecast the next 6 dates 12/1/2014 thru 5/1/2015 using the last 6 months in the data set (periods 8 thru 13)

Period---------Date--------------------------------Percent-------Forecast
1--------------2013-11-01 00:00:00.000---------0.3762
2--------------2013-12-01 00:00:00.000---------0.3584

5--------------2014-03-01 00:00:00.000---------0.3519
6--------------2014-04-01 00:00:00.000---------0.4064

[code].....

how to use the first table to generate the forecast values in the second table.

Problem With Historical Prediction In Sales Forecast Model

Aug 2, 2006

Hi,

I have built a time series model to forecast sales value

I have data from jan 2004 to jan 2006 and the sales value is
at a day level in my database. But I am aggregating it to month level in the
DSV of the mining model.

I am required to make only historical predictions using the
above model starting form jan 2004 to jan 2006 for every month.

I have set Historical_Model_Count
and Historical_Model_Gap parameter
values to 24 and 10 respectively, and trying to predict for the past few months
(PredictTImeseries(SalesValue,-1,1))

But its throwing me the following error

Error(Data Mining): A time series
prediction was requested with a start time further in the past than the
internal models of the mining model, Sales Forecast, specified in the
HISTORIC_MODEL_GAP and HISTORIC_MODEL_COUNT parameters can process

In fact it throws the above error irrespective of what the Historical_Model_Count and Historical_Model_Gap parameter values
are

I am not able to figure our why this problem is happening?

What should the parameter values for the above scenario?

It would also be helpful if I can get an explanation on how
these two parameters affect the historical predictions. I kind of understand
that these two parameters are important for historical predictions but don��t
know why or how.

Rolling 13 Months In Query

Jun 23, 2008

Hi,

I'm writing a query that will be calculating a number of business performance measures including the following...

Average Stock:
This is calculated by taking the actual stock value of the product category per month and dividing it by 13 if we have over 12 month's history, or if a new product, then by the number of months we have had it in stock for.

Cost of Goods Sold Annualised:
This is an average figure for the year of the sold landed costs for the product category over a 13 month period if we have over 12 months history. If it's a new product, then it's for the number of months we have had stock.

My question is, how do I tell the query to go back 13 months from the current month?

Rolling Month Graph

Feb 12, 2007

Hi,

trying to develop a report that shows the sum total for each month during a specified date range.

I have parameters asking for the start date and end date of the date range, the report needs to show the months in between this date range.

One of the fields in the dataset is durationminutes which I need to sum for each month then divide by 60 to show hours. I then need to show the total of each month in a bar graph (with each month along the x axis).

If anyone can shed some light on how I am going to do this it would be greatly appreciated.

Mirroring Between SP1 And SP2 For Rolling Upgrade

Jun 15, 2007

Is database mirroring compatible between SQL Server 2005 (Standard Edition) SP1 and SP2? I currently run SP1, and will shortly be introducing a failover partner. I'd like to have the failover partner installed as SP2, start the mirroring, manually failover, then upgrade the existing server to SP2 as well.

Is this a supported upgrade method, or will I need to upgrade the existing server to SP2 before setting up database mirroring? The SP2 installation instructions and readme file don't appear to mention mirroring at all (at least not that I can find).

Many thanks for any assistance.
