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.
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.
I am new to SSAS and i want to try to build a "Sales" model. I will have some "Usage" data for some timespanns, but I am not quite sure how to tackle this. Is there somewhere a "Howto" for this?
Edit: There are several locations, and for each location a forecast is needed. And the Icing would be If I would be able to tell where my supplies must go 1st to achieve the best sales...
The potential Client wants to use Oracle but I would like to show them that SQL Server is the better tool for this ;)
I want to calculate the sum of actual sales until a date and forecast sales after a date.I am not sure what the best approach to this problem is, but I have tried my best with the following approach. Any better ways to solve this (using DAX).
I have created a parameter table that offers the last date of each month as possible choices to the user. I have tried to create a measure that sums actual sales up until this date.
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
Read only transacted replication to about 60 clients. 100 or so transactions a day (8 hours), transaction (record) is probably about 8K/transaction. Reliable connection over 100base-T. Latency - 15 minutes would be great.
This doable? -- I couldn't find a timing/ sizing model any place.
I have built a Sales Forecast model to predict the sales value. Along with making historic predictions for previous time periods I also want to retrieve the actual sales values for those periods.
How can I achieve this in a time series model?
I also would like to know how do mining models store the data.
Do they store the data in the same table/view format as their respecive data source view or in the Model Content format.
i am trying to find a way to link an 'initial' Sale ID of a product to 'future' Sale IDs of products that will trace back to the original Sale ID.For example, if I call the original sale , 'Sale ID #123', how can i link future Sale ID's (child[ren]) and all future sales to the original Sale ID #123? Can I use a Surrogate Key or similar function?
Parent:Sale ID #123 Children:Â Sale ID # 456, Sale ID #789, Sale ID #.....
how I can link the original Sales ID (Parent) to Sale ID's (child[ren]) of future purchases currently existing and in the future going forward?
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?
Attached is a file that generates a sample dataset from which I want to forecast a value for column 'Parcel Count 2014' from tomorrow (30/10/2014) till the end of December (31/12/2014). The forecast should be based on values from column 'Parcel Count 2013' for the same Month.
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:
I have create a simple tabular rolling forecast report (with cumulative totals) from today (October) thru the next 12 months that looks like this. It smartly works no matter when the report is generated, by starting with this CurrentMonth and moving forward by using 1,2,3,4,etc. in the dateadd: =MonthName(datepart("m",dateadd("m",1,Now())))
The report sample (formatting lost in dropping it in here):
Code Block
Close Pct October November December January February
25.% $0 $0 $26,625 $0 $0
50.% $237,500 $110,000 $262,500 $0 $0
75.% $56,250 $0 $891,075 $0 $0
90.% $1,051,830 $0 $0 $0 $0
Monthly Total $1,345,580 $110,000 $1,180,200 $0 $0
Cumulative Total $1,345,580 $1,455,580 $2,635,780 $2,635,780 $2,635,780
It is working fine....there doesn't seem to be anything wrong with it (all numbers total correctly, etc.), but it is very unelegant.....and I know there must be a better way.
In the righthand most month (which would be September 2008) column, I have a formula that produces the amount (the Monthly Total amount is the same):
I am currently using SQL Server version 6.5 and am trying to execute the BCP command from the command prompt to update my database. Right now, if the tables doesn't have any primary key constraints, the BCP works fine and inserts all the rows to the database. Suppose the table has some primary keys and the datafile to the BCP has some duplicate records in it. It says, the following
Starting copy... Msg 2627, Level 14, State 1: Server 'DHRUVA', Line 1: Violation of PRIMARY KEY constraint 'PK_docket_booking4_1__10': Attempt to insert duplicate key in object 'docket_booking4'.
It does not insert any rows to the database. Is there anyway I can overcome this error and proceed on with the BCP to copy data. THe datafile which I give will have duplicate records.
hi all,Please find below my queries, and help me to understand things..1. How to find the port number of a specific SQLServer instance?(I have heard that the different instance of the SQLServer runs in different port number)2. How to create a new instance for an existing SQLServer database? and how would i connect to it with my JDBC Connection string which usually reads as,jdbc:jtds:sqlserver://<Host_Name>:<Port_Number>/<DataBase_Name>Thanks in advanceShefu
i. If we have files and filegroups in place we have improved performance on backup and restore .Can we have any other improved perfortmance ? 2.If we are rebuilding or reorganising indexes on a table,which one will the degrades the performance more on the production server and which sits more on the transaction log. 3 how can we check the tableid in the database.
Hello i attended one interview . I have some doubts
1.) Indexes decreases the performance for insert ,UPDATE commands.? what will u do to increase the performance with these statements. 2.).tell me the 5 steps do u consider while writing a stored procedure to increase the performance.? 4).Is truncate a DDL or DML operation ? 5.) How to delete duplicate rows from a table? 6).table1 has an identity coluimn with 5 rows. delete opearation is performed on table 1.If user enters a new row what wiil be identity column no 1 or 6? table2 has an identity coluimn with 5 rows. truncate opearation is performed. .If user enters a new row what wiil be identity column no 1 or 6? 7.) when do we go for sub queries and when do we go for joins ? 8) could me tell the difference between sp and function.?
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?
Hi, I am totally new to sql server and have got a few doubts.I couldnt find it in earlier posts.Sorry if it is a repetition
*Can we get all the table names of a database by Query? *How to create a similar copy of a table by using AS..does this work in sql server 2000?(tried but showing error) *can we modify the column properties(like ensuring NOT NULL) after the table is created?
I am having this question in my mind from when I started using SSIS.. In a package I have an OleDB source and a flat file destination. and I hook up the source to destination in SSIS and run the package.. it works .. fine.. but internally what is done??? does SSIS performs BCP out ???
set @DN=@DN+'AA9999' select @ID = ID from TableA where status='A' and ColumnA like '%'+@DN ColumnA is NonClusteredIndex
When I use = symbol it goes for Index Seek (like below query) otherwise its going for table scan. Could anyone advice me which index need to be used for getting 'Index Seek' when I use like Operator. Basically TableA has millions of records.
select @ID = ID from TableA where status='A' and Code = 'AA9999'
soon soon, í´ll have to devellop some procedures to read an ASCII file to supply MS SQL tables. As I´ve read some old post, I´ve understand that I have to use BULK INSERT , or else, BCP or DTS. I´d like to know the diference between this commands and witch of them is more powerful, faster and efficient. If you can give me some implementation tips, I will be very grateful.
hi, here i am inserting the total dates between 1983/08/26 to 2006/08/26. i.e the table will have 36525 recoeds approximately. after executing the command i verified the table n i noticed that the last record in this table was 2025/xx/xx approximately. why? defualtly what is the capacity of a sql table. can i change the table properties to hold more num. of records. please help me on this.

I've to do a mining project and I intend to use the SSIS.
I've done a clustering plugin last year on analysis services and I also want to use it.
Let me try to explain the architecture of the process:
1) Receive data (read data from the database - these data are texts, actually)
2) Pre-process the data (transform the texts in a sparse matrix) using a new plugin
3) Call my clustering plugin and assign it to read the table created on the previous step
4) Call my KNN plugin to classify other pre-processed texts using the clusters found on the previous step as classes.
5) Show results.
Alright... It all running as a workflow on integration services
Here are my doubts:
A) How to view and use my plugin made for Analysis Services on Integration Services ? (is it possible or will I have to create another plugins from zero just to run on Integration Services ?)
B) Assuming the previous step is possible, how to modify my plugins to define inputs and outputs to do the correct communications between each plugin ? I think this is the most important question. Is it simple to do ? Is there any documented examples ?
I have 25 columns in my excel which is the second row in the excel. I have merged column comprising of 3-4 columns so like wise 7 columns as the 1st row. How can I suggest SSIS that 2ns row in the header or column names? Is there a way to validate values in each cell in excel for their data types using SSIS? Also is there any way using SSIS that I can refer to specific cell in the excel?
Here i am going to ask some questions in SSIS pls clarify my doubts...
1. Can i include a package with in another package? like If i have 20 packages..i need to run all packages at a time ..for this can i create a package and can i place all those packages in to a single package?
2. If i have 700 packages then how to run those packages all at a time?
3.Can i develop a Workflow or package in SSIS with out using Data Flow Tasks? Like with the help of only control Flow Tasks can i create a package or workflow?
I have a SQL cluster 2005 with 2 nodes. I involved a ETL (DTS) on SSIS.
I used OLEDB to get a connection ORACLE and INFORMIX.
I used a user and password to authenticate.
When I publish the package, to the Integration Services.
I publish it to the MSDB so in case that we have a failover that the package is the same.
However in case of switching server (failover) the package that I published on NODE 1 does not run on NODE 2.
And it fail:

I am currently using SQL Server 2000 server. I have run some BCP command to import data to SQL from CSV and Text files with the help of FORMAT files through Windows Scheduler.
My doubt is, if I swich to SQL Server 2005, whether the same BCP commands will supported? If no, What are the things I need to do to run the BCP commands in 2005 as in 2000?
I heard that the BCP utility is no longer support in 2005 and this can be done thru SSIS utility. Is it right...? Is SQL Server 2005 support to use the BCP commands without going to SSIS utility?
I have a report which totals sales by customer. Then table footer has a grand total of all customer sales. I would like to get a percent of each customer's sales against the total sales. How do I get the sum from the table footer to use in an individual customer row?
