Nested Case Prediction Query Question
Jul 19, 2007
I have a question about what is possible with a prediction query
against a nested table. Say I have a basic customer-product case and nested table mining model like so:
Mining Model DT_CustProd
(
[Id] ,
[Gender] ,
[Age]
[Products] Predict
(
[ProductName] ,
[Quantity]
)
)
Using Microsoft_Decision_Trees
I can write a query to find the probability of product (and quantity) A like so:
SELECT (select * from Predict(Products,INCLUDE_STATISTICS)
where ProductName = 'A' )
FROM DT_CustProd
NATURAL PREDICTION JOIN
(SELECT 'M' AS [Gender],
27 AS [AGE] ) AS t
What if I know that the query customer (M,27) in question has purchased product B, how can I use that in the prediction join to predict product A? The fact that product B was purchased might influence the prediction, right?

Hi,
Can i use a CASE statement in a prediction query.
the following query is throwing me an error
SELECT
CASE [Sales Forecast Time Series].[City Code]
when 'LA' then 'Los Angeles'
WHEN 'CA' THEN 'California'
ELSE 'OTHERS'
END,
PredictTimeSeries([Sales Forecast Time Series].[Sales Value],5)
From
[Sales Forecast Time Series]
ERROR:
Parser: The statement dialect could not be resolved due to ambiguity.
Also
Is it possible to discretize the
Sales Value column using a the CASE statement, the output column of
PredictTimeSeries function.
Is there a link that can give me a
comprehensive info on what can be achieved and what cant be using DMX queries

If your prediction join is to a SQL datasource, you can easily write a SQL query which returns a nested table like:
SELECT
Predict([Subcategories],2) as [Subcategories]
FROM
[SubcategoryAssociations]
NATURAL PREDICTION JOIN
(SELECT
(SELECT 'Road Bikes' AS Subcategory
UNION SELECT 'Jerseys' AS Subcategory
) AS Subcategories
) AS t
What about if your datasource is a cube? Is there some special MDX syntax similar to the SQL syntax above? Or do you have to utilize the SHAPE/APPEND syntax as follows?
SELECT t.*, $Cluster as ClusterName
FROM [MyModel]
PREDICTION JOIN
SHAPE {
select [Measures].[My Measure] on 0,
[My Dimension].[My Attribute].[My Attribute].Members on 1
from MyCube
}
APPEND (
{
select [Measures].[Another Measure] on 0,
NON EMPTY [My Dimension].[My Attribute].[My Attribute].Members
*[Product].[Product].[Product].Members on 1
from MyCube
}
RELATE [[My Dimension]].[My Attribute]].[My Attribute]].[MEMBER_CAPTION]]]
TO [[My Dimension]].[My Attribute]].[My Attribute]].[MEMBER_CAPTION]]]
)
AS [My Nested Table] AS t
ON [MyModel].[Product].[Product] = t.[My Nested Table].[[Product]].[Product]].[Product]].[MEMBER_CAPTION]]]

What's wrong with this...
Code:
SELECT case when tab1.col2=tab1.col3 and tab1.col3!=0
then (SELECT tab3.col3 FROM tab3)
else (case when tab5.col2=tab5.col6
then (SELECT tab7.col1 FROM tab7)
else (case when tab1.col2=tab1.col3 then tab1.col4+7 end)
end as value
From tab5, tab1
WHERE tab1.col1=tab5.col1
I get the error as-
Server: Msg 156, Level 15, State 1, Line 6
Incorrect syntax near the keyword 'as'.

Hello,
I've got a SP that selects the best price from a table that has all info collected into it. Selecting the price is easy, I use COALESCE.
But I want to have a column next to it that contains which price that was choosen. I used CASE and nested it... worked fine until I reached the 10th level, there is a limit there.
"Case expressions may only be nested to level 10."
I'm sure som people will puke when they see this code and I'm open to suggestions on how to do it in another way. I can always do it in two queries, but it should be possible to do it in one.
I was looking at IF, THEN, ELSE, but I don't find any way to use it in a query, just to determine WHICH query will be run.
Here is my SP (how can I get it in a nice grey area like som people post?):
CREATE PROCEDURE dbo.ProcCOST_SET_TC AS
/* Empty TC table */
truncate table dbo.COST_TC
/* Collect info */
INSERT INTO dbo.COST_TC
SELECT REGION,PROJECT,CPN,
COALESCE (
Contract_usd,
SITEINPUT_sitecontract_usd,
SITEINPUT_lastPO_usd,
SITEINPUT_lastreceipt_usd,
SITEINPUT_other_usd,
SITEINPUT_wac_usd,
SYSTEM_Min_ContractPrice_usd,
SYSTEM_Min_OpenOrder_usd,
SYSTEM_Last_Receipt_usd,
SYSTEM_Min_WAC_usd,
[BP Q-1]
),
Case Contract_usd WHEN IsNull(Contract_USD,0) THEN 'Contract' ELSE
Case SITEINPUT_sitecontract_usd WHEN IsNull(SITEINPUT_sitecontract_usd,0) THEN 'SITEINPUT Site Contract' ELSE
Case SITEINPUT_lastPO_usd WHEN IsNull(SITEINPUT_lastPO_usd,0) THEN 'SITEINPUT Last PO' ELSE
Case SITEINPUT_lastreceipt_usd WHEN IsNull(SITEINPUT_lastreceipt_usd,0) THEN 'SITEINPUT Last Receipt' ELSE
Case SITEINPUT_other_usd WHEN IsNull(SITEINPUT_other_usd,0) THEN 'SITEINPUT Other' ELSE
Case SITEINPUT_wac_usd WHEN IsNull(SITEINPUT_wac_usd,0) THEN 'SITEINPUT WAC' ELSE
Case SYSTEM_Min_ContractPrice_usd WHEN IsNull(SYSTEM_Min_ContractPrice_usd,0) THEN 'Min Contract Price' ELSE
Case SYSTEM_Min_OpenOrder_usd WHEN IsNull(SYSTEM_Min_OpenOrder_usd,0) THEN 'Min Open Order' ELSE
Case SYSTEM_Last_Receipt_usd WHEN IsNull(SYSTEM_Last_Receipt_usd,0) THEN 'Last Receipt' ELSE
Case SYSTEM_Min_WAC_usd WHEN IsNull(SYSTEM_Min_WAC_usd,0) THEN 'Min WAC' ELSE
Case [BP Q-1] WHEN IsNull([BP Q-1],0) THEN 'BP Q-1' ELSE
'NO DATA' END END END END END END END END END END END
FROM COST_AllInfo
GO

Suggestions (don't hit me to hard)?

Hi, I'm not new to SQL however I get confused when I transfer from different DBMS like Oracle, SQL Server, Firebird, MySQL and Access.
in SQL Server T-SQL, How do I go about a nested select case like the ff: And I supposed to use this as source for a Cross-Tab.
CREATE PROCEDURE SP_SAMPLE(
@DateStart datetime,
@DateEnd datetime,
@Param1 char(3),
@Param2 char(1),
@Param3 decimal(7,4))
AS
BEGIN
SELECT
Field1,
Field2,
Field3,
CASE
WHEN FieldSomething = 0.0000 THEN '*'
WHEN FieldSomething < @Param3 THEN '_'
ELSE
CASE @Param2
WHEN 'A' THEN SomeOtherField1
WHEN 'B' THEN SomeOtherField2
WHEN 'C' THEN SomeOtherField3
END
END Alias1
FROM SampleTable
WHERE UPPER(Field2) = UPPER(@Param1)
AND Field1 BETWEEN @DateStart AND @DateEnd
ORDER BY Field2, Field3, Field1
END
it has this error:
Error converting data type varchar to numeric.

Hi All,
I'am trying to program a nested CASE statements (if this is not possible, does anyone have any alternate suggestions ?) and I'm getting syntax errors.
The statement is:
SELECT @cmdLine =
CASE @BackupType
WHEN 1 THEN Select @tmpStr =
CASE @initFlag
WHEN 1 THEN 'BACKUP Database ' + @databaseName + 'TO '+ @backupDeviceName + ' WITH INIT, NOUNLOAD, NAME = ' + @backupJobName + ' , SKIP , STATS = 10, NOFORMAT'
ELSE 'BACKUP Database ' + @databaseName + 'TO '+ @backupDeviceName + ' WITH NOINIT, NOUNLOAD, NAME = ' + @backupJobName + ' , SKIP , STATS = 10, NOFORMAT'
END
WHEN 2 THEN Select @tmpStr =
CASE @initFlag
WHEN 1 THEN 'BACKUP Database ' + @databaseName + 'TO '+ @backupDeviceName + ' WITH DIFFERENTIAL, INIT , NOUNLOAD, NAME = ' + @backupJobName + ', SKIP, STATS = 10, NOFORMAT'
ELSE 'BACKUP Database ' + @databaseName + 'TO '+ @backupDeviceName + ' WITH DIFFERENTIAL, NOINIT , NOUNLOAD, NAME = ' + @backupJobName + ', SKIP , STATS = 10, NOFORMAT'
END
WHEN 3 THEN Select @tmpStr =
CASE @initFlag
WHEN 1 THEN 'BACKUP Log ' + @databaseName + 'TO '+ @backupDeviceName + ' WITH INIT, NOUNLOAD, NAME = ' + @backupJobName + ', SKIP , STATS = 10, NOFORMAT'
ELSE 'BACKUP LOG ' + @databaseName + 'TO '+ @backupDeviceName + ' WITH NOINIT, NOUNLOAD, NAME = ' + @backupJobName + ', SKIP , STATS = 10, NOFORMAT'
END

Hi i am having some trouble with a nested case statement, what i want to do is set the value of a new column called Result depending on a series of case statements. Basically i want to check Test.Webstatus = 'Rd' and FinalResult = 'true' if this is true i want it to set the value in the Results field to ReportableResult + '~' + ReportableUnitDisplay then go through all the limits fields adding either the value of the field or 'blank' onto the end of the value in the Results field, depending on if the limits field has Null or a value in it. Producing a value in the Results field similiar to: 10~kg:10:5:2:1 or 10~kg:blank:5:blank:1 etc
select ClientRef, Sample.WebStatus as SampleStatus, Analysis, FinalResult, Test.WebStatus,
'Result' = Case
when Test.WebStatus = 'Rd' and FinalResult = 'true' then
Case
Case
when UpperCriticalLimit is null then ReportableResult + '~' + ReportableUnitDisplay + ':blank'
else ReportableResult + '~' + ReportableUnitDisplay + ':' + UpperCriticalLimit
end
Case
when UpperWarningLimit is null then ReportableResult + '~' + ReportableUnitDisplay + ':blank'
else ReportableResult + '~' + ReportableUnitDisplay + ':' + UpperWarningLimit
end
Case
when LowerWarningLimit is null then ReportableResult + '~' + ReportableUnitDisplay + ':blank'
else ReportableResult + '~' + ReportableUnitDisplay + ':' + UpperWarningLimit
end
Case
when LowerCriticalLimit is null then ReportableResult + '~' + ReportableUnitDisplay + ':blank'
else ReportableResult + '~' + ReportableUnitDisplay + ':' + LowerCriticalLimit
end
end
when FinalResult = 'false' then Null
else Test.WebStatus
from Job
inner join sample on Job.JobID = Sample.JobID
inner join Test on Sample.SampleID = Test.SampleID
left join Result on Test.TestID = Result.TestID
Any Advice Would Be Great
Thanks

I'm fairly new to SQL. I have a function in Excel that I'm trying to translate to SQL to run my query.
Basically what i want to do is if Date1 and Date2 are blank then display Date Not Tracked.
Else if Date1 is blank however Date2 has a value then pull Date2 other wise Date1
This is my Excel function:
=IF(AND(A2="",B2=""),"Date Not Tracked",IF(A2="",B2,A2))
A2 = Product.Date1
B2 = Product.Date2

Hi all,
I have a Sproc. to get records and I was looking to use a nested CASE statement
The thing is that first I want to check the availability of single quote in my where statement and replace it with double quote. The second case is to check for a given condition and make some calculation. The following statement is not running. So would you mind helping me in this regard?
Thank you in advance:
(CASE WHEN CHARINDEX(''ca.caCode'',''' + replace(@WhereStmt, char(39), char(39) + char(39)) + ''') > 0 THEN ca.ClusterAmount ELSE dbo.vwGrantsMaster.CurrentValueTotalCost END CASE WHEN dbo.vwGrantsMaster.StatusCode IN (3) THEN (IsNull(dbo.vwGrantsMaster.CurrentValueTotalCost, 0))-(IsNull(dbo.vwGrantsMaster.AwardedTotalCostAmount,0)) ELSE dbo.vwGrantsMaster.CurrentValueTotalCost END) AS CurrentValueTotalCost,

Is it possible to use nested case statements in the SQL for your dataset when you are using Reporting Services? I keep getting an error saying "Unable to parse expression" and my report won't run.
Code SnippetCASE WHEN (CASE WHEN DateDiff(d , GetDate() , DATEADD(d , - 1 , DATEADD(m , 1 , DATEADD(m , 1 , DATEADD(d , - (1 * (DAY(TRANSACTION_DATE) - 1)) , TRANSACTION_DATE))))) < '0 THEN 'Overdue' WHEN DateDiff(d , GetDate(), DATEADD(m , FIELD1 / 30 - 1 , DATEADD(m , 1 , DATEADD(d , - (1 * (DAY(TRANSACTION_DATE) - 1)) , TRANSACTION_DATE)))) > 0 THEN 'Not Due' ELSE 'Due' END)= 'Not Due' AND FIELD2 > 0 THEN DateDiff(m , GetDate() , DATEADD(m , FIELD1 / 30 - 1 , DATEADD(m , 1 , DATEADD(d , - (1 * (DAY(TRANSACTION_DATE) - 1)) , TRANSACTION_DATE))) * 30) / 360 * FIELD2 * @PARAMETER1 ELSE NULL END
I know this is quite a complex statement, so at first I was worried that maybe I had brackets in the wrong places, but I've been through the code and made sure that every opening bracket has an equivalent closing bracket, and everything appears to be OK in that respect. So I'm thinking that maybe the structure of my nested case statements is incorrect? The inner case statement is necessary to calculate whether a transaction is due, overdue or not due. The outer case statement depends on the result of the inner case statement.
Basically, we only want the calculations following the "THEN" in the outer case statement to be executed if the result of the inner case statement is "not due" and Field2 is greater than zero. If either of those criteria aren't met, then it should go straight to the ELSE NULL END statement and stop.

I am attempting to create a view to bring together multiple joined tables based ona one to many relationship
Eg Table1 contains code, address
Table2 contains code, financial details
table3 contains code, financial history
This view is then going to be used to update a table with only one record for each 'code'. i.e. NewTable = code, add1, add2, city, prov, postal, financialvalue, history value1, history value2
My current stumbling block is:
One of the fields in table1 is a free format address field (address).
eg. could be (street addres, city prov, postal)
or
could be (street address 1, address2, address 3, city prov, postal)
I want to be able to assign individual components of the address to corresponding fields
if # of commas = 2 then
address1 = substring(address,1, position of first comma)
cityprov = substring(address,possition of first comma, position of second comman)
postal = substring(address rest of field)
I have a UDF which returns the number of commas but I cannot figure out how to use either a nested case statement to parse the string...
ANy ideas on how best to accompish this?
( this table is needed for some leacy software which can only handle one record with all infor....

Hi,
I get the following issue:
Server: Msg 125, Level 15, State 4, Line 16
Case expressions may only be nested to level 10.

hi
Here are the two tables again.
1)PATIENT(PATIENT_ID,NAME,CITY)
2) DISEASES(DISEASE_ID,NAME)
I am trying to select patient table as case and diseases table as nested to create an association model. i m getting following error.
Disease table cannot be used as a nested table because it does not have a many-to-one relationship with the case table. You need to create a many-to-one relationship between the two tables in the data source file.
i have created a relationship by dragging Disease_id from diseases table on Patient_id in patient table. when i am trying to select Patient_id as key, City as input, it is not showing disease_id to choose as a predict column.
please suggest me if i am doing anything wrong? i have not done any thing to do my datbase, just selected the tables i want to create an association model on and trying to create association model.
your help and insight is highly appreciated.

Hi,
I have a problem in design the tables. My main task is to learn how to give the Match Score.
I have hundreds of dataset and one of them is like this:
Test Record Number: 19
Prospect ID = 254040088233400441105260031881009
Match Score = 95
Input Record Fielding ( eg wordnumber[Field] ) : 1[1] 2[1] 3[11] 4[11] 5[11]
Prospect Word = 1 type = 1 match level = 4 input word = 1 input type = 1
Prospect Word = 2 type = 2 match level = 0 input word = NA input type = NA
Prospect Word = 3 type = 3 match level = 4 input word = 2 input type = 1
Prospect Word = 4 type = 11 match level = 4 input word = 3 input type = 11
Prospect Word = 5 type = 13 match level = 4 input word = 4 input type = 11
Prospect Word = 6 type = 14 match level = 4 input word = 5 input type = 11
Now I have all my data stored in the DB and I seperated them into 3 tables and their structures are:
1) prospect (id, testrecordnumber, prospectID, matchscore)
2) inputfieldind (id, prspid, inputword, inputfield)
3) prospectinfo (id, prspid, prospectword, prospecttype, matchlevel, inputword, inputtype)
and the prspid in table 2 & 3 refers to the prospectID in table 1.What I did was setting:
a) prospect table as case table with id AS key, prospectID AS input & predictable;
b) and the other two as nested tables with inputword/inputfield AS key & input, prospectword/prospecttype/matchlevel/inputword/inputtype AS key & input .
But it shows error for having multiply key columns...
And also I am thinking about using the Naive bayes algorithm. Can I also have some suggestion on this?
Thanks

hi
i m trying to build microsoft association model using Microsoft association algorithm. i got
1) patient table(patientid, name, city)
2) diseases(diseaseid, dieseasename)
It is M:N [many to many] relationship between above tables, so
3)Patient_diseases(patientid,disease_id). [RELATIONSHIP TABLE]
i am trying to associate city in patient table --> disease in diseases table. I want to build association data mining model and use it on web form, such a way when the user enters city associated disease will be displayed.
should i select all 3 table to build the model? could help me to decide what tables should i select as Case and what tables as Nested? what attributes from the table should i select as key, input, predictive ?
i am using data mining tutorials on sqlserverdatamining.com to build this model. is there anything further during my model building i get into confusion? please suggest me where i can find complete resource or inform here.
i appreciate Mr.Jamie for his guidance so far in my academic project. i do have the book 'Data mining with sql server 2005'. I left with just one day to do this and document.
hoping someone could suggest. your help is much appreciated.

Hi
After building a model in BI, I want to view the chart of model in mining model viewer, in the chart tab I can just see one prediction value that means for my model do prediction for some time slice and in prediction steps I can specify how many steps, I want to show this chart
In mining model viewer tab we can see the chart of prediction also decision tree and the chart is for showing all of value prediction, and with choosing prediction steps we can specify that show just one value prediction or two or several values. But sometime I can see just one value in chart and sometime I can see several values in chart,
This difference is for my data or no?
And also for viewing historic prediction I should choice €œshow historic prediction€? and before that I should set
Two parameters: Historic_ model _count and historic _model _count,
But I can€™t see historic prediction (sometime this happens)
Please help me.

Hello. I'm trying to reduce some code in my stored procedure and I'm running into lots of errors. I'm somewhat of a novice with SQL and stored procedures so any help would be beneficial.
I have a SP that gets a page of user data and is also called when sorting by one of the columns (this data is placed in a repeater, btw). I quickly learned that I wasn't able to pass in string parameters the way I had hoped in order to handle the ORDER BY and direction (ASC/DESC) so I'm trying to work around this.
So far I've tried the following with many errors.WITH Users AS (
SELECT ROW_NUMBER() OVER (ORDER BY CASE WHEN @OrderBy='FirstName' AND @Direction='DESC' THEN (FirstName + ' DESC')
WHEN @OrderBy='FirstName' THEN FirstName
WHEN @OrderBy='LastName' AND @Direction='DESC' THEN (LastName + ' DESC')
WHEN @OrderBy='LastName' THEN LastName
END
) AS Row,
UserID, FirstName, LastName, EmailAddress, [Role], Active, LastLogin, DateModified, ModifiedBy, ModifiedByName
FROM
vRF_Users
)
SELECT UserID, FirstName, LastName, EmailAddress, [Role], Active, LastLogin, DateModified, ModifiedBy, ModifiedByName
FROM Users
WHERE Row BETWEEN @StartRowIndex AND @EndRowIndex
I've tried a combination of similar things with parenthesises, without, doing "THEN FirstName DESC" without concatenating anything, etc.
I also tried: DECLARE @OrderByDirection varchar(32)
DECLARE @DESC varchar(4)
SET @DESC = ' DESC'
IF @Direction = 'DESC'
BEGIN
SET @OrderByDirection = (@OrderBy + @DESC)
END
And then writing my case statemet like this:ORDER BY CASE WHEN @Direction='DESC' THEN @OrderByDirection
ELSE @OrderBy
ENDObviously this didn't work either. Is there any way to gracefully accomplish this or do I just have to use a bunch of if/else statements and lots of redundant code to evaluate all my @OrderBy and @Direction parameters???
Thanks in advance,
Jen

Hello , i have 2 seperate tables of information about people.
Table A :with a key column Anumber contains mobile telephone numbers and
table B : with a key column named Bnumber contains mobile telephone numbers
These two key columns have the same data type and hold the same information (mobile phone numbers).
Some mobile numbers from table A exist in table B so i wanted to run a clustering algorithm in order to gain information from the two tables.
I created a new table C with all the distinct MobileNumbers found in the tables A and B ,set the Cnumber column as key columns and linked it with the equivalent columns Anumber , Bnumbers from tables A and B.
A--->C <---B

http://i115.photobucket.com/albums/n310/Slavetodark/Sql/1-1.jpg
Although, when i desing a training model in the Business intelligent Studio ( New mining structure) and set table C as case table and A and B as nested tables in the "DataMiningWizard>Specify the columns used in your analysis" window the key columns from table B and C DO NOT appear at all
So if i click next i get a warning (You have not defined a key column for the nested tables).
I proceed, put the key columns manually from the mining structure tab (drag and drop the key columns from the data sourve view) but when i run the clustering algorithm the results doesnt at all make sence as you can see at
http://i115.photobucket.com/albums/n310/Slavetodark/Sql/4.jpg
http://i115.photobucket.com/albums/n310/Slavetodark/Sql/3.jpg
Do you have any suggestions about what might got wrong? Is it a bug or something i did?
Thnx for your time and sorry for the huge post!!

Hi,
I have the following
association model Structure
Where I am trying to find out
the associations between various service activities so that when a customer
buys a service activity we can recommend him/her others
CaseTable
CustomerId à Key
IncidentId
Nested Table
ServiceId à Key
ServiceName à Input, Predict
IncidentId à Link to the case table
Firstly is the above
structure correct??
Secondly
I have the following prediction
query
SELECT
t.[ServiceId],
Predict
([ServicerossSell].[ServiceCross-SellRecommend],3)
From
[ServicerossSell]
PREDICTION JOIN
SHAPE
{OPENQUERY([Adventure
Works Cycle MSCRM],
'SELECT DISTINCT ServiceId
FROM Service ORDER BY ServiceId]')
}
APPEND
( {OPENQUERY([Adventure Works Cycle MSCRM],
'SELECT DISTINCT ServiceId
FROM Service ORDER BY ServiceId]')
}
RELATE
[ServiceId] To [ServiceId]
)
AS
[Service]
AS t
ON
[ServicerossSell].[ ServiceCross-SellRecommend].[ServiceId]
= t.[Service].[ServiceId]
It throws the following error
€œThe DMX column was not found in the context€?
I am not able to figure out why, any help would be most
appretaiated

Hi!
I'm building a mining model wiht MS Association Rules. After processing this model, the result includes some rules(example):
E = Existing, C = Existing -> B = Existing
F = Existing -> E = Existing
C = Existing, B = Existing -> E = Existing
F = Existing -> B = Existing
B = Existing, A = Existing -> C = Existing
F = Existing, B = Existing -> E = Existing
F = Existing, E = Existing -> B = Existing
D = Existing -> A = Existing
C = Existing -> A = Existing
E = Existing, A = Existing -> B = Existing
I want to buid a query that has two or more items on the left of the rules, example: E = Existing, C = Existing -> B = Existing
->I want to buid a query to predict that: when a customer buy 'E' and 'C' then he likely buys 'B'

hi,
Is it possible to use two algorithms together?I need to write prediction Query so that its should both models having clustereing algorithm and timeseries algorithm.
for example
I am having student information.I ve to predict performance of students for certain period.The students should be classified by their types like rich kids,poorkids..like that.I need to predict the performance of the rich kids??
can anyone help?

Dear friends,
I'm reading Wiley's Data mining with SQL Server 2005... There are MANY things I can't understand about MovieClick example (Chapter 3).
I hope someone is going to help me with this troubles...
WARNING (1): I'm a dummy both with sql server and data mining.
WARNING (2): My English is not good at all.
Just two questions for now:
1) When I create the model to predict the number of bedrooms for homeowners, the book says to check BEDROOMS as Predictable... question: is it also an INPUT for the model, or PREDICTABLE only?
2) I'd like to keep this model (number of bedrooms.......) and make a prediction query.
- Query builder
- select case table -> Homeowners
- Drag the Customer ID column from the Homeowners table and drop it on the grid
- Drag the BEDROOMS column from the mining model and drop it on the grid.
- On the last row: Source=PredictionFunction, Field=PredictProbability
- Drag the BEDROOMS column from the mining model and drop it into Criteria/Argument
- Add (i.e.) 'Two or Three' to the field Criteria/Argument
I execute the query and I obtain many rows in a table with the following colums: CustomerID, BEDROOMS and Expression: WHAT DOES THIS MEAN?
WHICH INFO DO I GET FROM THOSE NUMBERS? WHAT CAN I LEARN FROM THEM?
Thanx a lot in advance, please help me!

I am doing this right now this way:
1) I do the DMX prediction query where I get the PredictNodeId(predict_var), my query is like this:
SELECT PredictNodeId(predict_var), model_1.predict_var, t.var_1, t.var_2 FROM model_1 PREDICTION JOIN OPENQUERY([DATA_SOURCE_1], 'SELECT var_1, var_2 FROM table_1') AS t ON model_1.var_1 = t.var_1 AND model_1.var_2 = t.var_2
2)I do the DMX query to get the node_description from the model.content iterating each row from the result of my prediction query, this query is like this:
SELECT node_description FROM model_1.content WHERE node_name = 'node_name_var'
In this query node_name_var = PredictNodeId(predict_var) from my prediction query.
What I want to know if there is a way to merge Query 1 and Query 2 so I can get the node_description in the same query qhere I get the PredictNodeId.
Thanks

Can anyone show me how to run a prediction query and save the results to a sql table without using the T-SQL OPENQUERY tip here http://www.sqlserverdatamining.com/DMCommunity/TipsNTricks/3914.aspx? I am looking for an example in vb.net that I can use in a SSIS script task.
Thanks
