Why I Got The Message As You Need To Create The Many-to-one Relationship Between The Case Table And The Nested Table?

May 30, 2007

Hi, all experts here,



Thank you very much for your kind attention.



I am trying to create a new mining structure with case table and nested table, the case table (fact table) has alread defined the relationships with the nested table(dimension table), and I can see their relationship from the data source view. But why the wizard for creating the new mining structure showed that message? Why is that? And what could I try to fix it?

Hope it is clear for your help.

Thanks a lot for your kind advices and I am looking forward to hearing from you shortly.

With best regards,

Yours sincerely,

Jun 18, 2007

Hi, all experts here,



Thanks for your kind attention.



I want to use time series algorithm to mine data from my case table and nested table. Case table is Date table, while nested table is the fact table. E.g, I want to predict the monthly sales amount for different region (I have region table related to the fact table), how can I achieve this?

Thanks a lot and I hope it is clear for your help and I am looking forward to hearing from you shortly.

With best regards,

Case && Nested Table Selection And Errors

Aug 31, 2006

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.

regards

Case Table And Nested Tables Design Problem

Oct 20, 2006

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

Case Table And Nested Tables In Association Algorithm

Aug 30, 2006

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.

Create Table With Recursive Relationship

May 16, 2006

I am fairly new to SQL and I am currently trying to createa SQL table (using Microsoft SQL) that has a recursiverelationship, let me try to explain:I have a piece of Data let's call it "Item" wich may again contain onemore "Items". Now how would I design a set of SQL Tables that arecapable of storing this information?I tried the following two approaches:1.) create a Table "Item" with Column "ItemID" as primary key, somecolums for the Data an Item can store and a Column "ParentItemID". Iset a foreign key for ParentItemID wich links to the primarykey"ItemID" of the same table.2.) create separate Table "Item_ParentItem" that storesItemID-ParentItemID-pairs. Each column has a foreign key linked toprimary key of the "Item" Column "ItemID".In both approaches when I try to delete an Item I get an Exceptionsaying that the DELETE command could not be executed because itviolates a COLUMN REFERENCE constraint. The goal behind these FK_PKrelations is is that when an Item gets deleted, all childItems shouldautomatically be deleted recursively.How is this "standard-problem" usually solved in sql? Or do I inned toimplement the recursive deletion myself using storedprocedures or something ?

Questions On Key Column In Case Table And Key Time Column In Nested Table Using Time Series Algorithm

Jun 4, 2007

Hi, all experts here,



Thank you very much for your kind attention.



I am confused on key column of case table and key time column of nested table by using Time Series algorithm.

In my case, the case table structure is as below:

Territory key text (the ID is actually dimrisk_key, in this case, I use the name column binding to combine the Territory column of case table Dimrisks),

While the nested table structure is as below:

Cal_month key time (in this case, actually the ID is dimdate_key, again, I used name column bining property to bind the Cal_month to the ID)

So my question is, as the key column of case table has been set to be Territory, as a result, does the model training still cover all the cases (rows) based on the ID of the table?

Also, in the nested table, as the key time column has been set to Cal_month rather than Dimdate_key of the nested table, as a result, would the single series based on the cal_month?



Hope it is clear for your advices and help.

And I am looking forward to hearing from you shortly.



With best regards,



Yours sincerely,

The 3 csv files were successfully imported into the ChemDatabase of my SSMSE.

2 questions to ask:
(1) How can I designate the Primary and Foreign Keys to these 3 dbo Tables?
Should I do this "designate" thing after the 3 dbo Tables are done or during the "Importing" period?
(2) How can I set up the relationships among these 3 dbo Tables?

Please help and advise.

How Can I Create A One-to-one Relationship In A SQL Server Management Studio Express Relationship Diagram?

Mar 25, 2006

How can I create a one-to-one relationship in a SQL Server Management Studio Express Relationship diagram?

For example:
I have 2 tables, tbl1 and tbl2.

tbl1 has the following columns:
id {uniqueidentifier} as PK
name {nvarchar(50)}

tbl2 has the following columns:
id {uniqueidentifier} as PK
name {nvarchar(50)}
tbl1_id {uniqueidentifier} as FK linked to tbl1.id


If I drag and drop the tbl1.id column to tbl2 I end up with a one-to-many relationship. How do I create a one-to-one relationship instead?

Default Table Owner Using CREATE TABLE, INSERT, SELECT && DROP TABLE

Nov 21, 2006

For reasons that are not relevant (though I explain them below *), Iwant, for all my users whatever privelige level, an SP which createsand inserts into a temporary table and then another SP which reads anddrops the same temporary table.My users are not able to create dbo tables (eg dbo.tblTest), but arepermitted to create tables under their own user (eg MyUser.tblTest). Ihave found that I can achieve my aim by using code like this . . .SET @SQL = 'CREATE TABLE ' + @MyUserName + '.' + 'tblTest(tstIDDATETIME)'EXEC (@SQL)SET @SQL = 'INSERT INTO ' + @MyUserName + '.' + 'tblTest(tstID) VALUES(GETDATE())'EXEC (@SQL)This becomes exceptionally cumbersome for the complex INSERT & SELECTcode. I'm looking for a simpler way.Simplified down, I am looking for something like this . . .CREATE PROCEDURE dbo.TestInsert ASCREATE TABLE tblTest(tstID DATETIME)INSERT INTO tblTest(tstID) VALUES(GETDATE())GOCREATE PROCEDURE dbo.TestSelect ASSELECT * FROM tblTestDROP TABLE tblTestIn the above example, if the SPs are owned by dbo (as above), CREATETABLE & DROP TABLE use MyUser.tblTest while INSERT & SELECT usedbo.tblTest.If the SPs are owned by the user (eg MyUser.TestInsert), it workscorrectly (MyUser.tblTest is used throughout) but I would have to havea pair of SPs for each user.* I have MS Access ADP front end linked to a SQL Server database. Forreports with complex datasets, it times out. Therefore it suit mypurposes to create a temporary table first and then to open the reportbased on that temporary table.

What Relationship To Use Between These Two Table?

Feb 7, 2008

Hi I have two tables:
1.) Operator-OperatorID{PK, int, not null}-OperatorName{varchar(100), not null}-Enabled{bit, not null}-PasswordChange{bit, not null}-BirthDate{datetime, not null}
2.) Password-PasswordID{PK, int, not null}-Password{varchar(50), not null}-ExpirationDate{datetime, not null}
I'm not sure how to design and layout these two tables. The layout of these two tables is completely flexible as the application has not been deployed. I'm open to any good suggestions.
For each Operator I want to stored up to 3 previous passwords plus their current password. The password change field is so that if the operator's password expires or gets reset, they will be forced to enter a new password. This is a simple internal company application, so password encrypting is not necessary. The ExpirationDate indicates the date that the password will expire.

Hope to hear from someone soon! Thank you!

Create Table From Text File, Extract Data, Create New Table From Extracted Data....

May 3, 2004

Hello all,

Please help....

I have a text file which needs to be created into a table (let's call it DataFile table). For now I'm just doing the manual DTS to import the txt into SQL server to create the table, which works. But here's my problem....

I need to extract data from DataFile table, here's my query:

select * from dbo.DataFile
where DF_SC_Case_Nbr not like '0000%';

Then I need to create a new table for the extracted data, let's call it ExtractedDataFile. But I don't know how to create a new table and insert the data I selected above into the new one.

Also, can the extraction and the creation of new table be done in just one stored procedure? or is there any other way of doing all this (including the importation of the text file)?

Any help would be highly appreciated.

Thanks in advance.

Table Relationship. What Am I Doing Wrong?

Feb 27, 2008

Hello,

I have 3 tables: Articles, ArticlesTags and Tags.
ArticleTags relate Articles and Tags records.

When I try to delete a record in Tags I get the following error:

The DELETE statement conflicted with the REFERENCE constraint

"FK_ArticlesTags_Tags". The conflict occurred in database "MyDB", table "dbo.ArticlesTags", column 'TagID'.
The statement has been terminated.

What am I doing wrong?

Here is how I am creating my tables:

create table dbo.Articles
(
ArticleID uniqueidentifier not null
constraint PK_Article primary key clustered,
Body nvarchar(max) not null

)
create table dbo.ArticlesTags
(
ArticleID uniqueidentifier not null,
TagID uniqueidentifier not null,
constraint PK_ArticlesTags
primary key clustered (ArticleID, TagID),
constraint FK_ArticlesTags_Articles
foreign key(ArticleID)
references dbo.Articles(ArticleID)
on delete cascade,
constraint FK_ArticlesTags_Tags
foreign key(TagID)
references dbo.Tags(TagID)
)
create table dbo.Tags
(
TagID uniqueidentifier not null
constraint PK_Tag primary key clustered,
[Name] nvarchar(200) not null
)

Basically, what I need is:

1. If an Article is deleted then:
> Delete all records for that Article in ArticlesTags
> Don't delete any Tag in Tags.

2. If an Tag is deleted then:
> Delete all records associated with it in ArticlesTags.
> Don't delete any Article in Articles.

What am I missing?

Thanks,
Miguel

Table Relationship In VB Express

Dec 19, 2006

I
have 3 tables I am trying to relate for a music player. I was
following the example in the msdn however, my relationships do not seem
right. Here are tables i want to relate:

Table 1:
ArtistID
ArtistName:

Table 2:
RecordingID
RecordingName
ArtistID

Table 3:
TrackID
TrackName
TrackNumber
TrackLocation
RecordingID

So
the main idea here is that the foreign keys are recordingId and
artistID. So what i did is created the 3 tables and then make a
diagram to create the relationships. I then was reading this post:

http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=219696&SiteID=1

What
i want to do is use 2 different text boxes lets say and as i move from
the records in the Record_table (2) the corresponding artist will
change with it. However in the dataset the relationship looks like
this:
Artist -> Recording -> Track.... inorder for me to get
this relationship to work correctly i have to change all the
relationships in the dataset diagram. This way the dataset would look
like this: Track -> Recording ->Artist. This way i can use the
2 bindings to reference each other as stated in the link above. why
doesnt the relationship of the database know this already? why do i
have to change the relationship in the datasets.

Search On Table With Recursive Relationship

Apr 15, 1999

I am using tables with recursive relationships extensively. For example the table tbComponent has a primary key called Co_ID and a foreign key called Co_Co_ID which references the field Co_ID. This allows a component to have unlimited child components, and each child component can have an unlimited number of tiers of children. I have a few question for which I have seen no documentation on.

1. How can I create a view or a SP that will return a component record and all of its children and children's children records down to the last/lowest child record?

2. I need to be able to do a search in this table. Example:

Table: tbComponent
Columns: Co_ID Integer
Co_Co_ID Integer
Co_Name Text
Co_Attribute Text
Co_Category Text


Note: the data for Co_Category comes from a lookup table with also has a recursive relationship to itself where a category can have an unlimited number of tiers of children categories.

A typical group of records could be something like this:


Co_ID Co_Co_ID Co_Name Co_Attribute Co_Category

1 1 Car Blue Ford
2 1 Body Steel Parts
3 2 Door Front Parts
4 3 Invoice April 1 1999 Accounting

Ok, say there is over a million records in this table. Say I want to query this table and return all of the invoices for cars between March 1 1999 and May 1 1999. Say for example that there are less records where Co_Name has a value of Car then there are records with a value of Invoice, so logically I would set some kind of criteria to limit only invoices with where Co_Name = "Car". That's easy, I can return a result set of all the records Where Co_Name = "Car" and I can hold these in a view or a temp table. Now I need to query this View or temp table and see if it has any children records records Where Co_Name = "Invoice" . The problem is that the Invoice child could be a child record directly under the "Car" record, or 10 levels of children records down. The logic for this would be:

If Co_Name = "Car" Then Select * Where Co_Co_ID = 1, then take all of those record's values in Co_ID and run another statement Where Co_Co_ID = X and so on until there are no more children to search. If any of those records have a value of Invoice in Co_Name then return them.

Please don't give any speeches on Normal Relationship Database design suggesting a typical design using something like a Car table, a parts table, and a invoice table. I used the example above to demonstrate the dynamics of doing a search on a recursive relationship. I understand relationship theory and a recursive relationship is what we need to use in our situation.

Thanks for any and all input!

When To Use A Nested Table?

Jul 19, 2007



Why would someone choose to model a problem with a case and nested table versus just using a case tables with multiple rows?

For example, a simple customer and product scenario where you could say:



Mining Model DT_CustProd
(
[Id] ,
[Gender] ,
[Age]
[Products] Predict
(
[ProductName] ,
[Quantity]
)
)



But you could also model as:



Mining Model DT_CustProd
(
[Id] ,
[Gender] ,
[Age]
[ProductName] Predict,

and just insert multiple rows per Id/Gender/Age? Is there any rule of thumb to use here when deciding to model with a nested table?


I understand that a nested table essentially pivots the data (http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=408840&SiteID=1) and the data becomes an attribute, but how do you know if you want that, or you want the data as a value of an attribute?

Why Use Nested Table?

May 17, 2006

Hi, all here,

I have a question about nested table use. I dont quite clearly see through why the nested table is very much necessary? I mean if we need information from both the current case table and nested table for mining models, we can just join both tables?

Thanks a lot in advance for any guidance and help.
