hey everbody,
i'm absolutely new to any sort of data management
here it goes: suppose we store 100 .txt or .doc files in sql server and we want that none of the files data should match more than 60%: the question which arises are
1. how do we store files in ms-sql (binary format or normal text)?

Hello,
I am kind of new to Sql Server 2005.
I figured out how to use the import data wizard to import a delimited text file.
But I need to find a way to import many delimited text files at once.
does anybody know if this can be done in Sql Server 2005? and how?

Hi, all here,
I am wondering where can I store my mining results in data mining engine? For example, I got mining results like accuracy chart, decision trees, and other formats of results based on different mining algorithms I used for my data mining, so where can I actually store the results for reporting service use later? Is it possible to do that in SQL Server 2005?
Thanks a lot for any help and guidance in advance.

Hi there,
I have read about SQL Server Integration Services and that they also provide Text Mining service. I have looked at one of the tutorials but it seems that the thing that I want is not there. I want the following:
I want to develop a domain-specific knowledgable system that reads some unstructured data related to the domain. Then, when I query it will provide the most candidate results from these documents ranked by the most appropriate to the least (if the answer is there).
Please let me know if you beleive that I still can use SQL Server integration Services to implement this scenario. Otherwise, if you have any other resourse, like SDK, that can help me please let me know as well.
Regards

Hi,
Somewhere in the literature surrounding SQL Server 2005 DM, I saw a reference to a project that collected and mined RSS data.
Does such a project exist?
Thanks,

Hi!
I have some questions regarding text mining in Microsoft Data Mining Add-Ins for Office 2007.
What do I need to use data mining (especially text mining) through the Microsoft solution?
I guess I need the following:
1) Microsoft Office 2007 (or Microsoft Excel 2007) [does it work with Microsoft Office 2003?]
2) Microsoft SQL Server 2005 [is it possible to use the text mining tool in Excel without access to the SQL Server? For example to directly analyze text data from an Excel worksheet]
3) The Microsoft Data Mining Add-Ins for Office 2007 (which is free of charge?)
What can I do regarding text mining?
1) Is it possible to analyze text data in different languages? [For example French, Swedish, Portuguese, Spanish text; i.e. other languages then English.]
2) Can I count how many cells that contain a specific phrase or a specific word?
3) Can I count how many cells that contain a specific phrase or a specific word given that it fulfill a specific criterion (e.g. given that it has a specific word in another column)?
4) Has the add-in a good options to aggregate words which are synonyms, or miss spelled, in relation to a specific key word?
4) What are the advantages and disadvantages to use the Microsoft solution in comparison to Clementine from SPSS or SPSS Text Analysis for Surveys?
BR,
Dr. Magnus

I have text data files from a third party and they use comma as field delimiters and enclose the text for each column in double-quotes. Not a problem for most of the data files until they start sending files where there is " within the column values. SSIS package fails with the error:
The column delimiter for column "Column 1" was not found.
Any ideas on how to resolve this issue will be greatly appreciated.Thankspcp

Unfortunately, the tutorial is for the Beta version, and therefore there are major differences from the Beta to the current version. The steps can be used as objectives to accomplish.
1). The last page of the tutorial (item 7), Deployment data mining models - Not covered in this tutorial at this moment. What needs to be done in the deployment?
2). The Decision Tree in my project has one node, how would I make the tree show up?
3). My data results are not consistent with the tutorial? Would the software modifications since Beta be the reason?

Hi, all,
Just found that we are not able to define multiple key columns for a mining structure in SQL Server 2005 Data Mining engine, just wondering is there other way to define multiple key columns for a mining structure there? As in many cases, the table we are mining are with composite key consisting of different foriengn keys, e.g. A fact table are with transaction information and other foreign keys. If I am not able to define these composite key here for this fact table, I will have to have a named calculation in data source view to have a key column which is based on these original composite keys? Is this a better way to solve this problem or there is any other alternatives to figure it out?
Hope my question is clear for your help and I am looking forward to heaing from you shortly for your kind advices and help and thanks a lot in advance.
With best regards,
Yours sincerely,

I have a requirement where in i have around 15 different flat files , filenames are fixed but folder path can be changed(i think i should use a variable for folder path). These 15 files data should go to their respective tables in the database.
Whether I need to create separate data flow task for each file or separate package? In addition to these, example : while importing product data into product table, if product ID already exists, we need to ignore it and upload only the new records.

I have a couple of hundred flat files to import into database tables using SSIS.
The files can be divided into groups by the format they use. I understand that I could import each group of files that have a common format at the same time using a Foreach Loop Container.
However, the example for the Foreach Loop Container has multiple files all being imported into the same database table. In my case, each file needs to be imported into a different database table.
Is it possible to import each set of files with the same format into different tables in a simple loop? I can't see a way to make a Data Flow Destination item accept its table name dynamically, which seems to prevent me doing this.
I suppose I could make a different Data Flow Destination item for each file, in the Data Flow. Would that be a reasonable solution, or is there a simpler solution, or should I just resign myself to making a separate Data Flow for every single file?

Hi, i'm trying to do a full text search on my site to add a weighting score to my results. I have the following database structure:
Documents: - DocumentID (int, PK) - Title (varchar) - Content (text) - CategoryID (int, FK)
Categories: - CategoryID (int, PK) - CategoryName (varchar)
I need to create a full text index which searches the Title, Content and CategoryName fields. I figured since i needed to search the CategoryName field i would create an indexed view. I tried to execute the following query:
CREATE VIEW vw_DocumentsWITH SCHEMABINDING ASSELECT dbo.Documents.DocumentID, dbo.Documents.Title, dbo.Documents.[Content], dbo.Documents.CategoryID, dbo.Categories.CategoryNameFROM dbo.Categories INNER JOIN dbo.Documents ON dbo.Categories.CategoryID = dbo.Documents.CategoryID
GOCREATE UNIQUE CLUSTERED INDEX vw_DocumentsIndexON vw_Documents(DocumentID)
But this gave me the error:
Cannot create index on view 'dbname.dbo.vw_Documents'. It contains text, ntext, image or xml columns.
I tried converting the Content to a varchar(max) within my view but it still didn't like.
Appreciate if someone can tell me how this can be done as surely what i'm trying to do is not ground breaking.

I am trying to restore multiple .bak backup SQL database files onto a new server. However, I have found that it will not allow me to restore multiple databases at once. Is there a way to do this so that I do not have to manually upload one at a time? I tried adding all the .bak files at once to the backup device window but it only did the first one listed. It would be so much easier to restore them all at once so that I do not have to continue this manual process. I am restoring them via device.

I need to be able to bulk insert a bunch of tables from their corresponding flat file. I have created an XML file (see below) which has the file name/table name pair at each node. I then created a ForEachLoop task and used the Node enumeration type and the following OuterXpathString: ReferenceFiles/File. At this point I get lost. How do I pass the 2 inside node values (file name and table name) to variables which I can then use as expressions for the bulk insert task inside the Foreach?
Here is XML file:
Code Snippet
<ReferenceFiles>
<File>
<FileName>Ref_Categories.txt</FileName>
<TableName>Ref_Categories</TableName>
</File>
<File>
<FileName>Ref_Configs.txt</FileName>
<TableName>Ref_Configs</TableName>
</File>
</ReferenceFiles>
Thanks.

I used the data export wizard to export a single table to a single flat file (multiple wasn't allowed). I saved the package as a *.dtsx file which I'm attempting to edit to add the additional tables.
Creating additional sources is fairly easy copy of the first source and change to the table name.
I've tried copying the destination connection and changing to a new text file, but can't get past having to add each column manually to the new destination.
How can I duplicate the mapping that must be taking place in the wizard in the *.dtsx editing environment?
This seems like a simple / common task, but I've been unable to find a solution.
Thanks, Richard

Hi gurus,
I've created a linked server (and set up the corresponding schema.ini file) in order to perform bulk-inserts from some CSV text files into SQL tables (from my standpoint the text files are just for reading purposes). The linked server works fine (I can select the data in the files without a problem).
Now the question: is possible to automatically detect when one or more of those files change in order to start the import process automatically? Something like having a trigger created on the CSV files Or there's no easy way to do that so I have, to say something, to create a Job that periodically checks if the files have changed programatically (say, recording each file's timestamp everytime is imported and comparing the recorded value with the current one, or whatever)?
Thanks a lot in advance!

I am using BI Dev Studio for SS2005 in a research (as opposed to a production) environment. Often I want to compare the results of multiple models using the same attributes. If I switch to a different model, the Design view completely resets. Is there any way to retain the same field names with different models in the Design view?
My current workaround is to give my models similar names with AR, DT, CL, LOG, NN suffixes and make global changes in the DMX.
I have consulted the following without finding an answer:
http://msdn2.microsoft.com/en-us/library/ms178445.aspx

Hi,
I have searched but not found quite the best way to look at this so far..
I have an application that outputs data to several text files (up to 30). These have commonality by an object name, but then contain completely different column data.
In DTS I had each of the source text file connections going to one OLE DB connection and then individual transform data tasks pointing to the one OLE DB connection.
Looking at SSIS, it would appear that I would need to have one source and one destination for each of these and therefore 30 parallel data flows?
Just wondering if there is a neater way of doing this??
It is a regular data import that happens a few times a day - the text files are named the same as the SQL tables - ie app_userdata.txt goes to app_userdata table.
Hope that explains ok and thanks in advance.
Mike

I am trying to write (my first, unfortunatly) DTS, and am having some problems.
I need to be able to import multiple flatfiles (all in the same format, just with different schema), each one going into a different table. I have written an application to call my DTS, sending it variables for the tablename and the filename. This works fine when I test it on a single flatfile.
My problem is, the Tranformation object does not reset after each DTS call, so I get "Column does not exist" errors after the first successful import. I can go into the DTS Manager and reset the Transformation options, but that would defeat the purpose of automation. Is there anyway to reset, or another technique, the Transformation object so that it will continuosly work on files that use different schema?
I am very new at DTS, so please consider me "ignorant" when replying.
Thanks in advance.

Hi,
I have just run a simple data set through a model to predict a simple true or false value (i.e. binary output)
The Lift Chart/Mining Legend in Analysis Services shows three results €“ Score, Population Correct (%), and Predict Probability (%)
Population Correct I beleive is the percentage of predictions it got right out of the total number of predictions it tried to make. Is this correct?
However, I can€™t work out how the other two are derived in particular the 'SCORE'. To give a live example the scores were as follows:
Model Score Pop Correct Pred Probability
Decision Trees 0.83 76.59% 54.28%
Neural Network 0.75 67.63% 50.05%
Ideal Model 100.00%
Can anyone help with this and give a detailed explanation?
Many thanks,
S Rajput

Hi,
I am trying to model data in analysis services with the Advance Create Mining Model function in the excel addin. I am having trouble creating an association model that works like the Associate button above the Advanced button.
The format of my data is like this
OrderID Product
100 Bike
100 Helmet
100 Shoes
200 Helmet
200 basketball
200 Bat
300 Shoes
300 Socks
The associate button works perfectly since it asks me which column is the transaction id (orderid) and which column I am trying to predict (product). The advanced create mining model asks me to determine what the columns are...
OrderID=key Product=Input+Predict?
When I run the advance create mining model associate, I get a browser that gives me no rules and the support for only one item itemset (each product but no combination of products).
Does anyone know what I have to do to get it to work like the associate button?

Dear friends,
I encounter a serious problem.
I would like to develop an application that can create Data Mining structures and a mining model in SQL Server 2005 with VB.NET. I tried the code from book Data Mining with SQL server 2005 in chapter 14 but did not work. Any good idea?
Please help me.

Thank you very much for your help.
The errors that I can see in the code that you gave in your answer are the following and they are more or less the same as I had previously
I tried the code but initially I have encounter the following problems.
1. In any line that have the declaration As Server, As Database like in
Public Function CreateDatabase(ByVal srv As Server, ByVal databaseName As String) As Database gives me the problem that type Database is not declared the same type Server is not declared and it does not give me any option.
2. In addition to that for As DataSource, As RelationalDataSource, As RelationalDataSourceView, As ScalarMiningStructureColumn, As DataSourceViewBinding, gives me the problem that type is not declared.
3. Finally in mc = New MiningModelColumn("Yearly income", Utils.GetSyntacticallyValidID("Yearly income", Type.GetType(MiningModelColumn))) is not accesible in this context because it is 'Private'.
I have some more problems but I thing that by solving the above that I referred I will solve the rest.
Thank you any way.
Best regards,

I perform data mining on all products and a specific product category.
Do I need to create 2 data source views, one for all products and the other one for the specific product category?
Afterward, I run the Data Mining Wizard 2 times to create 2 mining structures.
I also need to add the same mining model (e.g. Bayes, Cluster) to each of these mining structures.
Is there any simple way to do it?
Thanks.
Joe.

I was asked at work to create an audit log to track user changes to our SQL Server 2005 database. My plans were to use a trigger to store the changes in a database table. I was just told that rather then storing these changes the database, that I should write these changes to a text file. I am having problems finding a good example of how to write to a text file in T-SQL. Does anyone have an example of how to do this? Thanks
