Some General Questions About The Managed Plugin-Algorithmn Wrapper
Dec 31, 2007
Hi,
After I've written my first Plugin-Algorithmn, I have some general questions about the Managed Plugin-Algorithmn wrapper.
What does the Property "support" express in view of predictions? Is it the overall number of cases the found rule works for?
What's the difference between AdjustedProbability and Probability ?
There is a probability for a specific StateStatistic and one for the whole AttributeStatistic.
What does the latter one express? Perhaps the overall probability that the discovered rules will lead to correct results for this attribute ? Let's say I have two rules for an attribute. Rule A has a probability of 0.5 and Rule B has a probability of 0.66. What would be AdjustedProbability.Probability in the case? The mean of 0.5 and 0.66 ?
I spent the last days programming a managed datamining plugin-algorithmn for SSAS 2005 and have troubles with the Prediction-Method.
Die Prediction-Methode of the "Shell-Algorithm" leads to an error-message on execution of the prediction-query (Internal Error: Unexprected Error ... dmxpredict.cpp Row 205 ...).
Can anyone provide me with a very simple implementation of this Method which just says that for every output-attribute the first (discrete) state should be predicted with a probability of, let's say, 90 % ?
Maximum Number of rows allowed in sql server 2005 tables ? Maximum Number of columns allowed in sql server 2005 tables ? What are all the built in string functions can be allowed for 'TEXT' DataType in sql server 2005?
New to using databases that are NOT Access. New to MS SQL Server. I'dlike help understanding some concepts.Firstly, I'd like to know how to connect to a database using MS SQLServer on a remote web server using Windows XP; I know the IP and havethe username and password to connect...but what program do I use?Suggestions, appreciated.Secondly, I'd like to make changes to the remote database - anyonesuggest programs to use?Regards,OZ
I asked my tutor those questions and I want to ask you too
Hi Sir
I hope you doing fine
I have some questions please;
What is the diffrent between For Attach in Create Database Command and Sp_Attach_DBWhat is the diffrent between store db file in folder and store it raw partition e.g. C:What is the useful from TextImage_On in Create Table Command; it is order Sql Server to stor the photo in diffrent table's fileCan you give us a basic steps to insert *.JPG photo in Sql ServerIf I have this statement:
Why This Code not works and how can I do this without using Triggers.
Can you tell us the different between Media Set and Media Family and the useful of them. Can we do Backup and Restore Commands on Virtual Tape and How?When I write this code
Create Trigger xTrig on xTable For Insert AS
When this trigger will fire Before Insert, during or after.
What is the useful from EDURE in Create ProcedureWhat is the useful from Recompile in Create Procedure In Sp_AddRole how can I create this role and make the owner anther person e.g. sa What is the different between User and LogIn in Sql ServerWhat is the different between Role and Group in Sql ServerWhy can I add user to group in Sp_AddUser and I could not add one in Sp_AddLogin
These lies work good
-- Add New LogIn to ProgramManagerRole
Exec Sp_AddLogIn 'zProgramManagerUser' , '' , 'C8_Ahmad_13430_NewSIS' , 'English' Go
hiI just gotta know:what is the database that sql server creates/works with?Can it be used in an oracle environment?Or can it be uploaded to a Oracle db? (like access thru odbec)thanks!!jim
A couple questions about SQL Server Reporting Services: 1. Can it be used for other data sources besides SQL Server (Oracle db, XML files, via APIs, etc.)? 2. Can it do ad hoc reporting? I like the "universes" that the SAP Business Objects product allows. Does Reporting Services have something like this, to provide a simplified view that non-technical business users can use to create their own reports? Or is Reporting Services just the equivalent to Crystal Reports?
(I wanted to post this in the general MSDN forum for SQL Server, but I can never log in there for some reason.)

It states pretty clearly in the documentation for the Microsoft.SqlServer.Dts.Runtime.Wrapper namespace that "This assembly is a Primary Interop Assembly (PIA) for the namespace Microsoft.SqlServer.Dts.Runtime, which is the assembly Microsoft.SqlServer.ManagedDTS (in microsoft.sqlserver.manageddts.dll). The classes in this namespace should not be instantiated. Instead, use the classes found in the Microsoft.SqlServer.Dts.Runtime. "
And yet as I have found out earlier today and talked about here, sometimes it is absolutely necassary to use Microsoft.SqlServer.Dts.Runtime.Wrapper. Why is this? Why is there no class in Microsoft.SqlServer.Dts.Runtime that allows me to access the specific connection managers rather than using the generic ConnectionManager class?
How Can I Generating wrapper code for SQL Server Stored Procedure ??
If You will Go To The Following link you will see an example for Generating wrapper code for Oracle Database .. And Also the author say there is built in tool for Generating wrapper code for SQL Server http://www.codeproject.com/vb/net/OracleSPWrapper.asp my question .. where is this tools ???
Using SQL Server 2000...I wrote a wrapper to call a sub proc (code provided below). Theintended varchar value returned in the output parameter of each procis a string implementation of an array.(The string separates elements by adding a period after each value.e.g. 1. 2. 3. 4. 5. etc., although my simplified example only createstwo elements.)My vb.net calling code parses the returned string into individualelements.I TESTED BOTH PROCS FIRST:The wrapper returns 'hello' when I test it by insertingSELECT @lString='hello'before the GO, so I believe it is called properly.The sub_proc returns the "array" I want when I call it directly.THE PROBLEM: When I call the wrapper, and expect it to call sub_proc,it returns a zero.In fact, when I assign a literal (like 'hello') to @lString insub_proc, 'hello' is not returned.So the wrapper is not calling the sub_proc, or the sub_proc is notreturning an output value.OR...I have read about some issues with OUTPUT string parameters beingtruncated or damaged somehow when passed. I doubt this is theproblem, but I'm open to anything.I want to use the wrapper because, when it's finally working, it willcall several sub_procs andreturn several output values.Any thoughts? Thanks for looking at it! - BobThe Wrapper:-----------------------------------------------------------------CREATE PROCEDURE wrapper@lString varchar(255) OUTASEXEC @lString = sub_proc @CommCode, @lString OUTGO-----------------------------------------------------------------The subordinate procedure:-----------------------------------------------------------------CREATE PROCEDURE sub_proc@lString varchar(255) OUTASDECLARE @var1 int,@var2 intSELECT @var1 =(SELECT count(mycolumn)FROM mytableWHERE condition=1)SELECT @var2 =(SELECT count(mycolumn)FROM mytableWHERE condition=2)/* If @var1 returns 5 and @var2 returns 7, Then @lString below wouldbe "5. 7." */SELECT @lString = STR(@var1) + '.' + STR(@var7) + '.'GO-----------------------------------------------------------------
I am currently trying to create a Script Task which reads in a file containing meta-data which then dynamically creates a Flat File Connection Manager and configures it using this meta data. After perusing various newsgroups and articles, it seems that I need to be able to reference the Dts.Runtime.Wrapper to do this. I have tried using the Add Reference dialog, but it does not contain a reference to this namespace. I can reference this namespace from a "Script Component" but I am unable to reference it from a "Script Task". Is this a known issue or am I just not doing something correctly? If anyone could give me any pointers it would be greatly appreciated. Thanks!
I'm here once again asking for help. Here's my problem:
I have a table that I use in my text mining clustering third-party algorithm. The table is as follows:
ID: primary key (int)
ID_DOC: an ID I use to know from what document a term came from (int)
ID_TERMO: the term ID (int)
TERMO: the term itself (varchar(max))
FREQ: the term frequency, usually TFxIDF (real)
Alright... I need the term itself to do some visualization. What I want to do is to get each case's term and store'em on a vector<char*>. So I did some changes on the ProcessCase method. In this method the data (each variable of the case) can be accessed rolling over the case using a DM_STATE_VALUE* as follows:
DM_STATE_VALUE* xpto = (DM_STATE_VALUE*) rgValue;
for(unsigned int i=0;i<_cAttribute;i++) { // _cAttribute is the number of variables
double aux = xpto.r8;
//Do some calculation using aux
}
Alright... It works quite well when I only have real and int data types on the database. But how the get the term collumn (varchar(max)) ?
How to modify the DM_STATE_VALUE union to accept strings as well ?
I want to create a Data Mining Plugin-Algorithmn that uses existing mining models in the current DB. Is there a way to get a AdomdConnection from within an (Managed) Plugin-Algorithmn? This Connection should point to the current SSAS-Database.
I have a code for Nearest neighbour algorithm, I want to build a datamining algorithm using that code..
I have the following link that includes the source code for a sample plug-in algorithm written in C#.
(managed plug-in framework that's available for download here: )http://www.microsoft.com/downloads/details.aspx?familyid=DF0BA5AA-B4BD-4705-AA0A-B477BA72A9CB&displaylang=en#DMAPI.
But i am confused on where to insert my algorithm logic?
as we know we get clustering algorithm with managed plugin algorithm API
does anyone have developed any other plugin algorithm as i want to check what are the things that needs to be modified. i am not data mining algorithm developer but i just want to check where we have to make changes. i would be better if i get source code for algorithm other than clustering
I'm following the steps of the tutorial on how to construct a managed data mining plugin in C#.
Once created the Metadata, Algorithm and Navigator classes I tried to register it on Analisys Service by running the XMLA template written on the tutorial but I got the following error:
Unable to retrieve a list of supported data mining algorithms. Make sure you are connected to the correct Analysis Services server instance and the Analysis Services server named localhost is running and configured properly. You can continue with a default list of data mining algorithms
The GUID in the XMLA is correct as so the service name. The SQL Server engine runs fine.
I noticed that when I run this XMLA, the file msmdsrv.ini is modified, so in DataMining/Algorithms session a new entry is correctly created, enabled and the GUID is also set correct.
I also tried to ignore the XMLA setting up msmdsrv.ini manually but it also didn't work.
The build process is fine, both DMPluginWrapper and the Shell are registered by gacutil and I restarted (also try to stop and start) the server.
I've developed a clustering plugin for SQL Server 2005 but now I want to port the .dll so my algorithm can run on another machine. Both machines have SQL Server 2005 installed, but different versions of Windows.
What are the steps I need to follow to port the plugin ?
I am working on an AS Algorithm Plugin . I want to debug it in the AS Server, but I cant figure out how it works. Now I every time install and deploy the plugin, but if I catch an exception, it just shows me the message, not the stack trace. Anyone, something friendlier method?
hello,everyone,I also met a problem. I stoped the SQL Server Analysis Services first, and registered the GAC successfully, then modified the msmdsrv.ini manually.In fact,I found the format of my msmdsrv.ini is diffirent from the one mentioned in the tutorial,it just like below:
when i restarted the the AS, some error information displayed in event viewer, " can't load MyCompany_Mamaged_Plugin_Algorithm data mining Algorithm provider(ProgID, can't create Algorithm Provider program for MyCompany_Managed_Plugin_Algorithm, ProgID does not exist in the server configuration file"
I am confused by it and have not any idea to solve it. some one can give tips? thanks.
We have a large number of SPs in our databases and decided it was time to get some source control. I have VSTS team explorer installed and working in visual studio, but I cannot get the plugin for SSMS to work - it just says none in the current source control plug-in dialogue box - nothing when I drop it down either.
I'm doing a custom clustering plugin for text to pre-process ("clean" the texts), calculate weights, estimate the number of clusters (using the PBM index) and finally, do the actual clustering.
So... I've made each of these modules on C++ and I'm putting them all togheter on the plugin.
My database (MDB file) has only one table, with only two fields within: a key (auto-incremental) and a small text. What I intend to do is to get the text in each test case, store them togheter somewhere and call my classes to cluster these texts.
I'm trying to log the texts in a file (just a test) on the ProcessCase method, in the CaseProcessor class. I've did it with no problems with numerical data.
But when I load the MDB file on the Mining Structures Wizard, it says the content type of the field holding the texts is "Continous" and the data type is "Text". Actually, when I saw it I didn't really mind.
But when I run the mining model it gives me the following error: "Error 1 Error (Data mining): The data type of the Table1.Texto mining structure column must be numeric since it has a continuous content type (Content is set to Continuous or Key Time or Key Sequence). 0 0 "
So... How do I change this content type ? (the content type combobox on the Mining Structures Wizard couldn't the changed)
Well... As I said in other topics, I'm doing a clustering plugin for text mining. I'm facing many problems and, with your help, solving them one by one.
First of all, thanks a lot again.
Well... I've made a clustering function that is actually working very well. But I'm exporting its results to a log file I use as an algorithm trace for debugging.
My clustering method returns a vector containing information of what cluster each register belongs. For instance:
vector[0] = 1 -> The register of index 0 belongs to cluster 1.
vector[1] = 9 -> The register of index 1 belongs to cluster 9.
vector[2] = 2 -> The register of index 2 belongs to cluster 2.
...
And so on.
But... I know that none of the Navigation methods receives a structure like this one discribed above. I only use it to log the results to debug the algorithm.
But how to pass this information (what register (or test case) belongs to what cluster) to the Navigation ?
Thanks a lot again, and any help will be very appreciated.
Hello people :-)I'm doing some development work with Visual Studio 2005 and SQLServer 2000. My SQL DB is running on a Windows 2000 Server box in the office, and I'm doing the development on my XPPro workstation. Now I've been trying to connect to the Win2000 box though VS and although I can see the server and the DB when I hit ok I get this error"The SQL server specified by these connection propertise does not support managed objects"What the heck does that mean?any help would be great :-)
I have a SQL Server project in Visual Studio 2005 which deploys an assembly to SQL Server 2005 containing various stored procedures user defined functions. Is there any way to tell Visual Studio to drop/create the stored procedures in a schema other than dbo?
ie: User.ChangePassword instead of dbo.ChangePassword.
In VS 2003 I used SQLDMO (Com Object) to list all available SQL Servers. Is in SQL Server 2005 a managed .net Component that can do that task?Thanks,Rainer.
Can anyone explain why when I look at table using enterprise manager, highlight a table, all tasks, maanage indexes why only 1 index appears and when I look at the same table in sysindexes is says that there are 8 indexes. This is the sql code I executed: select object_name(id), indid from sysindexes where object_name(id) = 'tbh_matter_summ'
Is it possible that there is a problem with the database?
I have an MDS entity which will be managed in excel. I do not want the user to enter the Code and Name so I have configured code to auto generate and name to default to another attribute value. I have then hidden code and name in excel.
When I use excel and enter the attribute and publish, the name column is blank in the MDS table.Am I missing something here with the defaulting?The Action is defined as 'Name Defaults to Country'. Where Country is the attribute I am populating.
