Hi All,
We're currently preparing for a project for a bank client of ours where we would be using SQL Server 2008's data mining capabilities.
In the context of the out-of-the-box algorithms of SQL08 does the algorithms Logistics, Clustering and Logistic Regression includes Dynamic Logistics, Dynamic Clustering and Dynamic Logistic Regression?

Joseph
dear experts,
i heard in a session, that the tables which are modifying continuously are known as dynamic tables.and which are not are known as static tables.
my question is how to find the statics to judge static and dynamic tables?
I have gotten mixed comments on this topic. I have a 64 bit machine running 64 windows 2003 standard and 64 SQL 2005 standard with 8 GB of RAM. We want to upgrade it to 32 GB. What is the best approach to do this? Dynamic or Stattic giving min and max server memory a value ? and if static what value should I use for 32 GB knowing that this box is only being used for SQL.

View 4 Replies View RelatedIn one step of an SSIS package, i create an outgoing XLS filename based on the current datetime setting, a la:
"myFileName_" + (DT_WSTR,4)YEAR( getdate()) + RIGHT("0" + (DT_WSTR,2)MONTH( getdate()),2)+
RIGHT("0" + (DT_WSTR,2)DAY( getdate()),2) +
RIGHT("0" + (DT_WSTR,2)DATEPART("hh", getdate()),2) +
RIGHT("0" + (DT_WSTR,2)DATEPART("mi", getdate()),2) +
RIGHT("0" + (DT_WSTR,2)DATEPART("ss", getdate()),2) +".xls"
which provides the format as myFileName_yyyymmddhhmmss.xls.
This value is then assigned to a variable, user::myFilenameDateTime.
This variable is referred to in various steps which need the full pathname or filename.
I found, though, that in subsequent steps, the value for user::myFilenameDateTime is re-calculated whenever the variable is invoked.
So in one Task i created the physical output XLS file and named it "correctly", eg, myFileName_20070428090204.xls; in the next Task, i call a Stored Procedure in SQL Server 2005 to email the file with a corresponding message (that pulls in more data from the database).
The single Parameter to the Stored Procedure (that does the emailing) is the supposed/expected full Pathname of the outgoing file just produced but the parameter no longer represents the original filename -- and has changed slightly (a few seconds have been added) and the filename is now, myFileName_20070428090210.xls; consequently, my Email Distribution program cannot find the file with that specific name, although File = myFilename_20070428090204.xls does certainly exist.
so it appears that these variables are calculated realtime whenever encountered.
1) Am I misunderstanding something or misusing the variable assignment?
2) How can i keep << myFileName_yyyymmddhhmmss.xls >>, "static" throughout the duration of the overal SSIS Process.
3) I would think that even if I assign the derived myFileName value initially to ANOTHER "static" variable, this won't achieve anything because the new variable will be re-calculated again, as well, when it is invoked.

Hi every one,
Could you please anyone tell me how to have static and dynamic columns in a matrix?
We can add static columns by right clicking detail text box and add column. But it will repeat for each column group. I need static columns in the dynamic columns level itself.
Thanks in advance!
I need to put a dynamic table (the amount of rows I control) into a static container (with a fixed size).
View 2 Replies View RelatedI'm trying to setup a dynamic ole db connection using the SA user ID, it has to be dynamic because the server name will change and it has to be SA because we're pulling information from system databases that some users don't have access to.
If I setup a regular static connection using SA credentials it works like a charm of course. When I create an expression to use the User:erver variable it doesn't work, it throws an error message saying that "The login failed for user sa" among other things, I'm thiking that the sa's password is not being saved.
Where exactly do I place a password for dynamic connections using sql server users? On the connection string? On the password property of the source? Any ideas?
Hi, all,
Thanks for your kind attention.
Just wonder is there any good idea for us to select attributes for training models? Both for non-supervised algorithms like Association Rules and Clustering etc. and supervised algorithms like decision tree etc.
It will be much interesting to hear from you for any best practices and popular methods of dealing with this issue.
I am looking forward to hearing from you and thanks for your advices.
With best regards,
Yours sincerely,
I'm using Delphi 2006 to create a DLL which will be integrated into SQL 2005. It's been a long road and I've made a lot of headway, however I am currently having the following problem creating the stored procedure:
My dll name is 'Crystal_Reports_Test_01'
In the DLL, my class is named 'Class01'.
In the DLL, my procedure is named 'TestMe'
I've managed to integrate the DLL into SQL using the following statement:
CREATE ASSEMBLY TEST_ERIC_01
AUTHORIZATION dbo
FROM 'c:mssqlassembliescrystalreports.dll'
WITH PERMISSION_SET = UNSAFE
I am attempting to create the stored procedure which points to the 'TestMe' method inside of the DLL. FYI: 'CrystalReports' is the namespace above my class that I had to add in order to get it to locate the class. The following code is used to create the stored procedure:
create procedure dbo.Crystal_Reports_Test_01(
@Parm1 nvarchar(255)
)
as external name TEST_ERIC_01.[CrystalReports.Class01].TestMe
But I get the following error:
Msg 6573, Level 16, State 1, Procedure Crystal_Reports_Test_01, Line 1Method, property or field 'TestMe' of class 'CrystalReports.Class01' in assembly 'CrystalReports' is not static.
I'm not sure what this means exactly. I think it means the method (the procedure) is not using Static method binding but should be. I have no idea what this really means or how to accomplish this in the DLL - or if I'm even going about this in the right way.
Any help would be appreciated ! I'll post the Delphi code (DLL) below.
Thanks,
Eric Gooden
library CrystalReports;uses System.Reflection, System.Runtime.InteropServices;...................type Class01 = class public procedure TestMe([MarshalAs(UnmanagedType.LPWStr)] var sVarString: wideString); export; end;procedure Class01.TestMe([MarshalAs(UnmanagedType.LPWStr)] var sVarString: wideString); export;begin sVarString:= 'Lets change the value and see if the stored proc. gets the change.';end;end.
I have some data in Excel - sheet1 which would be static.
Now I need to import data from SQL Server (using a query) and Union above static data with this SQL data and later I will have to create PowerPivot table in Sheet2.
Which is suitable option for me to import data from SQL to excel as I see "From SQL Server" option under "Data" and "Power Query" tab as well.
How to merge above SQL data with existing static data?

I just want to know what are the data algorithms available for sql server 2005 and can i use data mining as a web service
I am in the stage of design for an application that uses SQL server 2005. We intended to encrypt some sensitve data using the encryption features in SQL server 2005. we will use symmetric key encryption. The question here is which symmetric encryption algorithm has the best performance? how much does the key size affect the perfromance? the data to be encrypted will be some lines of text equal to a word document.
any ideas?
Hello Everyone,
I am reading DataMining Tutorial and right now I am at the Mining Algorithms section. I cannot understand any of the algorithms. For example take the following text... what a bunch of mouthful bla bla bla it is ....
"The Microsoft Decision Trees algorithm supports both classification and regression and it works well for predictive modeling. Using the algorithm, you can predict both discrete and continuous attributes.
In building a model, the algorithm examines how each input attribute in the dataset affects the result of the predicted attribute, and then it uses the input attributes with the strongest relationship to create a series of splits, called nodes. As new nodes are added to the model, a tree structure begins to form. The top node of the tree describes the breakdown of the predicted attribute over the overall population. Each additional node is created based on the distribution of states of the predicted attribute as compared to the input attributes. If an input attribute is seen to cause the predicted attribute to favor one state over another, a new node is added to the model. The model continues to grow until none of the remaining attributes create a split that provides an improved prediction over the existing node. The model seeks to find a combination of attributes and their states that creates a disproportionate distribution of states in the predicted attribute, therefore allowing you to predict the outcome of the predicted attribute"
In the above text what is meant by discrete and continious attributes? what is regression? what is predicted attributes? what are input attributes? what is distribution of states?
Is there a source which explains these algorighms in a easier way ....
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?
Hi,
In the info for SQL Compact Edition 3.5 it states that one of the features is:
Support for newer and more secure encryption algorithms.
I can't seem to find details of exactly what these new, more secure algorithms are. It appears 3.1 used 128-bit RSA. Is this the same in 3.5, or has this changed?
Thanks
Can anybody answer this question ?

Hi, all here,
I am having a question about plug-in algorithms in SQL Server 2005. Since we are able to implement our own algorithms in SQL Server 2005 analysis services architecture, so my question is: what benefits can to a great extent be achieved? Like say, we are going to implement a plug-in algorithm, so what considerations should be concerned?
Thanks a lot in advance for any guidance and help.
Hi, all here,
I am having a more considertaion about Data Mining plug-in algorithms. When we say we are going to embed a uesr plug-in algorithm, so what is the context for that ? I mean in which case then we thing we need to embed a user plug-in algortihm? I know when we say we are going to embed a user costomermized plug-in algorithm, it means we want something more costomized. But what kind of customized features are generally concerned? Is it independant for different market sectors?
I dont think we can just try to embed a plug-in algorithm then compete it with avaialble algorithms to see which one is with better prediction accuracy?
Would please someone here give me some guidances about that?

Hi, all experts here,
Thank you for your kind attention.
Could please any of you give me some advices for if there are tutorials and demos avaiable which cover all the SQL Server 2005 data mining built-in algorithms?
That will be great to hear from any of you shortly. Thanks a lot in advance.

Yours sincerely,
I have the following stored procedure...
CREATE Procedure UserGetInfo2 (@UserID int, @SystemTimePeriodID int )As set nocount onSELECT Users.UserId as UserID, Users.UserName as UserName, Users.RealName as RealName, UserTimePeriod.BudgetCode as BudgetCode, UserTimePeriod.SystemTimePeriodID as SystemTimePeriodID, Users.Password as Password, Users.SSN as SSN, Users.Location as Location, Users.ScheduleType as ScheduleType, Users.EmployeeType as EmployeeType, Users.TimeAccounted as TimeAccountedFROM Users INNER JOIN UserTimePeriod ON Users.UserId = UserTimePeriod.UserIDWHERE (users.userID= @UserID) AND (UserTimePeriod.SystemTimePeriodID = @SystemTimePeriodID)returnGO
The problem lies in that when a person has a SystemTimePeriodID over a certain value, there is no UserTimePeriod record since it has not been created yet.
Obviously, I need to wrap this in an IF...EXISTS
IF EXISTS (SELECT UserTimePeriodID FROM UserTimePeriod WHERE (SystemTimePeriodID = @SystemTimePeriodID) AND (UserID = @UserID))
(the SELECT above, since that's what needs to come back if the data exists)
ELSE
Do the same select but put in a static value for BudgetCode, like '0000'
GO
How could I do the part where the IF...EXISTS fails?
I'm... not sure I can use RETURNS, since it feeds into this recordset:
rstUserInfo2.Open "UserGetInfo2 " & Request("UserID") & ", " & Request("SYSTIMEPERIODID")
and later uses values from that RecordSet, such as <td><%=rstUserInfo("BudgetCode") & ""%></td>
