Rebuildix clutered index on different field

Hello!
I have got a table with clustered key defined on primary key. This tables is
referenced using FK by hundreds of other tables using its primary key. I am
trying to build clustered index on different column in the most efficient
way. It looks like I have to drop PK constraint first before changing
clustered index. This also means I have to drop/recreate all FK constraints
which could be time consuming. I suppose disabling constraints wouldn't
help. Is there quickest way of changing clustered index?
Thanks,
IgorHi
As there can only be one clustered index on a table I think you will need to
drop it which would require all FKs referencing it to be dropped first,
although alternatively you may want to create an indexed view that can have
it's own clustered index.

re-arrange name data

i'm attempting to make a DTS package that will export to a csv each day. my problem is figuring out how to change a name field that stores the data as the following format:

First Middle Last

into

Last, First Middle in the outputted .csv file

thanks in advance.

-csubstring(fld,len(fld) - charindex(' ',reverse(fld)),len(fld))
+ ', ' + left(fld,len(fld)-charindex(' ',reverse(fld)))

The numbers will be a bit wrong but you can fix that.

Real-Time Data Mining Discussion

I am about to prepare a paper concerning the field of real-time data mining. Real-time here means the process of incremental training of an existing model as soon as the data arrives.

There is a number of papers introducing algorithms for incremental association analysis, incremental clustering etc. Stream mining ís a field which is closely related to that. The main reason for the implementation of incremental algorithms is a) the large amount of data to be mined and b) the high rate of new data that is evolving every day.

Using classical batch mining algorithms, models that are outdated for some reason, would have to be re-trained, which could be very time consuming for billions of records. And once the training is completed, the training would have to be restarted once again because a bulk of new data has been arrived.

The question that I would like to discuss now is: For what real world applications would it be a meaningful or even essential to use real-time training of models?

Two main reasons could determine the answer to that question:

You just want to incorporate new data into existing models in order to increase the prediction accuracy of your model or

Your underlying data is subject to more or less massive changes (also refered to as concept drift) and you want to adapt your mining model continuously to that reality.

I'm looking for some examples or ideas where one of these cases apply and it would be a good idea to have incremental mining algorithms involved.

I'm looking forward to inspiring some discussion on that issue.

Whenever you model a control system (like validation edits for an application process), you get the ability to tune the controls to stop unwanted behavior. Users that are subject to the new controls will, over time, begin to understand the controls and start to look for weaknesses in the controls that makes their input tasks easier to accomplish. This may lead to new "unwanted" behaviors and it would be great to have control model that learns on the fly and adjusts when it identifies new unwanted behaviors.|||If you haven't already prepared the paper, here's another potential application. Let's say you are doing data mining on stock price movements. You're passing some sort of stock price history, as well as relating it to day of week, day of month, month, year of presidency, moon cycle, what have you. Statistics generally show, for example, that stock prices move up on Fridays more often than Mondays, and this is thought to be due to short sellers covering their positions so they aren't caught by unexpected events over the weekend.

Let's say you want to update these statistics daily, shortly after market close, to keep your trading strategies up-to-date with current market conditions. You don't want to retrain the model with 100+ years of stock data every day, so it'd be much faster to be able to do incremental updates. This becomes particularly important for options and futures trading (though there's not 100 years of data for that), as for every underlying security there are potentially dozens or even hundreds of contracts trading on the market.

Really urgent - Data field retrieve and store

Basically i make use of FormView in Web Developer Express Edition to create and store information to the database ...

what i want to do further is to capture the value within the primary key of the newly created recordset that I set it become auto increament ....

this value would be stored within a session string in global condition that allowed any page able to access it ....

If you simply want to return the ID to use within the application, and you are using a stored procedure, do this.

Insert the record as normal in the table, then add a statement such as SELECT SCOPE_IDENETITY() as TheNewId

If your insert fails, this line never executes. If insert is OK, you get teh new ID passed back

In your code, perform an execute scaler method call on the connection, and cast the return (decimal as object) into an integer, and store in session. If the returned value is null, the insert failed

What I often create for projects is a global "Execute Scaler" method that accepts the name of a stored procedure, and a string dictionary of name/value pairs.

IN the method, create the SQL Command object, call the SQLCommandBuilder static method to get the parameters, then iterate through the dictionary to add these by name.

Call the command ExecuteScaler as mentioned and proceed as above

|||Really appreciate ur feedback men... but it looks so technical for me men... i am totally a new beginner but have to complete this project within another week time...

can u demonstrate the code (sorry for the hassle)... i kind of not sure how to achieve what u had mentioned...|||

Example SP

CREATE PROCEDURE

dbo.MyTable_Insert

(

@.Parameter1varchar(100)

)

AS

SET NOCOUNT ON

INSERT INTOMyTable (MyData)VALUES(@.Parameter1)

SELECT SCOPE_IDENTITY()asTheNewId

Example Code

int InsertRecord(string insertValue)

{

// assumes you have set cnn as a suitable connection

SqlCommand cmd =newSqlCommand("MyTable_Insert", cnn);

cmd.CommandType = System.Data.CommandType.StoredProcedure;

cmd.Parameters["@.Parameter1"].Value = insertValue;

object retObject = cmd.ExecuteScalar();

if (retObject !=null)

return (int)retObject;

Really need to solve this SQL problem to finish this web site.

Hi,
i created a dataSet in an ASP.Net page which:
1. Loads all fields from each database record.
2. Creates a new field using 2 of the existing fields: FullName = FirstName
+ ' ' + LastName
3. Loads only the record which has the same FullName as the variable Name
passed in the URL to this page.
My SQL is this:
SELECT *, FirstName + ' ' + LastName as FullName
FROM people
WHERE FirstName + ' ' + LastName = ?
and:
<Parameter Name="@.FullName" Value='<%# IIf((Request.QueryString("Name") <>
Nothing), Request.QueryString("Name"), "") %>'
Type="WChar"/></Parameters></MM:DataSet>
Can you please tell me how to do this?
I know i allready asked this but until now i got no solution and i need to
solve this to finish this web site and deliver it.
I hope i was able to explain better my problem.
Thank You Very Much,
Miguel
Why are you putting the Request.Querystring in a pre-render block, should it
not be in regular code with the rest of it ? IE
Value = Request.QueryString("Name")
