Dear Folks,
can you please tell me, how many newid's can be generated by an sql server instance? and the newid generated by one instance can possibly be generated by another instance ? please give me brief regarding this
thank you very much

Is there a limitation of using:set @sessionID = NEWID()would there be a simular NEWID() being generated if used in a databaseapplication.Eugene Anthony*** Sent via Developersdex http://www.developersdex.com ***
View 1 Replies View RelatedHello,
I use VB.Net and SQL CE 2.0. I'd like to start using UniqueIdentifier fields as my primary keys.
I saw that this would return a NewID value
System.Guid.NewGuid().ToString()
however, it is not supported in Compact Framework. So how can one obtain the next NewId()?
Thank you.
when you use newid() is that a new uniqueidentifier for the database or for the table???I have a changelog that captures newly created users first and gives them a newid, then i want to approve that change and copy the newid generated for that user into the user table. Will I run into duplicate id's that way???
View 1 Replies View RelatedExcuse my ignorance because I don't do advance db related programming,but have no other choice at the moment. My experience is limited tosimple queries.I need to have the following query display the recordset in random orderbased on RecordID (unique key) if possible. I tried the ORDER BY NewID()at the end and it generated an error (ORDER BY items must appear in theselect list if SELECT DISTINCT is specified.) I guess because of the subquery. I would also like for the recordset to display a different 10records on each hit to the page, not just the same 10 records in randomorder.

Why am I getting a different numbers of distinct ids in those queries?
USE AdventureWorks

hi guys
cant find the prob, please help
ALTER TABLE [dbo].[tblUserDetails]

I've been trying to figure out why these two return a different amount of distinct ids...
Is that a bug in optimization?

I have a view which at the moment has no unique identifier on each record. When I try adding a column definition to the view such as NEWID() as TransactionId, the view then cannot 1) be selected into a temporary table, or 2) queried on other columns in the table. In either case I end up with an empty result set.
I believe I have a way around this for my purpose, which was principally testability. However, can anyone enlighten me as to how and why this happens?

I have an application being developed using SQL server.
The data is captured at various remote areas and the
SQL servers are not physically connected to each other.
Periodically either through a replication / backup process
i plan to update the data from various servers into a central
database.
Can i use the NewID() function to generate a unique ID which
i can use as a primary key that would not be duplicated
across all these servers?
if not Please suggest a solution to maintain the uniqueness
of the transaction.
thanks in advance
I have 2 tables, Artists and Artworks.
I have a query:
SELECT TOP (4) dbo.Artists.ArtistID, dbo.Artists.FirstName + ' ' + dbo.Artists.LastName AS FullName, dbo.Artworks.ArtworkName, dbo.Artworks.Image
FROM dbo.Artists INNER JOIN
dbo.Artworks ON dbo.Artists.ArtistID = dbo.Artworks.ArtistID
ORDER BY NEWID()
This query returns random images, but the artists are sometimes repeated.
I would like to have DISTINCT Random Artists returned, each with a random image. I tried various subqueries, but I just get error messages.
Any help would be appreciated.
Thnks,
Paolo
Is it possible to use NEWID() as a parameter to a stored procedure inSQL Server 2000. I keep getting a "Line 1: Incorrect syntax near ')'"error.ALTER PROCEDURE dbo.StoredProcedure1(@x uniqueidentifier)AS/* SET NOCOUNT ON */RETURNStoredProcedure1 NEWID()go"Line 1: Incorrect syntax near ')'"Thanks in advance
View 1 Replies View RelatedHello.So the scenario is a little complicated.I am joining two tables.Table 1 is derived; it has one row; it has a column based from newid()Table 2 joins to table 1 and reuses the newid() value from table 1 in table 2's rowsBecause there is only one row in Table 1, the value of newid() REPEATS in Table 2The bug is that the NewId() value from Table1 is REGENERATED with every Table 2 record.I created a blog about this because it takes a code sample to demonstrate:http://jerrytech.blogspot.com/2008/04/sql-2005-tsql-bug-with-newid-in-derived.html

Hi There,
I'm having a problem retreiving the auto generated Guid after inserting anew record with NEWID(), my stored proc is as follows:SET @uiTransactionID = NEWID()
INSERT INTO Transactions (uiTransactionID) VALUES (@uiTransactionID)
IF @@ERROR = 0 AND @@ROWCOUNT = 1
BEGIN
SELECT @uiTransactionID AS '@@GUID'
RETURN 0
END
And the return on my insert statement is:
command.ExecuteNonQuery();m_uiTransactionID = (Guid)command.Parameters["RETURN_VALUE"].Value;
I can never retreive the newly generated Guid, can onyone spot where i'm going wrong?
Many thanks
Ben
Hi,What I am trying to do is to get the new ID for every record is inserted into a table. I have a For...Each statement that does the loop and using the sqldatasource to so the insert. <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ myConnectionString%>">
<InsertParameters>
<asp:Parameter Name="NewID" Type="int16" Direction="output" />
</InsertParameters>
</asp:SqlDataSource> Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim sqlSelect As String
Session("Waste_Profile_Num") = 2
Session("Waste_Profile_Num2") = 5
sqlSelect = "SELECT Range, Concentration, Component_ID FROM Component_Profile WHERE (Waste_Profile_Num = " & Session("Waste_Profile_Num").ToString() & ")"
SqlDataSource1.SelectCommand = sqlSelect
Dim dv As Data.DataView = CType(SqlDataSource1.Select(DataSourceSelectArguments.Empty), Data.DataView)
For Each dr As Data.DataRow In dv.Table.Rows
sqlSelect = "INSERT INTO Component_Profile (Waste_Profile_Num, Range, Concentration, Component_ID) "
sqlSelect &= "VALUES (" & Session("Waste_Profile_Num2").ToString() & ", @Range, @Concentration, @Component_ID); SELECT @NewID = @@Identity"
SqlDataSource1.InsertCommand = sqlSelect
'SqlDataSource1.InsertParameters.Add("Waste_Profile_Num", Session("Waste_Profile_Num2").ToString())
SqlDataSource1.InsertParameters.Add("Range", dr("Range").ToString())
SqlDataSource1.InsertParameters.Add("Concentration", dr("Concentration").ToString())
SqlDataSource1.InsertParameters.Add("Component_ID", dr("Component_ID").ToString())
SqlDataSource1.Insert()
SqlDataSource1.InsertParameters.Clear()
MsgBox(Session("NewID").ToString())
Next
End Sub
Protected Sub SqlDataSource1_Inserted(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceStatusEventArgs) Handles SqlDataSource1.Inserted
Session("NewID") = e.Command.Parameters("@NewID").Value.ToString
End Sub What I have done so far is to display the new id and I am going to use that return id later. However, the first time through the loop, I am able to get the new id but not the second time. So, I wonder, how do I every single new id each time the INSERT statement is executed?STAN
I'm migrating a web based system to SQL server. I'm planning on using the SQL server function NewID() to create unique keys for many of my records in many different tables. I'm just wondering if NewID() is guaranteed to return a value that does not already exist in my database. I mean obviously once you have a certain number of records (a hell of a lot) you'd be breaking the odds to never come up with a duplicate. Do I need to make sure the result of NEWID() doesn't already exist?Thanks
View 1 Replies View RelatedI currently have a table called stores. I've just added a uniqueidentifier column called store_guid to the stores table. The table currently has about 500 records in it and now i'm trying to set each store_guid = to a newid(). I've tried using UPDATE stores SET store_guid = newid() . however, that doesn't work because i think it's trying to set each record equal to the same guid using that approach. All i need to do is fill in my new column with new guids. any ideas?

I'm trying to use the NEWID function in dynamic SQL and get an errormessage Incorrect syntax near the keyword 'ORDER'.
