Guid Vs Identity
Jul 20, 2005Hi,
Is there any replace for "Select @@identity" that could return "just
inserted" GUID as a primary key?
Has anyone tested what's faster, working with Guid or Autonumber ?

Major Problem With @@IDENTITY, Treeview And GUID
Nov 14, 2004Hi,
I'm trying to insert data into locally stored database (SQL Server).
The data I want inserted, is presented in a Treeview control and the data is fetched from a Webservice. The data is returned in form of a dataset.
The treeview contains checkboxes allowing a user to select what to install in the locally stored database.
To sum up:
1. Get data from a webservice' not my problem
2. Present data in a Treview control' not my problem
3. Allow to user to select which data to install' not my problem
4. Insert data that the user has selected into my db' MY PROBLEM!!!!
The Treeview looks like this.
- Group1
| | ---- Rule1.1
| | ---- Rule1.2
|
- Group2
| | ---- Rule2.1
| | ---- Rule2.2
| | ---- Rule2.3
.....
The Treeview is generated with DataRelations between Group and Rule.
My locally stored database is designed by a third party provider and therefore the database must not be altered.
The table I want to store data in is called "Groups" and it looks like this:
GroupID uniqueidentifier ' (newid())
GroupName nvarchar(50)
ParentGroupID uniqueidentifier' if grouptype = 0 then ParentGroupID must have a value.
GroupType tinyint ' 0 = subgroup, 1 = "top"group
Data in the table "Groups" would look like this:
GroupID GroupNameParentGroupIDGroupType
---------------------------------------------------------
{000001...}Group1<NULL>1
{000011...}Rule1.1{000001...}0
{000012...}Rule1.2{000001...}0
{000002...}Group2<NULL>1
{000021...}Rule2.1{000002...}0
{000022...}Rule2.2{000002...}0
{000023...}Rule2.3{000002...}0
The third party also created a stored procedure called pr_AddGroup taking the following parameters:
@GroupName ' can be both the RuleName and the GroupName
@GroupType ' can be 0 for subgroup or 1 for "top"group
@ParentGroup ' GUID
The problem with this stored procedure is that it does not have return value, which is here my problem actually lies.
If it returned @@IDENTITY I could use this as the parameter for @ParentGroup.
Instead I figure I must create two sqlCommand's (one calling pr_AddGroup and another calling SELECT @@IDENTITY to get the newly created record).
My SQL Commands look like this
Dim cmd As SqlCommand
Dim Conn As SqlConnection = New SqlConnection
Conn.ConnectionString = "Data Source=myServer;Initial Catalog=myTable;Integrated Security=SSPI"
cmd = New SqlCommand
cmd.CommandType = CommandType.StoredProcedure
cmd.Connection = Conn
cmd.CommandText = "pr_AddGroup"
cmd.Parameters.Add(New SqlParameter("@GroupName", SqlDbType.NVarChar, 50, ParameterDirection.Input))
cmd.Parameters.Add(New SqlParameter("@GroupType", SqlDbType.TinyInt, ParameterDirection.Input))
cmd.Parameters.Add(New SqlParameter("@ParentGroup", SqlDbType.UniqueIdentifier, ParameterDirection.Input))
dim cmd2 as SqlCommand
cmd2 = new SqlCommand
cmd2.commandtype = commandtype.Text
cmd2.commandtext = "SELECT @@IDENTITY as ID FROM Groups"
cmd2.connection = Conn
dim ParentGroupGUID as system.guid
To get the data inserted in the Groups table I would something like the following, but the code is very ugly
(and it doesn't work either);
For Each Group In TreeView1.Nodes ' Loop through Groups
If Group.Checked Then
cmd.Parameters("@GroupName").Value = Group.Text.ToString
cmd.Parameters("@GroupType").Value = 1
cmd.ExecuteNonQuery()
ParentGroupGUID = cmd2.executescalar()
End If
For Each Rule In Group.Nodes ' Loop through Rules.
If Rule.Checked Then
cmd.Parameters("@GroupName").Value = Group.Text.ToString
cmd.Parameters("@GroupType").Value = 1
cmd.Parameters("@ParentGroup").value = ParentGroupGUID
cmd.ExecuteNonquery()
End If
Next
Next
I've spent the last 5 hours figuring out this problem, so ANY help is appreciated :-)
How To Retrieve The GUID Value Of A SQL NewID() Identity Column After An Insert ?

Last GASP On Insert Row In Table With Identity Field, And Get New Identity Back ?
Jul 9, 2006While I have learned a lot from this thread I am still basically confused about the issues involved.
.I wanted to INSERT a record in a parent table, get the Identity back and use it in a child table. Seems simple.
To my knowledge, mine would be the only process running that would update these tables. I was told that there is no guarantee, because the OLEDB provider could write the second destination row before the first, that the proper parent-child relationship would be generated as expected. It was recommended that I create my own variable in memory to hold the Identity value and use that in my SSIS package.
1. A simple example SSIS .dts example illustrating the approach of using a variable for identity would be helpful.
2. Suppose I actually had two processes updating these tables, running at the same time. Then it seems the "variable" method will also have its problems. Is there a final solution other than locking the tables involved prior to updating them or doing something crazy like using a GUID for the primary key!
3. We have done the type of parent-child inserts I originally described from t-sql for years without any apparent problems. (Maybe we were just lucky.) Is the entire issue simply a t-sql one or does SSIS add a layer of complexity beyond t-sql that needs to be addressed?
TIA,

Insert Row In Table With Identity Field, And Get New Identity Back
Jun 30, 2006I want to insert a new record into a table with an Identity field and return the new Identify field value back to the data stream (for later insertion as a foreign key in another table).
What is the most direct way to do this in SSIS?
TIA,

P.S. Or should I pass the identity value back in a variable and not make it part of the data stream?
GUID's
Feb 1, 2001we are currently using id's as primary key and replication is not part of our project.

GUID
May 26, 2006Hello,
I'm working on a smart client app that has an offline sql express store and needs to work with several types of central databases (support for multiple products - ms sql, DB2 etc)
While trying to put together some offline functionality that needs the user to create records on the offline sql express data store, we've run into the need of being able to uniquely identify records so replicating the data in the offline store back into the primary database should not be a problem.
The data created offline spans many tables and involves several tables with relation ships - FK etc...Clearly not a simple case of store and forward.
We dont want to get into the mess of performing key replacement during a synch job with the server. Thats way too much trouble.
GUID seems like a good choice, but as always we have several stake holders having different opinions. And with databases other than MS SQL we will have to store them as strings.
To cut to the chase - can we not hash a GUID to get an integer while retaining atleast the same likelyhood of producing unique ids ? [no drop]
Thanks,
Aviansh
Profile GUID
Apr 13, 2007I am using a SqlDatasource and need to set a SelectParamter to the ProviderUserKey (The GUID of the user when Profiles are enabled)
Can anyone tell me whether it is possible and How?
I am currently using the session state to store it in and then using the session=... to get the value into the parameter.
Is there a direct way of passing this value into a SelectParameter when using a SqlDataSource?

How To Specify A Guid In A WHERE Clause
Sep 25, 2007Hi Everyone,
I'm trying to create a SQL Delete statement using a string builder and the WHERE clause uses a Guid. Here is the code:stb.Append("DELETE FROM UserRights WHERE UserIDPtr = ");
stb.Append(TargetUserID);The resulting string is: "DELETE FROM UserRights WHERE UserIDPtr = e01549fb-edf5-4668-de8b-b13dd5661a6e"
When I try to do an ExecuteNonQuery() using the string as the CommandText, I get an error.
Invalid column name 'e01549fb',Invalid column name 'edf5',Invalid column name 'de8b',Invalid column name 'b13dd5661a6e'
It is also strange that '4668' did not show up as an invalid column name, but I don't think that is relavent to this issue.
Can someone show me (or point me to an article) about using Guid's in a text string as a SQL command? Thanks in advance!
GUID Issues
May 5, 2008My database is using the membership store for all the user information. I added a tabel "Skills" with 3 fields "SkillID (GUID)" "SeekerID (GUID, This is the UserId)" and "SkillName ( Varchar(MAX))"
on the page i have a ListView setup to display the SkillName fields based on the SeekerID.
The original code was Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
' Get a reference to the currently logged on user Dim CurrentUser As MembershipUser = Membership.GetUser
' Determine the currently logged on user's UserId value
Dim SeekerID As Guid = CType(CurrentUser.ProviderUserKey, Object)
End Subthat kept returning string to GUID conversion errors, so i had to change Dim SeekerID As Guid = CType(CurrentUser.ProviderUserKey, Object) to Dim SeekerID As Object = CType(CurrentUser.ProviderUserKey.ToString(), Object) that appears to be working now. On the same page however, I want to insert records into the table, I tried 2 options both of which have a different problem.
Option 1: Use a textbox (ID = NewSkill) and a button with the following code on it:
Protected Sub SetNewSkill_Click(ByVal sender As Object, ByVal e As System.EventArgs) Dim CurrentUser As MembershipUser = Membership.GetUser
Dim SeekerGUID As Object = CType(CurrentUser.ProviderUserKey, Object)
Dim NewSkill As TextBox = CType(FindControl("NewSkill"), TextBox) Dim connectionString As String = ConfigurationManager.ConnectionStrings("QJSdatabase").ConnectionString()
Dim insertSql As String = "INSERT INTO Skills(SeekerID, SkillName)VALUES(@SeekerGUID, @NewSkill)" Using myConnection As New SqlConnection(connectionString)
myConnection.Open() Dim myCommand As New SqlCommand(insertSql, myConnection)
myCommand.Parameters.AddWithValue("@SeekerGUID", SeekerGUID) myCommand.Parameters.AddWithValue("@NewSkill", NewSkill.Text.Trim())
myCommand.ExecuteNonQuery()
myConnection.Close()
End Using
End Sub
Problem: myCommand.Parameters.AddWithValue("@NewSkill", NewSkill.Text.Trim()) gets outlined and returns the error: Object reference not set to an instance of an object
Option 2: Use a DetailsView linked to a SQLDataSource on the page
<asp:DetailsView ID="DetailsView1" runat="server" Height="50px" Width="210px"
AutoGenerateRows="False" DataSourceID="SqlDataSource2" DefaultMode="Insert"> <Fields>
<asp:BoundField DataField="SkillName" HeaderText="Add Skill:" SortExpression="SkillName" />
<asp:CommandField ShowInsertButton="True" />
<asp:TemplateField InsertVisible="False">
<EditItemTemplate>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="Label1" runat="server"></asp:Label>
</ItemTemplate>
</asp:TemplateField>
</Fields>
</asp:DetailsView>
<asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:database %>"
DeleteCommand="DELETE FROM [Skills] WHERE [SkillID] = @SkillID" InsertCommand="INSERT INTO [Skills] ([SeekerID], [SkillName]) VALUES (@SeekerGUID, @SkillName)"
SelectCommand="SELECT SkillName FROM [Skills]"
UpdateCommand="UPDATE [Skills] SET [SkillName] = @SkillName WHERE [SkillID] = @SkillID">
<DeleteParameters>
<asp:Parameter Name="SkillID" Type="Object" />
</DeleteParameters>
<InsertParameters>
<asp:Parameter Name="SeekerGUID" Type="Object" />
<asp:Parameter Name="SkillName" Type="String" />
</InsertParameters>
<UpdateParameters>
<asp:Parameter Name="SkillName" Type="String" />
<asp:Parameter Name="SkillID" Type="Object" />
</UpdateParameters>
</asp:SqlDataSource>
http://junk.icore-studios.com/junk/Codeissues/postresumeerror.html
The @SeekerGUID is being generated by the same pageload code as the first chunk i gave (I have 2 variables SeekerID is the GUID converted to string to work with the ListView filter and SeekerGUID is the GUID)
Ultimatly getting either option to work would be fine. Though I think the second would be preferable because I think it'd be easier to replicate later on.
Thanks in advance for your time and any help
GUID Troubles.
Apr 17, 2004Hi,
I am having a hard time updating a database row using a UNIQUEIDENTIFIER. I retrieve the row into a datagrid and then use the GUID as a parameter to a stored procedure, but it doesn't update. If I run the query in SQL Analyser ... it works. Any ideas ? Here's my stored proc ... I tried passing a varchar and doing the conversion in the SP ... no go !! I am using MApplicationBlockD.
CREATE PROCEDURE spScanUpdate
@id varchar (100),
@name varchar (75)
AS
DECLARE @GUID_ID as uniqueidentifier
SELECT@GUID_ID = CAST ( @id as uniqueidentifier )
UPDATE tScan
SET name = @name
WHEREid = @GUID_ID
GO

View 5 Replies View RelatedGUID Performance
Apr 11, 2008I have a database with tables with GUID's als primary keys.
Because of the uniqueness GUID's are a performance hit on INSERT records.
So I wanted to use NEWSQUENTIALID() to make INSERTS faster.
Does NEWSQUENTIALID() increase performance as well with SELECT statements? Or is the benefit between NEWID() and NEWSQUENTIALID() only when INSERTing records?

Loving GUID's
Apr 29, 2008I'm reluctant to admit I'm in love with uniqueidentifiers AKA guid's.
However, this love comes with a cost because of the size and thus SQL Cache and thus IO reads (and fragmented index pages and so on)
My love has to do with generic programming and keeping multiple database updateable (adding core functionality with the flexibility to let users add and change data in tables that have core data in it as well). Also merging databases is easy or relate different entities by storing a metadata link table.
So, what I'm trying to do is making the disadvantages as small as possible.
So I'm using NEWSEQUENTIAL Id's and retrieve new made records with OUTPUT as TABLE.
So I changed the default CLUSTERED INDEX as NON-CLUSTERED.
I'm not fond on usings numerics for some primary keys and uniqueidentifiers for others.
What else can I do to keep using GUID's as primary keys with as less disadvantages as possible?

GUID As Primary Key
Mar 13, 2008I have a table profiles and a table resumes.
The id's are currently int indentity fields.
I was thinking of using a GUID as ID.
Why would i do this ?
In my webapplication I have i.e. this page
DeleteProfile.aspx?profileId=1
I don't want to give the user the ability to change this to f.e.
DeleteProfile.aspx?profileId=3
A user will almost possibly never guess a certain GUID, right ?
Is this a good idea, or not ?
Is A GUID Always Unique?
Jul 20, 2005Greetings All, I have read many upon many articles here regarding GUIDdata types and uniqueness. There have been many opinions regardingthe effectiveness of GUID's and when they should/should not be used.However, every article strongly implies, if it does not state itoutright, that GUID's are always unique. My question is this, whathappens if you have a database that uses GUID's and the NIC is changedout on the box? From what I understand the MAC address of the NIC isused as part of the algorithm to generate a GUID. If you change outthe NIC after generating 1 billion GUID's do you run the chance ofgenerating a duplicate GUID?I look forward to your insightfulness on this issue.Regards, Louis.

GUID Question
Sep 17, 2006I am reading a book and it talks a little bit about using GUIDs as primary keys. I am very confused about this because if this is a generated value per table, how could you use it as a foreign key in another table as it appears to be uniquely generated per table. Here is the code in the book which I don't understand. Can someone explain this in simple terms?
I know the identity column would be a problem if I had a multi-terabyte database with huge tables, so what do I do in this situation?
create table dbo.product(
productid uniqueidentifier not null
rowguidcol default (newid())
primary key nonclustered
etc

T-SQL (SS2K8) :: How To Update Identity Column With Identity Value
Jan 25, 2015I have table of three column first column is an ID column. However at creation of the table i have not set this column to auto increment. Then i have copied 50 rows in another table to this table then set the ID column values to zero.
Now I have changed the ID column to auto increment seed=1 increment=1 but the problem is i couldn't figure out how to update this ID column with zero value set to each row with this auto increment values so the ID column would have values from 1-50. Is there a away to do this?

so what im trying to do is create a new record (a workstation) and get back the auto generated ID (its not actually a GUID, its an int which is set to the identity) and then once i have that create other records (for external devices, different table) that will have a link to which machine they are attached to (that Id im looking to get returned)
I know this can be done in a two step process, create the record, query it for its id, and then slap that in my next insert statement for the external devices... but... i know there was a way to do it before and i assume there is a way to do it now...
anyone know how?

Clustered Index On GUID
Dec 5, 2005I have a 3rd party app which creates tables for developers. It uses a guid as the unique key which is indexed. However none of these indexes are clustered. I have hear both good and bad about clustering on a GUID. i can't change this design other than to make these indexes clustered. Any opinions?

GUID's Req'd For Transactional Replication??
Aug 22, 2002Does SQL Server 2000 (Enterprise Edition), mandate the creation of a GUID on each table used in transactional replication?
I was told that in addition to defining a Primary Key, I "MUST" also define a GUID on each table. As I recall - this is not true. Can someone who's setup Transactional Replication please field this question?
thx -

GUID And Curly Braces
Jun 19, 2001If I return a GUID as an output parameter in an ASP page, it has curly braces around it. When I query the table in QA, there are no braces around it. Why is that.
