ASPNETDB.MDF-uniqueidentifier

Jan 25, 2006

Hi:
I am using the built in securty database from vs2005
I am trying to write an insert trigger that will add a role each time a user is added but I seem to be having difficulty I believe it's with the uniqueidentifier datatype. when I run this trigger via an insert statement I get the following error.
Can anyone set me straight?
========error==============
Cannot insert the value NULL into column 'RoleId', table 'R:AAAPROJECTSASPVS2005MERCERBUCKSAPP_DATAASPNETDB.MDF.dbo.aspnet_UsersInRoles'; column does not allow nulls. INSERT fails.
==================insert statement==========

Declare @NewUserID as uniqueIdentifier
set @NewUserID=newID()
print Cast(@NewUserID as varchar(50))
insert into dbo.aspnet_Users (ApplicationID,UserID,UserName,LoweredUserName,LastActivityDate)
Values('f23f01f0-7ad7-463b-87e2-f3e9141e6426',@NewUserID,'lrchase','lrchase','7/20/2005')
======trigger============================
set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
go


ALTER TRIGGER [InsertRole]
ON [dbo].[aspnet_Users]
AFTER INSERT
AS
DECLARE @RoleID uniqueidentifier
DECLARE @UserID uniqueidentifier
Select @UserID=Userid from inserted
Print @UserID
SELECT @RoleID = RoleID
FROM dbo.aspnet_Roles where dbo.aspnet_Roles.LoweredRoleName='user'
Print @RoleID
SET NOCOUNT ON;
Insert Into dbo.aspnet_UsersInRoles
Values(@UserID,@RoleID)

Moved Aspnetdb To SQL Server - What Permissions Do I Need To Give The ASP IIS Service Account For That? (Getting: Cannot Open Database Aspnetdb Requested By The Login. The Login Failed.)

May 12, 2008

I am getting the error:
Cannot open database "aspnetdb" requested by the login. The login failed.
When I browse to my ASP.NET 3.5 LINQ web application on the IIS 6.0 server on Server 2003.
I imagine this is because while I granted SQL Server 2005 login and permissions to my database that the application stores its data in, I did NOT grant any rights to the service account the IIS Application Pool uses for its identity to the aspnetdb database on SQL Server which is where all my roles information is stored at.
My question is what are the MINIMUM permissions needed for this database so it can perform its roles related functions?
I'm using Windows Authentications with the SQL Role provider for authorization.
 
Thank you.
 
 
EDIT: I think I only need to open the aspnetdb database and add my login to the aspnet_Roles_FullAccess role.  Is that correct?

Uniqueidentifier

Jul 17, 2003

Hi,

I am using UNIQUEIDENTIFIER column for my table. I do not insert data for it. I left it on database by setting to default NEWID(). Now in my application I need the value of UNIQUEIDENTIFIER column I just inserted. Is there any function or query to get this value like in case of IDENTITY column we can get the latest inserted value from select @@IDENTITY.

Thanks and regards,
Uday

Hey I was curious about the Uniqueidentifier is that better then using the @IDENTITY, apparently the Unique uses your computers mac address as a base???

does SQLCE supports the use of uniqueidentifier datatype.and how can i use it?
i have heard that SQLCE supports only integer type as identity column.
so what datatype i should use for identification(primary key).

Uniqueidentifier Inner Join Int

Nov 5, 2007

I have a table with id(uniqueidentifier) as the primary key, and another table with id(int) as the foreign key.
When I try to INNER JOIN them on id=id  in a view, I get an error that uniqueidentifier and int are incompatible.
I'm new to SQL SERVER and I consider uniqueidentifier as equal to AutoNumber in MSAccess. Isn't it so? If not, how do I make this JOIN work?

Return A UNIQUEIDENTIFIER

Feb 9, 2005

Hi,

I am writing a C# application that uses a SQL server database to hold its data. I need to create a stored procedure that returns a particular row's primary key value. This is no problem if the primary key is an INT. But my primary key is a unique identifier, and the stored procedure doesn't want to let me return any values that aren't INTs. Can someone please tell me how to get around this?

Thanks in advance.

Foreign Key Is An Uniqueidentifier

Nov 10, 2005

Hello everyone.
I have 2 tables in MSSQL Server 2000, Products(idProduct, idProductType, name, quatity) and ProductsType(idProductType, name).

idXXXX are the primery keys and the data type is uniqueidentifier.

In table Products, the collum idProductType is a foreign key refering table ProductsType.

I can insert as many product types as i want without any problems.
Insert INTO ProductsType(name) VALUES('milk')

When inserting products i use the idProductType that was automatacly generated in last insert.
INSERT INTO Products (uuidProductType,name,quantity,)
VALUES ('AD9388A3-CA86-482D-B57F-6FA068E7D405','President Milk 50cl',500)

but i got the following error in SQL Query Analyzer:
Server: Msg 8169, Level 16, State 2, Line 1
Syntax error converting from a character string to uniqueidentifier.

I have searched the forum and i cant find any solution. i need to use uniqueidentifer data types because replication with PDA devices.

Any tips?

Thank you in advance.

Problem With Sp And Uniqueidentifier

Hi,

I use this procedure to add a record to the db (SQL 2005)
i constantly get this error:

Conversion failed when converting from a character string to uniqueidentifier.

This is the sp:

set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
go

ALTER PROC [dbo].[AddBootloader]

@BootName nvarchar(50),
@Version nvarchar(50),
@CSD nvarchar(50),

VALUES

(
@BootName,
@Version,
@CSD,
@CreatorID,
@FilePath,
@FileSize)





And this is the table:

USE [Ebdata]
GO
/****** Object: Table [dbo].[EB_Bootloaders] Script Date: 07/12/2006 10:06:42 ******/

GO
ALTER TABLE [dbo].[EB_Bootloaders] WITH NOCHECK ADD CONSTRAINT [FK_EB_Bootloaders_aspnet_Users1] FOREIGN KEY([UpdateUser])
REFERENCES [dbo].[aspnet_Users] ([UserId])
NOT FOR REPLICATION

The funny thing is that i copied the sp code from another which runs perfect,
I insert a Guid from an asp.net page.

Hope someone can help me here because im am stucked!

UniqueIdentifier As Primary Key.

Jan 17, 2008

SQL2K SP4

Greetings. I just inherited doscovered a 3gb DB that is chewing up lots of CPU time on a pretty beefy server. This DB uses 4 main tables. It has many more, but most of the Inserts/ Updates/ Deletes/ and Joins are done mainly on 4 tables. Anyways, I figured out which sprocs use the most CPU between the hours of 7 and 7 every day, off to a good start. The first one is hardly every run. While it is a pig in terms of CPU usage, the amount of times it's run is somewhat minimal compared to others. So the next one is is a sproc that does auto refreshes, and is run every minute by thousands. I start to analyze it, particularly for missing indexes, but all is well. So I'm beating my head up against the wall and I realize, THE CLUSTERED PRIMARY KEY (PK) FOR THESE TABLES USE A GUID DATA TYPE....

So I have some questions about this data type, and also inserting into a clustered PK in general.



Are joins on this data type as bad as joining on varchar columns in terms of speed?

I don't see that any of my insert sprocs are taking a long time. So if an insert occurs, and a page split needs to happen (which is quite potential with this data type as a clustered PK), does it -- A) Begin the insert, complete the insert, then do a page split? Or does it -- B) Begin the insert, do the page split, then complete the insert?
If A, it would make sense that I would see no lag for my insert sprocs, but also see a high CPU usage (provided I have a high number of page splits, which is yet to be determined. If B, I would expect to see a lot of long running insert sprocs, which I don't.

I have a table that contains a uniqueidentifier column and then another table that contains a foreign-key column, but is set up as varchar. I am building a stored procedure, however I get the following error: "Syntax error converting from a character string to uniqueidentifier"

I tried casting the UID column to a varchar, but this does not work either.

This is a simple select where the column in the foreign table is equal to the ID column of the main table.

Is there a way to solve this without having to make any table changes?

Thanks for the help.

Uniqueidentifier Vs Identity Performance

Aug 30, 2006

Hello,I am using the login controls in 2.0. Each new member has a UserId created : it's a Guid, so a uniqueidentifier in sql server.I also have many tables and stored procedures of my own, and the member id is in most of them.Here is my question: should I keep the uniqueidentifier UserId for all my tables and sp, or should I create a new memberId as an IDENTITY(int) (and for sure link it with the log in userid) in order to get a better performance. I have read many things saying that uniqueidentifiers would reduce the performance, but also others who say it won't be significant. Who's right in this uniqueidentifier vs integer competition ??? Thanks for your recommandations.

UniqueIdentifier In Stored Procedure

Sep 8, 2006

I am trying to convert an SQL statement to a strored procedure and am having a bit of a problem with a GUID variable.The variable is sent from the button command CommandName='<%# Bind("APN_Product_Detail_id") %>'This in turn gets sent to the paramater of the SQL text by : MyLookupCommand.CommandText = "SELECT APN_Product_Detail_id FROM TableA WHERE (APN_Product_Detail_id = @APID1)"  MyLookupCommand.Parameters.AddWithValue("@APID1", e.CommandName)MyLookupCommand.CommandType = CommandType.Text And this works sending the text type to @APID1HOWEVERif I try and convert this to a stored proceduremyparameter1 = MyLookupCommand.CreateParameter()myparameter1.ParameterName = "@APID1"myparameter1.Direction = ParameterDirection.Inputmyparameter1.SqlDbType = SqlDbType.UniqueIdentifiermyparameter1.Value = e.CommandName It does not allow the text (e.commandName) to be converted to a UniqueIdentifer. This must be a Unique Identifier as when executing the stored procedure it insists that  @APID1 is UniqueIdentifier ALTER PROCEDURE dbo.SP_ChooseProductSelected  (@APID1 UniqueIdentifier) AS SELECT Affilaite_Product_new.APN_Include_ID AS APNINCLUDEID, Include.Include_Action, Include.Include_ID, Affilaite_Product_new.APN_Product_Detail_id FROM Affilaite_Product_new INNER JOIN Include ON Affilaite_Product_new.APN_Include_ID = Include.Include_ID WHERE (Affilaite_Product_new.APN_Product_Detail_id = @APID1)   RETURNI Hope that this makes sence. Basicall how do I get the e.CommandName value to a UniqueIdentifier in the stored procedure.Any ideas most welcome

Joins On Uniqueidentifier Columns

Nov 23, 2006

I have recently introduced Microsoft’s
user/roles facility by running aspnet_regsql.exe against my database so that I
would be able to link activities with staff members.



In testing I was able to

Join 2
tables (Reservations and aspnet_Users) with the join fields being of type
uniqueidentifier, using SQL Server Manager Studio Express diagram
facility; Create
a record in aspnet_Users using Microsoft’s
Website Admin toolCreate
a record in Reservations and paste in the contents of uniqueidentifier
field in aspnet_Users using SQL Server Manager Studio Express



All the basic tests had been fine so I created a web page
with a detailsview of the Reservations table and made a templated field (in the
insertitemtemplate), replaced the text box with a dropdown and did a bind of
that dropdown to the relevant records in the aspnet_Users table i.e. UserName
and UserId columns with UserName being displayed. The source is as follows:

    <asp:TemplateField HeaderText="Taken By" SortExpression="RES_Taken_By_Staff_ID">

                    <EditItemTemplate>

                        <asp:TextBox ID="TextBox5" runat="server" Text='<%#
Bind("RES_Taken_By_Staff_ID") %>'></asp:TextBox>

                    </EditItemTemplate>

                    <InsertItemTemplate>

                        <asp:DropDownList ID="DropDownList5" runat="server" DataSourceID="SDSStaff" DataTextField="UserName"

                            DataValueField="UserId">

                        </asp:DropDownList><br />

                        <asp:SqlDataSource ID="SDSStaff" runat="server" ConnectionString="<%$ ConnectionStrings:ReservationsDBConnectionString %>"

                            SelectCommand="SELECT
[UserId], [UserName] FROM [vw_aspnet_Users]"></asp:SqlDataSource>

                    </InsertItemTemplate>

                    <ItemTemplate>

                        <asp:Label ID="Label5" runat="server" Text='<%#
Bind("RES_Taken_By_Staff_ID") %>'></asp:Label>

                    </ItemTemplate>

                </asp:TemplateField>

           

 

Everything looks OK, the correct data appears in the dropdown
but when I hit the INSERT button I receive the following failure message:

 

Implicit conversion from data type sql_variant to uniqueidentifier is
not allowed. Use the CONVERT function to run this query.

Description: An unhandled exception
occurred during the execution of the current web request. Please review the
stack trace for more information about the error and where it originated in the
code.

Exception Details: System.Data.SqlClient.SqlException: Implicit
conversion from data type sql_variant to uniqueidentifier is not allowed. Use
the CONVERT function to run this query.

 

 

I can’t quite see what I should do so I would be
grateful for any help.

Handling / Converting SQL 'uniqueidentifier'

Mar 18, 2007

my environment: WXP pro, VisualStudio 2005, SQL express Adv. with SP1
When running below code I get following error on statement Nr:14.
Error:"Implicit conversion from data type sql_variant to uniqueidentifier is not allowed. Use the CONVERT function to run this query."
What would I like to achieve:In 'mr.memberid' (9) I correctly get the PrimaryKey as 'uniqueidentifier'. In another .aspx.vb file I later use 'Session("MemberGuid")' to fill correctly a GridView based on this value!
Now, on statements (11 - 14) I would like to insert a record where field 'Member' ('Type' is also 'uniqueidentifier') should be filled using this 'uniquidentifier, but as said, I get above msg.
When using (11, no String in 'mr.member' !):'SqlDSEnrolled.InsertParameters("Member").DefaultValue = mr.memberid' I get error msg: "Value of type 'System.Guid' cannot be converted to 'String'."
Can anybody help me on how to achieve this Conversion correctly and where to do the conversion? Thanks for your timeed1 Protected Sub EnrollButton_Click(ByVal sender As Object, ByVal e As System.EventArgs)
