Hi,
I have created a database in the SQL Server 2005 and the same database in sql mobile. I have a field, which has a GUID and uniqueidentifier, when i tried to insert the same data which is there in sql server 2005 database into sql mobile database it is giving me error as below
Major Error 0x80040E14, Minor Error 25501
> INSERT INTO TypeValue (TypeValue_ID,DisplayValue,TypeName,OrderIndex,IsActive)
VALUES (b6483fe1-1118-4ba1-9106-0069715a75c0,Asian,ETHNICITY,1,TRUE)
There was an error parsing the query. [ Token line number = 2,Token line offset = 24,Token in error = ba1 ]
Please suggest me any solution.
Thank you,

Dear ppl,
I am writing an application for a device (MDA Pro T-Mobile) having Windows Mobile 5.0 using
-MS .NET Compact Framework 2.0 SP-1
-SQL Mobile 2005.
-VS 2005 .NET
The application uses Merge Replication. The error occurs in the Synchronise() Method of the SqlCeReplication object.
"SQL Server Mobile encountered problems when opening the database."
repl.AddSubscription(AddOption.CreateDatabase);
repl.Synchronize();
I don't understand why I am having this error. It does create the database on AddSubscription() method but it is failing opening the database on Synchronise(). I have also tried uninstalling and then reinstalling all the SQL Mobile components in the following order.
-sqlce30.wce5.armv4i.cab
-sqlce30.repl.wce5.armv4i.cab
-sqlce30.dev.ENU.wce5.armv4i.cab
However, when i run this application on a device(Dell X50 AXIM) with Pocket PC 2003, it runs fine creating the database and sysnchronising it.
The target platform for the project is Windows Mobile 5.0 Pocket PC SDK.
Does any one have any clue what could be the problem ?
Regards
Nabeel
I am migrating a pocket PC application from VS 2003 to VS 2005 and a few weeks ago I hit the following problem when replicating
A SQL Mobile DLL could not be loaded. Reinstall SQL Mobile. [ DLL Name=sqlceca30.dll]
Scanning forums for help I saw that other people had had this problem and one
http://www.eggheadcafe.com/aspnet_answers/NETFrameworkCompactFramework/Feb2006/post25814466.asp
suggested that this problem could be circumvented by getting the replication object early and then continuously using the same object for subsequent replications.
I did this and it works a lot better now but ever so often I get another error which is
Native Error 28559 SQL Mobile encountered problems when opening the database
My only option at this point is to stop and start the application which cures the problem.
Hello,
I am developping a non-managed C++ application for PocketPC using a SQL Server mobile database.
The application is compiled for PocketPC 2003 and uses SQL Server Mobile v2. I use Visual Studio 2005. But I need to compile the application for Windows Mobile 5.0 devices. So I installed the WM5 SDK and had the WM5 into my project configuration.
The "ssceoledb.h" which I include incluses the "transact.h" file. But my problem is that this file is only provided with the PocketPC 2003 SDK and not in the WM5 SDK.
So I cannot use the WM5 configuration project with SQL Server. I also tried with the last SQL Server Mobile 2005 (ie v3.0) and the "ssceoledb30.h" also includes "transact.h".
Did I miss something to install ?
Do you know how I can resolve the problem ?
By advance, thank you for any answer.

Using MS VS 2005 (incl SQL Server Mobile)
MS Pocket PC 2005 SDK
I am working on a project that builds for Pocket PC on both Mobile 2003 and Mobile 5. The project uses/will use SQL Server Mobile to store local data.
Project created from new with support for both platforms. I include required header files ssceerr30.h and ssceoledb30.h.
Project builds fine in WM2003 configuration, release and debug.
When I build for WM5 the compiler cannot find the header file transact.h. This is included from within ssceoledb30.h. Same as under WM2003.
In WM2003 configuration if I highlight the ssceoledb30.h include in Visual Studio and open the header, it takes me to <Visual Studio dir>SmartDevicesSDKSQL ServerMobilev3.0. I then locate the include for transact.h and do the same, which takes me <Visual Studio dir>SDKPocketPC2003include. The file exists.
If I repeat the above 'browsing' under the WM5 configuration, ssceoledb30.h takes me to a different copy in the WM5 SDK directory. There is no diff between the file here and the other copy used by WM2003. If I attempt to open transact.h - file does not exist.
Fix (which I'm not too sure about, i.e. is it OK?) - If I copy transact.h to the WM5 SDK directory, the project builds.
Why has transact.h disappeared from WM5 SDK?
I can find no ref's to this problem anywhere. Is my installation of the WM5 SDK corrupt? What else could I be missing?
Is there a sample for SQL Server mobile (like the NorthwindOLEDB sample) that comes configured to build for WM5?
It is possible to access a Sql Server 2005 Mobile database in a VS2003 application (compact framework) ?
Thanks

I receive error 25123 on my PPC (audiovox 6600) in a reproducable way (usually) with .net 2.0 application that is using SQL CE that I wrote:
Open the application
Connect to the database
Close the applicaton
Re-Open the application
Connect to the database <-- Error occurs
I will also receive the error if my application isn't the first application launched (or very close to the first to launch).
I don't believe it's a memory issue as according to the memory manager I have plenty of memory:
At boot up only start screen items loaded: 18.46 Used 49.89 Free
Launch Resco File Explorer to click EXE: 19.18 Used 49.18 Free
Launch my application (no DB connection): 23.64 Used 44.71 Free
Connect to the DB and do select count(*) from a table with 0 rows: 26.27 Used 42.08 Free
Close the application (this.Close() on the form: 19.38 Used 48.97 Free
Relaunch App and connect to DB receive error: around 38 Used around 30 free
I was unable to reproduce the issue right now while typing this message, the last sets of numbers are from memory, and include other applications that are currently running.
The only way I have to get SQL CE to load again is to soft reset the PPC. If the application is able to connect to SQL CE at least once it is fine up till I close it and re-open the application. So it either connects and runs great, or it can't connect at all.
Any help in resolving this issue would be greatly appreciated.

Hi folks, I'm new to Windows Mobile progamming, and new to this forum. Apologies in advance if I'm asking a boneheaded question, but I've done searches and can't find anything directly applicable to my problem.
I'm currently walking through the published MS tutorial in setting up an SQL Server 2005 Mobile application that subscribes to a publication on SQL Server 2005 to exchange information.
I've gotten almost all the way through... successfully set up the server components, creating the publication, etc. On the mobile side, I've been able run the cab files to install the SQL Mobile components and to create the project, add the reference to the dll, and instantiate an engine object. It compiles.
The step in the tutorial after that, though, where you specify the data source from the "data" menu, I've got a problem. When I try to use the "new connection" dialog from choosing the data connection, "MS SQL Server Mobile Edition" doesn't show up as a choice. I've tried choosing any of the other combinations, and in teh subsequent "Connection properties" section my database, SQLMobile (as in their sample) is available, but I get an error when I choose it and click OK. Clicking on "Test Connection" gives me a connection successful message.
My guess is that something about the Mobile server side components is not installed correctly on my development machine, but honestly I have no idea how to begin to fix it. Has anyone seen this problem before and know how to resolve it?
Your time and any knowledge sharing is greatly appreciated.
Thank you,

How do I update the OrderGUID column in Table B with Values from OrderGUID column in Table A. I have already populated the OrderGUID column in Table A using NEWSEQUENTIALID(). Now I need to populate the OrderGUID column in Table B with Matching GUID values from the OrderGUID Column in Table A.
Does any one have a script to accomplish this task. thanks
This is a great tutorial and it's a shame one of the more important steps was missed.
In the €œCreate the snapshot user€? section you you find the steps to create the snapshot_agent account. Then in the €œCreate the snapshot folder€? section you find the share and folder permissions. However, at no point do the instructions advise you about adding the snapshot_agent to the SQL Server Logins. The result is that agent cannot perform the initial snapshot but you won't find this out until 50 steps later after Step 10 in the section €œCreate a new subscription".
To get back on track, openthe Object Explorer's Security section and add the snapshot_agent to your logins. Then using the "User Mappings", set an appropriate level for the SQLMobile database role. Once completed you then need to run the agent.
Right-click the SQLMobile publication you created and select "View Snapshot Agent status". From that dialog you can select "Start" to run the agent. When it completes, you can return to the tutorial section "Create a new subscription" and continue with the tutorial.
I am studying the tutorial in SQL Server 2005 Mobile Edition Books Online, and the topic is Creating a Mobile Application with SQL Server Mobile. I have got a problem when creating a new subscription after created a new SQL Server Mobile database. And the problem is shown below:
New Subscription Wizard
- Beginning Synchronization (Success)
- Synchronizing Data (100%) (Error)
Messages
* Failure to connect to SQL Server with provided connection information. SQL Server does not exist, access is denied because the IIS user is not a valid user on the SQL Server, or the password is incorrect.
HRESULT 0x80004005 (29061)
* 無法完æˆ?作æ¥ã€‚
- Finalizing Synchronization (Stopped)
- Saving Subscription Properties (Stopped)
Before I have met this problem, I have finished all the task. And I can browse the localhost web site by using anonymous account even I use internet explorer or browse the directly in IIS.
Does anyone can solve it?? Thank you very much~~~

Hi:
When I try and connecto to SQL CE I always get an invalid operation exception. I"m afraid that I did not follow the proper install for Orcas Beta 2. I can't remember if I was supposed to uninstall SQL Mobile 2005 first or not.
All I know is when I try and use my SQL CE I can't connecto to a DB / sdf file ?
Any help would be appreciated I"m just starting to use SQL CE.

we are currently using id's as primary key and replication is not part of our project.
will this be a problem if we decide to do replication? will microsoft generate an identifier then.
what is the advantages of using GUID now or doing it latter?
Hello,
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
I 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?
Thanks in advance.
Hi 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!
My 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>

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
Hi,
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
I use MS SQL Server 2005...Is there a structural advantage/disadvantage with using GUID as oposed to an integer?(also I use the sqltableprofileprovider and it doesnt seem to work with uniqueidentifiers)
View 6 Replies View Relateddoes SQL Server have the equivalent of the Identity or Scope_Identity functions that can be used to return the last GUID PK?
View 5 Replies View RelatedI 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?

I'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?

I 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 ?
Hi,Is there any replace for "Select @@identity" that could return "justinserted" GUID as a primary key?Has anyone tested what's faster, working with Guid or Autonumber ?
View 24 Replies View RelatedGreetings 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.

I 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?

once upon a time someone told me how to do this, but i forget, and it was for classic asp..
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?
Thanks

I need to execute stored procedure which is suppose to return GUID to my IF statement and if it is Nothing I execute other Stored procedures else some other procedures. My problem is that even though by looking at the data I know that after the execution of the procedure it should return some guid value it doesn't anybody who had the same issue??? That is the code block where I am trying to return guid from my stored procedure: getGroupID.Parameters("@GroupName").Value = dr.Item("Group ID").ToString() If getGroupID.ExecuteScalar() = Nothing Then 'Find Group by IP address if input Data Table doesn't have group getGroupIDByIP.Parameters("@IP").Value = dr.Item("IP").ToString() If getGroupIDByIP.ExecuteScalar() = Nothing Then insertGroup.Parameters("@GroupID").Value = Guid.NewGuid insertGroup.Parameters("@Group").Value = dr.Item("Group ID") insertGroup.Parameters("@ACCID").Value = getAccID.ExecuteScalar() insertGroup.ExecuteNonQuery() command.Parameters("@Group_ID").Value = getGroupID.ExecuteScalar() Else command.Parameters("@Group_ID").Value = getGroupIDByIP.ExecuteScalar() End If Else command.Parameters("@Group_ID").Value = getGroupID.ExecuteScalar() End If Thank you
View 2 Replies View RelatedDear SQL,
I need to SELECT something from a database that has a UNIQUEIDENTIFIER (GUID) field,
If the number is wrong (has some other than A-Z 0-9) than the ASP page just freaks out and gets "error converting from a character string to uniqueidentifier"
How can I check that the GUID is OK before I SELECT ?
this is the number format:
{7A9B5F81-4936-4A31-B4E2-9168AAB75A0}
I tried to cast this "error" number with no successs:
"WHERE Deceased_ID = cast('"& "---------4936-4A31-B4E2-9168AAB75A0" &"' as uniqueidentifier)"
Thanks in advance, Yovav.
