SQL Server 2005 Application Role's Problem

Oct 8, 2007

Hi all.

I have developed a VB6 program which will activate an Application Role to UPDATE and INSERT some tables in SQL Server 2005.

My program will login with a username, say USER and then run with the rights of the Application Role which will SELECT, UPDATE and INSERT the following tables:
1) Table A
2) Table B
3) Table C

The USER login is a restricted user which has only SELECT permission to Table A, B and C.

I encounter a problem in which my program can only UPDATE table B and table C but Table A. I have double checked the settings of Table A, Table B and Table C. Theirs are all same. Fyi, the column which can't be updated is of type "datetime".

Once i grant USER login UPDATE permission to Table A, my program works perfectly in which it can UPDATE all the tables including Table A.

I have tried for almost 2 days but am still clueless. Any ideas?

Thank you so much.

SQL Server 2000 And 2005 - Application Role - Sp_setapprole

Jul 24, 2006

Hi All,

Is there any limitation for setting password to an approle (like it should be 8 character long, should not start with numbers) ?

If so, what are those limitations ?

Does the same is applicable for sp_setapprole which uses the same password ?

please confirm, for both SQL Server 2000 and 2005 versions.

thanks in advance,

I am very frustrated.  Everything works on the local host but when I upload to server I can login to the admin role I created, but when I try to access pages that have role priveleges I get the following error:

Application Role And SQL Express (2005)

Feb 4, 2007


Can I confirm whether pooling=false in the connection string is still required for SQL Server 2005 (Express Edition)?

Various google searches say pooling has to be turned off for SQL Server 2000, but I was just wondering whether it is still a limitation for SQL Server 2005

Sending SQL 2005 Dbmail When Using Application Role

Jan 16, 2007

I am attempting to use dbmail from an application that logs in to my database using an application role.  Since the application role does not exist outside the database, I created an spSendEmail in the database with "execute as login='mailagent'" in it:  I set the database to trustworthy, created a 'mailagent' account and added it to the msdb database with the databasemailuser role rights.

Email works just fine on the server when I use the execute as login='mailagent' to fire off the msdb..sp_send_dbmail.  But from the .NET application, I get the error: "Cannot execute as the server principal because the principal 'mailagent' does not exist, this type of principal cannot be impersonated, or you do not have permission."  When I run my spSendEmail stored procedure from the calling database, I get the same error.

Also , If I was to use the application of Power builder , using app role , how do control which user can use the app ?

Troubleshooting A New Application Role

Mar 1, 2001

Hi all,

This one is a real X FIle, just without Mulder, Scully or the Lone Gunmen!

I have a database, to which access must be restricted via a sole application. So, I have to use an application role. I go in the database and run these statements to add and activate the roles, respectively;

Exec sp_addapprole 'Sirius', 'password'

(The system confirms the role is created.)

Exec sp_setapprole 'Sirius', 'password' 'odbc'

(The system confirms the role is activated.)

Right, now I should not be able to connect using anything but this role, agreed? But here's where things go wrong. I can then successfully connect from another computer by using MS query from Excel, from a login that is not even a member of the Public Role!

I tried again, started and stopped the Server/DTS/Agent services and dropped the old role after each successful login before recreating it. I've checked my syntax exhaustively. I must be doing something wrong, or overlooking something, otherwise MS has a major security problem! (Just hope the Cancer Man doesn't find out!!)

Thanks in advance everyone,

Application Role And SSRS

Sep 7, 2006

Hi dear reader

I made an application that uses a Sql Server 2005 Express DataBase.

In the database I made a application role.

When the user logs into my application I run this procedure:

If Not sqlConnectionCR Is Nothing Then

If Not sqlConnectionCR.State = ConnectionState.Open Then



ConsultasSqlCommand = New SqlCommand

ConsultasSqlCommand.CommandType = CommandType.Text

ConsultasSqlCommand.CommandText = "sp_setapprole 'appRole', 'drowssap"

ConsultasSqlCommand.Connection = sqlConnectionCR


End If


I understand that this procedure connects to my sqlserver database as my application role

Ok, so far no problems in reading and manipulating data.

The problem comes with the reports in my application. For example: I have a reportviewer with a serverreport but when I try to show the report gives an error about permissions and grant access....

I think that is because the Server Report uses the user account (domain/user) to read the database. No user (besides admin) has access permissions in the database (only admin and application role).

So, my cuestion is: How can I tell Report Server to use the application role to display reports?

Thank you for your time and help.

Security For Application Role

Sep 4, 2007

We have an application use Approle to read from database. If the client login to windows as administrator or a name that has the administrator rights, the application can get all data. If the client login to windows as a domain user that has limited rights, the application can't get all data.
I run profiler and found that it seems, when application use approle to access a database, the login name is the domain user that log into windows. Is there anybody know what type of right the window login name should have in order to get all data from a database?

Second question, when I log in to window as domainusername( username is not administrator, but has administrator rights). In the profiler, I can see the application use this domainusername access database. However, under sql server login node, I didn't find domainusername. Is this because, the domainusername belongs to buildinadministrator?

Application Role Losing Connection?

Sep 6, 2007


I'm testing the use of application roles for security. The customer I work for has still a lot of ASP intranet applications running. We're migrating the databases to a SQL Server 2005 server.

I've changed the connection string to a user without any permissions but to log on. After that I use an application role for permission to select different tables and to execute Stored Procedures.

The first queries do execute but after that I get "Permission denied", like I haven't got the application role anymore.

Any ideas?

Login Failed For 'user' (Application Role)

Oct 16, 2006

I've created a database in SQL Express and I have a Windows form attempting to connect to it through SQL Authentication. Connection string:

private string connString = @"Data Source=.sqlexpress;Initial Catalog=SQLTestDatabase;User ID=SearchAppRole; Password=password;";

The role I have added to the database is an Application Role. It has been added to the Database permissions with Grant checked for "Select" and "Authenticate".

If I test this with query analyzer, it returns expected results (if I remove Grant from 'Select', it fails)

sp_setapprole 'SearchAppRole', 'password'

select * from recipe

If I edit my connection string (for testing purposes) to use the sa account, the application can connect and run the Select statement:

private string connString = @"Data Source=.sqlexpress;Initial Catalog=SQLTestDatabase;User ID=sa; Password=sa_password;";

However, I cannot get the application to successfully logon and run the select statement when using the user id and password of the Application Role. I get error:

System.Data.SqlClient.SqlException: Login failed for user 'SearchAppRole'. at System.Data.SqlClient.SqlInternalConnection.OnError(SqlException exception, Boolean breakConnection) at System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning(TdsParserStateObject stateObj

I can't find much information on Application Role...I just want one basic permission for the application as a whole. Any help is appreciated. Thanks.

Feb 17, 2006

Running VB 2005 Express Edition and Sql Server 2005 Express Edition (SQLX).

Developing a desktop application which calls a local instance of ".sqlexpress".

This app needs to set data base options and add/del various table columns.

When activating the application role, I get the following message:

HariCari SQL Error/s 15422 - Application roles can only be activated at the ad hoc level.

Anyone know what this message means?

I have searched SQL Server Books On-Line and been unable to find a list of Sql err numbers. Either I have missed the obvious or Books On-Line has missed the obvious.

Application Role How Query A View Whose Reference Table Is In Another Db?

Aug 23, 2007

Hi everybody.
I created an application role in a database (DB1) and gave it all the rights on a view in DB1 which refers to a table located in another db (DB2). I also gave the rights to the app role on a table of DB1
I tried to use this app. role through the sp_setapprole launched by a user (server principal?) which is SQL Server administrator (and local administrator (Win 2003 Server)).
With the following query

I see that the approle is being used.
Than, if I query the table on DB1 everything works, but if I query the view, referring a table in db2 I get following error:

The server principal "NameOfServerPrincipal" is not able to access the database "DB2" under the current security context.
What should I do to make it work?

The table in DB2 has the same schema of the view in DB1 which refers to it.
I put the DB1 TrustWorthy and both the database have the db_chaining option activated.

Any idea on how to solve the problem would be widely appreciated.
Thank you very much.

Can't Make Database Role A Member Of Another Database Role In 2005.

Jan 9, 2006

In sql server 2000, I created some custom database roles called ProjectLeader and Developer.  I would make these roles a member in the fixed database roles so that I would only have to add the user to the ProjectLeader or Developer role once and they would presto-magico have the security I wanted them to have with no unecessary mouse clicking.  I'm not sure how to repeat this process in 2005?  Management Studio doesn't seem to allow you to add a role as a member in another role.  Is there a work around or solution for this?

SQLCe Errors When Doing Developing A SQL Mobile Application With Visual Studio 2005 And SQL Server 2005 Tutorial

Feb 26, 2008

I'm attempting to use RDA to synchronize a pocket pc emulator with SQL Server 2005 database by following tutorial http://msdn2.microsoft.com/en-us/library/aa454892.aspx, which uses AdvWorksMobile database that comes with SQL Server 2005.

When get to testing of "To test application features " ( step 4 of the merge replication setup lab ), I am receiving SQLCe Exception errors.

ORIGINALLY, I was able to deploy an application and view the local database on the emulator, but once I clicked "InitSinc" button, I received an error.

"Failure to connect to SQL Server with provided connection information. SQL Server does not" exist, access is denied because the SQL user is not a valid user on the SQL Server, or the password is incorrect.
Found this error listed in Server Agent Errors log http://technet.microsoft.com/en-us/library/ms172357.aspx, but it wasn't very helpful since it doesn't provide any suggestions on fixing the problems.

I am brand new to SQL CE Server , mobile programming and .NET framework in general so please bare with me

All the connections / security settings, etc that were set up were taken from a tutorial so I am not sure what SQLCeServer is complaining about. Reading up on the error on the web didn't help, it all pointed to making sure that the snapshot folder had correct permissions set up. I verified that MACHINENAMEUISR_MACHINENAME guest user had Read rights to the database so I don't think that piece is the problem. Otherwise ,Merge publication has been setup in Microsoft SQL Server Management Studio by following the tutorial.

I am trying to run this sync on my home pc so there should be no issues with any user permissions

I have IIS installed

I did NOT have SQL Server Agent running in management studio at this time

I am trying to run this tutorial on an XP machine, which is my regular home PC so I dont think there are any special networking settings to consider

I am able to hit http://localhost/AdvWorksMobile/sqlcesa30.dll from my pc OK, but when I try to hit it from a cradled emulator ( after replacing "localhost" with "MACHINE_NAME" ), Internet Explorer on the emulator gives me a "Cannot Connect With Current Settings" error message. This part wasn't part of tutorial but decided so not sure if I am supposed to be able to hit it from my emulator..so I am not sure if the fact that I can't hit it is related to the problem.
AFTER STARTING SQL SERVER AGENTin Microsoft SQL Server Management Studio, I killed the application, and after relaunching it, it hits "The Specified table does not exist [Vendor]" error. This time it doesn't even launch first - that is I dont even get to pressing "InitSinc" button. Debugger is showing that this error is hit on the following line in AdvWorksMobile.AddWorksDataSetTableAdapters

int returnValue = this.Adapter.Fill(dataTable);

I am not sure why the errors changed on me after starting SQL Server Agent.
What can I do to fix this connection problem?

Thank you so much for your help!

Can't Connect To Sql Server 2005 From My Asp.net Application

Apr 3, 2006

I can't connect to sql server 2005 from my asp.net web page. I seem to be able to connect to it when i run the application from within visual studio but i can't connect to it when i run the application from IIS.I am new to sql server 2005 express so please bear with me.The error message i get is: Cannot open database "Vets" requested by the login. The login failed.Login failed for user 'OSCAR2K4ASPNET'.I don't know where this user OSCAR2K4ASPNET came from but i looked in sql server 2005 and there he is. In the left hand pane I went to Security and then logins and found oscar2k4asp.net there. I went to the properties for this user and went to User Mappings. There was no tick next to my Vets database so I added one and ran the application from IIS. I also added the user to every single role in the vets database (including dbowner). I also went into the vets database itself and found the oscar/aspnet user and made sure he was added to every role.
I ran the application again. This time i got a lots of different errors. If the page was trying to run a select procedure I got the error user does not have select permission. If the page was running an SP i got the error or user does not execute permission
I have never had this problem before so I don't understand.Where did this user come from? Was he created automatically when i configured my database for membership and roles? How do i set up this user so he can access the databsae from IIS.
The only way I could get the application to run from IIS was to go to Security - Logins for sql server and add the oscar2k4asp.net user to the sysadmin role.
I find this very strange. Naturally i don't want to leave oscar2k4 in sysadmin.
Please help :) I can't upload my website until i fix this
Thanks, andrea

Problem In VB6 Application With SQL Server 2005

Apr 2, 2006

I have got a VB6 application where I update local SQL server table from MS Access table with code like that:


Dim rst As ADODB.Recordset
Set rst = New ADODB.Recordset
rst.Open "SELECT * FROM Table1 WHERE [Fld1]=" & v1, Cn, adOpenKeyset, adLockOptimistic
'check if exist if not exist create new
If rst.EOF Then
rst("Fld1") = v1
rst("Fld2") = v2
End If


On rst.Update I have got an error message that the server has to be added to syservers as linked with stored procedure sp_addlinked srever. Why?

Anyhow I executed the stored procedure then I've got error message 16933, "The cursor does not include the table being modified or the table is not updatable through the cursor."

I had to rewrite the code to "INSERT INTO (Fld1, Fld2..." and it works.

Is something wrong in SQL Server 2005 installation or any other reason?

Please help.

Isn’t everything fine with that? I created the table by host but dosen’t work. I’m wondering if can I conect straight with Data Base, without register in the server, like with mdb?
This is the error that I’m getting.

How To Get A Web Application To Connect To SQL Server 2005 Express

Dec 12, 2006

I'm a newbie here so forgive me if I have missed something completely obvious.
 I have bought a shopping cart script of a well known company (Evolve Merchant 5) and I wish to set it up locally on my development server, I created a virtual directory, set the web application up and get the asp pages to display perfectly. However, in the configuration file (global.asa & web.config) for the application it reguests information to be provided: <add key="DBName" value="Database name" />
<add key="DBServer" value="IP address of server" />
<add key="DBUserName" value="User name" />
<add key="DBPassword" value="password" />
<add key="AltPassword" value="password" />

 What I can't determine is what the SQL Server 2005's IP address is? the pages of this application show when I type http://localhost/catalogue into IE, so I presumed the server address would be the IP of localhost, when typed ping localhost into command promt it gives me, but when I enter this into the config file and try to load the application it just hangs and then eventually says:
"Microsoft OLE DB Provider for ODBC Drivers (0x80004005)[Microsoft][ODBC SQL Server Driver][DBNETLIB]SQL Server does not exist or access denied./catalogue/global.asa, line 54"
I have created a new database in SQL Express called: merchant509 and restored the tables to it as the manufactures help files state, I created a new login called shop which uses SQl authentication, so as I can provide a password. So the settings should look like this:
  <add key="DBName" value="Database name" />
<add key="DBServer" value="" />
<add key="DBUserName" value="shop" />
<add key="DBPassword" value="1684" />
<add key="AltPassword" value="1684" />
But it doesn't work, does anyone know what i have done wrong?? the SQL server is runnign on the same computer as I am trying to access it from, it is set to accept all forms of comunication i.e. TCP/IP etc.. in the server configuration manager the IP address part of TCP/IP in protocols shows IP1 as active yes enabled yes, and IP2 as active yes and enables yes, I have tried the and this gives the same errors, this is my registed IP on my home network.
 I'm now stumped, I haven't a clue what else I can try, I would be very greatfull if anyone has any ideas.
