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

Uploading SQL Express To SQL Server 2005 - Role's Causes Application Error With SSE Provider

Jun 25, 2007

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: 
The SSE Provider did not find the database file specified in the connection string. At the configured trust level (below High trust level), the SSE provider can not automatically create the database file.
The ASPNETDB.MDF database was uploaded using the Database Publishing Wizard.
Please help!

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.

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,

MSSQL 2005 Express For Web Application?

Sep 10, 2007


I'd like to get the experts' advice on whether SQL server 2005 Express edition (SSE) is suitable for medium scale web applications.

I have looked through the reviews of SSE. From what I understand, its limitations over the MSSQL 2005 Standard are:

1. SSE limits database size to 4GB and memory to 1GB.
2. Support for only 1 CPU.
3. No analysis or reporting services.
4. No full text indexing
5. No SQL Agent.

I have a web application that is currently running on a shared web host with a shared MSSQL 2000 database. I'm thinking of shifting to a Virtual Private Server, where I can install SSE for free.

Currently my app has about 14,000 page views a month, and each of them pulls out data from the database. I don't use any analysis or reporting services, or full text indexing or SQL Agent (for now).

My questions:
1. Is 1GB memory sufficient for this type of application?
2. Is there any reason I should not be using SSE for my type of application?

Thanks in advance for the help.

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?

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.

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?

Moving A Database Application To SQL Server 2005 Express

Sep 13, 2006

I have been programming an application with VC++ 2005 and SQL Server 2005. I have converted an old 16-bit database to 32-bit managed code and SQL server and the application seems to be good. Now I want to deploy the application to another server for testing.

I have installed XP SP2, Windows Installer 3.1, Net framework 2.0 and SQL Server 2005 express to the test server. I have transferred the application with WI 3.1 and the program works well in the test server till the first SQL command. I have made a back up of the database and restored it in the test server. In the test server I can log in the database with Server Management studio and I can read the data there correctly. I have enabled both named pipes and TCP/IP for the database in the test server. With Surface Area Configuration I have enabled Local and Remote Connections Using both TCP/IP and named pipes. I only need Windows authentication at this time.

After all this when I come to the first SQL command in the application on the test server I receive the error message:
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 Could not open a connection to SQL Server).

My connection string to the database is:
'connection->ConnectionString = "Persist Security Info=False; Integrated Security =SSPI;"
"Data Source=TESTSERVER; Initial Catalog=TESTDATABASE;";'

When I use "Data Source=DevelopmentServer", the application works well on the development server.

Can't understand what is still wrong. Can you possibly have an answer for me?

Installing SQL Server 2005 Express As Part Of My Application

Jul 16, 2006

I have found a lot of info on MS site regarding installing SQL Server 2005 Express as part of an application. I have found these articles to be extremely inaccurate or at best incomplete.

1. The documentation says all I need is the setup.exe from SQLEXP but this is not true.

2. When I do launch setup.exe during my app's install, it fails because setup.exe trys to run the support.msi. Of course this causes failure because my install is also an msi.

So, does anyone know how to install SQLEXPRESS as part of my app's install?

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.

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.

Dim lconnectionString As String Dim builder As New SqlConnectionStringBuilder Dim cmd As New SqlCommand Dim reader As SqlDataReader Dim parameter As SqlParameter builder("Data Source") = ".SQLEXPRESS" builder("Initial Catalog") = "" builder("AttachDbFilename") = "C:My DocumentsVisual Studio 2005Projectsabcabcabc.mdf" builder("Integrated Security") = True builder("User Instance") = True lconnectionString = builder.ConnectionString Dim sqlConnection1 As New SqlConnection(lconnectionString) cmd.CommandText = "SP_add_collection" cmd.CommandType = CommandType.StoredProcedure cmd.Connection = sqlConnection1 sqlConnection1.Open()

Problem Migrating Application Database From SQL Server 2000 To Express Edition 2005

Jan 21, 2008

Hi there

I am new to SQL Server, but the current project that I am working on has the following requirement:-

1) Migrate the application (a servlet based web application on Apache Tomcat) from Solaris to Wintel
2) Migrate the supporting database from SQL Server 2000 to Sql Server 2005
3) Get IIS to communicate with Tomcat for serving servlet/jsp etc to the client

Though I successfully completed item 1 above, am stuck at item 2. Details are below

Actions taken for item 2

A. Installed MS 2005
B. Created new database in MS 2005 (logged in as user 'sa')
C. Generated SQL scripts (such as create table table_A etc) from existing MS 2000
D. Genearted SQL scripts (such as insert into table_A etc) from existing MS 2000
E. Created new schema in MS 2005
F. Ran scripts C & D in the new schema. All tables are records populated.
G. Obtained new JDBC driver and test run to see if connection is working fine, and it worked. Even ran an sql statment

Code Block[select count(*) from sa.table_A]

and got appropriate response.

H. When I made the application to talk to this new database (which is a copy of Production from step C, D above), it's behaving as though it cannot find the record.
I. When I further debugged, I realised that the web application is excuting queries without mentioning the schema. For eg.

Code Block[Select firstName, lastName from table_A]

Or rather it assumes that the user connecting to database is same as the schema name.

J. To further ascertain my point, I ran the query

Code Block[Select firstName, lastName from sa.table_A]

and it worked!

Now the real problem is that I cannot modify the existing code to append a schema name and this approach is rather not recommended best practise.

I tried to match the user name with the schema name, even made this schema as default to the user. But still not finding any luck.

I request all you experts out there to help me out with this problem.

ODBC Connection For Client Application To SQL Server 2005 Express Installed On Network Computer

May 5, 2006

Hi All,

I've developed an application that connects to a SQL Server 2005 Express database. I created a DSN to connect to the database through ODBC. Currently, I am testing locally and everything works fine.

I would now like to install my application on another workstation and connect remotely to the database located on my development machine.

The client workstation does not have SQL Server 2005 Express installed on it because I would just like my application to connect remotely by creating the DSN and using ODBC. What I'm missing here are the database drivers. The "SQL Natice Client" is not available on this client workstation. How can I deploy the necessary drivers with my installation file so that I may create the required DSN name using the SQL Native Client driver?
