Users/Roles/Schemas
Nov 27, 2006
I'm trying to find some documentation or procedures that will allow me to xfer existing users' roles, etc from sql2000 to sql2005.
When our sql 2005 database was restored on a new server (from sql2000), all of the database users were orphaned. I need to create identical server logins and then make the logins database users. It is also important to understand the significance of the new schema concept. The Microsoft SQL2005UpgradeTechRef.doc white paper does not explain any of this.
Ultimately, I would like to create a script for the above scenario once a sql2005 db is restored from a sql2000 db.
Could someone please help me out on this?

Hello,
I am new user of SQL Server. I have some problems with these words. I want to make my database works in my specified permissions. I will specify permissions with schemas and these schema wants an owner. I want this owner should be my user. When creating a user it needs a valid login. I am selecting my login and it occurs and error says this login has an different user. I am specifying permissions with roles. But i can't make association all of them. I hope i told my problem to you as well. If you explain these words to me and tell me how can i do my database's works with my own schemas, users and roles i'll be grateful. Thanks for advices.
Happy coding...

Sql 2005
I want to grate execute permissions on my stored procedures to a role. While creating the role, it asks for "schemas owned by this role".
To me, the schema is merely a namespace that allows you to group objects, but arent schemas such as db_datawriter roles that are central to the db and only admin type users should have ownership of these, correct ?
In a nutshell, I want to:
create a new role and assign a user to that role
with a stored procedure, grant execute permissions to this role
I was confused by the sql 2005 dialog that asks me to take ownership of roles such as db_datawriter, db_datareader etc, wouldnt that mess up other things with the database ?
help ...
I think its time I review all of the above items
role
user
login
schema

I have been struggling with this for a while and cannot get it right. I have read countless articles on the internet as well as MSDN documentation about SQL Server 2005 and no success so far.
What I want is a database with multiple SCHEMAS, DATABASE ROLES and USERS in order to have a finer grade of security to access the various objects.
My schemas are (in order to simplify the situation and provide an example of the setup):
- [dbo] the standard DBO schema which is always default. Contains public objects.
- [com] a special module integrated into the system
- [ofc] contains objects used by back-office only
- [aud] contains objects used for auditing, etc.
Each of these schemas has their fair share of tables, views, functions and stored procedures which have been created appropriately (i.e. CREATE TABLE [ofc].[Addresses]), in other words prefixed by the name of the schema to which they belong.
Then I have created various database roles (don't confuse them with SQL2005 application roles) as follows:
- PublicRole mostly used for viewing, no data alterations
- WorkerRole used by front end processes that need write access to data in [dbo] and [aud]
- OfficeRole used by back-office for dealing with backoffice data (basically [ofc], [aud] stuff)
- AdminRole used by application administrator
Each of these database roles has been defined with owner 'dbo', none of them own any schemas. And last but not least to each of these roles I have selected the above named schemas (dbo, ofc, aud) as securables and for each of those securables schemas I have then given the correct set of GRANT/DENY on the Alter, Control, Delete, Execute, Insert, References, Select, Update, Take ownership and View definition.
As an example, the PublicRole role has been given the following permissions (Y=GRANT, N=DENY):
Table #1 of Application Permissions [dbo] [com] [ofc] [aud]Alter N N N N
Control N N N N Delete N N N N Execute Y Y N Y Insert N N N Y References Y Y N Y Select Y Y N Y Update N N N Y Take ownership N N N N View definition N N N N
And I have the following minimum set of database users defined (the server login has the same name):
- upublic, assigned to PublicRole
- uworker, assigned to WorkerRole
- uoffice, assigned to OfficeRole
- uadmin, assigned to AdminRole
As I understand when I assign these users to a particular custom Database Role, the users inherit the permissions granted to THAT role thus liberating me from having to assign the permissions to each and every user account on the same role.
What I expected was that when I logged in to the database with the upublic user account I would at least be able to view (SELECT at least) ALL the objects with the exception of those in th e[ofc] schema. Unfortunately the account is not able to access ANYTHING at all, I get an error like
"The SELECT permission has been denied on object XYZ, database DB, schema 'dbo'"
So, when I use Management Studio to look at the properties I selected the PublicRole and it showed the upublic user as a member of the role (Members of this role). So far so good.
Then when I switch to the Securables page for this role it shows all the schemas I defined and for each of them the same list shown in Table #1 except it has two lines for each permission, the first for Grantor dbo and the second for Grantor upublic. The first has the same permissions I assigned to the role (as shown on Table #1) but the 2nd does not show a checkmark on either GRANT or DENY!!! For example ([x] = checked, [ ] unchecked):
Table #2 Explicit permissions for Securable
Permission Grantor Grant Grant-with Deny
Select dbo [x] [ ] [ ] Select upublic [ ] [ ] [ ]
What am I doing wrong here? Apparently I then have to repeat the whole grant/deny for EACH and EVERY USER I define when the idea was that I would grant/deny on the database role and every member of that role would inherit those permissions automatically.

Hi,
I am looking for some advice on securing a sql 2005 database.
I have a database to which I want to grant 3 different users access.
The first users, who we will call 'public' should have access to a set of stored procedures, and no access to tables without using the stored procedures they have access to.
The second users have again got access to a certain set of stored procedures, along with the stored procedures for 'public'. These should be called 'moderator'.
Finally the third set of users 'admin' should have access to all stored procedures, but again no access to the database unless its through a stored procedure.
Questions :
Using SQL 2005, how do I assign access to particular stored procedures to a user?
How do I ensure that a 'user' cannot access stored procedures I don't want them to access?
Some of the stored procedure use dynamic sql within them, will this affect my setup. If I deny direct access to the tables to all three users, but allow them access the stored procedures, can the stored procedures access the tables?
If schemas are the answer, how on earth do I set them up, Ive never seen something so badly documented online in my experience! In my development environment im using sql express, so will probably working through the query analyzer.
Thanks in advance.
Conor

Hi,
I've a Problem with a Function called by different users.
I want the different callers to query a table in their own default Schema.
So if i refence the full Path [Schema].[Tablename] it works Properly.
If i just Use the [Tablename] for reference it fails.
The function was created with EXECUTE AS CALLER option ;
if I call it with dynamic SQL i retreive the error-message
"Only functions and extended stored procedures can be executed from within a function."
does anybody know a solution for this problem?
thanks in advance

Hello,
I think now MS SQL 2005 support packaging database object into schemas which may be granted access by any of the db users, while SQL 2000 only we could use the database creator user instead of schema. my case is i am working in a system with more than one module, e.g. HR + TaskManagemt.
Both HR and TaskManagement objects are in the same database, and there are some common objects.
I want to isolate the HR objects from the TaskManagemt objects, so i can package any module separated from the other, suppose i want to buy only the HR module, so that i want only to exctract the HR Object + the common objects but not the TaskManagement objects.
So how can i accomplish such operations using SQL 2005 schemas AND using SQL 2000 users.
P.S. i have two servers one with 2000 and the other with 2005, so i want to find solutions for both 2000 and 2005
Thanks in advance

Guys,
I have 2 users emp_rw (read write) and emp_ro in the database through which application accesses the database.
Now I would like to replace this users with roles and assign emp_rw, emp_ro to roles. Which roles should be created -
database roles or application roles what is the difference between application and database roles.
currently I execute the below statement to grant rights on database objects to emp and emp_ro users, can this be changed
to grant rights to role instead of user.
grant execute on <function name, procedure name> to emp_ro
Any suggestions and inputs would help.
Thanks

Hi, all. I've got a question that's truly newbie. I've added logins to the "users" of a database, but I've never used the "roles" area. What's the difference? Is a role like a group account with some preset permissions?

Hi everyone out there in ASP.NET land.
Have a quick question...
How do I add a role and/or a user through code (Specifically SQL Statements). If not through SQL, then maybe VB.NET?
Thanks ahead of time,

Hi there NT Server,sqlserver 7.0, Integrated Security. I used "sp_attach_db" to attach a database to the sql server. The database has 3 standard roles with members in each of those roles. But i am not able to add a user to any of the roles through Enterprise Manager(No users are listed, except the other 2 roles). Also when i click "users" under the Database in EM, no users are listed except "dbo" with sa login. Luckily since some members are there in the roles, they are able to connect to the database. Also i am not able to add the user bcos the user exists in the public role and i get an error message "user already exists in DB". The user has logged into the NT and everything is fine. I copied the .mdf and .ldf files from a "Standard Security" Server.

SHORT VERSION
i am setting up roles, do i also have to set up role-people as users?
LONG VERSION
my db has two owners. both of us run the Access front end happily - everything works perfectly.
now i'm trying to add non-owner users.
i have set up ten people as datareader/datawriter (primitive, but will refine this later).
these people are not able to get into the db.
at the registering DSN stage they can't see the server in the list of servers and if they manually type \myserver they can't connect (doesn't exist or access denied).
in Enterprise Manager,
Users: shows only the two owners
Roles:datareader shows the ten non-owners (ditto datawriter)
am i supposed to setup my datareader/writers as users as well?
should i see them in the Users: list?
thanks for your time.

I have developed a site on my local machine utilizing the built-in security/roles provides by ASP.NET 2.0. I am trying to publish the web application to a production server. It will publish correctly, however the ASPNETDB is not recognized. The folder app_data is created with the proper database files. My question is how do I set this up to use the data I have created in this database? I've searched on how to accomplish this but haven't found any definitive answers. I have found ScottGu's blog to be useful, but I was wondering if there is a different way.
1 - Do I push the data to a SQL Server install via SQL scripts?
2 - Can I link to the ASPNETDB that is created locally on my machine?
3 - If I make changes to the application and re-publish, is there a way to keep from overwriting the ASPNETDB on the server?
I am a unsure of how the built-in roles/security works when you are ready to push something to production. If someone wouldn't mind pointing me in the right direction, it would greatly be appreciated. Any literature, advice, links, etc.. would be great.
- Thanks
Andrew

I am in need of a utility (stored procedure, third party app, etc)that will help streamline the process of managing and auditing objectpermissions, users and roles on multiple sql server 2000 instanceswith multiple databases on each instance. That's a quick overview ofwhat I need, do I need to be more specific?Thanks.

A question on the permissions hierarchy:
Since logins, database users, and database roles are both principals and securables - what does it mean to GRANT permission on a login/user/role to another principal? Does it mean that for a login - you can GRANT permission to EXECUTE AS that login or modify it, for example?

Developers need to view and modify jobs on some servers without being sysadmin. We've added the developers to the following MSDB roles:
SQLAgentOperatorRole
SQLAgentReaderRole
SQLAgentUserRole
Technically they should be able to view and modify jobs through Management Studio when being added only to SQLAgentOperatorRole. However they receive the following error when clicking on the Jobs folder regardless of the msdb role.
Execute Permission Denied on Object 'xp_sqlagent_enum_jobs', database 'mssqlsystemresource', schema 'sys'. (Microsoft SQL Server, Error: 229)
Our original two SQL 2005 servers do not produce this message, but all other instances do. All servers, but one, are SP2 so the service pack is not an issue. Any thoughts?
Thanks, Dave

Can you write a stored procedure to add a user to your DB and set the roles the user belongs to?
I want to write a stored proc. to add users and set roles so it can be used in code instead of doing it manually.
After the user has been added and their roles set, can you write another stored proc. to give you what roles they belong to?

Apologies if my post does not fit into this forum. I initially tried the SQL Server Data Access forum but I now think my question is more security related.
Is it possible for a web user who has been successfully authenticated with forms authentication to be authorised to use a SQL Server 2000 role depending on a particular ASP.NET 2.0 role that they have been authorised to use? I understand that that I can assign a SQL Server 2000 role to the ASPNET or NETWORK SERVICE account but this will grant access to anonymous web users to the database role. I can ensure that I only call stored procedures which access sensitive data in web pages that are in restricted by ASP.NET roles. However, it would be nice to also restrict stored procedures via the ASP.NET 2.0 Forms Authentication roles.
If this is not possible have you got any bright ideas how I could restrict access to stored procedures who are anonymous web users.
Many thanks,
Mark

I'm developing an ASP.NET2.0 application which accesses a SQL Server 2005 Express database. I plan to use integrated security for access to the database.
I'm confused about the relationships between Windows groups, the ASP.NET web.config file <allow roles=.../> and SQL Server roles.
I would like to create a Windows group to which I can assign multiple users and grant that group access to a Web Site using windows authentication and also grant that windows group access to the database my web application uses.
I have gotten the combination of Windows Authentication to the web site and to the database to work for a specific windows user but I am having trouble determining the combination of database security entities I must create to allow access to my database by members of the windows group.
For a Windows user:
1. Create Windows user
In SQL Express
2. CREATE LOGIN FROM WINDOWS WITH DEFAULT_DATABASE =
3. CREATE USER FOR LOGIN
4. CREATE ROLE
5. EXEC sp_addrolemember <role-name> <user-name>
For a Windows group, what would be the equivalent commands necessary to grant a windows group access to my database? Specifying the Windows Group name in sp_addrolemember does not appear to be sufficient even though the documentation states that a windows group name is a valid value for the member name argument.

After reading Books Online, I am still confused with Database Role vs Application role.
My intention is to control the end users' authority on the database, where the end users will access through Winforms client application. With proper assignment of schema and database roles to an user, I believe this will enough to control the permisison of an user.
If this is the case, why Application role exists? When and why should I use Application Role? How is it different from Fixed Database Role?

I am in the process of locking down the SQL Server in an environment that is considered to be in production (pilot stages) and there is no staging or test environment that mirrors it. I need assistance in determining the server and database roles to assign to existing logins, most of which currently have sa and dbowner rights. Because it is not a development environment, I need to be sure that downgrading the server and/or database level permissions will not break any functionality.
I'm starting with the logins that have the SA fixed server role. These logins need to be able to install applications that require the use of a backend database, which will be stored on SQL Server. In addition, through the installation process a new login/password for the newly created database(s) is normally created. For the existing logins with the SA fixed server role, will downgrading to the securityadmin and dbcreator roles be sufficient to facilitate those needs, or are those too much/ too little? And should any user account ever be granted the SA role? If so, what questions could I ask to determine this need?
Since these install process for these applications usually prompt to install using SA or local system account to authenticate to SQL to create the new database(s), that account should have securityadmin and dbcreator roles to create the database and its tables, as well as add a new login to that database.
Please address this question, keeping in mind that the logins will only be performing the described actions, installing apps using SQL Server as the backend database and adding a login to that database (which may or may not be done during the installation process).
Thank you,

Hi,
I'm looking for some guidance/help regarding setting up a sa - lite account in SQL 2005. I need to give another admin rights to create/monitor maintenance plans, backup and restore databases, monitor performance/logins, but NOT be able to have any rights on several tables (and of course not being able to set user permissions).
I've tried using server and db roles but haven't been able to determine how to give someone w/o full sa rights access to maintenance plans.
If you can think of soemthing, please let m eknow.

I have MS SQL Server 2000 DB.
I have created a User and created some tables for the same.
I created a Role named A and granted Select Permissions for few tables to that roles.
When I created another Role named B and added this role (A) to B, the permissions are not being xferred to B. Bcos of which, if i assign an User to Role B, he is not able to select the tables for which permissions have been given thru role A.
Note : If i give assign directly the user to Role A, it is working. But i want to assign User to role A only thru B.

We have an existing SSRS server, and have just created a new child domain. We'll be migrating users from the parent to the child, and want to add the users of that new domain with access to SSRS. In the parent domain they are able to access, but after migration with the child domain account, they cannot.
I have added the group CHILDDomain Users with a system user role on SSRS, and PARENTDomain Users was already there.
Is there any additional step I should/could take to get this active?

at the meantime, i've a search-page where i can fill a form to search users. in the dropdown to select the country i included an option which is called "all countries".
now the problem is: how can i make a stored procedure that makes a restriction to the fk_country depending on the submitted fk_country parameter?it should be something like
SELECT * FROM webusers(if @fk_country > 0, which is the value for "all countries"){ WHERE fk_country = @fk_country}
who has an idea how to solve this problem?
