Permissions For Objects Accessed Through A Stored Procedure.
Apr 24, 2008
While trying to execute a stored procedure I am getting error that 'SELECT permission denied on table .......' The DBA has given execute permission for the sp and still the same error. What needs to be done. When permissions are given through the SP it implies that the objects are given permissions ?
Putting in db_datareader group will give permission to read from all tables across all the databases in the server. We want that the user should be able to read data from only those tables called in the sp. Normally in SQL 2000 we used to give EXECUTE permissions to the sp only. This in turn would be enough for that user to get data while executing the sp.

I need to understand the permissions that a CLR stored procedure needs when it accesses tables. In a dbo TSQL stored procedure it has owner permissions on all dbo tables, so there is no need to grant permissions on tables to the database user.
Some developers recently implemented a CLR stored procedure that returned an error with update permission denied on table name. Once I granted the user account update permission on that table, it was able to execute OK.
I have been looking for a good explanation for the way the permissions to database objects need to be setup for CLR stored procedures. For example, could I have said to modify the procedure to use the EXECUTE AS clause, instead of granting the user account direct permission on the table? Does anyone have any links to good articles on this subject?
Edit:
I have a feeling I'm on my own trying to figure out how this works. I've been searching the web for hours, and I haven't found anything that directly addresses this.

Hi
I am having a problem with a particular stored procedure in a database application and I have ran out of ideas as to what is the cause. When calling this stored procedure from a .Net application it typically returns results in about 0.2 seconds. 24 hours after it's creation, the procedure takes over 40 seconds to return the same results to the application. However if I call the procedure via Management Studio or Query Analyzer, the performance remains consistently fast.
It's a fairly complicated query making use of the following features:
FOR XML EXPLICIT
The ROW_NUMBER function
Input Parameters
The procedure is replicated, along with the tables that it references
The calling application is using ExecuteXMLReader to retrieve the results.
To fix the problem, I can simply run an ALTER PROCEDURE statement (without changing any of the contents of the stored procedure). However, by the next morning, the problem will have reoccurred.
Can anyone shed any light on why this is happening?
Phil

The goal is to address visual source safe database on the network. We have the srcsafe.ini in the network as \ipaddrsrcsafe.ini. Now I create a new VSSDatabase object and call its OpenDb. Well for simple consle app or winform it is ok. But I was running it under Sql server Stored Procedure. It failed for I cannot access the source safe path throgh the COM object.
I know it is because of Windows identity. So I add the following code before I want to open the database, changing the to the WindowsIdentity:
WindowsIdentity impersonId = SqlContext.WindowsIdentity;
WindowsImpersonationContext orgCtx = null;
try
{
orgCtx = impersonId.Impersonate();
VSS_Database = new MVSI.VSSDatabase();
// VSS_Database.ImpersonateCaller = true;
VSS_Database.Open(Path, UserName, PassWord);
}
catch (Exception err)
{
orgCtx.Undo();
throw err;
}
finally
{
orgCtx.Undo();
}
Without the commented line "// VSS_Database.ImpersonateCaller = true", this does not work at all. It just behave like no changes to the windows identity.
However if I add this code, well, OpenDb will result in a No-response query. The Sql server is running the query with no responses.
Have you ever met that before? I am really frustrated. Thanks

Hi,
I want to manage memory relational data in the memory(Insert, delete, return) and manipulate the data via SQL 2005 and CLR database objects.
The gool is to manage a table that relatively has a lot of inserts and deletes which takes a lot of IO operations and i want to reduce it. the data itself is not permanant each row deleted from the table after 15-20 minutes.
I looked at the extended stored procedure and other CLR enable objects and it seams that they all return data from the database itself.
How can i return data that is reside in the memory?
Thanks.

Hi All, I am trying my hand at SQL CLR. I want to know one thing which I'm not able to get from anywhere. Suppose I've a C# class like Student. I create an object of this class and push its values into database. Instead of pushing individual property values to database I want to pass the Student object itself or maybe an array or list etc. Kindly help me if it is possible.
Regards

Hi Frens,
Could anybody tell me how can I find all the database objects that are used in /referenced by/called by/dependent on a given stored procedure? In other words, I am looking for something like a stored procedure or a function that takes as input the name of a stored procedure and outputs all the names of the tables, functions, procedures, cursors and etc. database objects that are used in that procedure. Could you please give me suggestions or possible answers for this?
Thanks a lot for your time.
Regards,
-Ram.

I have revoked an update stored procedure permission to a SQL user. The first time the user tries to execute the stored procedure he gets the error "Execute permission denied." But if he attempts it a second time the stored procedure will execute with success. I want to deny the user EXEC on the stored procedure forever. Does anybody have any advice to make this happen with success? Thanks.

I have created a Stored Procedure that will not insert into a particular table.
Yet, when I run the same code in Query Analyzer it runs as it should and completes the Insert.
I have tried to both recreate the SP and searched for authorization issues, with no luck.
Any suggestions?

Help!
I usually use SQL 2000 at work but upon deciding to work from home have installed and setup SQL express 2005. I use the management studio to write table and sps but for new sp I cannot find how to allow permission. I have been able to allow permission for all sps on the database I restored that I am now working on and have successfully allocated permissions to a new table but cannot do the same with the sp. The sp is viewable in the database but permission is denied when attempting to execute via my ASP script.
Any ideas??
Error Type:
Microsoft SQL Native Client (0x80040E09)
EXECUTE permission denied on object 'procBannerSlotList', database 'HotLizardWebsite', schema 'dbo'.

Okay, I have sort of a peculiar permissions question I am wondering if someone can help me with. Basically, here's the scenario...
I have a CLR stored procedure which does some dynamic SQL building based on values sent in via XML. It's a CLR stored procedure using XML because I want to build a parameterized statement (to guard against SQL Injection) based on a flexible number of parameters which are basically passed in the XML.
The dynamic SQL ends up reading from a table I'll call TableX and I actually discovered an (understandable) quirk with security.
Basically, the connection context is using security for a low-privilaged Windows account ("UserX") and UserX has no permission to the table referenced in the dynamic SQL but because of the dyanmic nature of the query, the stored procedure ends up adopting the security context of UserX. Naturally, this throws a security exception saying UserX has no SELECT permission on TableX.
Now, I can give UserX read permission to the table in question to get things running, but one of the points of using stored procedures is to defer security to the procedure level vs. configuration for tables or columns.
So in striving toward my ideal of security at the procedure level, my question is what is the best way to allow minimum privilege in this case?
I thought about having the internals of the CLR stored procedure run under a different (low-privalaged) security context, but I am wondering if there's an alternate configuration that may be as secure, but simpler.
PS - Please don't let this degenerate into a conversation about OR mappers. I know that happens a lot on these forums.

I am using SQL 2000 with the Server Enterprise and the Query Analyzer programs. Almost everytime I create a new Stored Procedure, I forget to go into Server Enterprise and grant Execute permissions to my users.
Is there any way in a Stored Procedure to set the permissions when the Procedure is created?

Hi,
I am testing a method for users to only have the ability to execute only stored procedures that return data and not be able to execute procs that modify data. For testing purposes I have created a 'select' procedure and an 'insert' procedure. I created a user with db_datareader and execute permissions on the two procs and I was still able to execute the 'insert' proc as this user. I also attempted to deny insert permissions on the referenced table to no avail.
Short of establishing a role and granting execute permission to the appropriate procedures, is there a simpler way to do this?
Thank You
Michael

Is there any way to allow a user to use the xp_cmdshell extendedstored procedure without giving that user execute permissions toxp_cmdshell in SQL server 6.5? Let me clarify. Lets say I (as thedbo) create a stored procedure called sp_send_err:CREATE PROCEDURE sp_send_err @CompID varchar(20) ASdeclare @strCMD varchar(255)select @strCMD = "master.dbo.xp_cmdshell 'net send " + @CompID + """ERROR!""', no_output"execute (@strCMD)GONow lest say I give "user1" execute permissions on sp_send_err, but nopermissions on xp_cmdshell. When I run sp_send_error I get thefollowing error:"EXECUTE permission denied on object xp_cmdshell, database master,owner dbo".Why doesn't this work? What else can I do?

We are running SQL Server 2000 Developer Edition. I don't want tomake the developers the sysadmin or even the dbo in the userdatabases. Is there a way to give them access to only view thepermissions for the stored procedures in the user database withoutmaking them dbo?When I take them out of the db_owner role, when they open a storedprocedure they no longer see the permissions tab. I would like forthem to see the permissions tab and be able to view the permissionsbut not change the permissions.Is that doable?

I need to grant execute permissions on a stored procedure, can I do this from an asp/ASP.NET page?
The DB guys take 24 hours to run a script against the database!
Any help would be greatfully recieved.

In our development and test environments the developers need to create and execute stored procedures as dbo without having any other dbo permissions. If I place them in db_owner, they have too many permissions. Is there a way to address this situation?
I'm also curious how other companies address the subject of creating stored procedures in development and test environments. If I give developers create and execute permission in a database, all objects would be created as JohnDoe.storedprocedurename instead of dbo.storedprocedurename. Any help in this area is appreciated.

I am logging into a SQL instance to run the following query:
DECLARE @ReturnCode int EXECUTE @ReturnCode = [master].dbo.xp_create_subdir N'sharemasterFULL' IF @ReturnCode <> 0 RAISERROR('Error creating directory.', 16, 1)
The share in which the folder is to be created has my account added with full permissions to create files. However this command fails unless I add the SQL Service account user with rights to the folder also.
Is this expected behaviour, is this something specific to extended stored procedures?

I'm getting a strange error and I've run out of places to look to fix it. I'm running the following statement when connected as APP_USER in SQL Server Managment Studio (SSMS).
select * from cs.dbo.order
I get the following error.
Msg 229, Level 14, State 5, Line 1
SELECT permission denied on object 'ORDER', database 'CS', schema 'dbo'.
Even after running the following as SA, the result is the same
grant select on cs.dbo.order to APP_USER
Running the query as SA or as a user with datareader permissions works fine. The APP_USER can also select from another table in the same database and schema without error. The APP_USER has SELECT, INSERT, and UDPATE permissions on the table. A second user with only SELECT gets the same error.
I've tried removing and reapplying the permissions with no luck.
Searching for this problem all the examples I find are related to stored procedures (permissions not working the same on dynamic SQL). However, I'm not using a stored procedure. This is plain SQL in a query window in SSMS.
Any help on where else to look for the cause of this would be greatly appreciated.

I'm having a problem replicating stored procedure permssions accross two sql server 2005 servers, using transactional replication. When I replicate tables, it's easy enough to send the permissions over from the subscriber since there is an option under the articles properties for "Copy permissions." I can't seem to find any such option for SPs, UDFs or views. Am I missing something?
So the other idea I had was to create a script to grant the proper permissions, and run it using sp_addexecscript to my publication. Currently I have two one-way transactional publications. One publication for all my tables, and another for SPs, UDFs and views. I can run sp_addexecscript on the publication containing all my tables with out a problem, but when I run it against the publication containing my SPs, UDFs and views I get the following error:
Msg 21332, Level 16, State 1, Procedure sp_MSrepl_addscriptexec, Line 57
Failed to retrieve information about the publication : SP_UDF_Views_transactional. Check the name again.
I'm not sure why I'm getting this message. If anyone can help me out, I'd greatly appreciate it.

I am using SQL 2005, and I am wondering if there is a way to set up a role such that when a new stored procedure is created, the role will automatically be given "execute" permission on that stored procedure.
We have our own dedicated server, but I also administer a database on a shared server (on DiscountASP.net), and they have it set up that way -- when a new stored procedure is created, the user set up by DiscountASP automatically has EXECUTE permission on that procedure.
I keep trying to duplicate this on our dedicated server, but to no avail. I would like to make it so a specific role always has execute permission on every new stored procedure, without having to explicitly add permissions to the role using the properties of the stored procedure.
Is this possible? It seems like it should be, but I can't figure out how. (I'm primarily a programmer, not a DBA, so apologies if this is a dumb question.)

I have stored procedures. I have heard that it is a best practice to use stored procedures to encapsulate some SQL statements and then grant permissions to execute the stored procedure. But when I try this and use EXECUTE AS to test it out, the user in question gets errors about not having access to some of the underlying objects.
How does this best practice work? If I need to grant the user permissions to the underlying objects anyway, I am not sure why a stored procedure is considered best practice in this regard.

The developers in our shop have a need to explicitly grant view definition permissions to themselves on stored procedures they create in their development databases. They have dbo level permissions in these databases and although they can explicitly grant view definition permissions to other developers in the same database, they are unable to do so for themselves. When they attempt this, it appears that they are successful but when they check the stored procedure afterwards the permission is not there for themselves.
While this does not cause an issue in development, the intention is for these view definition permissions to be carried forward to the test and production databases where they only have datareader permissions.
When these stored procedures are scripted out by the dba to move to Test and Production the view definition permissions are not scripted out for the developer in question.
Is there a way that a developer with dbo rights in a database can explicitly grant themselves view definition permissions on a stored procedure they create as dbo?
