.NET Framework :: Grant DnsPermission To Assembly?
May 3, 2015
Ported RabbitMQ over to .NET 3.51 over without the SYstem.ServiceModel dependencies.My SQL CLR Proc invokes rabbit to publish a message but then gets a DNS error because of limited permissions:
RabbitMQ.Client.Exceptions.BrokerUnreachableException: None of the specified endpoints were reachable ---> System.Security.SecurityException: Request for the permission of type 'System.Net.DnsPermission, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'
failed.
[Code] .....
What's strange is that I added the RabbitMQ assembly with the unsafe option so it seems like this should just work with no CAS headaches:
CREATE ASSEMBLY [RabbitMQ.Client]
      FROM 'c:SqlClrRabbitMQ.Client.dll' WITH PERMISSION_SET = UNSAFE
GO
How do I get by the DNSPermission check in SQL CLR?

I have build a vb.net class that uses the AxMetadataServiceClient (MS Dynamics Axapta model store) this class works like expected in .net app.When I try to create this assembly in sql it fails with this error
Msg 10300, Level 16, State 2, Line 6
Assembly 'System.EnterpriseServices' references assembly 'System.EnterpriseServices, version=4.0.0.0, culture=neutral, publickeytoken= b03f5f7f11 d50a3 a.', which is not present in the current database.
SQL Server attempted to locate and automatically load the referenced assembly from the same location where referring assembly came from, but that operation has failed (reason: version, culture or public key mismatch). Please load the referenced assembly into the current database and retry your request.can't create the assembly since it references it self and can't find it self ?

I have a database with deployed CLR assembly on SQL 2008. I recently took a backup for the database and restored it on SQL 2012 server. Everything worked fine except very strange working of CLR assemblies functions.The result of the function is very odd. It manipulates the numeric string and return the result. It is returning very strange result on SQL 2012 as compared to SQL 2008.Example SQL 2008 ManipulateString('1234') returns 2345 On SQL 2012 the same call returns 1155.I am also trying to deploy the same assembly to SQL 2012 server database. I have successfully register the assembly, but the database do not list the exposed methods.

CLR's not registered as SAFE are disallowed on our Network. It appears that the key associated with the assembly (ISSERVER) may be able to link to the Service Master Key. If the service master key is created with a (CA) Certificate Authority, is it possible to create the SSISDB that accompanies the Integration Services Catalog as a SAFE assembly?
[adding] BY CA meaning:
ALTER SYMMETRIC KEY [mykey] ADD ENCRYPTION BY CERTIFICATE [myservercertname]Â

Dear all,
Basically I want to set chain up the rights so that the anonymous web user IUSR_ .. can execute the new .NET subs, functions etc in the assembly, just as the anonymous web user can execute Stored Procedures when granted. In this way, it should be possible to call the .NET assembly just as classic stored procedures from ASP/ASP.NET.
I have written a .NET function which I can successfully execute if I log on to the database as an administrator by sending this T-SQL query; it returns the result of a given string:
select dbo.CLRHTMLString('abc')
The scenario is now to try to grant access to this assembly for a different role (webuser), which the classic IUSR_MYSERVERNAME is a login of, so that I can call the .NET Assembly when I am authenticated as the anonymous web user (e.g. via ASP, etc.).
To test access, I created a login (webusertest) for a user (webusertest) in the same role (webuser) on the database. But when I use this login, which supposedly has the same rights as the IUSR_, execution right is denied:
EXECUTE permission denied on object 'CLRHTMLString', database 'adt_db', schema 'dbo'.
Note: The 'webuser' database role has Execute permission on the Assembly.
I have also tested this from my actual web page, with the following results:
(1) IUSR_MYSERVER member of db_owner role: Web page has right to call assembly.
(2) IUSR_MYSERVER not member of db_owner role: Web page does not have right to call assembly.
Further test results:
(3) Function can be called when making the user "webusertest" member of the "db_owner" role, which is too much rights to grant for the anonymous web user.
(4) When adding the user 'webusertest' to get 'Execute' permissions on the assembly, it does not get added. After clicking OK, there is no warning message, but when opening the Assembly Properties -> Permission dialog box the same time, the 'webusertest' user does not appear in the list.
Thankful for any advice on this matter.

I work with February CTP of SqlServer 2008.
I have an Assembly with several UDTs inside. Version of assembly is 1.0.*
I use CREATE ASSEMBLY statement to register this assembly, and it runs without any errors. Then I rebuild CLR solution without doing any changes in source code. In that case the only difference between new and old assemblies is version (difference in fourth part of version).
Then I try to update assembly in SqlServer. I use
ALTER ASSEMBLY <name>
FROM <path>
WITH PERMISSION_SET = UNSAFE, UNCHECKED DATA
statement for this. Statement runs with error:
Msg 6509An error occurred while gathering metadata from assembly €˜<Assembly name>€™ with HRESULT 0x1.
I found the list of condition for ALTER ASSEMBLY in MSDN:
ALTER ASSEMBLY statement cannot be used to change the following:
· The signatures of CLR functions, aggregate functions, stored procedures, and triggers in an instance of SQL Server that reference the assembly. ALTER ASSEMBLY fails when SQL Server cannot rebind .NET Framework database objects in SQL Server with the new version of the assembly.
· The signatures of methods in the assembly that are called from other assemblies.
· The list of assemblies that depend on the assembly, as referenced in the DependentList property of the assembly.
· The indexability of a method, unless there are no indexes or persisted computed columns depending on that method, either directly or indirectly.
· The FillRow method name attribute for CLR table-valued functions.
· The Accumulate and Terminate method signature for user-defined aggregates.
· System assemblies.
· Assembly ownership. Use ALTER AUTHORIZATION (Transact-SQL) instead.
Additionally, for assemblies that implement user-defined types, ALTER ASSEMBLY can be used for making only the following changes:
· Modifying public methods of the user-defined type class, as long as signatures or attributes are not changed.
· Adding new public methods.
· Modifying private methods in any way.
But I haven€™t done any changes in source code, so new version of assembly satisfies all this conditions.
What could be the reason for such behavior?
P.S. I€™ve got the same error, if I add or change any method in assembly before rebuilding.

GRANT SELECT ON [dbo].[TblAreaCatmap] TO [admin] prevent grant from being automaticly add to each column?
Is there a way when you issue a grant select to a table or a view to not also grant select for each column.
The problem is when you use the grant command it automaticly adds the grant command to each column. I want to grant the permission at the table level so when the table is scripted it only has a single grant command instead of a grant for the table and a grant for each column which is not needed.
The sql managemnt studion interface will allow you to do this but onlt by using the interface. If you issue the above command from a query window it also creates A GRANT FOR EVERY COLUMN. How can I stop this behavior.

I am writing a stored procedure which updates a table, but when I run the stored procedure using a login that I have granted execute privileges on, then I get a message that I cannot run an update on the table. This would happen in dynamic sql... while my SQL has parameter references, I don't think it is considered dynamic SQL?
sproc:
CREATE PROCEDURE [schemaname].[SetUserCulture]
@UserID int
, @Culture nvarchar(10)
AS
UPDATE dbo.SecUser
SET Culture = @Culture
WHERE UserID = @UserID
execute SQL:
EXEC schemaname.SetUserCulture @UserID = 9, @Culture = N'x'
error:
The UPDATE permission was denied on the object 'SecUser', database 'DatabaseName', schema 'schemaname'.

In SQL Server 2005 SP2 I want to grant the ability to create views to a user but in order to do this it requires that the users has the ability to grant alter on a schema.

I am trying to get a function I created in VB 5 for Access and Excel to work in SQL 2005. I was able to update the old VB code to work in VB 2005. I compiled and made a .dll, and I was able to register the new Assembly in SQL Server. When I try to create the Function, I get an error:
CREATE FUNCTION dbo.Temperature(@FluidName char, @InpCode Char, @Units Char, @Prop1 varchar, @Prop2 varChar)
RETURNS VarChar
AS EXTERNAL NAME FluidProps.[FluidProps.FluidProperties.Fluids].Temperature
Error returned:
Msg 6573, Level 16, State 1, Procedure Temperature, Line 21
Method, property or field 'Temperature' of class 'FluidProps.FluidProperties.Fluids' in assembly 'FluidProps' is not static.
Here is the code (part of it) in the VB class:
Header:
Imports Microsoft.SqlServer.Server
Imports System.Data.SqlClient
Imports System.Runtime.InteropServices
Imports System.Security
Imports System.Security.Permissions
Namespace FluidProperties
'Option Strict Off
'Option Explicit On
Public Partial Class Fluids
Function:
Function Temperature(ByRef FluidName As Object, ByRef InpCode As Object, ByRef Units As Object, ByRef Prop1 As Object, Optional ByRef Prop2 As Object = Nothing) As Object
Call CalcProp(FluidName, InpCode, Units, Prop1, Prop2)
Temperature = ConvertUnits("-T", Units, T, 0)
End Function
If I change the Function Temperature to Static, I get an error that functions cannot be Static. Its been a long time since I created the code and am having a hard time in my older age of getting the cobwebs out to make it work.
I have no problem getting the function to work if I call it from a VB form....so what do I need to do to get it to work on data in my SQL server?
Thanks

I previously had an ASP.NET 1.1 site running on my IIS 6.0 server (not the default website) with Reporting Services running in a subdirectory of that website. I recently upgraded to ASP.NET 2.0 for my website and was greeted with an error when trying to view a report. The error was very non-descript, but when I checked the server logs, it recorded the details as "It is not possible to run two different versions of ASP.NET in the same IIS process. Please use the IIS Administration Tool to reconfigure your server to run the application in a separate process."
First of all, I could not figure out where and how to do this. Secondly, I decided to try to also change the Reporting Services folders to run ASP.NET 2.0 and when I did, I was greeted with the following message when attempting to view a report:
"Failed to load expression host assembly. Details: StrongName cannot have an empty string for the assembly name."
Please help.

Hi
I am a bit paranoid about what I just did to my SQL Server 2005 with this CLR experiment.
I created a Class Lib in C# called inLineLib that has a class Queue which represents an object with an ID field.
in another separate namespace called inLineCLRsql, I created a class called test which will hold the function to be accessed from DB, I referenced and created an instances of the Queue class, and retrieve it's ID in a function called PrintMessage.
namespace inlineCLRsql{
public static class test{
public static void PrintMessage(){
inLineLib.Queue q = new inLineLib.Queue();
int i = q.queueId ;
Microsoft.SqlServer.Server.SqlContext.Pipe.Send(i.ToString());
}
}
}
to access this from the db, I attempted to create an assembley referencing inLineCLRsql.dll. This didn't work as it complained about inLineLib assembly not existing in the db. I then attempted to create an assembley for inLineLib but it barfed saying System.Management assembly not created.
so what I did is (and this is where I need to know if I just ruined sql server or not):
1- ALTER DATABASE myDB SET TRUSTWORTHY ON;.
2- CREATE ASSEMBLY SystemManagement
FROM 'C:WINDOWSMicrosoft.NETFrameworkv2.0.50727System.Management.dll'
WITH PERMISSION_SET = UNSAFE
3- CREATE ASSEMBLY inLineLibMaster
FROM 'D:inLineServerinLineLibinDebuginLineLib.dll'
WITH PERMISSION_SET = unsafe
4- and finally
CREATE ASSEMBLY inLineLib
FROM 'D:inLineServerCLRSQLinlineCLRsqlinDebuginlineCLRsql.dll'
WITH PERMISSION_SET = SAFE
Everything works after those steps (which took some trial and error). I can create a sproc like:
CREATE PROC sp_test AS
EXTERNAL NAME inLineLib.[inlineCLRsql.test].PrintMessage
and it returns the Queue ID
Is there anything unadvisable about the steps above?
Thanks for your help

We have written a test CRL stored procedure to test replacing one of our complex stored procedures but can€™t get it deployed to our SQL server that hosts a mirrored configuration of our production database (very locked down). It works fine on our development instances (not very locked down). It only references the default assemblies that were added when we created the project. All it does is use Context Connection=true to get data, loops though some records and returns the data using SQLContext. CLR is enabled on SQL server, the assembly is strongly signed, and we tried deploy using the binary string with the SAFE setting.
CREATE ASSEMBLY for assembly 'SQLCLRTest2' failed because assembly 'SQLCLRTest2' failed verification. Check if the referenced assemblies are up-to-date and trusted (for external_access or unsafe) to execute in the database. CLR Verifier error messages if any will follow this message
[ : SQLCLRTest2.StoredProcedures::GetLift][mdToken=0x600001e] Type load failed.
[token 0x02000008] Type load failed.

I am trying to deploy a Database Project with Visual Studio 2005 and SQL Server 2005 Standard.
I import €œSystem.IO€? and have therefore set the permission levels to EXTERNAL_ACCESS.
I am receiving the same error message that many folks have received.
CREATE ASSEMBLY for assembly 'Images' failed because assembly 'Images' is not authorized for PERMISSION_SET = EXTERNAL_ACCESS.
The assembly is authorized when either of the following is true: the database owner (DBO) has EXTERNAL ACCESS ASSEMBLY permission and the database has the TRUSTWORTHY database property on; or the assembly is signed with a certificate or an asymmetric key that has a corresponding login with EXTERNAL ACCESS ASSEMBLY permission. If you have restored or attached this database, make sure the database owner is mapped to the correct login on this server. If not, use sp_changedbowner to fix the problem. Images.
My CLR access is €œon€?
I have tried
1) From master run: GRANT EXTERNAL ACCESS ASSEMBLY to [BuiltinAdministrators].
2) From master run: GRANT EXTERNAL ACCESS ASSEMBLY to €œMy Windows Authentication ID€?.
3) Run ALTER DATABASE MYDATABASE SET TRUSTWORTHY ON
4) In Visual Studio .NET 2005 Set the permission levels to €˜external€™
5) Tried BuiltinAdministrators and my SQL Server Windows Authenticated Login ID for the ASSEMBLY OWNER.
I can compile BUT NOT DEPLOY
Any help would be greatly appreciated.
Regards Steve

I was trying to understand how VS.NET2005 was deploying .NET CLR assemblies to SQL2005 so I ran a trace and found some interesting results.
VS.NET creates some SQL that looks pretty interesting:
CREATE ASSEMBLY [AssemblyNameHere]
FROM 0x4D5A90000300000004000000FFFF000......<continue binary data>
WITH PERMISSION_SET = EXTERNAL_ACCESS
Boy howdy!
I have tried to reproduce this and create my own deployment application but I cant figure out how they create this binary stream. The info in BOL is not much help and I have not found any samples anywhere on how to create this stream in c#.
Anyone out there been able to get this to work?

Hi there.
I have an assembly, call it A1, that I've deployed to a SQL Server 2005 database. I can use the managed stored procedures from A1 in SQL Server no problem.
In A1 there is a bit of code which uses the Assembly.Load() method, so load another assembly and use instances of class found in that external assembly. However, when I run the managed stored proc in A1 that uses Assembly.Load() I get the error:
Could not load file or assembly 'A1, Version=1.0.0.0, Culture=neutral,PublicKeyToken='????' or one of its dependencies. The system cannot find the file specified.
(note: for security I've changed some of the above line).
So I changed the Assembly.Load() to use
System.Data,Version=2.0.0.0,Culture=neutral,PublicKeyToken=b77a5c561934e089
I re-built the project, re-deployed it and ran the code in SQL Server - it worked. I could create an instance of a System.Data.DataSet for example. So why can't I load my own custom assembly? My assembly does have a strong name and it's installed in the GAC. I wrote a console app to try and Assembly.Load() my custom assembly and that worked fine (it was also running on the same server as the SQL Server).
So it's defiantely the SQL Server that can't 'see' my customer assembly. What do I need to do this assembly so that SQL Server will allow me to Assembly.Load it, just as it can with System.Data?
Thanks
Jas.

Will this affect SQL Server at all? If so, how can we accomplish the reinstall safely?

I'm having a problem regeistering a downloaded program. All firewalls were disabled before downloading. When the CD Key is input the following message occurs:
"An error has occurred attempting to register your copy of Encompass, The underlying connection was closed: Unable to connect to remote server."
The desktop engine (MDSE) was checked and running. The CD Key is correct.
I was steered to this website because someone felt that this may be a .network connectivity issue to Encompass registration. After weeks back and forth with the software techs at Encompass they have given up.
Can someone please help me. I'm willing to try anything. Keep in mind I am not a "computer tech" person but I can read and follow directions. I'm desperate!!!

I have some user defined CLR function. One of my STPs uses this function. Sometime next exception is thrown by SQL server:
DB Error: A .NET Framework error occurred during execution of user defined routine or aggregate 'UnzipProcedure':
System.TypeInitializationException: The type initializer for 'System.Data.SqlClient.SqlConnection' threw an exception. ---> System.Threading.ThreadAbortException: Exception of type 'System.Threading.ThreadAbortException' was thrown.
System.Threading.ThreadAbortException:
System.TypeInitializationException:
at System.Data.SqlClient.SqlConnection..ctor(String connectionString)
at UserDefinedFunctions.UnzipProcedure()
Where UnzipProcedure is user defined function.
If this exception happen, all other calls to STP that uses UnzipProcedure would return exception. Restart of a SQL server is helpful.
Does anyone meat the exception in similar circumstances? Is any way to recreate such exception? My quess is that there is some lock on resource that UnzipProcedure use. How can I figured out what resource is busy? Any other suggestions.
Thank You in advance.

you can, with a dataset do something like myDataSet.WriteXml(m_XmlFile, XmlWriteMode.IgnoreSchema) and get XML for a record....
is it possible to do something like that with SQLserverCeresultset?
i know i could probably loop thru the columns and create the xml manually... but using somethinglike writexml will give better performance?
right now im not using anything from the XML class... from my previous exp with using XML classes on the Compact framework gives slow performance...

I was initially interested in building my small retail app on Framework 3.5, until just now when I saw the download size. I won't make a single sale with that as a prerequisite.
I would, however, like to use VS2008 for this. If I target Framework 2.0, will I still be able to use SQLCE v3.5? The new SET IDENTITY INSERT functionality is an absolute requirement. (Note: I haven't installed VS2008 yet--I'm still investigating options.)
