Configuration In SQLCLR Assembly
Aug 27, 2007
Hi,
I have an SQLCLR assembly which is required to connect to a remote WCF service. In order to do this in a host such as IIS you would need to store all your WCF configuration data (endpoints, types etc) in the Web.config or App.config (in a windows forms app). This begs the question: Where do you store configuration data for SQLCLR assemblies?
The System.Configuration assembly is available in the SQLCLR, but this assumes a Web or App config files exists? Does SQL have its own config file that you can keep your settings in which is called when the assembly is running from within the SQL process?
If this is not possible, should I rather be storing configuration data in the database itself?
This particular example relates to WCF configuration but is relevant for assemblies using Enterprise Library which is also config driven.
Any help would be appreciated.

Hi,
I have create few Mannaged SP which acces some external resources like closing and starting some windows process.. the assembly is assigend unsafe security level
all the processes are started from sqlserver.exe service and are allowed to interact with desktop
these SPs are called frequently
Problem... a very few times sql server is crashed..
does mannaged SP load app domain each time they are called?
what possible reason can be?
I am not exactly clear about the reson .. so I decided to post over here ..
Thanks,

In article http://support.microsoft.com/kb/913668 it says to generate a serialization assembly and pop this into the database along side the assembly with the serialized type. All well and good, but how doe the XmlSerializer know to look in the database for the assembly - does it use the name of the assembly + XmlSerializer?
It is certainly ambiguous in the aforementioned kb article. In one place it generates an assembly in the database called
CREATE ASSEMBLY [MyTest.XmlSerializers] from
'C:CLRTestMyTestMyTestinDebugMyTest.XmlSerializers.dll'
WITH permission_set = SAFE
and in another it uses
USE dbTest
GO
CREATE ASSEMBLY [MyTest] from 'C:CLRTestMyTest.dll'
GO
CREATE ASSEMBLY [MyTest.XmlSerializers.dll] from 'C:CLRTestMyTest.XmlSerializers.dll'
GO
I can't get either to work, and I've tried various combinations, this and the fact that the kb artice uses two different naming conventions suggests to me that there must be "something else" which links the assembly with the serialization assembly.
Any ideas?
Thanks,
Dan

I created a CLR function based on following VB code:
Imports Microsoft.SqlServer.Server
Public Partial Class SqlClrVB
<Microsoft.SqlServer.Server.SqlFunction()> _
Public Shared Function GetTotalPhysicalMemory() As Integer
GetTotalPhysicalMemory = My.Computer.Info.TotalPhysicalMemory
End Function
End Class
The VB code was complied into a DLL called totalmem.dll and call following TSQL to map it into a SQL function:
create assembly totalmem from '!WORKINGDIR! otalmem.dll'
WITH PERMISSION_SET=UNSAFE
go
create function fnGetTotalMem()
returns int
as external name totalmem.SqlClrVB.GetTotalPhysicalMemory
go
When I call this function, it returned following error:
select dbo.fnGetTotalMem()
Msg 6522, Level 16, State 2, Line 0
A .NET Framework error occurred during execution of user defined routine or aggregate 'fnGetTotalMem':
System.IO.FileNotFoundException: Could not load file or assembly 'System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.
System.IO.FileNotFoundException:
at Microsoft.VisualBasic.MyServices.Internal.ContextValue`1.get_Value()
at My.MyProject.ThreadSafeObjectProvider`1.get_GetInstance()
at SqlClrVB.GetTotalPhysicalMemory()
.
Anyone knows why I'm hitting this error? I didn't reference any System.Web interface why it needs to load System.Web assembly? The same code runs OK if I compile it as a separate VB application out side of SQL Server 2005.
Thanks much,
Zhiqiang

Hi all,
my problem is that: I do read informations (e.g. connectionString) from configuration file by one custom assembly.
My environment is RS2005, VS.NET 2005 Prof.Edition, WIN2003 Server SP1, .NET Framework 2.0.50727
The scenario is that:
A text box into my report require a function contained into MyCustom.dll. This code do read information from MyCustom.dll.config.
This file contains:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<connectionStrings>
<add name="IS2009cfg" connectionString="data source=servernameinstancename;initial catalog=dbname;user id=xx;password=yy;" />
</connectionStrings>
<appSettings>
<add key="DefaultHeaderLogo" value="This is a test" />
</appSettings>
</configuration>
Using
ConnectionStringSettings conn = ConfigurationManager.ConnectionStrings["IS2009cfg"];
the result is null.
Also using
string defaultHeaderLogo = ConfigurationManager.AppSettings["DefaultHeaderLogo"];
the result is null.
MyCustom.dll and MyCustom.dll.config are located into locations of Report Server and Report Designer, with this Build Events on succesfully build:
rem Copy custom assembly to ReportDesigner location...
copy "...mydeveloplocation...inDebugMyCustom.dll" "C:Program FilesMicrosoft Visual Studio 8Common7IDEPrivateAssembliesMyCustom.dll"
copy "...mydeveloplocation...inDebugMyCustom.dll.config" "C:Program FilesMicrosoft Visual Studio 8Common7IDEPrivateAssembliesMyCustom.dll.config"
rem Copy custom assembly to ReportServer location...
copy "...mydeveloplocation...inDebugMyCustom.dll" "C:Program FilesMicrosoft SQL ServerMSSQL.4Reporting ServicesReportServerinMyCustom.dll"
copy "...mydeveloplocation...inDebugMyCustom.dll.config" "C:Program FilesMicrosoft SQL ServerMSSQL.4Reporting ServicesReportServerinMyCustom.dll.config"
The question is simple: where I do locate configuration file for obtain value during report execution?
Many thank's in advance

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.

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.

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?

I'm having a problem executing a SQLCLR function: this function
calls a web services that processes a query to a data base and
returns a table to be used in a stored procedure. In a low
concurrency scenario (not to many clients connected), the function
returns correctly, however when the concurrency level is increased
we have a SQLCLR command execution problem (all the SQLCLR
processes hangs), making the server unavailable to all web services
processes.
At first we thought the problem could be the SQLCLR, since the web
services is 100% available, all the time. We monitored to come to
this conclusion. Do you know of some SQLCLR bug?
Could someone help me with this? I'm in a difficult situation with
my client, considering that we defended the MS SQLServer technology
and now it's not working properly.

I'll keep trying new threads here... sooner or later, I'm sure an expert Microsoft CLR employee will gladly lend a helping hand!
The pieces:
1. SQL 2005, MS Windows Server 2003, Standard Edition, SP 1
2. .NET 2005/C#
3. Instance of SQL 2005 running locally.
Trigger on local SQL2005 DB table INSERT calls 2 CLR Functions:
1. Retrieve data from SQL2005 DB table and populate local DBF through OLEDB
2. Call external 16-bit application (written in Clipper) that iterates through local DBF records (added from step 1 above) and populates DBF on domain resource.
Step 2 detail:
External 16-bit application is called by CreateProcessAsUser after impersonating token.
THIS IS SUCCESSFUL - IF: I populate SQL2005 DB table using TSQL insert statement. The trigger executes, Step 1 and Step 2 execute perfectly!
THIS IS UNSUCCESSFUL - IF: The SQL2005 DB table is populated by synchronizing SQL Mobile Server database from a SQL Mobile Edition 2005 PDA emulation. The trigger executes. Step 1 executes perfectly. Step 2 executes without exceptions. HOWEVER, the 16-bit application does not execute! Remember, no exceptions. In fact, the result variable returns true from function below:
result = ProcessUtility.CreateProcessAsUser(
hDupedToken,
null,
@"C:MobileDBMobile.exe",
ref sa, ref sa,
false, 0, IntPtr.Zero,
@"C:MobileDB", ref si, ref pi
);
Also, if I Right-click on the Step 2 function in the Server Explorer and click "Execute", it works perfectly. Domain DBF is updated successfully.
So, in short CLR "CreateProcessAsUser" is not doing it's job when the trigger is fired after SQL 2005 DB is populated via replication/sychronization. I would appreciate a response... Thx!

Hi,
My .NET SQL UDF needs do very complex computation on every call regardless on user input. I would be very happy if I could cache this computed data somewhere in SQL Server memory. And then I should not need to recompute this complex information on every UDF call. Is it possible to cache something inside SQL Server from CLR ?
Thanks.

I'm personally in favor of using the SQL CLR where appropriate, although I'm wondering what the negative consequences of enabling SQL CLR might be? Its disabled by default within SQL Server 2005 and most likely 2008, so what was the reason behind this ... beyond the fear of the DBA enabling something he might not himself fully understand.
Thanks,

By using impersonation I am able to push data to network path / old fashioned DBF's. Of course, I must use unsafe. I am unable, however to successfully run a "cmd.exe" process(), even if I populate the Username, Domain and password (with securestring). It authenticates correctly (checked by giving wrong password or bad username). But when it runs (even just a "cmd.exe"), I get an access is denied error...
StreamWriter sw = File.CreateText("C:\Error.txt");
WindowsIdentity clientId = null;
WindowsImpersonationContext impersonatedUser = null;
clientId = SqlContext.WindowsIdentity;
impersonatedUser = clientId.Impersonate();
System.Security.SecureString password = new System.Security.SecureString();
foreach (char c in "secret")
password.AppendChar(c);
Process p = new Process();
ProcessStartInfo si = new ProcessStartInfo("cmd.exe");
si.UserName = "MyName";
si.Password = password;
si.Domain = "MySecretDomain";
si.UseShellExecute = false;
try
{
p.StartInfo = si;
p.Start();
}
catch (Exception ex)
{
//handle the exception here (This exception handler will not handle the exception, but I get a
//Window popup (While executing my CLR!!!)
}
finally
{
sw.Close();
}
The message popup says: The application failed to initialize poperly (0xc0000142). Click on OK to terminate the application. I'm kind of at a loss...
I'm using a Windows 2003 server box with the latest SQL Server 2005, .NET 2.0/2005. Let me know if you need anything else.
Oh, just FYI - I am moving replicated data from SQL2005 server to a legacy app using DBF (FoxPro driver). I really need an external DOS app to process some data for the DOS application (Clipper).

I am searching for a way of using SQLCLR to do Bulk Insert/Copy within SQL Server 2005.
I am not permit to use SQL command BULK INSERT with any of text based file csv, or xml etc.
I did tried to use SqlBulkCopy within SQLCLR but failed, the context connection was not allowed, I did also use normal connection string with sa & pwd but no luck.
I understand that I can move bulk insert to a service such as windows, web or WCF but it is not on the card at present.
Is there a way of doing this within CLR, size of bulk is fair about 2000+ rows.
If you have solution, sample or link would be appriciated.
Cheers

Problem:
I have an sp which start an external process, It is working at my local machine but does not work at remote server.
FACTS:
Local machine has SQLExpress (SQL version) while remote machine has SQL Enterprise ..
SQL service is running under the System Account at both machines..
I have enabled the Sql server Service to interact with desptop, so that it can start a process in GUI mode.
I thin there is something in connectionstring which does not allow the application to connect to server with appropriate rights.
How I can chage this setting .. is it possible to write this info manually..
Please, comments
Thanks

Just wondering which scenarios is suitable to use SQLCLR. Any kind of data access is not recommended I guess. Only things that cannot be easily done in TSQL should be done in SQLCLR but why? Can't those things be done in app layer itself? Scenarios recommended for SQL CLR:
- External data access like filesystem, registry etc
- Complex calculation
- Recursion without data access (this can be implemented with CTE for data access)
If data access with SQL CLR is not recommended why should CLR should be even used and logic reside in database layer.. it makes no sense to me. Any thoughts??

Is there a limit to the number of connections that can be made to the SQLCLR? If so, what is that limit and is it adjustable?
Thanks!

I have just begun to delve into the SQLCLR objects in SQL Server 2005. I have created a simple VB function as a SQLFunction. Here's the code:
Imports System
Imports Microsoft.SqlServer.Server
Partial Public Class UserDefinedFunctions
<Microsoft.SqlServer.Server.SqlFunction()> _
Public Shared Function FileDate(ByVal FilePath As String) As Date
Return FileDateTime(FilePath)
End Function
End Class
The function is run with this T-SQL:
declare @FileDate datetime
select @FileDate = dbo.FileDate('C:setup.bat)
select @FileDate
This works fine, but I had to set the Permission Level of the Visual Studio project to "Unsafe" rather than "External" in order to avoid the following error message:
A .NET Framework error occurred during execution of user defined routine or aggregate 'FileDate':
System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.SecurityPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
Is there any way to avoid having to set the permission level to "Unsafe"? If not, what does "unsafe" mean in terms of overall system security? Is it acceptable to use on an internal LAN?
Thanks,
Ron

Hi
I had DTS the Northwind sample database from SqlServer 2000 to 2005. It's went ok and no errors. Then, I created a SP named upGetCustomer, bascially it queries the Customers table and list some of it's fields and order by CustomerId,CustomerName, Country decrementally. SP is so simple and has no errors.
Then, I created a SqlServer project in VS2005 using C#. Add store procedure class as below,
using System;
using System.Data;
using System.Data.SqlClient;
using System.Data.SqlTypes;
using Microsoft.SqlServer.Server;
public partial class StoredProcedures
{
[Microsoft.SqlServer.Server.SqlProcedure]
public static void Customers(string customerid)
{
using (SqlConnection sqlConn =
new SqlConnection("context connection=true"))
{
sqlConn.Open();
SqlPipe sqlPipe = SqlContext.Pipe;
SqlParameter param = new SqlParameter("@custId", SqlDbType.VarChar, 5);
param.Value = customerid;
SqlCommand sqlCmd = new SqlCommand();
sqlCmd.CommandType = CommandType.StoredProcedure;
sqlCmd.CommandText = "upGetCustomer";
sqlCmd.Parameters.Add(param);
SqlDataReader rdr = sqlCmd.ExecuteReader();
SqlContext.Pipe.Send(rdr);
}
}
I had taken method of created SQLCLR from source in Microsoft website, but coding is mine, and hopes it is correct. I used SqlConnection string as 'context connection=true' which I still not quite sure what does it means, hopes it mean current connection I am using on my Windows authentication.
The project did compiled & deployed OK on the VS2005 side.
The problem is that when I tried to locate the assembly on the Sql Server 2005, but can't find it anywhere on Sql Server.
I did try complied and deloyed again, it keeps saying there is an error in deployment as customers assembly is already exist on the database. I then, tried to remove this assembly on the database using SQL script, drop assembly customers in the Northwind database but got error saying it does not exist. So where is it???
Please help...
Thank you

I keep getting different answers from different people on regarding if you can or cannot kill the hosting sql server process with an unsafe assembly. Can you do this? If so could you please attach a sample demonstrating this?
Thanks,
Derek

Throughout the course of this book and even before it I have come across conflicting information regarding how SQLCLR attempts to resolve system/CLR assembly references. For example, prior to my latest read thourgh April BOL 2005, I thought SQLCLR attempted to resolve these references implicity for you via the local machine's GAC. Yet here is what I found while trying to help another person in this forum yesterday in BOL...
Assembly Validation
SQL Server performs checks on the assembly binaries uploaded by the CREATE ASSEMBLY statement to guarantee the following:
The assembly binary is well formed with valid metadata and code segments, and the code segments have valid Microsoft Intermediate language (MSIL) instructions.
The set of system assemblies it references is one of the following supported assemblies in SQL Server: Microsoft.Visualbasic.dll, Mscorlib.dll, System.Data.dll, System.dll, System.Xml.dll, Microsoft.Visualc.dll, Custommarshallers.dll, System.Security.dll, System.Web.Services.dll, and System.Data.SqlXml.dll. Other system assemblies can be referenced, but they must be explicitly registered in the database.
For assemblies created by using SAFE or EXTERNAL ACCESS permission sets:
The assembly code should be type-safe. Type safety is established by running the common language runtime verifier against the assembly.
The assembly should not contain any static data members in its classes unless they are marked as read-only.
The classes in the assembly cannot contain finalizer methods.
The classes or methods of the assembly should be annotated only with allowed code attributes. For more information, see Custom Attributes for CLR Routines.
Besides the previous checks that are performed when CREATE ASSEMBLY executes, there are additional checks that are performed at execution time of the code in the assembly:
Calling certain Microsoft .NET Framework APIs that require a specific Code Access Permission may fail if the permission set of the assembly does not include that permission.
For SAFE and EXTERNAL_ACCESS assemblies, any attempt to call .NET Framework APIs that are annotated with certain HostProtectionAttributes will fail.
COULD SOMEONE PLEASE GIVE ME THE DEFENITE ANSWER ON HOW THIS WORKS!

Hi,
I've got a requirement for a procedure to write a text file and want to do it without using command line utilities.
I wrote a sqlclr which queries a db and writes the file that I need. After setting the external_access and database to trustworthy, It only works on my own machine, not on network shares.
Some threads I've found have been related to the "1 network hop" of Windows credentials, which most of us are probably familiar with.
It doesn't make sense to me that this is the problem, since I'm on my workstation, connecting to a local db instance and hopping one time to the shared server. Anyone know what the cause might be?

hi, Derek Comingore
My self Jitendra Nayi....
I am trying to generate a SQL CLR stored procedure and i have done it too. Now the next step is to convert that *.dll file in to assembly. I am getting erro that. My server Database is on the LAN, not on my PC.
Here is the code which i have tried to register an assembly...
/*
CREATE ASSEMBLY MyAssembly FROM 'C:Documents and SettingsAdministrator.ORC80My DocumentsVisual Studio 2005ProjectsMyDB1MyDB1inDebugMyDB1.dll'
WITH PERMISSION_SET=SAFE
GO
*/
and here is the error that i am getting...
/*
Msg 6585, Level 16, State 1, Line 1
Could not impersonate the client during assembly file operation.
*/
Please help me .I am stuck at here.

Hi all,
The problem is: when you're trying to call in method MyMethod anonymous method that doesn't use local variables, deployment of the assembly will fail referring that MyMethod tries to store smth. in the static variable. Indeed, looking at the compiled CLR code, you can see that anonymous delegate is cached in the private static delegate and the call looks like:
If(ClassName.privateStaticDelegate == null)
ClassName.privateStaticDelegate = new MyDelegate(HiddenMethodName);
CallAnonymousMethod(ClassName.privateStaticDelegate);
Is there any workaround to fix this problem.
P.S. I googled about this problem and found only one article on it:
