I created a SQL Server Project in VS 2005, and tried to add a reference to SQLDMO Object dll. But the reference --> add reference, does not allow it. It does not work, even if I set the Assembly Permission Level to UNAFE/EXTERNAL ACCESS.
Reason I'm trying to do this:
We have a SQL 2000 stored procedure that uses SQLDMO using sp_OACreate to BCP files to database. We are converting to 2005 and because of SOX restrictions, I'm trying to replace the sp_OACreate part with external stored procedure written in C#.
According to BOL, I thought atleast UNSAFE should support this, but it seems not.
I'm trying to create an "unsafe assembly": USE master GO
CREATE ASYMMETRIC KEY StoredProcedures_dll_Key FROM EXECUTABLE FILE = 'C:Documents and SettingsAll UsersDocumentshunterStoredProcedures.dll';
CREATE LOGIN StoredProcedures_dll_Login FROM ASYMMETRIC KEY StoredProcedures_dll_Key;
GRANT EXTERNAL ACCESS ASSEMBLY TO StoredProcedures_dll_Login; GO
USE gfx_sa GO
CREATE ASSEMBLY hunter_storedProcedures FROM 'C:Documents and SettingsAll UsersDocumentshunterStoredProcedures.dll' WITH PERMISSION_SET = UNSAFE; GO
CREATE PROCEDURE [dbo].[hunter_storedProcedure1] ( @symbol_id as int ) AS EXTERNAL NAME hunter_storedProcedures.StoredProcedures.StoredProcedure1 GO
But on 'CREATE ASSEMBLY" clause I'm getting error: Msg 0, Level 11, State 0, Line 0 A severe error occurred on the current command. The results, if any, should be discarded. Msg 0, Level 20, State 0, Line 0 A severe error occurred on the current command. The results, if any, should be discarded.
I think I have some kind of permission problem. But first things first:
I have code which I would like to run in SQL Server (CLR Integration). First thing is that my code uses third-party-dll. I have to deploy my code as unsafe because of
"
CREATE ASSEMBLY failed because method "add_FunctionAdd" on type "USP.Express.Pro.FunctionsCollection" in safe assembly "USP.Express.Pro.2.0" has a synchronized attribute. Explicit synchronization is not allowed in safe assemblies. "
Of course I can not create "asymmetric key" for third-party-dll (Or can I?).
So, I tried to use trustworthy DB. But I get all the time error Msg 10327: "Assembly is not authorised for PERMISSION_SET=UNSAFE"
I am using Windows Login to log on Sql Server. Login is granted "Unsafe assembly" and DB has trustworthy setting "on".
Login has server roles "sysadmin" and "securityadmin". Login is mapped with DB User who has same name ( DOMAINUserName ) and has default schema "dbo". Login has DB memberships "db_owner" and "db_securityadmin". DB user owns schemas "db_owner" and "db_securityadmin".
Am I missing something?
Interesting thing is that I can do deployment (as unsafe assembly) in master-database. But not in the other databases.
Questions are: - Is there other way to authorise third-party-dll than using trustworthy? - Why deployment can be done in master-database?
And finally: - Why deployment can not be done in other database?
Can someone verify that an assembly containing an interface with an event definition, such as...
public interface A { event EventHandler Foo; }
... can never be loaded under SAFE or EXTERNAL_ACCESS ?
It appears that the compiler-generated add_xxx and remove_xxx have the MethodImpl(MethodImplOptions.Synchronized) attribute defined by default, and "Explicit synchronization is not allowed". The same limitation also applies to classes by default, although technically one is able to define the implementation directly (clearly not ideal).
For example, the table below, has a foreign key (ManagerId) that points to EmployeeId (primary key) of the same table. -------Employees table-------- EmployeeID . . . . . . . . . . int Name . . . . . . . . . . . nvarchar(50) ManagerID . . . . . . . . . . . int
If someone gave you an ID of a manager, and asked you to get him all employee names who directly or indirectly report to this manager. How can that be achieved?
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:
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
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?
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."
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.
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?
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 tried to create a sp on one of the databases on my lap top and got this: Pls help i need it bad
Msg 10314, Level 16, State 11, Procedure ap_Hello, Line 5
An error occurred in the Microsoft .NET Framework while trying to load assembly id 65695. The server may be running out of resources, or the assembly may not be trusted with PERMISSION_SET = EXTERNAL_ACCESS or UNSAFE. Run the query again, or check documentation to see how to solve the assembly trust issues. For more information about this error:
System.IO.FileLoadException: Could not load file or assembly 'vbtriggers, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. An error relating to security occurred. (Exception from HRESULT: 0x8013150A)
To set up a managed sproc to act as a WSE 3.0 web service client I had to register the following .Net DLLs as UNSAFE assemblies: System.Configuration.Install.dll System.Web.dll Microsoft.Web.Services3.dll
In order to register UNSAFE assemblies I had to set the database's TRUSTWORTHY property to 'true'.
Can anyone tell me what are the implications of doing this?
I develop a database that notifies clients when data changes by sending an UDP broadcast message using an extended stored procedure. Now I want to use a CLR stored procedure to send the UDP broadcast instead:
using System;
using System.Data.SqlTypes;
using Microsoft.SqlServer.Server;
using System.Net.Sockets;
public partial class UserDefinedFunctions
{
[SqlProcedure]
public static void UdpSend(SqlString address, SqlInt32 port, SqlString message)
{
System.Net.Sockets.UdpClient client = new System.Net.Sockets.UdpClient();
I have found that to be allowed to send to 255.255.255.255 I must give the assembly permission set 'Unsafe'. If I change to 'External access' I get:
Msg 6522, Level 16, State 1, Procedure UdpSend, Line 0
A .NET Framework error occurred during execution of user defined routine or aggregate 'UdpSend':
System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.SecurityPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
System.Security.SecurityException:

at System.Security.CodeAccessPermission.Demand()

at System.Net.Sockets.UdpClient.Send(Byte[] dgram, Int32 bytes, String hostname, Int32 port)
at UserDefinedFunctions.UdpSend(SqlString address, SqlInt32 port, SqlString message)
I cannot use permission set 'Unsafe' in production environment, so what I want is to customize the effective permissions with higher resoloution than the three pre-defined permission sets 'Safe', 'External access' and 'Unsafe'. Except from what is allowed by 'Safe' I only want the permissions necessary to send an UDP broadcast.
I have to make a gateway to access third-party closed-source native-code COM objects. As an interface, SQL Server stored procedures are absolutely perfect for my needs. I decided to use SQL Server 2005 CLR rather than using deprecated extended stored procedures or accessing COM objects directly through SQL Server. (This decision is aided by the fact that the third party has plans to make a .NET version of their COM objects "really soon now" (i.e.: not soon enough). Backporting their new interface to my abstraction layer will be very simple.)
I'm having problems using these COM objects from my SQL Server 2005 CLR stored procedure. When I try to run my stored procedure, I get the error below. It appears that SQL Server/CLR refuses to perform the disk access necessary to load the COM object from disk so that it can instantiate it. (My message continues after the error.)
Msg 6522, Level 16, State 1, Procedure MyStoredProcedure, Line 0 A .NET Framework error occurred during execution of user defined routine or aggregate 'MyStoredProcedure': System.IO.FileLoadException: LoadFrom(), LoadFile(), Load(byte[]) and LoadModule() have been disabled by the host. System.IO.FileLoadException: at System.Reflection.Assembly.nLoad(AssemblyName fileName, String codeBase, Evidence assemblySecurity, Assembly locationHint, StackCrawlMark& stackMark, Boolean throwOnFileNotFound, Boolean forIntrospection) at System.Reflection.Assembly.InternalLoad(AssemblyName assemblyRef, Evidence assemblySecurity, StackCrawlMark& stackMark, Boolean forIntrospection) at System.Reflection.Assembly.InternalLoadFrom(String assemblyFile, Evidence securityEvidence, Byte[] hashValue, AssemblyHashAlgorithm hashAlgorithm, Boolean forIntrospection, StackCrawlMark& stackMark) at System.Reflection.Assembly.LoadFrom(String assemblyFile, Evidence securityEvidence, Byte[] hashValue, AssemblyHashAlgorithm hashAlgorithm) at System.Activator.CreateComInstanceFrom(String assemblyName, String typeName, Byte[] hashValue, AssemblyHashAlgorithm hashAlgorithm) at System.Activator.CreateComInstanceFrom(String assemblyName, String typeName) at UserDefinedFunctions.MyStoredProcedure() .
I'll outline the steps I performed so far to get the assembly working: Ensured I was running at SQL Server 2005 compatibility level. (90) - Installed and configured the third-party COM objects on my devel box and my DB box. They registered themselves properly. - Enabled CLR in the DB. - Made sure the DB owner has UNSAFE ASSEMBLY permission. - Added the TRUSTWORTHY property to the DB. (Yes, this isn't the "correct" way to do it, but I didn't want to deal with code-signing voodoo. Apologies to actual believers in voodoo.) - Created an Unsafe assembly "MyAssembly" in SQL Server 2005 and Visual Studio 2005. - Created all the necessary Interop assemblies (by creating a normal (non-SQL) C# project and building my code, and raiding the bin directory). - Added these Interop assemblies to SQL Server 2005 as Unsafe assemblies. - In VS2005, built my SQL Project code and deployed successfully. - Tried running my stored procedure through a Query window, and I got the error above.
I've done many searches. All of the results I've found concern themselves with Web Services and XML serialization, and suggest using sgen.exe. I don't think they're relevant to my problem. A few said I should add my COM DLLs as assemblies to SQL Server, but that is impossible for native code DLLs. I found something that hinted at tblexp.exe, but I didn't understand how that could help me. I already figured out a way to get me the Interop libs.
Efforts at solving: - Reading webpages for hours on end. - I tried using sgen.exe to create the XML serialization assembly, but it didn't help. - I tried adding various native-code DLLs directly as SQL Server assemblies, but you can bet it didn't like that. - A few other pitiful attempts not worth mentioning. - Reading this forum. I didn't see anything that applied. - Posting here.
I really wish Microsoft had meant what they said when they stated that "Unsafe" assemblies can access anything, instead of trying to protect developers from their folly.
Any insights on getting those COM objects to work in my CLR stored procedure? Thank you.
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#.
I am trying to write a database compare application for our SQL Server databases using VB and SQLDMO.
I find SQLDMO to be rather slow but on large databases with about 800+ tables, this loop eats up all of my abundant memory until everything crashes. On smaller db's it works fine but is a slower than I expected.
Dim Tbl as SQLDMO.Table Dim Col as SQLDMO.Column
For Each Tbl in DB.Tables 'DB was previously set For Each Col in Tbl.Columns Debug.Print Tbl.Name & "." & Col.Name Next Col Next Tbl
Here's a pic of what the app looks like so far. If it looks useful to you, let me know, I'll give you a copy if I can get it working better!
I am using SQLDMO.DLL for Backup & restore utility in C# application.
Following is the code :

While running above code it gives following exception :
"[Microsoft][ODBC SQL Server Driver][SQL Server]Database in use. The system administrator must have exclusive use of the database to run the restore operation.[Microsoft][ODBC SQL Server Driver][SQL Server]Backup or restore operation terminating abnormally."
I have a program using SQLDMO object.When I use it on my computer and I have install sqlserverit works OK,but when I move the program to another computer without sqlserverthe program runs error the error message is com exception 80040154can the proram using SQLDMO running on computer without installing sqlserver?BTW: my System is win2003,and the other is windows xp
I need to install sqldmo.dll and related files - so I can use SQL Objects. I've been searching the Internet and trying for hours to register the file on XP Client machines - but not go.
I have put the following files in the locations below:
sqldmo.dll Program FilesMicrosoft SQL Server80ToolBinn sqldmo.rll Program FilesMicrosoft SQL Server80ToolBinnResources1033 sqlresld.dll Program FilesMicrosoft SQL Server80ToolBinn sqlsvc.dll Program FilesMicrosoft SQL Server80ToolBinn sqlsvc.rll Program FilesMicrosoft SQL Server80ToolBinnResources1033 sqlunirl.dll System32 w95scm.dll Program FilesMicrosoft SQL Server80ToolBinn
I have also tried putting the files in System32 with the appropriate subdirectories - still not go. I cannot seem to get this to work.
If anybody has successfully installed sqldmo.dll for use on SQL Server 2000 client machines running XP, I'd be really grateful for a few pointers.
IS there a component/way of retrieving a list of SQL Servers or databases on your local network for SQL 2005/Express. The same way sqldmo worked for a .net project.
