SSIS - Need To Reference .NET Assembly Without GAC
Jan 25, 2007
I have a .NET assembly that I need to reference and use within my SSIS script task.
The only way I can acheive this is to strongly name my assembly and put it in the GAC.
This is not possible as my assembly is already in production and uses other 3rd party assemblies that would also need to be registered in the GAC.
As a workaround, I have created a .Net console application that references my assembly, that call from a SSIS Process Task.
Does anyone know of another way I could use my .NET assembly within my SSIS package?
Any help appreciated.
Regards,
Paul.

I have an external reference to an assembly that uses the following external references of its own:
System
System.Data
System.Xml
In BIDS everything works without any issues so I decided to deploy the package to my database server. In doing so, I copied the DLL reference for my external assembly to obth the GAC and the v2.0.50727 folder and I even went as far as to copy the assembly folder into the Program Files folder.
Despite these efforts, I keep obtaining the following error:
The script threw an exception: Could not load file or Assembly 'MyComponent, Version-1.0.0.0,Culture=neutral,PublicKeyToken=f5bb784d481b2932' or one of its dependencies. The system cannot find the file specified.
I checked the version of my DLL in all 3 places and both the version and the token are the same.
I checked the properties within the script task and it has the exact same path to the v2.0.50727 folder (which shouldn't matter given the GAC...).
Does anybody has any ideas why this exception is occurring?
Thank you for your help!

When I run this ...
CREATE ASSEMBLY asmRANDRTCalendaringGateway FROM 'E:sqlRANDRTCalendaringGateway.dll' WITH PERMISSION_SET = UNSAFE
I get this error ...
Msg 10301, Level 16, State 1, Line 1

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: 2(The system cannot find the file specified.)). Please load the referenced assembly into the current database and retry your request.
Even though I do not explicity refer to system.web in the DLL's code ...

using System.Collections.Generic;
using System.Configuration;
using System.Text;
using log4net;

Is the problem just staring me in the face ?

Hi,
I am creating dataflow tasj using following
Imports Microsoft.SqlServer.Dts.Runtime
Imports Microsoft.SqlServer.Dts.Pipeline
Imports Microsoft.SqlServer.Dts.Pipeline.Wrapper
These refer to Microsoft.SqlServer.DTSPipelineWrap.dll and Microsoft.SQLServer.DTSRuntimeWrap.dll. While these assemblies were already there in my dev machine I don't find these files in production enviornment for SQL server 2005. I am refering these assemblies from following path in my local machine : C:Program FilesMicrosoft SQL Server90SDKAssemblies.
How to install these assemblies in prod env, offcource one option is to copy it and then put it in GAC thru script . Why does not it gets installed while installation of SQL server 2005. Are these assemly dependent on SP1 ?
Thanks

I have a custom assembly that uses a config file to obtain database connection settings. This dll is then used by my sql report. I have added refrerenced to all the required dll's in my report and added the required code groups to all the necessary files. I have also placed my app.config file in C:Program FilesMicrosoft SQL ServerMSSQL.3Reporting ServicesReportServer and C:Program FilesMicrosoft Visual Studio 8Common7IDEPrivateAssemblies
However when I actually run the report in the designer (vs2005) I am receiving Null reference exceptions when my code tries to read my config file because it is reading the machine.config file and not my app.config file. If I hard code my connection string everything works fine.
Can anyone tell me why the machine.config file would be referenced instead of my app.config file and how I can stop it from doing this?

I have a SSRS 2012 report which references a custom c# assembly.  This report exists in multiple environments (alpha, beta and  production ) which are each associated with different data sources.
Is there a way for the assembly to determine the datasource used by the calling report so it can also connect to it?

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 have a custom PipelineComponent that accepts a string of SQL. I don't have a custom UI, all I need is the Advanced Editor. Currently the SQL property is just the standard line of text that can be entered on the Advanced Editor. I would like to use the popup multi-line editor that the built-in components use for editing SQL. I was hoping it was the System.ComponentModel.Design.MultilineStringEditor but that is definitely not it (and that one is insufficient for entering more than a few lines of SQL). I'm assuming it must be a UITypeEditor that was shipped as part of SQL 2005, but I haven't been able to track down the qualified assembly name for it anywhere. I tried debugging in VS to get down to a IDTSCustomProperty90 that I could look at the UITypeEditor on, but no such like. I also tried using Reflector to see if I could dig up a string, but no luck there either as the pipeline components don't seem to have managed assemblies (I could've just missed them) and the control tasks (which happen to use the UITypeEditor I'm looking for too) seem to only be thin wrappers around COM interfaces. I scoured BOL and the WWW in general for a list of these assembly names, but looks like they're not out there either. Has anyone tried to find these before? Am I barking up the wrong tree, should I not be able to use these editors for copyright reasons?

What is the proper method of using the Excel.Interop assemblies with SSIS? I am using SQL Server 2005 Integration Services (VS 2005) against the .NET Framework v2.0.50727 with the Microsoft.Office.Interop.Excel.dll assembly.
I find that the referenced instance of Excel in my SSIS package is not always released from memory as expected. I'm not sure that I have a problem per se, but I am interested in knowing the Microsoft reccommended method of using the Office Interop assemblies with SSIS.
For this thread, "working" code is defined as observing the appearance and disappearance of the Excel.exe image in the Task Manager as it is created and destroyed in the SSIS package.
The following Sript Task code (between stars) works as expected in that the image of Excel can be seen created and removed from the Task Manager list of processes:
************************************************
Imports Microsoft.Office.Interop.Excel
Public Sub Main()
Dim mobjExcelApp As Microsoft.Office.Interop.Excel.Application
Dim mobjWorkbook As Microsoft.Office.Interop.Excel.Workbook
Dim objSheet as Worksheet
Dim strExcelFilename as string = "C:TempMyExcelfile.xls"
Dim strSheetname_ValidSamples as String = "Sheet1"
mobjExcelApp = New Microsoft.Office.Interop.Excel.Application
mobjExcelApp.Visible = False
mobjWorkbook = OpenWorkbook(strExcelFilename)
objSheet = CType(mobjWorkbook.Worksheets(strSheetname_ValidSamples), Worksheet)
strWell = CType(objSheet.Range("a1").Offset(intRow, 0).Value, String)
objSheet = Nothing
mobjWorkbook.close
mobjWorkbook = Nothing
mobjExcelApp.Quit
mobjExcelApp = nothing
System.GC.Collect()
System.GC.WaitForPendingFinalizers()
System.GC.Collect()
System.GC.WaitForPendingFinalizers()
End Sub
***********************
On occasion, when the line of code that sets the variable strWell (in BLUE above) is followed with the following line of code:
strSampleName = CType(objSheet.Range("a1").Offset(intRow, 1).Value, String)
the code will work fine with no errors, however, the Excel image is not removed from the task list. I have found that the instance will disappear upon waiting (several minutes or more).
Thanks,
Rob

I tried to access a dot net assembly (.dll) file in ssis script component using following steps.
Create new Script Task in Data Flow Task
Edit Design Script button-> Loads script Project in MS VSA
Locate Object Browser
Select Custom Component Set from the dropdown and hit browse button
Browse and place the custom component dll (This Custom component dll has to be in GAC - Global assembly cache before browsing)
Select the namespace from the Component list of the object browser and click on €œAdd to references to Selected project in the solution explorer€? button
Write Imports <namespace> in the script code to invoke class methods from the .NET custom component
The following steps worked properly with June CTP version of yukon.In september CTP version of Yukon in SSIS when i browse the dot net assembly with the same above steps i get a error stating " The file could not be browsed ".Can anybody help me in the same.

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

Hi, I have heard alot of people talk about using C# for scripting withing SSIS and the answer to that question is no apparently. You can only use VBA but there is no extensive or in my respect any documentation as reference for using VBA in SSIS. I am new to VBA because i used to use jscipt and vbscript in early version of sql server. But in order to learn using VBA, I need to learn it in which there seems to be no reference in relation to SSIS. All the VBA references you find are in relation to MS Office. Is there anything i am missing or can someone show me where to go as my reference for VBA in SSIS. Its bad enough to change the scripting language but worse not to provide any reference materials for uses to get up to speed.

Hi ALL
I cannot add the reference to the following:
"Imports Microsoft.AnalysisServices.AdomdClient"
in SSIS script task. All the objects that i declared become underlined because there is no reference to the above library.
When i go in SSIS script task and open the code to add the reference it does not the list the above library.
I am able to add reference in Visualstudio but not in SSIS.
Please adivse, it is very critical and urgent for my task
Thanks.

Consider the Conditional Split task. I can use a C-like language to create statements such as
Ltrim ([Col1] =€?A€?) || Ltrim([Col1] =€?B€?)
This sure ain€™t VB-like and the list of functions in the upper right-hand pane of the task (€œexpression editor€?) does not help me construct such statements.
Where is the reference manual describing this language?
TIA,
Barkingdog
P.S. I have found fragments in BOL but the info does not seem complete and the BOL topic fragmentation impedes learning.
P.P.S. Why MS uses this language instead of VB.NET, which they use in their Script tasks, is beyond me.

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.

Hi All,
OK, so I have an SSIS package that I build using the "test" database as the destination. Now I want to execute it using another database as the destination. This is basically for an installation script where the source is always the same, an access database.
So here I have:
"C:Program Files (x86)Microsoft SQL Server90DTSBinnDTExec.exe" /file e:data_import.dtsx /CONNECTION DestinationConnectionOLEDB;""Data Source=(local);Initial Catalog=Test2DB;Provider=SQLNCLI.1;Integrated Security=SSPI;Auto Translate=False;""
Which works (sort of). It does try to import the data into "Test2DB", but what happens is all of the destination tables in the dtsx package have names like [test1db].[dbo].[tablename]
So my question is: is there a way to remove the databasename reference in the table names for all 195 tables in my database without doing it manually?
Thanks in advance.

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've created my own posting for this. The original post was here, I apologize: http://forums.microsoft.com/forums/ShowPost.aspx?PostID=2906512&SiteID=1
According to the poster it's not possible. But there has to be some way to do it? Reflection (don't know how)?
I need to get a reference to the task host in an SSIS Task component.
Basically the scenario is this:
I have a custom task I have created. However I would like to validate that the ExecValueVariable is infact a string variable during the validate event of the task. I know how to verify its a string variable. But I can't figure out how to read what the user selected (such as User::Myvariable). The only way I've been able to figure out how to do it, but it only works if you open my custom task UI.
What I did is this:
I've implemented IDtsTaskUI and during the initialize section I wrote:
Sub Initialize(ByVal taskHost As TaskHost, ByVal serviceProvider As IServiceProvider) Implements IDtsTaskUI.Initialize
' Store the TaskHost of the task.
Me.taskHostValue = taskHost
Dim myTask As CustomTask= CType(taskHost.InnerObject, CustomTask)
myTask.myTaskHost = taskHost
End Sub
My Task is named: CustomTask. I have a public variable in my task as follows:
Public NotInheritable Class CustomTask
Inherits Task
Implements IDTSComponentPersist
Public myTaskHost As TaskHost = Nothing
Therefore I pass back the taskhost value to the CustomTask class, and voila I have it.
Problem is, this only works if the custom task calls the initialize method, and this only happens when you open the custom editor.
I then do the validation in my CustomTask class and it works fine, but myTaskHost is null/nothing until you actually open the custom task UI
How do I solve this?

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.
