Calling External Webservice Using Certificate
Apr 28, 2006
I'm trying to call an external webservice which use https and certificate. I load certificate into MSIE and then made *.cer file. The problem is that if I compile simple console program which use this certificate - than all is OK. But when I compile simple rutine for SQL server and trying to run it - an exception is issued after this line:
service.ClientCertificates.Add(X509Certificate.CreateFromCertFile(certFile));
Exception is:
Request for the permission of type 'System.Security.Permissions.FileIOPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
Do you have any advices?

Is it possible to access a webservice from within SQL 2005?What I am looking to do is place a trigger on a specific table, and detect if a specific column is being updated. If it is, I want to launch a robust process that does x, y and z. Something like this:1) record is updated indicating that an account is closed.2) SQL launched a webservice/ aspx page that builds an HTML email template and then mail it.thanks!

I have a webservice that I would like to call from SQL Server 2005. I have done alot of testing and am pretty familiar with how CLR works and how to create assemblies in SQL. My problem is that I don't know much about .net and am not sure what kind of project I need to create in Visual Studios to accomplish calling the webservice. I've tried googling and have not found much that is of use to me.
Any help would be appreciated

Hi,
I created a method in the webservice which will take productid as input parameter and return the product number, productname, and vendor account number and vendor name. I was able to run the web service successfully. And also created the assemblies and sp using these assembly.
At the final execution i am getting some security exception
The following is the exception I am getting€¦.

Hi,
I need to call a web service (consume a webservice)from a T-SQL stored procedure. Is there a way to do this. If not is there a way to make a simple http request, something like a utl_http in oracle.
At the moment iam using a MSSOAP30.SOAPCLIENT object created using sp_OACreate to make this call. However this means that the soap toolkit be installed on the pc on which SQL server is installed. I was hoping to find a completely independent way.
Also when i call sp_OACreate where does sqlserver 2005 look to find that object. Iam thinking of putting the MSSOAP30.dll on that machine, if all else fails.

Hi!
I am developing an integration solution for MS CRM.
The basic idea is to have a CLR stored procedure that draws data from a SQL database, transforms the data, and then adds it to MS CRM via the webservice.
When executing the stored proc, it randomly fails (although at approximately the same time, everytime).
This is the error message:
Msg 6522, Level 16, State 1, Procedure add_CCU_information, Line 0
A .NET Framework error occurred during execution of user defined routine or aggregate 'add_CCU_information':
System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: Only one usage of each socket address (protocol/network address/port) is normally permitted
System.Net.Sockets.SocketException:

If someone could please give some advice, I would really appreciate it.

I am searching for a solution for Calling or consume a web service in SSIS through Script task. I have gone through so many links but i am able to find the exact solution. I am getting so many references, though i am unable to crack it.
My requirement is i need to call a web service URL through script task which is having a client certificate. When we are trying to connect to the URL it will ask for the certificate authentication. After calling this URL we will get a WSDL file from the web service, We need to consume that WSDL file and we need to identify the methods inside this WSDL and need to write the data available in this WSDL to the data base tables.
How can we call that web service URL( With certificate) through script task and how can we read the WSDL file and How we can load the data into DB table.

Hi,
Is there a stored proc or a function I can call from Query Analyzer to execute another .EXE and return when it's finished?
I'd like something like
SET @RET = sp_CallEXE('c:mypathmyprogram.exe myparameters')
(Except for the name of the function, there should be something that does this right? I mean, DTS does it already so it must be referring to a function or a SP.)
I want an answer to so that I can validate that everything went well (hence the @RET variable)
Thanks,
Skip.

Can you put is a call withing a Data Flow that will call an External Application and pass a parameter to that application IE say a command line app and then take the output and assign it to back to the flow as a "column" or whatever for that row... IE I want to take a value push it to an external app and then the output from that app I want to insert it into another field for that row in the new table I am moving the data to.

we've seen the ease of calling sqlclr stored procedures whose parameters are known sql data types but are wondering what we're in for when we wish to pass .net objects to a sqlclr stored proc. We're confident that the sp's external assembly itself would build if instructed to "receive" .net objects etc, but can't envision how/if the sp's signature would generate nor can we imagine how such an sp would be called. We're not even sure we can envision how another sqlclr object (eg a trigger) would pass .net objects to the sp. Are we faced with using user defined data types if we need to pass .net objects to such sp's?

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?

Hi, We are trying to implement Service Broker between SQL Server Express and SQL Server on the Same machine and we are having problems with certificates. We are creating a certificate on SQL Server, backing up the certificate on a file system and then loading certificate on the SQL Server Express from the file and we are keep getting the following error: Msg 15208, Level 16, State 1, Line 1 The certificate, asymmetric key, or private key file does not exist or has invalid format.
Following script runs fine on SQL Server.
Code Snippet
use master
Create Master Key Encryption BY Password = '45Gme*3^&fwu';
BACKUP MASTER KEY TO FILE = 'C:ServiceBrokerPrivateKeyMasterB.pvk'
ENCRYPTION BY PASSWORD = '45Gme*3^&fwu'
Create Certificate EndPointCertificateC
WITH Subject = 'C.Server.Local',
START_DATE = '06/01/2006',
EXPIRY_DATE = '01/01/2008'
ACTIVE FOR BEGIN_DIALOG = ON;
BACKUP CERTIFICATE EndPointCertificateC
TO FILE = 'C:ServiceBrokerEndPointCertificateC.cer'
Following script runs on SQL Server Express:
Code Snippet
Create Certificate EndPointCertificateC
From FILE = 'C:ServiceBrokerEndPointCertificateC.cer'
WITH PRIVATE KEY (
FILE = 'C:ServiceBrokerPrivateKeyMasterB.pvk',
DECRYPTION BY PASSWORD = '45Gme*3^&fwu'
);
If we run the script other way around, it works fine. If we use the SQL Server on some other machine, the script works fine. But only on the same machine, it throws this error. We made sure the permissions and everything. Let us know if there is any work around or what are we doing wrong.
Any help is appreciated. Thank you,

I created a custom DTS object that does its work by calling awebservice. When you create the object in DTS, it lets you set theuser/pw you want to use to authenticate to the webservice. The problemI am having is that once I authenticate to the webservice within DTS,it always uses the same authentication when contacting the service.So, for example, I drop a new instance of my object into a package. Itconnects to the webservice as me. I set up the parameters of the task,including telling it to connect as User="test". If I run it, my codesets the credentials correctly on the webservice, but the webservicestill gets called as me.If I exit out of SQL Server and go back in, and run it, it correctlyconnects as User="test". But then if I try to edit the task, and givemy own user and password, it still always tries to connect as "test".It seems whoever I initially connect to the webservice as, that is theinformation that DTS will use for the entire session.Is there any way to do what I want to do?thanks

After creating a WebService using SQL Server 2005 HTTP Endpoints I can only browse to the wsdl file using localhost address and not via the machine name
For example http://MACHINENAME/SomeWebService?wsdl will ask for some authentication that can never be determined while
http://localhost/SomeWebService?wsdl will successfully generate the WSDL file
This happens on the actual machine and on all other machines in the domain which pretty much defeats the purpose of using Web Services to expose functionality.
Does anyone have any idea regarding
(a) what security features are at work here,
(b) Where are they documented
(c) How to set or use them in such a manner as to actually be able to use web services.
While investigating I have noticed that all examples conveniently use localhost and so either avoid or never address this issue.
Any suggestions appreciated.

I have noticed what seems to be a bug in Reports using an XML Webservice for a datasource.
I have the data source setup and working to query an XML webservice. All fields aren't always populated - so after the intial step that automatically builds your dataset and sets up the field names - I went in and manually added the remaining missing fields (which were blank).
Then I setup the report - dragging/dropping fields from the dataset.
I thought everything was working fine, UNTIL i noticed that IF the FIRST record contains ANY blank fields - ALL of those fields (on every record returned) show blank on the report.
For example my webservice might return something like this:
Code Snippet
<Root>
<Parent>
<Child_Name>Joe</Child_Name>
<Child_ID></Child_ID>
</Parent>
<Parent>
<Child_Name>Tim</Child_Name>
<Child_ID>123456</Child_ID>
</Parent>
</Root>
But when my report actually runs, it doesn't show any value for the second record:
My Report
Child_Name Child_ID
Joe
Tim
In this case, Tim should actually show the Child_ID value, but apparently because the first record didn't have a value - the report assumes NO RECORDS will have a value and doesn't bother printing them.
But if I run the report so that the first record DOES contain that field - then everything seems fine.
I can see that my Dataset hasn't changed - as it still contains all the fieldnames (even the ones that sometimes return empty).
Am I doing something wrong?

I just try to implement the 3 tire architacture. So, I developed the one web project for web ui and one web service and one dall project in one solution.
On dll project put the bll, connect to sql server and return the result set to web service.
Form web service, get the result from dll and transfer to web ui.
When I call class from dll, i just overrid the connection string.
Actually it's wrok properly in my development pc and in my local webserver.
As our usual, when i publish to real web server i got the following error.
Server was unable to process request. ---> An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
Anybody plz help and direct how should i fixed this problem.

From DB Server, I am not able to invoke the webservice present in the app server. But i am able to browse the webservice from my db server.

We have a package that runs a webservice. The webservice connects to exchange for multiple mail accounts so it sometimes takes awhile to run.
If run from SQL Server Management Studio, it usually completes, but may occassionally time out.
If run from a job (i.e. we want this scheduled) then it NEVER completes successfully - althought there is very little information about what the error was. It seems to fail too quickly to be a time out error...
Any idea why this is happening? Or how to prevent it from timing out? Is there a way to initiate the webservice asynchronously from SSIS?

Hello all,
When trying to configure a WCF service as a report data source I have these following questions:
1. What do I need to provide for the connection string?
I currently wrote http://localhost:8003/ServiceName/ which returns the WSDL. Is that correct?
2. I don't know what to write inside the Query defintion. I currently wrote:
<Query>
<SoapAction>
http://tempuri.org/ServiceContractInterface/MethodName
</SoapAction>
<Method Namespace="http://tempuri.org/ServiceContractInterface"
Name="MethodName">
</Method>
</Query>
and the result is:
Failed to prepare web request for the specified URL. (Microsoft.ReportingServices.DataExtensions).
Can any one please point me in the right direction?!
Thanks.

We have a large number of applications that use various sql databases. They need to validate and do lookups of information such as employees and addresses. Currently, we load data from oracle into our main sql server and push the data out to various servers. This could perhaps be simplified with replication, but is now done with some dts packages.
We are wondering if there could be a better way to do this. We would like to go directly against oracle for the address data and to sql for the employee info.
An idea I had was to have our programmers create a web service that could be called from our .net applications. That works fine for in house applications, but some vendor applications need to see a table or view. We can write a CLR proc that can connect to the web service and provide data in table format I believe.
How could we get this into a view? I've tried creating a function that calls the proc and returns the table-valued variable to the view, but it seems the functions doesn't like using 'exec myProc' in the select_statement parameter.
I suppose we could have them make an additional connection to the lookup information, stored on a central database...they are probably doing this anyway to get to the validation db on the same server.
