Connecting To Webservice From DTS
Jul 23, 2005I 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

Aug 30, 2007I 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.

WebService Only Available To LocalHost
Apr 8, 2008After 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.

Bug With Report Using XML Webservice
Apr 25, 2008
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 Can't Connect To SQL Server From WebService.
Apr 24, 2008I 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.

Invoking Webservice Using SQL CLR Procedure
Jan 27, 2008Hi,
I have written a SQL CLR procedure, which will be invoking the webservice..I developed the application locally and it works fine, I am able to invoke the webservice using the SQL CLR procedure present in my database. But when i hosted the webservice in App server and executed the SQL CLR procedure in DB Server.
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.
I am getting the foolowing error message
A .NET Framework error occurred during execution of user defined routine or aggregate 'usp_LoadView':
System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond

SSIS To Run A Webservice Times Out
Oct 24, 2006We 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?

Getting Webservice Results Into A View
Mar 25, 2008We 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.

[Web Service Task] Error: An error occurred with the following error message: "Microsoft.SqlServer.Dts.Runtime.DtsRuntimeException: The type of the value being assigned to variable "User::WebserviceResult" differs from the current variable type. Variables may not change type during execution. Variable types are strict, except for variables of type Object. ---> System.Runtime.InteropServices.COMException (0xC001F009): The type of the value being assigned to variable "User::WebserviceResult" differs from the current variable type.

so i changed the Datatype of my package variable to String... the task then succeeds, but the Variable is empty?
Edit: i changed the return type of the webmethod to int and tried to receive the return value into int16, int32 and int64 package variables.. none of it worked...same exception as above
thanks for your help

Calling Webservice From A T-SQl Stored Procedure
Oct 6, 2006Hi,
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.

I'm using the SetReportDataSources-method to chang it. It works fine. After that i render the report and write the stream to database.
But. Now I developed a report using a SubReport and i want the SubReport to use the same data source like MainReport. But the reportserver doesnt overwrite the datasource to the subreport.
