Triggers Calling WebServices
Mar 16, 2006
Yes, I know there is at least one other thread about this type of thing, but my error is a bit different............
I have been trying to call a webservice from within a trigger and i keep receiving the following error:
Msg 6522, Level 16, State 1, Procedure wepTestTrigger, Line 1
A .NET Framework error occurred during execution of user defined routine or aggregate 'wepTestTrigger':
System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.EnvironmentPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
System.Security.SecurityException:
at System.Security.CodeAccessSecurityEngine.Check(Object demand, StackCrawlMark& stackMark, Boolean isPermSet)
at System.Security.CodeAccessPermission.Demand()
at System.Net.CredentialCache.get_DefaultCredentials()
at Triggers.wepTestTrigger()
.
The statement has been terminated.
How or what do I need to do in order to call this webservice?
Thank you for any help.

I'm assuming it's possible to call a web service asynchronously from a SQL CLR function, is this correct or is there a fundamental flaw in calling the asynchronous methods?
I've tried coding a sample and despite creating a new thread, which in turn calls the web service asynchronously and using newthread.join I can never get the webmethodasync_completed sub to be called.

Hey guy and gals,
I need to connect to a web service from a Sproc, can this be done? I've google and found out about Httpendpoints but that is running the web service on the server, not connecting to one from the server in a sproc. Any ideas or site links would be helpful. TIA.

Hello, I appeal to all to save me from this situation.
I have a WebService in VB.net by IIS and a operation to connect to the SQL server and run a query and others operations. All fine...
But after a certain time only the SQL operations don't respond nothing, the others are OK. So the problem is not in the IIS i think and something between the IIS and the SQL Server.
Can you give me some light about this PLEASEEEE :D ?
Thanks
If any of you need the source say it.
Thanks

If the web service is talking to a SQL Server database and the authentication used is SSPI (Security Support Provider Interface
) / windows authentication, does the ASP.Net user or machine id user
need to be added to the list of allowed ids to the database server? Or
am I misunderstanding the security constraints?
If I run my code through an Nunit test conduit, I can retrieve data,
but If I run it through my webservice it fails authentication.

Hi,
I need to expose data in a SQL server 2005 database as a webservices. I have 2 options to choose. I can create an End point in sql or build a webservices in .NET.
So what are de advantages and disadvantages of those 2 approaches ?
Of course they want the webservices secure. I know that authentication is not a problem since we use windows integrated security for the intranet. But what will happen if we move to an extranet or the internet ?
But how do you enable authorization ? and Context security ? Is context security better done in .NET then in SQL ?
Thanks in advance.

Hello everyone,
I am newbie in SSIS and I have one problem.
I have defined in Control Flow one WebService Task, specified the WSDL-File.
I have chosen one method from WS as Input. But this method requires one parameter of the ArrayOf_xsd_string type.
If I try to choose it, I receive following error:
===================================
This complex type does not contain any properties. (Microsoft.SqlServer.WebServiceTaskUI)
------------------------------
Program Location:
at Microsoft.SqlServer.Dts.Tasks.WebServiceTask.CustomGridControl.HandleEllipseBtn(Int64 row, Int32 col)
in my WSDL-File it already defined:
Code Snippet<complexType name="ArrayOf_xsd_string"><complexContent><restriction base="soapenc:Array"><attribute ref="soapenc:arrayType" wsdl:arrayType="xsd:string[]"/>
Could you help me? Where I can define this ArrayOf_xsd_string type, or how can I correct my problem?
Thanks a lot for your Help!
Regards,

I developed a java proxy application for SSRS(Sql Server Reporting services) and able to render the reports by making webservice calls to SSRS webservices. But I am getting the data for the complete report. How can I get only a partial report( like page by page as we get in the Report Manager)? Which parameters should I pass.
As some of the reports are too big, the java application is getting memory issues and I want to limi the data that I get from SSRS.
Appreciate your suggestions.

I developed one DLL in vb .Net which call two web services (sql endpoints) I wish to use this solution but for hundreds of servers (endpoints) I want to ask if I could do that with dynamic parameters passed to de DLL CALL in sql server clr.
Actually when I compile de DLL I need to have referenced (hardcoded) the webservices (endpoints) and when I need a brand new endpoint I need to reference it, compile the dll and release.
I cannot find how to invoke the service within the DLL with the namespace or webservice name as parameter.
Mi code to invoke now my referenced end point is: (note that my endpoint name is rperez)
Dim CallWebService As New rperez.IntelisisServiceEndPoint
CallWebService.Credentials = System.Net.CredentialCache.DefaultCredentials
Call CallWebService.IntelisisService(ArchivoOriginal)
My class rperez.IntelisisServiceEndPoint is referenced (hardcoded) in the dll project I need it dynamic
Do I need to change my code to PROXY object ?

I have requirement to update/insert the DPID based on the address which are passed as an input values.There are more than one address at the same time and I configured to get the address from the query which are correct and output of the address values will be stored as system object variable.I am then passing the system object variable to for each loop container and I have configured the collection and variable mappings as a variable for each input value.
when I pass the value manually to the web service task it works correctly.When I pass it as a variable to web service task it doesn't return any value.I have a data flow task which converts the ouput from web service task using the xml source converts it to oledb destination.I don't see any rows being written to the target table.

This isn€™t an problem as such, it€™s more of a debate.
If a table needs a number of update triggers which do differing tasks, should these triggers be separated out or encapsulated into one all encompassing trigger. Speaking in terms of performance, it doesn€™t make much of an improvement doing either depending upon the tasks performed. I was wondering in terms of maintenance and best practice etc. My view is that if the triggers do totally differing tasks they should be a trigger each on their own.

Hi all, i have a DTS package that i call from a C# app, i had it working great until i decided to use an activeX script to do the data transformations instead of the row copy. I need to use ActiveX to add a standard name to the last column in the destination table. the problem is the task is executing without errors (from c#) but nothing is happening, its failing silently. If i modify the Data Transformation back to a standard column mapping (with separate DTSTransformations for each column) it works fine, but as soon as i use activeX to handle the transformations it doesn't work. Can anyone tell me what i may be doing wrong. heres the calling code from C# if(f.Name.Substring(13,7).ToLower() == "product")
{
try
{
activity.Log("Starting Product DTS Package...");
DTS.Package2Class package = new DTS.Package2Class();
object pVarPersistStgOfHost = null;
package.LoadFromSQLServer(
"192.168.8.8",
"username",
"thepassword",
Microsoft.SqlServer.DTSPkg80.DTSSQLServerStorageFlags.DTSSQLStgFlag_Default,
null,
null,
null,
(string)ConfigurationSettings.AppSettings["productDTSPackage"],
ref pVarPersistStgOfHost);
package.GlobalVariables.Item(1).Value = f.FullName.ToString();
package.Execute();
package.UnInitialize();
//force release of COM object
System.Runtime.InteropServices.Marshal.ReleaseComObject(package);
package = null;
}
catch(Exception e)
{
activity.Log(string.Format("Failureprocessing {0}",WorkingPath + f.Name) +" - "+ e.Message);
} and the activex i tried to use for the transformations is: '**********************************************************************' Visual Basic Transformation Script'************************************************************************' Copy each source column to the destination columnFunction Main() DTSDestination("Yesmail Id") = DTSSource("product series") DTSDestination("Customer CKM CustId") = DTSSource("product family") DTSDestination("Product SKU") = DTSSource("transaction date") DTSDestination("product model name") = DTSSource("serial number") DTSDestination("serial number") = DTSSource("product model name") DTSDestination("transaction date") = DTSSource("Product SKU") DTSDestination("product family") = DTSSource("Customer CKM CustId") DTSDestination("product series") = DTSSource("Yesmail Id") DTSDestination("fileName") = DTSGlobalVariables("sourceFile").Value <-- this is why im using the activex for this field to get a Global Variable. Main = DTSTransformStat_OKEnd Functionthe weird thing is the PACKAGE runs fine from ENTERPRISE MANAGER with this activex, it just doesn't do it from my Calling app, perhaps i have missed something i need to change in the package constructor? BTW: i do have my assembly signed in C# for the COM wrapper.thanks in advance, mcm

I'm developing a new Stored Proc that will be taking information in to enter customer and order info. Looking at the current Stored Proc its using alot of If statements and I'm thinking of breaking the sp up into different Stored Procs and calling them all from One main stored proc. I know how to do this but I was wondering how it would effect performance. So should I simply keep all the stuff in one proc or module it out into multiple ones to make it easier to follow and read?
Thanks

I'm working in SQL Server 2005. I have an existing SP that does exactly what I need (it's the aspnet_UsersInRoles_IsUserInRole SP). I want to reuse this SP and use it's return value as a field in the SP I'm writing. How do I go about doing this? I could take the logic out of the called SP and wrap it in a function; but, I would really like to reuse the SP aspnet_UsersInRoles_IsUserInRole. Thanks in advance for any assistance.

Is it possible to achieve this using triggers:When someone tries to delete a row in table A, the trigger should first delete a corresponding row in table B and then delete the row in table A. The reason being that, there is a foreign key set on Table B that references table A. So any attempt to delete a row in table A without deleting the corresponding row from B, throws an error.

I need to create a set of rows every time a new row is inserted into a table.
Example (I think this would work)...
select @insertedId = column1 from insertedselect @id = column1 from table1 where column2 in (select column1 from table2 where column2 = @insertedId)insert into table3 values(x, y, @id)
Is it possible to do the same kind of thing in a situation where the select statement returns multiple values and execute the insert statement for each of these values?
Also, if table3 was in fact the table on which the trigger acts, would it then be executed for every row created by the trigger?
Sorry if I sound confused. I am.

Hi All,
I'm using triggers to handle my transaction log to cature inserts and updates. It works fine except if the user clicks on the Save button more than once, the trigger is fired and the record is written to the log even if the record wasn't changed. Does anyone know how to check if the record was actually changed so that it isn't written to the table if it wasn't?
Thank you,
Mike

When I execute a stored proc from my asp.net page, will the results of a trigger be returned to my program?
For instance say my stored proc is:
Update Employees set
(Lastname = @Lastname)
where ID = @ID
And my trigger is:
CREATE TRIGGER tr_Employees_U on Employees FOR UPDATE AS
IF UPDATE(lastname)
BEGIN
RAISERROR ('cannot change lastname', 16, 1)
ROLLBACK TRAN
RETURN
END
GO
It seems like since this is an AFTER trigger that my webpage would actually get a valid return code from my stored procedure however the trigger would rollback those changes correct? Or would the trigger get fired and send it's return code to my webpage?

I'm a bit confused on this bit please elaborate : " FROM Test_TRG t INNER JOIN inserted i ON t.PK = i.PK ".
The PK is on which field? Basically this trigger should ensure that on insertion of o new loan if
The left(loan_no,3)=MCG and its null then NEWMCG
left(loan_no,3)=MCG and its null then NEWMCG
left(loan_no,3)=KVS and its null then NEWKVS
left(loan_no,3)=MFS and its null then MFS
left(loan_no,3)=TCR and its null then TCR
left(loan_no,3)=ABL and its null then ABL
Listed below is what l've tried to do but l'm missing the PK part.Otherwise everything else you explained
in the script is clear. Thanks man its urgent. When l parse the query its fine , but When l run it
l get an error.
CREATE TRIGGER UpdTest_TRGData
ON Test_TRG
FOR INSERT, UPDATE
AS
UPDATE Test_TRG
SET LoanBook = CASE WHEN LEFT( i.Loan_No, 3 ) = 'MCG' THEN 'NewMCG'
WHEN LEFT( i.Loan_No, 3 ) = 'KVS' AND i.LoanBook IS NULL THEN 'NewKVS'
WHEN LEFT( i.Loan_No, 3 ) = 'MFS' AND i.LoanBook IS NULL THEN 'MFS'
WHEN LEFT( i.Loan_No, 3 ) = 'ABL' AND i.LoanBook IS NULL THEN 'ABL'
WHEN i.LoanBook IS NULL THEN LEFT( i.Loan_No, 3 )
END
FROM Test_TRG t INNER JOIN inserted i ON t.PK = i.PK
-- Fill in Primary Key or other Join Column(s)
WHERE LEFT( i.Loan_No, 3 ) = 'MCG'
OR ( LEFT( i.Loan_No, 3 ) = 'KVS' AND i.LoanBook IS NULL )
