Typed Endpoints In SQL 2005?
May 18, 2007
Is it possible to return typed data in an Endpoint for an ASP.Net Web Reference to Proxy? If so, is there any specific terminology I should be aware of to target my search?
I realize there is a choice between Object (returns a dataset or error) or dataset, but the automatically generated WebReference Proxy in ASP.Net (2.0) is untyped and we can't change the typing there as you have to remove the entire WebReference to pick up new WebMethods (or changes to signitures I'd assume).
I'm able to create my own typed proxy as a psuedo-DAL assembly which takes the WebReference and cast rows/objects into typed rows/objects one at a time, but this seems like a lot of work and probobly not the best practice.
Any help would be greatly appreciated

I am new to web services and as a DBA I only have limited .net experience. Our development team is creating a web services interface for our new IVR phone system, and we've decided on a solution that will send each of the phone call parameters from our database to the phone system in an XML based on line number and extension. I've found that Http Endpoints in sql server will be a perfect solution for exactly that and I won't need any .net to develop it. Thats the good news. There are, however, other requirements for our phone system to communicate back to our database. All of the examples I've seen for endpoints use a stored procedure performing a select statement.
Is it possible to create an endpoint that references a stored procedure performing an insert or update? To be more specific, can I create an endpoint that references a stored procedure that has parameters? If so, how do I pass those parameters through a web service request? Is it as simple as adding &variable="value" to the url?
If so I could develop this entire solution from the database side and not involve our .net programmer!
Another alternative: the phone system does have it own database in sql server. I'm not sure if our phone system provided can or will do this, but if they are willing to work with this, maybe a service broker can fit into this solution.
I look forward to any response. Thanks!

When I constructed my endpoint:
CREATE ENDPOINT MyNewEndPoint
STATE = STARTED
AS HTTP
(
PATH = '/MyEndpoint',
AUTHENTICATION = (INTEGRATED),
PORTS = (CLEAR),
SITE = 'arkansas'
)
FOR SOAP
(
WEBMETHOD 'GetSession'
(NAME='MyDB.dbo.spGetSession'),
BATCHES = DISABLED,
WSDL = DEFAULT,
DATABASE = 'MyDB',
NAMESPACE = 'http://MyDB/MyEndpoint'
)
the site is hardcoded. But, when I'm getting ready to deploy I'll need the site to be my production site. Is there an easier way to accomplish this then to edit the script each time before delpoyment?
TIA,
Dave C.

Are HTTP Endpoints able to be reached by another application that does not run on the same network?
For example, we have a partner that has a Web Application that would like to retrieve data from our database. We would like them to call a SOAP method through the Endpoint and in essence let their Web Application consume the Web Service. Is this possible?

I tried asking a similar question over at the asp.net, but I'm not getting any replies.
I created an endpoint in SS 2005 using DIGEST authentication, and I was successful in adding the web service to my project and getting results from a call to it.
However, the production environment does not exist in a domain environment, which eliminates even DIGEST (which requires a valid windows domain logon).
But, when I create the endpoint using BASIC authentication, I can no longer "find" the service. SS says the command(s) completed successfully after the Create Endpoint command. As a test, the documentation says that you can enter the http site into IE and the WSDL will display. And that works in digest mode. However, I've tried both:
http://<server>/path?WSDL and
https://<server>/path?WSDL
And neither returns the WSDL in IE (nor can it be added to my project as a web service).
I'm hoping someone has some ideas on how I can resolve this problem.
TIA,
Dave

Hi All,
I have mirroring set up in a test environment and it works great however I need to know/understand how the endpoints are encrypted. I have them set to use the AES algorithm; however I can not tell from BOL what keys they are using. I know the service master key is the root encryption key and endpoints sit at the server level (same level as service masterkey) but I am not sure if the endpoints use it to perform the encryption or not; do they and if not what do they use?
Thanks in advance,
Coleman

Hi,
I am trying to use a SQL Endpoint in my SQL 2005 DB to retrieve information from my C#.Net program. It works fine for me when I run it, but I am set as an administrator in SQL Server. When I try to run it as a normal/test user, I get the error message: "There was an error in the incoming SOAP request packet: Client, Endpoint, UnmappedSoapMethod."
Now, I have set up the endpoint in SQL and I can see the method I am trying to call when I do a select on the sys.endpoint_webmethods table. I have also allowed the domain group which the test user is a member of execute permission to the stored procedures and Access permissions to the endpoint.
What have I missed in the set up for me to be receiving this error message?
Cheers and thanks in advance.
Sam.

I am trying to expose a stored procedure on SQL Server 2005 as a web service. So I just have an end point created with the procedure as my web method. Now when I try to reference this web service in my C# windows application, I am only able to see the procedure definition by requesting for the WSDL http://servername/path?wsdl. But when I try to reference it, I get the error 501/505 - Not Implemented or not supported. Any ideas what the issue here could be? Would really appreciate the help here as I am kinda stuck! - Thanks, Manmeet

Hi,
I'm looking into hosting SQL Server endpoints on Vista. Unfortunately they don't work nicely because, as far as I know, they require http.sys which is part of Windows Server 2003. Hence, I can create my endpoint but i can't browse to it over http.
So, siple question (not so simple answer) how can I access SQL Server endpoints on Vista?
Thanks
Jamie

i have posted here a few times on my endpoint issues but i cant find a resolution so im approaching the issue from a different angle. can you guys tell me how you create and consume endpoints, preferably with the endpoint code, the url you use to see the wsdl, and any network/pc settings you may have altered to get endpoints to work. im looking for tips or steps that may not be included in basic endpoint tutorials. I really am stuck and have no idea what else to try. thanks all

I have a DAL that uses Typed DataSets (not directly, the DAL references and calls the dataset methods) and I am receiving a "There is already an open DataReader associated with this Command which must be closed first." error when I render an ASP.NET page where two imgs need to retrieve two different versions of an image (a thumbnail and a full sized image).I am using SQL Server 2005, ASP.NET 2.0, and my connection string includes the MARS attribute set to true. This is the method in the SqlServer DAL, _images is a typed table adapter:public override Image SelectImage(Guid? id) { // TODO: Find out why MARS feature isn't working! DataSet.ImageDataTable dt = _images.SelectImageById(id); <-- Exception occurs here if ((dt != null) && dt.Count == 1) { DataSet.ImageRow row = dt[0]; Guid? keyId = null; if (!row.IsKeyIdNull()) { keyId = row.KeyId; } // Success return new Image(row.Id, keyId, row.Path, row.Caption); } return null; } // This is the method that is called for both images, which calls the DALpublic class EntitySearch{ public static Image ImageById(Guid id) { return _dal.SelectImage(id); }}// These are the code-behind methods that the image response strings will come from...imgThumbnail.ImageUrl = String.Format("../Services/ImageBroker.aspx?img={0}&mode=Thumbnail", image.Id);imgFullImage.ImageUrl = String.Format("../Services/ImageBroker.aspx?img={0}&mode=Image", image.Id); // And finally here is the code in the broker class that saves the images to the response streamImage image = EntitySearch.ImageById(imageId);using (Picture picture = (mode == ImageMode.Image) ? image.Picture : image.Thumbnail){ Picture.Save(response.OutputStream, ImageFormat.Jpeg);}So the final snippet of code is being called twice, and it crashes. I have tried closing the connection and reopening it as a workaround but this only yields strange results, though it intermittently does load the images.Can anyone spot the issue?

Hi,
Is there any work around to passing a set of strings to a parameter in a Typed Dataset for example I am pasing '4226222172004','4212012182004' which I build on my code the number of items will vary passed on the user selection but since the Typed Dataset uses sp_executesql and the parameters are change to '''4226222172004'',''4212012182004'''
Any ideas how I can format the Parameter I am passing.so that it will end like where in ( '4226222172004','4212012182004') instead of where in ('''4226222172004'',''4212012182004''') I again the number of parameters will very.
Thanks

I am using typed data sets. When a certain line of C# code is reached, I get the following error message:
Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints.
Here is my source code. I altered the table to remove all contraints and primary keys, but I still get the error message. The erroroccurs when the last line of code is reached. (_DeltaTable = myAdaptor.GetData();) The code is listed below. Does anyone know whatis going on?
calculateValuesAndAveragesTableAdapters.FundamentalsTableAdapter myAdaptor = new calculateValuesAndAveragesTableAdapters.FundamentalsTableAdapter();
calculateValuesAndAverages.FundamentalsDataTable _DeltaTable; _DeltaTable = myAdaptor.GetData(); // Error occurs on this line

I dragged two tables into the dataset designer. And I have a query with a resultset over both of the tables (joined).Is there ANY way I can have a strongly typed datatable out of the resultset?The automatically created dataset adapters won't allow me to create a tableadapter or datatable for the joined resultset but for one single table at a time only.Any solution to that? Theoretically it should be possible since I don't "lose" any type information with a join.. why can't I have a strongly typed datatable over the resultset?The join is not very sophisticated. In fact it couldn't be any more simple.(I'm refering to my previously posted question at http://forums.asp.net/t/1220481.aspx)

I have a strongly-typed that I fill w/in my app, then use the dataset to insert rows into a SQL table.
3 fields look like this:
RegHrs - decimal
OTHrs - decimal
TotHrs - decimal
When I insert the fields using parameters, the params look like this:
paramValues(10) = New SqlParameter("@RegHrs", SqlDbType.Decimal)
paramValues(11) = New SqlParameter("@OTHrs", SqlDbType.Decimal)
paramValues(12) = New SqlParameter("@TotHrs", SqlDbType.Decimal)
The fields in the SQL table are defined as:
RegHrs - decimal (9,2)
OTHrs - decimal (9,2)
TotHrs - decimal (9,2)
Before I insert the row (from w/in the VB code), I stop the code and verify that the values being placed into the params are:
5.85
0
5.85
After the SQL insertion, the values w/in the SQL Table contain:
6
0
6
What am I missing?????
Thanx

I'm looking to serialize some NVP data into an XML blob. I plan to put a primary xml index on the column, but my question is, would putting an XSD on the column speed up any queries, or would it just ensure format? I know that with selective xml indices, you can do things like specify the datatype associated with the xpath which can further optimize retrieval.

Has anyone worked out how to trace SOAP/HTTP Endpoints in SQL 2005 SP 2?
I'm not having a particular problem, just want to know how things work, such as which layer is responsible for the HTTP Authentication. I've traced the HTTP.sys stack using logman.exe (see http://www.thelastpickle.com/2008/03/22/tracing-sql-soap-endpoints-through-httpsys/) .
I cannot see any SQL Profiler events, and I've tried setting trace 7801 and 7803 as described in http://www.sqljunkies.com/Article/5CCAC423-1407-4A36-AF71-ED6A67D9646A.scuk#_Toc52964195 but they do not result in any logging.

We have been having a problem with service broker for quite a while now and searching on these forums and more generally on the web has not yielded any kind of answer...
Our application utilises service broker within a single database (there is no cross database, cross instance or cross server communication). There are approximately 12 queues which are used to varying degrees. A few of the queues have a throughput rate in the order of up to 100s per minute at peak periods.
In some scenarios we are able to make use of persistent conversations but the majority of messages are sent on their own conversation or in small batches on their own conversation.
Some time ago we found that the database was growing in size more than expected due to a build up of data in the service broker meta data internal tables, exposed via the sys.conversation_endpoints system view.
We identified a problem in the application that was preventing some conversations from being closed and have now fixed this.
However, we are still experiencing a build up in the service broker tables and sys.conversation_endpoints shows this is now due to a very large number of conversations in the "CLOSED" state.
I know that conversations are kept around to prevent replay attacks but thought they were supposed to be cleared after about 30 minutes. This is certainly not happening as we currently have conversations that were opened on the 18th September, a full week ago. We currently have about 350,000 closed conversations and this figure is increasing!
We have tried restarting the SQL Server instance with no effect.
I have been using a script to loop through all closed conversations and get rid of them using the "WITH CLEANUP" clause but I'm loath to create a scheduled task that does this in the background when service broker should be doing the job itself.
Has anybody experience this problem and, even better, have any idea how to solve it?

Hi, I am trying to use a typed dataset created using the Query builder which returns the data correctly when I use 'Execute Query' in query builder but as soon as I attempt to return a dataset using the GetData method created I get the following error: Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints. Which is not very helpful, any ideas where the problem may be? I have tried switching off enforce constraints and setting the NullValue property of all strings to 'Emtpy' bu that has no effect. Thanks in advance

Hello,I'm using a typed dataset to access my database (SQL Express); I have a table that returns data, which two fields are null; I'm getting this error:{"Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints."}There are no foreign-key or unique key constraints, so it has to be a non-null issue; I changed the two fields in the table to have a null value of Empty instead of Throw Exception, but I don't understand what the problem is coming from... I'm at a loss.Thanks.

Hi,
I have a little question. I searched google, and could not find good answer for this one.
I have a stored procedure that returns two tables. Usually I generate a dataset out of a stored procedure by dragging it to the dataset.
When I drag this one it creates a DS with only one table, the first one. How can I make it use both tables?
Thank you.

However, if I use a typed xml variable that is based on above schema, I cannot use OPENXML. What is the correct way of achieving same result with a typed xml doc? I am using SS2K5.

Hi,
I implemented the pattern suggested in the 'Recycling Conversations' article that Remus Resanu presented. Everything works great except ended conversations on the receiver remain in the sys.conversation_endpoints table forever in the 'CLOSED' state.
Is there some setting I am missing to have those conversations purged from the endpoints table. I am concerned that in the production environment this table will grow very large.
Thanks

Hello,
Using VS 2008 Beta 2, SQL CE 3.5, on desktop, and Typed Datasets: The INSERT command of dataset table adapter does not return the updated identity of inserted row. Why?
also every time I want to modify the insert command to return the updated identity of inserted row, i get the error: "Unable to parse query text."
(Should I post this in Orcas forum?!)
Regards,
Parham.

I'm at loss how I'm supposed to work with typed datasets and Sql Server Compact 3.5, when inserting records and I need to update my datatables with the primary key of newly inserted rows.
I've tried adding a RowUpdated handler to all tableadapters that look like this:
Code Snippet
void Adapter_RowUpdated(object sender, System.Data.SqlServerCe.SqlCeRowUpdatedEventArgs e) {
if(e.Status == UpdateStatus.Continue && e.StatementType == StatementType.Insert) {
if(e.Row.Table.PrimaryKey.Length > 0) {
SqlCeCommand selectIdentityCommand = new SqlCeCommand("SELECT @@IDENTITY",e.Command.Connection);
if(e.Command.Connection.State == ConnectionState.Open) {
e.Row[e.Row.Table.PrimaryKey[0].Ordinal] = (int)selectIdentityCommand.ExecuteScalar();
}
}
}
I've previously used this type of approach when working with an OleDbDatabase, which works just fine. But it doesn't work with Sql Server CE 3.5, and since it doesn't support stored procedures I can't fix it that way either. And it doesn't support commands in a batch (i.e appending the Insert command of the adapter with ";SELECT @@IDENTITY") so that doesn't work either...
So how are we supposed to use Sql Server CE 3.5? It's impossible together with datasets? Or am I missing something obvious?
Any hints would be greatly appreciated! Thanks!
Cheers!

All -
I have a SQL Server 2005 HTTP endpoint. I create a transaction scope in a client application and call two methods on that endpoint. Will the operations performed in the two methods, really, be in a transaction?
In other words, will SQL Server enlist in the ambient transaction even when I am accessing it through a HTTP endpoint?
Thanks.
