Linq and stored procedure - cannot get results

Posted By:      Posted Date: October 11, 2010    Points: 0   Category :ASP.Net

Hi to all,

i try call a stored procedure from my linq code in order to validate a user credentials. I have tried via linq to sql and sql commands and everything works as expected. But when comes to calling a stored procedure via linq, i cannot get the results i expect.

This is my code:

stored procedure:

ALTER PROCEDURE [dbo].[ValidateUser] (@UserName varchar(50), @UserCode varchar(4))

	SELECT ISNULL(FirstName, ''), ISNULL(LastName, '')
	FROM Users
	WHERE (UserName =@UserName AND UserCode=@UserCode)


                dbContext = new MyDBDataContext();
                var result = dbContext.ValidateUser("Jim", "1234");

                if(result != null)
                    //true, so user is validated so set response status to OK
                    response.Status = ResponseStatus.OK;

                    //set returned params to response
                    var paramsReturned = result.FirstOrDefault();

                    response.FirstName = paramsReturned.Column1;
                    response.LastName = paramsReturned.Column2;
                    //false, so set respone to the corresponding error

No Return Type for a Stored Procedure in a Linq to SQL Data Layer

Hello. First, I don't know if this is the right forum section to post this in, but I couldn't fine a more suitable one. Feel free to move this if it's totally worng. I have a weird problem when using LINQ to SQL and Store Procedures with a return value... The problem is that when I drag my SP's onto the "Methods Pane" the property field "Return Type" is set to (None) and greyed out. And here's the most weird thing... I created a test SP yesterday wich returned SCOPE_IDENTITY() and it worked flawlessly. Dragged it onto the "Methods Pane", could play with the return type property (hence it was not greyed out) and everything was working out nice. I used a ISingleResult<T> and could fetch the .ReturnValue... Today I was going to contiune to create the rest of the SP's i needed with a return type but today when I drag my Store Procedures to my Methods Pane, I couldn't access the Return Type property... I even dragged the SAME procedure I used yesterday (wich then worked great) and now I can't get the dbml-layer to notice that there is a return value... I've tried to create new solutions, new Data Layers, used different databases/servers, but still the same problem... Don't really know if it's LINQ or something else that's causing this... This is how part of my SP wich I used yesterday to test looks

Two results from two different tables by Stored Procedure and put them in variables and send email.


Hi All, first i had like 7-8 steps just to execute stored proc and send email. now i have put everything in one stored proc as follows :

Alter procedure PlanFinder.InsertInvalidRecords

Truncate table [PlanFinder].[InvalidAwps] 
INSERT INTO [PlanFinder].[InvalidAwps](Ndc, AwpUnitCost) 

SELECT DISTINCT P.Ndc Ndc, A.Price AwpUnitCost 
    PlanFinder.PlanFinder.HpmsFormulary P 
    LEFT JOIN (SELECT Ndc, Price FROM MHSQL01D.Drug.FdbPricing.vNdcPrices  
               WHERE PriceTypeCode = '01' AND CurrentFlag = 1) A 
ON P.Ndc = A.Ndc  
WHERE (A.Ndc IS NULL OR A.Price <= 0 OR A.Price IS NULL)

Stored procedure returns two select results


Hey guys

What I would like is to append the column to my original result so I can access it from some vb script using the sqlclient.datareader


INSERT the Results of a Stored Procedure with Multiple SELECT Statements into Multiple Tables?

I have a stored procedure (which is overly complex and written by someone else) that I need to take the results of and put them into tables.  The stored procedure uses Dynamic SQL to build and then run 5 SELECT statements based on literally hundreds of variables.  I need to take the results of these SELECT statements and put them into tables in a different database.  Rewriting or re-creating the logic of the stored procedure is NOT AN OPTION as the logic may change over time and maintaining it in multiple places would be nightmarish.  Can anybody help me with this?  I've googled extensively, but have only been able to find examples of using one result set not multiple ones.

linq stored procedure


Hello there,

I've got a stored procedure which is accesed with linq and it works fine until I add a new parameter to the stored procedure,

initially there are 4 parameters

Exception throws I haven`t supplied data for the parameter

before answer mind that

  • of course I compile when I change the stored procedure
  • I add the value to linq sentence, and you can see when using breakpoints
  • intellisense detects the parameters in the modified procedure
  • stored procedure works fine in SQL Mgmt Studio
  • if I roll back and leave it with 4 parameters or switch parameters works fine

I really don't have a clue.

Thanks in advance

dropdown list fill with Linq and convert string to datetime and ordering and stored procedure call.


I wanted to share this more than anything,  it took me most of the morning searching and finding various post on various sites but I got it figured out and working.  It might be better coded, but it is a start for some one trying to understand how linq and ASP.Net things work.

What I have is a database table with a datetime in string format and a stored procedure which returns all the data.
What I want to do is load a dropdown list with MonthName and Year for a selection choice on generating monthly report.

The stored procedure is in a Linq to SQL class dbml and the connection string is dynamic, i.e., made througha call to another class.

here is the code.  Enjoy understanding how it works.

Send Email from SQL Server Express Using a CLR Stored Procedure

One of the nice things about SQL Server is the ability to send email using T-SQL. The downside is that this functionality does not exist in SQL Server Express. In this tip I will show you how to build a basic CLR stored procedure to send email messages from SQL Server Express, although this same technique could be used for any version of SQL Server.

If you have not yet built a CLR stored procedure, please refer to this tip for what needs to be done for the initial setup.

Inserting rows via stored procedure and under certain conditions


I'm using Dynamic Data with Entity Framework in VS2010.

Let's say my table has these fields:

PersonID (FK)
LocationID (FK)

Hypothetical scenario (it's easier for me to explain this way, so just bear with me for now)... But let's say each row in the table represents "how many items were sold by such-and-such employee at such-and-such location," where location and person are foreign keys which are referencing other tables.  Basically, there should be no more than a ONE row which has a particular combination of Person and Location.  Makes sense?

So, when inserting new rows using my Dynamic Data app, the insert form displays editable fields for Person (dropdown), Location (dropdown), and Items Sold (textbox).  How do I prevent users from inserting another row into the table containing an already-existing combination of Person and Location?   How do I displaying useful feedback to them in the event that they DO attempt to do this?

I have several thoughts about this, but since I'm new to Dynamic Data, I'm not sure which way to go.  For example:

Option 1:  Use "cascading dropdowns" approach in the insert form and only pull in the "allowed" combinations of the two dropd

Need Syntax To Make Results of LINQ Union Return Non-Generic Type



I have the below SQL which works just fine:

SELECT     Message, CreateDate, AccountId, AlertTypeId
FROM       dbo.Alerts
SELECT     TOP (100) PERCENT Status, CreateDate, AccountId,
                          (SELECT     10 AS Expr1) AS AlertTypeId
FROM         dbo.StatusUpdates
WHERE AccountId = PassedInParameter

I have been going about trying to convert the above into a LINQ method and am having problems with return types.
As the above SQL illustrates, I am querying two distinct LINQ tables - Alerts and StatusUpdates -
and then attempting to perform a Union on them. In order to do the union in LINQ, I have to have agreeing types. So, I
am using "var" to make the results of "alerts" and "updates" generic before the union.  

public IList GetStatusUpdatesAsAlertsByAccountId<T>(Int32 accountId)
            using (WorkbookDataContext dc = _conn.GetCont

I just tried with "execute immediate", which would throws error as 

"insufficient privileges".

Please help me.



Test Run: Testing SQL Stored Procedures Using LINQ


Language Integrated Query makes lots of things easier. Here we put LINQ, or more specifically the LINQ to SQL provider, to use testing SQL stored procedures.
