View 2 RepliesSo I just attempted to call a stored procedure from my VB code. Here is the code-behind function that is called to handle this:
[Code]....
And here is the Stored Procedure:

Then when I run this, I get an error that the server timed out. Without calling this function to reference the stored procedure, the application runs well, users can log in/create accounts, etc. But something in the function and/or the stored procedure is timing out.
I have a req in which I have to call an AS400 stored procedure.The stored has an input and output parameter.

I am trying to re-write an existing asp.net website using MVC with Linq to SQL. A page we have is used to insert new contracts and uses usp_contract_insert to insert a new contract into t_contract as well as t_project.

One or more selected database objects return a schema that does not match the schema of the target data class. Nothing has been added to the designer. The stored procedure returns the id of the last project which was inserted.

View 4 RepliesUsing asp.net MVC in c#, I am making a call to a stored procedure using Linq into my SQL Members table. I have no internal caching on the application, already checked to make sure it is turned off.
Test case:I have my username set to test1. From the website I change my username to test2. The website still shows test1. I go to Management Studio and run my stored procedure called MemberByEmail, it shows test2 correctly.I start simple, refresh my page to see if it's browser cache, still test1. I go to debugging and walk through the code and find that it goes correctly all the way to here to call the database:
/// <summary>Method that is mapped to the dbo.MemberByEmail database procedure.</summary>
/// <returns></returns>
[System.Data.Linq.Mapping.Function(Name="dbo.MemberByEmail")][code]...
Again I ran the stored procedure through Management Studio, and it came up with test2 as the username. I waited for 15 minutes, refreshing the web page every 5 or so, and it never cleared and served the correct test2 from the db. The last strange piece, I ran IISReset and refreshed the page, test2 was returned.
UPDATE: I created a console application to take out the web piece of it. The problem is the same when accessing directly from a console app also, no change.
