But when I run the stored procedure on the sql server it works fine and return records, I just don't get it... What is wrong and causing this error?
recently we migrated our website from one server to another. For the most part the site is up except we have a calendar on the site that allows event insertion, when we attempt to add a new event it throws an error of "Sql Exception was unhandled by user code...An explicit value for the identity column in table 'dbo.Events' can only be specified when a column list is used and INDENTITY_INSERT is ON". Now i know about identity columns and know that that is not the problem, because that particular table (Events) has a dependent Stored Procedure associated with it, that is not longer being executed! Unfortunately i inherited this site and am trying to make sense of it all. The error is happening at line "cmd.ExecuteNonQuery()".

Is it possible to add multiple select statements in a single stored procedure. The select statements are getting data from different tables. If yes, could anybody provide an example in adding multiple select statements, which retrieve data from different tables in a stored procedure.
View 3 RepliesWhen can I use Stored Procedure? Is this useful for looping into multiple SELECT statements to return single value? How? Can anyone post some sample codes? I have text query and notice that my web application is slow and want to find ways to speed it up. Is there any possible ways aside from Stored Procedures?

I'm programming a webpage in ASP.NET which displays a list of students not listed as participants in something, and upon clicking a student name shows you a brief summary of their details, so the user can ensure they're selecting the right person.

However, when I try to access the results I get the following error:
System.NullReferenceException: Object reference not set to an instance of an object.
Upon debugging, there don't seem to be any results returned... but when running just the stored procedure in SQL Server with the same data, it does return a single row, as expected.
How do I access this result so I can bind it to my fields?

Ive been banging my head against the wall for the last 2 days with this query I am trying to produce. I have an application that creates requests and these requests have status codes dependant on how far along in the process they are : new request, awaiting approval, approved, in progress, complete When a request is moved to the next status, it Inserts a row into an auditing table, so we can track who moved it onto the next status, along with a timestamp. There are Service Level Agreements in place that mean that a request that is currently 'In Progress' must be actioned to 'Complete' within 5 days. I have been asked to create a query that will return all records that fall outside of this SLA. My main problem is trying to Select the time from the audit log for 'In Progress' and 'Complete' status codes. It would be simple if i only had to find one of the times, as i could add a "WHERE StatusCode = 'complete' clause to the query My Audit table is structured as follows:
[RequestID] [Request Status] [UserID] [CreateDate]
So far I have been successful in querying the table by using the DATEDIFF() function as below:
SELECT
DateDiff
(day,
( SELECT
top 1 CreateDate
FROM audit_tblRequest
WHERE RequestStatus
= 'In Progress'
AND RequestID
=
@RequestID Order
by CreateDate
DESC)
,(SELECT
top 1 CreateDate
FROM audit_tblRequestWHERE RequestStatus
= 90AND RequestID
=@RequestID
Order
by CreateDate
DESC)
)
This will return the difference in days to me, however, i cannot figure out how to integrate this into a query that will be run across all RequestIDs. I was wondering if there was any way to bundle the DateDiff function into a stored Procedure and be able to call it For Each RequestID in the result set I would need to pass the requestID as a parameter, and also add some If Else logic to only return records outside of the 5 Day SLA. Im sure there are some patches in the above logic, but my brain is about to explode and I needed to type it all out before calling it a day for today.
I have a stored procedure that receives 2 parameters and returns 3 columns.
Here is how I added the SP:
1. Added SP to entity model (.edmx) via update model from DB.
2. Did a Function Import -- selected my SP, clicked "Get Column Information" and then created a new complex type (myStoredProcedureName_Result) which I assigned.
3. My LINQ is the following:
