ADO.NET :: Using Stored Procedure After Select Statment Give The Old Results?
Mar 12, 2011
When Select an entity by linq with entity framework 3.5 ...and thenn select it again using stored procedure ..which change the value for a field for that entity ... i got that with old value ...not procedure value...............When i called that procedure before .. the select ... i got the correct value.........but in my case i shall call the procedure after select with linq statment
how can I create stored procedure and write my select statement in it, I know how to create dataset then put type stored procedure and assign it to the sp ... what I want is writing my sp... how can I make it ?
check the following code, this is what I want to write put I don't know where or how !
If the from date is given then i have to retreive all the values above from date .IF to date is given have to retrieve all the values below Todate.else between from and to date how it will make changes
I have a windows aspx form that I have a TextBox, Button and a GridView. The TextBox is stored as a variable @subschedule and passed to a stored procedure. What I'd like to do is to populate the results of that procedure into my GridView.
It seems like this would be fairly straight forward. I've got a gridview that loads up using one stored proc, but I've got a searchbox to filter the grid, and when the user enters some criteria I want to use a different proc to return the results. Something tells me I should be doing this with one procedure, but I can't seem to make that work either. When the form loads, my grid is populated. And if I leave my search criteria blank and search anyway, my grid is still populated correctly. But if I enter search creteria, I get diddley squat. What gives? Here is the relevent snippets.
I am trying to get the results of the variables from a stored procedure to write out somewhere so I can see what values are being passed through for each variable in a button click. Does anyone know how to do that. Here is my code for the button click:

Here is my variables in the stored procedure. The first is the select statement and then the update:

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.
My code currently correctly obtains their ID, adds it as a parameter to my stored procedure and executes the procedure;
[code]....
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:
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.
I tried nested ListViews but can get the display wanted.In my database I have a Category Table and a Product table.They share the CG_ID value.I want to make a stored procedure that will use two select statements to produce a single table.that can be used as a ListView DataSource.
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.
I have created the tables and the stored procedures in SQL 2008.
In VS 2008, I created DataSet1.xsd in App_Code and created the connectionString in web.config file.
Then when I go into the DataSet1.xsd and try to add a TableAdapter, strange things happened.
First I chose the data connection, then selected "Use existing stored procedure", then there was nothing listed in the dropdownlists (in Select, Insert, Update, or Delete).
I'm sure the connectionString is correct because if I choose "Use SQL statement" and type in a "select * from mytable1", the TableAdapter can be created without any problem.
