DataSource Controls :: DBNull Error Trying To Call Stored Proc?
Jan 7, 2011
I have a recordset in a gridview that comes from an outer joint that creates null values in the recordsetWhen I write to the database using stored proc defined in datasource I get dbnull error.I'm trying to process the onDeleting event in the code behind but don't know what to write or if that's the best wayI need to call a stored proc and if the last parameters value is null then the stored proc does one thing, if it's no null it does something else.However DBNull doesn't ssem to be working.
I have made a simple stored proc which include Transaction through which I have to delete records from two tables EmpDetail and EmpDept . EmployeeId is PK in EmpDetail and FK in EmpDept. Procedure has been executed but on doing exec DelEmployee @EmployeeID='e07' showing 0 rows affected..
I've been self teaching SQL and asp.net and i'm a little stuck. I have a stored proc for the insert and then in my Insert inside my class it's not returning the ID after the insert as I am receiving an error message that NULL value has cannot be inserted. I want to add default values to a seperate table after the insert. I will provide my code below, if anyone can help me why the value is not going across?
I have a .net 3.5 page that calls a short sql server procedure which compiles fine. When the code is called
from a webpage(.net) it runs the first time it is executed. However on the second time it throws an error saying "There is already an object named 'strPKHoldUp' in the database." StrPKHold is a variable that I declare in the code as seen below.... I have never had a problem before with declaring a variable and having it "save or cache" in the database so you can use it again. Any idea how to solve this? I tried moving the DECLARE statement around a little bit but that didnt. I changed the variable name to something else and it works one time but fails after that...

i'm a total newbie with asp.net mvc and here's my jam:
i have a 3 level list box which selection on box A shows options on box B and selection on box B will show the options for box C.
I'm trying to do the whole thing in asp.net MVC and what i see is that the nerd dinner tutorial uses the ORM method.
so i created a dbml to the database and drag the stored proc inside. i create a datacontext object but i don't quite know how to connect the result from the stored proce which should be multiple rows of data and make it into a json. so i can keep all the json data inside the html page and using jquery i could make the selection process faster. i don't expect the data inside the three boxes to change so often thus i think this method should be quite viable.
Questions:
So how do i get the stored proc part to return the data as json? i've noticed some tutorial online that the json return result part is at the controller and not at the model end. Why is that? Edit FYI, i find what i mostly wanted to do here. For the json part, i referenced here.
each of them is a check box inside this check box list and i have a stored proc that takes paramter which is the name of the city and gives me a data according to the name of the city (Filter). i wana know if i checkec more that one city how can i pass this to the stored proc eg if i checked on cairo and alex what can i do to make the filter looks like this where city Like 'Cairo' and City Like 'Alex' My Stored Proc takes @City Parameter like this Create Proc xx(@City varchar(2)) how can i pass the 2 cities 2 the stored proc

Initially, I have tried to use stored procedure. But I changed my mind and preferred to call sql query in codebase with command text. However, it stills tries to find initially-called stored procedure (which is neither called or exists).I think that it is related caching. But I tried it with different browsers it did not work.What might be the reason?
Am stuck with this sql stored procedure/asp.net vb.
I want to call the stored procedure and for it to return a true or false if successful ie username and password match.
My stored procedure works fine, and I can call it from my vb, however I stuck as to how I get it to return a result of true or false, 1 , 0. I just get a blank page.
I spent about 60 minutes sifting through search engine listings trying to figure this out and couldn't find an answer, so I decided to make this post for others.
Situation: Using a Stored Procedure to insert a row and return the new row ID, explained here. In my case, I used the Idenity_Scope to return the new row, like so:
[Code]....
Next, following steps as described in link above, went into the dataset XSD page, configured the table adapter to use this stored procedure. By default, it wanted my return value to be set to some value, but I set to allow Null (makes sense, since I don't want to pass the value in, I want to get it out, so it should be null to begin with).
Problem: Where I ran into an issue was in the method to call this stored procedure. The intellisense displayed the prototype it was expecting, basicly like this:
I am trying to do an update and if no selection has been made in a dropdownlist (integer) or date field I would like to insert a dbnull value. But I am new to Linq to Sql and wonder if this is possible and if so how to process. I have the following code but the DBNull.Value is giving me an error.
Dim context As New SondageDataContext() Dim repondant = (From r In context.Repondants Where r.RefRepondant = iRefRepondant Select r).Single repondant.Prenom = strPrenom repondant.Nom = strNom 'dates If dtAdhesion > Date.MinValue Then repondant.DateAdhesion = dtAdhesion else repondant.DateAdhesion = DBNull.Value End If 'Integer for dropdownmenu If iOccupation <> -1 Then repondant.RefOccupation = iOccupation Else repondant.RefOccupation = DBNull.Value End If context.SubmitChanges()
I have a button which the admin will click on every new acad year to update the student's study level.
I have written a SP to do this process, however, it was working fine. But I faced problem when I did testing.
This is my student update study level stored procedure:
UPDATE Student SET acadLevel = (CASE WHEN acadLevel < '3' THEN convert(char,acadLevel + 1) ELSE convert(char,'G') end ) WHERE acadLevel between '1' and '4';
Error: Conversion failed when converting the varchar value 'G' to data type int.
