SQL Server :: Assign Result Of Count Stored Procedure To C# Variable?
Aug 7, 2010
I have an aggregate stored procedure (named sp2) that returns a count of records meeting a certain criteria ASrecCount. I am using a DAL per the ASP.NET tutorial and have created a Table Adapter (named
sp2TableAdapter) with GetData and Fill methods. I have a button on an ASP.NET page that launches an event handler. In the button's event handler, I have this line: sp2TableAdapter sp2 = new sp2TableAdapter();
What works so far:
This code will bind the value of sp2 to a data control:
When running this page and clicking the button, the numeric value of recCount returned from sp2 is bound to the DropDownList control and 1 row is poplated with the recCount value (in my case 1451).
Problem:
In the event handler, I do not want to bind the value of recCount to a control, but want to to use it in some logic as an integer. What is the C# code that will do this? (In place of the DropDownList control lines above)
DECLARE @nome_soc_repl VARCHAR(50) set @PERC = '(select round((' + @nome_soc_repl + ' /(select sum ('+ @nome_soc_repl+ ') from exptot_perc))*100,2) from exptot_perc)' EXEC (@PERC) nome_soc_repl is a varible that contains my table name
so I need to extrac the result of EXEC...for examples 15...... and put it on another variable.....
I don't know what variable should be put in where clause for tblVisitor.visitorID because there's a variable that was already passed by an output identity parameter by a different stored procedure. What will I put in the where clause for visitor id?
I want to send an image to a stored procedure variable that is varbinary(max) field, It works correctly when an image selected by fileupload and my image property has image file, and it can send to stored procedure. but when fileupload is empty I want to send NULL to stored procedure variable that is varbinary(max). I use DbNull.Value in C# code. But error occurs. What should I do for send Null to stored procedure?
If I have the inventory class and want to make it to be xml and passed to web services and then web services will call stored procedure with xml as input parameters.
I have a SQL stored procedure on a SQL server that uses a variable to create a new database. This works in SQL I have a connection string that works I have added a sqldatasource to a webform, and configured the datasource to connect to the remote SQL database and am able to select my stored procedure. I am able to bind the variable to a control in the sqldatasource wizard (often two of the same control appear- if that is significant)
When I test the sqldatasource in the configuration wizard and put in a manual entry, the procedure runs and works
It is on the web page I am having troubles. I want the user to enter a name in a text box, click a button/link, and run the procedure. Ive used buttons and links...but not in the right way I think, becuase when I click them the stored procedure doesnt run.
As mentioned above, I have selected the right control in the sqldatasource wizard. So what do I need to do now?
Stored procedure ALTER proc [dbo].[spSearchCombo](@searchBy nvarchar(50),@searchKey nvarchar(50)) as select * from CD_DETAILS where @searchBy like '%' +@searchKey+ '%' I'm using ASP.net2.0 with c# to extract rows basedon search key from a text box and searchBy for the column to be searched. When i use column name instead of @searchBy which comes from value selected from a ddropdownlist i get the desired result . There seems to be a problem with format of @searchBy and i get a blank page.
I have a several count stored procedures that are binding to gridview nicely for individual items. I now want a ful count of row so I use a stored procedure with:
[Code]....
Which works fine when testing in the DB and returns results like it should. My problem is that for the life me I cannot work how to display the results to a Label.Text or how to do it when my calendar has posted back thats where @LogDate comes from).
I have a MVC project that has a Linq to SQL dbml class. It is a table called Clients that houses client information. I can easily get the information to display in a View using the code I followed in Nerd Dinner but I have added a stored procedure to the dbml and it's result set is of IQueryable, not IQueryable. I need to convert IQueryable to IQueryable so I can display it in the same View. The reason for the sproc is so I can pass a search string tothe sproc and return the same information as a full list but filtered on the search. I know I can use Linq to filter the whole list but I don't want the whole list so I am using the sproc.
Here is the code in my ClientRepository with a comment where I need to convert. What code goes in the commented spot.
public IQueryable<Client> SelectClientsBySearch(String search) { IQueryable<SelectClientsBySearchResult> spClientList = (from p in db.SelectClientsBySearch(search) select p).AsQueryable(); //what is the code to convert IQueryable<SelectClientsBySearchResult> to IQueryable<Client> return clientList; }
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?

I am trying to return single string result through a stored procedure and Linq. This works fine when I test the stored procedure but it is not returning the value to the page. The value returned is always 0 which is the return value. This is the stored procedure:
ALTER PROCEDURE Login @CustomerName nvarchar(50), @Password nvarchar(50) output As Select @Password=Password From Customers Where Customers.CustomerName=@CustomerName
This is the vb ALTER PROCEDURE Login @CustomerName nvarchar(50), @Password nvarchar(50) output As Select @Password=Password From Customers Where Customers.CustomerName=@CustomerName is the code created by the designer
This is the designer function <FunctionAttribute(Name:="dbo.Login")> _ Public Function Login(<Parameter(Name:="CustomerName", DbType:="NVarChar(50)")> ByVal customerName
As String, <Parameter(Name:="Password", DbType:="NVarChar(50)")> ByRef password As String) As IntegerDim result As IExecuteResult = Me.ExecuteMethodCall(Me, CType(MethodInfo.GetCurrentMethod,MethodInfo), customerName, password) password = CType(result.GetParameterValue(1),String) End Function
