SQL Server :: Declaring Variable In Stored Procedure?
Feb 16, 2011
I have this procedure
[Code]....
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?
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)
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 created stored procedure and student database and also asp.net application for asp.net page but it could not found stored procedure what is the mistake actually I don't no
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 !
using (SqlDataReader sqlDataReader = ExecuteReader(CommandType.StoredProcedure, StoredProcedures.AuthenticateUser, sqlParameter)) { isAuthenticated = Convert.ToBoolean(sqlParameter[2].Value); if (isAuthenticated) { if (sqlDataReader.Read()) { User = new UserEntity(); DbHelper.GetEntity(sqlDataReader, User); } } }
I always get isAuthenticated as false because sqlParameter[2].Value is null all the time but when I execute my query with ExecuteNonQuery it gives me the value but in that case I can not fill the entity.
I've written a stored procedure which uses a table variable. The stored procedure is shown below:
[Code]....
The table variable @CaseNumbers is declared, and is a bunch of values are inserted using a table-valued function called SplitStringIntoInts. At this point I can select from @CaseNumbers and this works fine.But when I try to join onto @CaseNumbers, the name '@CaseNumbers' in the ON clause is highlighted with the error 'Must declare scalar variable @CaseNumbers'. What?! It's not scalar, I declared it ages ago and I have used it since!
Is it possible to save execute stored proc command in a string variable and then execute string variable? Does this logic fits into LINQ2SQL? Why I want to do this - INstead of passing user control references to server, I want to save user control values to string in client side java script and then pass string to server to do actual stored proc execution. Hopefully this will improve performance.
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.....
Here's a stored procedure I created that uses another stored procedure inside it to return a value:
[Code]....
Note the 'exec dirinfo.dbo.d_searchempbyname @TicketSubName' part. That stored procedure will return a single record. What I need is to get a single column from that recordset (in this case, the email address of the employee), and store that value in a variable.
I am trying to create the following stored procedure in sql server Lat and Lng are the parameters being passed from c# code behind .But I am not able to create this stored procedureit indicates with error saying undefined column name Lat,Lng
CREATE FUNCTION spherical_distance(@a float, @b float, @c float) RETURNS float AS BEGIN RETURN ( 6371 * ACOS( COS( (@a/@b) ) * COS( (Lat/@b) ) * COS( ( Lng/@b ) - (@c/@b) ) + SIN( @a/@b ) * SIN( Lat/@b ) ) ) END sqlda.SelectCommand.CommandText = "select *, spherical_distance( Lat, 57.2958, Lng) as distance from business [code]...
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?
I have a really simple web interface which has been created in visual studio 2010 and is connected to an SQL server running MS SQL Server 2008. I essentially want the user to be able to enter values into the two text boxes provided and when the button is clicked, these values are inserted into the relevant table in the database.
When I run the code, I get an error back saying that the 'scalar variable for @clientName is not defined.' I have altered the insert statement to fixed values rather than entering from the text boxes and this works fine (ie, replace @clientName and @serverName in the insert statement with 'xx' and 'yy' respectively). How I can define these scalar variables. I'm not to sure what i'm missing. Code below.

The code that the button executes is below
Partial Class Default2 Inherits System.Web.UI.Page Protected Sub Button1_Click(sender As Object, e As System.EventArgs) Handles Button1.Click SqlDataSource1.Insert() End Sub End Class
I want to declare a Dictionary<string, object> variable but don't know where/how to. The values in the dictionary will be objects from the Page (ListBoxes, DropDownLists, etc) so I can't exactly create a class somewhere else. Is there any way I can make this variable accessible from each method in the codebehind?
