SQL Server :: Send NULL Value To A Stored Procedure Variable?
Sep 26, 2010
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?
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'm strugling with this problem for quite some time and I've tried many different solution but nothing works. In my application there are 3 textboxes. First is mandatory but user can leave second and third empty. I that case I want that application insert NULL.
Here is .aspx code:
[Code]....
c# code:
[Code]....
Stored procedure:
[Code]....
I've tested code when user fills all 3 textboxes and it's working fine. If one second or third (or both) textbox(es) is(are) empty I wish to insert NULL into table. I've tried with DbNull.Value, null, 0, "3232131" and nothing works. I always get error Input string was not in a correct format. which is strange since code works when 2. and 3. tbs are filled and I'm not inserting string. And I've specified that table allows inserting of null values.
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)
set ANSI_NULLS ON set QUOTED_IDENTIFIER ON go Create PROCEDURE [dbo].[sp_GetNextSeq] ( @p_NextSeqNo int = NULL OUTPUT ) AS BEGIN SET NOCOUNT ON; BEGIN TRY BEGIN TRANSACTION Generate Next Sequence Number [code]...
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 am using SqlHelper.ExecuteDataset(MyConnectionString, CommandType.StoredProcedure, "GetInformation", new SqlParameter("@ID", ID));
In my stored Procedure, I am doing a lot of calculation with joins and it took 19 sec to execute at my sql Server 2008. My application had been working perfectly for 5 days but now as database increases, I found a problem that my connection is breaking at that point. At Sql Server, it execute fine but when I add a breakpoint and watch the stored procedure is returning null.
I am creating a nightly process using a stored procedure to check for expiring records and emailing myself and the folks that need to see the information. The trouble I am having is trying to send the data in table "like" view in the message body.Here is the Proc you can see the point at which i try to use a table vairble then use it as a parameter for calling the email proc but it doesn't seem to work.
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
i have a stored procedure to update a table. not all fields are required and some can be blank.for example, title is not required, but when it's blank i get an error
Dim ptitle As New SqlParameter("@title", SqlDbType.NVarChar, 20) ptitle.Value = objFormat.CheckSQL(title) myCommand.Parameters.Add(ptitle) ex {"Procedure or Function 'sp_UpdateUser' expects parameter '@title', which was not supplied."} System.Exception
how can i fix it so that it allows for nulls if the data field is blank?
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!
I am using this stored procedure with pivot.If i dont have data i am getting null with this stored procedure.Can u tell me how to handle null.below query is pivot.
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.....
We have an ASP.NET web service that invokes a stored procedure on our DB (Oracle 11g). The problem is that the call to the procedure blows up every time an empty string is passed as one of the parameters. We're seeing an ORA-01084 error, which indicates to me that call is failing before the procedure is actually run.
Here's the procedure, minus some logic that I believe is not relevant:
[Code]....
As an experiment, I modified the web service to pass null rather than an empty strings. When null is passed in, I see an error indicating "wrong number or types of arguments in call to 'CREATEREPORT."
I also tried passing DBNull.Value whenever the params were null/empty, but that resulted in the error
Parameter 'p_column_id': No size set for variable length data type: String.
(Of course, p_column_id was the empty parameter in this case).
So, how can I successfully pass empty strings as parameters to my stored procedure? We definitely want to allow the p_column_id parameter to be empty.
