I see this asked many times on hereI'm copying this question that I found on here.Is there any way to pass a null value (I mean a value that the sql will interpret as null) to a stored procedure when using:tableAdapter.Fill(dataSet.table_name, param1 (as string),param2 (as string) etc...Which is the most painless way to do this(assuming that the sp stays inside the database!!)
View 4 RepliesMy application is asp.net with vb. In my page I have a textbox for passing date. If I didn't enter date and on clicking submit, I have to pass null value to the stored procedure. I tried following codes such as DBNull.Value and DateTime.MinValue. In that case instead of null ,"#12:00:00#" is passing. I have to pass Null.

The field I need to make NULL is a DateTime field
DB.Parameters.AddWithValue("@date", NULL)
This gives me the error 'NULL' is not declared. 'Null' constant is no longer supported; use 'System.DBNull' instead

View 5 Repliesi 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?

View 4 RepliesI'm reading "Programming with Microsoft Visual Basic 2008". At the end of each chapter there is excersize that I don't have the answers sheet for. Anyway, the first one is:

In a VB.NET, I code to exec a store procedre (sp_truncate) to truncate 10 tables and using sqlBulkCopy to download a huge data. Both them are working fine. Now I want to use transaction with vb.net (not in store procedure?) to rollback truncate tables if download is failed. Is it possible to use transaction to work with these two steps?

View 1 RepliesThis code calls a store procedure that takes input parameters. With this code I'm confused as to how the parameters are passed to the stored procedure. The parameters are first stored into 2 string variables (strCategoryName & strOrderYear). They are then copied/moved to an sql parameter prm.value. But the stored is stored in an sqlcommand (cmd ). I can't understand how the stored procedures knows what the parameter values are.

If I send a String set to Nothing as an input parameter to a SQL stored procedure, and in the sproc it's like this @MyString Char(9) = NULL, what does it turn NULL into? Because I'm firing the sproc and it's not firing the statement that says IF @MyString = NULL... So I don't know what it is... Or how can I pass the string as a NULL if nothing is passed as a parameter to my calling function?
View 4 RepliesI am building a three tierd app, and therefore have all my data access methods in a class by itself.This class only calls stored procedures, basically, I need to pass in the following:
1) stored procedure name as string
2) parameters as IDataParameter() -- an array of parameters
3) other fields ( not important to this discussion)
If I use a GridView on my web form and choose an ObjectDataSourceObjectDataSource, and then choose my business object and method, since the method is a call to a stored procedure with a parameter array, I don't know how to pass it values in the IDataParameter format.The Method Signature listed on the wizard is "RunSP(String spname, IDataParameter[] params), returns SqlDataReader" which basically is calling a method called RunSP with two parameters, of which the second parameter is a parameter array for a stored proc.
I have created a database with on table that is very similar in setup to ProductCostHistory from the Adventureworks database. Using the adventureworks database as an example, when the procedure is given the parameters of date and productID it will change the EndDate of the currently active cost to the date value and insert a new record with productID as the ProductID and Date as the StartDate, leaving EndDate null for the newly inserted record. I am looking for a way to create a simple form with two textboxes and a button. textbox1 accepts the ProductID parameter and textbox2 accepts the Date value. when the button is pressed, the stored procedure is executed and the table is updated. This seems pretty simple and I am very familiar with tieing stored procedures to a table in a dataset when each prcedure handles only a single simple action (either, SELECT, INSERT, UPDATE, or DELETE but not a single procedure that combines UPDATE and INSERT as the procedure described above does). I've done some reading and played with this on myown but can not find the simplest straightforward way of accomplishing this seemingly simple task.

View 1 RepliesI have a stored procedure (SQL Server Express) that returns a count of records:
SELECT COUNT(AdminUserID) AS CountEm
FROM Licenses
WHERE (AdminUserID = @AdminUserID);
Table "Licenses" has a field "CompanyID" which is a uniqueidentifier.
I need to add a clause to the WHERE to exclude records from the count where "CompanyID" is null/empty.
In VB code I'd do this with "If Not (TheCompanyID.Equals(Guid.Empty)) Then"
How would I do this in a stored procedure?

I am having some difficulty with an xPath expression. I am using an XML document to store queries / stored procedure names in an ASP application. I use a utility function to load the xmldocument (if it isn't previously loaded) and I am attempting to select the node set from the document that matches an Id element. [code] the node variable only returns the first element. I have verified the that the qry string that is used to SelectSingleNode IS the correct Id value (i.e. USER002) - however the node is getting loaded with the USER001 element. It is obviously the xPath expression that is messed up. What do I need to tweak on the xPath expression so that I can return the correct <Id> element and corresponding child <Sql> element.
View 2 RepliesI have a table that I need to insert a set of records into based on user input. IE: Selection from a list of items to choose from. For this example, let's just say it's a collection of int's.
Not a lot of good examples on the internet. There's only one related question here on SO, but it lends no answers either (both answers are dead ends).
How do you setup the call into the Package from .NET? How do you setup the Package Procedure or Function to receive the collection? How do you process the collection once inside of the Procedure or Function?
