How To Pass Parameters To Stored Procedure
Jun 26, 2011
This 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.
Private Sub btnWithParameters2_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles btnWithParameters2.Click
Dim cnn As SqlClient.SqlConnection = _
New SqlClient.SqlConnection("Data Source=SKYROCKET;" & _
"Initial Catalog=Northwind;Integrated Security=SSPI")

I 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.

I am still quite new to different ways to connect to different in the SQL and Access, i am trying to connect to a StoredProcedure in SQL and pass parameters to append to it. There is a similar program already been built for us which does a similar thing but it is done in VB6 and i am trying to upgrade everything to .NET and this will be the last bit.Here is a snippet of the VB6 as there are a lot of Parameters that need to be passed but once i know how to add a couple it'll be the same for the rest:

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?

1. A dataset contaning all the tables, views and stored procedures from a db in the Data Sources
2. A stored procedure that makes a query using a parameter
3. 2 comboboxes with their DataSources defined
The first combobox gets populated with a stored procedure (with no params, through the Combobox task). When the user selects an item from this combobox this should trigger an event that populates the second combobox with the second stored procedure that requires a parameter.
Since the Dataset is already add to the Data Sources and contains all the procedures I need, I don't wanna to create more datasets or calls to the data base, however I don't know how to set the query using the procedure I already have passing the parameter.

My 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.

I have a stored procedure that takes in 2 parameters and returns an integer value. I would like this value to be the value for a gauge chart on the page. The 2 parameters will change depending on the attributes of the selected item. Is there a simple way to pass the one value from the stored procedure to the chart to display? This will be embedded in an asp.net application (vb) - so depending on the previously selected item, the values for the parameters and result will change.

I have a stored procedure to update a table, but needs a couple of values from another table.
the first two selects get the value from the table and then are used in the update statement.
The select statments:
Select @iStatusDropDownValueID = iDropDownValueID
From DropDownValue
Inner Join DropDownValueType On DropDownValue.iDropDownValueTypeID =
[Code].....
First, the values that are retrieved by the first two select statements are always the same. So they could be passed in by the code itself. I don't know that this will speed things up at all, just make the entire stored procedure better and easier to read.
Second, if the "Value Name" should change this store procedure will break (which is possible, but not often).
I am looking for any insight into the Best Practices for this situation.
