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;" & _

IDE :: Pass Parameters To Stored Procedure Through ObjectDataSource?

Jun 7, 2007

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.

Pass Parameters To SQL Stored Procedure From Application?

Apr 6, 2009

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.

Asp.net - Return Two Tables From A Stored Procedure From LINQ To SQL?

Aug 4, 2011

I have written a stored procedure like this:

CREATE PROCEDURE [dbo].[TestProcedure]
AS
BEGIN
SELECT TOP 1 CampaignID FROM Campaigns
SELECT TOP 1 ServiceID FROM Services ORDER BY ServiceID desc
END

In my .NET Project, I have a LINQ to SQL file (.dbml) and I have drag-and-dropped this procedure to create a new class TestProcedureResult:

Partial Public Class TestProcedureResult
Private _CampaignID As Integer
Public Sub New()

[Code]....

So it is not returning ServiceID. How can I retreive ServiceID using LINQ to SQL? I know we can customize stored procedure calls, but how can I customize in this particular scenario?

Error 1 Value of type '1-dimensional array of aaaDatabase.stp_GetSomethingResult' cannot be converted to '1-dimensional array of String' because 'aaaDatabase.stp_GetSomethingResult' is not derived from 'String'.

Sql - Getting Parameter For A Stored Procedure Inside Another Stored Procedure

Aug 29, 2011

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.

How Stored Procedure Run

Dec 22, 2011

I have noticed the following but unable to understand why.Whenever a procedure is called in .net it takes more time than when it is called subsequently.Even if a procedure is called after some interval it takes more time than it takes if it is called quite frequently. i am not asking about sql query or sql command. any user definded function or user defined method takes much more time to finish when it is called occasionaly. but when the same procedure is called quite often it finishes a lot faster. why?

Run A SQL Stored Procedure ?

Jan 26, 2012

I am currently building an ASPX webpage for internal use. Basically, there are two buttons on this page and I need each one to kick off a different stored procedure on our local SQLServer based on the needed task. these stored rocedures do quite a bit of work and take 3-5 minutes to finish running. In neither case do I need any kind of gridview or other output from these stored procedures, as they are simply crunching/cleaning data that will populate some tables that the user will then use to complete their task. There are also no inputs or parameters needed.

So i'm OK at ASPX and pretty good at SQL, but have no idea on the VB code behind page. This is what I have ben able to put together based on 3 days of googling. i think i am close but can't quite get across the line.

CODE:

I'm not sure if you need to see any of my ASPX or my SQL. both work fine on their own, but i am not able to get these buttons to work.

ADO.NET Timing Out On Stored Procedure?

Aug 11, 2009

I have a stored procedure that when I run it within my application it times out, but when I use Management Studio and pass in the same exact parameters, the stored procedure executes under a second. I had this exact same issue with the same stored procedure before, and all I did was recompile it, and it fixed the problem, but I do not want to keep having to recompile this stored procedure every few days or so. Has anyone else ran into this issue before?

Another note I would like to mention, is that I'm currently working on a test database, so I'm not inserting, deleting or updating any of the records that the Stored Procedure is using. So the database itself is not changing, but for some reason the Stored Procedure is showing degradation, and at the most we have 2 users in the database at a time.

Below is the code I use to call the Stored Procedure from my app.

cmd.CommandText = "sp__RECAP_SELECTION_GET_GRID_RECORDS_RECAP_TYPES"
cmd.Parameters.Add("@FK_KitchenID", SqlDbType.SmallInt).Value = cmbKitchenCustomer.KitchenID_SelectedPrimaryKey

[Code]....

As I mentioned, if I run the Stored Procedure within Mangement Studio, it runs with no problems. Also if I recompile the stored procedure, it runs fine within the app, but after a few days, the stored procedure starts to timeout again within the app and I need to recompile it again.
