Asp.net - ODP.NET Calling A Stored Procedure And Returning A RefCursor
Mar 27, 2011
This problem has driven me mad for over a day now. I can create a connection to the database, I can execute sql and return results from that but I can't seem to call a stored Procedure. Here is the code
[Code]...
it works ok but no results are returned. I've verified that the procedure returns results for the user I'm logged in as. When the query was executing I could see a refcursor in there but it was empty. I must be going mad.

I am posting this here because the sql query seems to be fine, it is the VB code that is the issue. I am new to VB and I have a subroutine that imports a value for the strating and ending time of a report. The error I am getting is: Conversion failed when converting the varchar value 'Aug 20 2009 12:00PM' to data type int. Here is the code for both VB and SQL:

I am pretty new to VB and I am not sure why this is not working, basically I am trying to run a stored procedure from my web code. The sp runs just fine in SQL, I've tried it several times so I am sure that is not the problem. I don't want to return any results, I just want to see an "ok" statement if it runs and an error message if it doesn't. The code I am using for the lables (warnings and confirmation) is reused from earlier on the same page, the same goes for the validations (valUpload).

(Using MVC4 VB EF4 MSSQL Razor)
I created a Stored Procedure in the MS SQL 2008 database. Then i've added that SP into the Entity Framework model (you do not see it after opening the .edmx file, i see the SP when i open the model browser). Next i did an "Add function import..." . I did [Get Column Information] and "Create new complex type".
So now i'd like to use that SP. And using ExecuteStoreQuery seems the way to go.
The best attemp so far is this:
Function Index() As ViewResult
Dim context As New MyEntities
Dim Result

I'm trying to update a table via a stored procedure from asp.net. I get the following error message: "wrong number or types of arguments in call to 'UPDATE_DIRECT_BILL_DETL_SP'"I just can't seem to figure out what is wrong. I believe I may not be using the correct Oracle variable types in my Cmd.Parameter.Add statements.[code]

STORED PROCEDURE
ALTER Procedure [dbo].[usp_validatecard](
@CLUBCARD1 nvarchar(50),
@STATUS nvarchar(50))[code]....
What I am trying to do is if the clubcard parameter is found and status is active I would like the label to read 'card is good' also if the clubcard parameter is found however is inactive then the label should read 'card is good but not active' last if all those fail just have the label read 'card not in system'As of right now this code does not work I thought I could just call the stored procedure and exec it and it would print the statements depending on what passes however it is erroring out. When I debug it the error I get is under the cmd.parameters.add is
Item In order to evaluate an indexed property, the property must be qualified and the arguments must be explicitly supplied by the user.

I am trying to obtain a value by calling a stored procedure I am trying to use the n tier design as opposed to the wizards. I am not sure how my function should look when it is called from the persistance class. I am using MYSQL for the database.
The persistance class works and the stored procedure works in the database.

When calling a stored procedure from vb.net is there a default SQL timeout time if no timeout is specified in the connection string?I am unsure if there is a CommandTimeout specified in the connection string but am going through all the possibilites.
Example if no results after 30 seconds (or more) throw:
`System.Data.SqlClient.SqlException: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.`SQL Profiler says that the script runs and ends in 30 seconds when the program timesout..Tthe script runs without error in about 1 minute 45 seconds by itself in SQL server.

this is the first time i am calling a stored procedure via vb.net and i would like to make sure i have everything correct before i execute it. This is my code:
[Code]...
The stored procedure returns 6 colums worth of data and i would like to add that data to a listview. I'm not sure i have the correct sytax for doing that but this is what i used in my previous sql code (running a query with, not a stored procedure). Also, i'm not sure how to go about getting data for the @xxx names above from a textbox? How do i pass the values into the @xxx names from the users textbox? The MS SQL mangement studio code is this for the the stored procedure:

I've got a conversion utility that basically copies values from one table to another. It's worked great for a while, but I've run into a strange issue with one customer. They got through 1.5 million records with the utility but now it is completely halted.When calling a stored procedure from VB.Net, it just hangs until the SqlCommand times out.Calling the same sproc from Management Studio executes instantly. My VB.Net code for the SqlCommand is below (insertConn is defined and opened earlier, dr is a SqlDataReader that has been populated in a previous step from completely different SqlConnection and SqlCommand instances):
Dim conn As New SqlConnection("connection string here")
Dim insertConn As New SqlConnection("connection string here")
Dim dr As SqlDataReader = Nothing

I have been creating some asp.net sites that connect to an AS400 for data and I use a SQLDataSource for this with the following connection string (changed for security reasons). Now I need to create a winform application in VB.NET and am wondering how I would do this? I have only used MSSQL in winforms and use the sqldatareader for Select statements and execute non-query for others. I need to call some stored procedures on the AS400 passing parameters. I was hoping to do this by code like I do with MSSQL rather than drop in controls to bind to.
Provider=IBMDASQL.DataSource.1;Data Source=192.168.100.2;Password=xxxxx;User ID=xxxxx;Initial Catalog=S12345;Default Collection=AABBCC

I am developing a Windows application for restoring specific databases from our Production platform to "field" tablets by using backups that are taken daily to disk. To preclude "orphaned users" on the tablets, I want to extract the "user name", "password" (hashed) and "sid".I am calling the MS Stored Procedure "revlogin" that produces screen text to copy and paste into a query to recreate those users on another SQL server instance.
IF (@denylogin = 1)

I have created a search form based on my SQL database to search for individual records based on 3 types of criteria. The form is up and running but I want to be able to add some more code. I have assigned Stored Procedure to each click event for each button. What I wantr to be able to do is after value is added to text box and button is clicked if there are no reults to display than a message box is displayed with adequate message detailing this. Also is it possible to add a count of records to the form. Once value has been enetered ij tyext box and stored procedure runs and fills dataset with required data can I display a box to show number of records from this search.

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.

I'd like to think that I am decent at VB but while I was learning javascript the other day I found something that seemed awesome and now I cant figure out how to do it in VB.in javascript it looks like this
var someValue = getThatValue()Its both calling and setting the value from the getThatValue() sub. what is the VB equivalent?

I am using this vb.net code file to call a procedure to get dates (among other things). When I execute this procedure in SQL 2005 Server Management Studio, I get about 10 columns. However when I execute this code, the dataset seems to only have one index value, maybe I am misunderstanding something. When I change this
ds.Tables(0).Rows.Count.ToString
to
ds.Tables(1).Rows.Count.ToString <---changing the index value to 1
(or higher)
I get no information. So my question is;
Does the DataSet contain the other columns, only not indexed like an array? What I want to do is choose which of the columns to filter out and turn the rest into JSON formatted strings.

I have a MDI app that I am creating. It, of course, will have multiple MDI child forms. In each child form, I have an options button so that each child form can have it's own set of options. When I click the options button it opens an Options form. This options form is not an MDIChild.
I have a class that contains the child forms options. I pass this class to the options form using a constructor. This is how I call the options form:
Dim dlgPatternOptions As dlgOptions = New dlgOptions(thisPatternOptions)
thisPatternOptions is the class that I am passing to the Options Form.
This works fine and the options form does populate the options correctly. The Options form constructor is this:
Public Sub New(ByRef thePatternOptions As CanvasOptions)
Me.InitializeComponent()
Me.txtCanvasWidth.Text = thePatternOptions.CanvasWidth.ToString
Me.txtCanvasHeight.Text = thePatternOptions.CanvasWidth.ToString
End Sub
I change the options in the options form. How can I get those changes back to the calling form? Do I need to somehow pass a handle of the calling form to the constructor to get the changed values back to the calling form? Is there some way to pass a handle to the options form so that changes made to options will be pushed back to the calling form?
