String Variable For Use With LINQ To SQL Class Stored Procedure Call Has Weird Message?
Feb 4, 2010
In my project I am using a LINQ to SQL class that contains a stored procedure which includes a string value as an output parameter.So to capture that, I created a string variable as follows in the procedure:Dim spOutput As String? However, when I do this I get the following message "Type 'String' must be a value type or a type argument constrained to 'Structure' in order to be used with 'Nullable' or nullable modifier '?'"

I have a combobox named cbEmpState, I need to call a stored procedure named 'spStateList' and have it fill the combobox. I'm having a hard time finding examples of this online. The stored procedure is in my dbml file.
Here's the stored procedure
ALTER PROC spStateList
AS
SELECT * FROM states ORDER BY StateName ASC

I have a stored procedure in DBML and I try to pass the result to "sqlQryArray" as an array(1 dimensional array). But the bottom code causes error like below message. What else should be done?
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'.
The return result from stored procedure is a just list of first names of students(only one column)
Dim sqlQry = aaaLINQ.stp_GetSomething(bbb,ccc,ddd)
Dim sqlQryArray As String() = sqlQry.ToArray()

My application has a variable VAR_1 that is boolean, this name is also stored in database.
Now I need to set VAR_1 value in my app by reading database and asign x value,
How do I call VAL_1 from a string?, this is:
Dim VAL_1 as boolean
Dim str as string = myTable.Rows(0).item("x") <--- Here's the name "VAL_1"
But I just can't find how to call VAL_1 by converting "VAL_1" to variable

I connected to the Informix server using RazorSQL, created a stored procedure and tested it, getting the expected answer, so the procedure exists in the database in some form.
I then run the following code:
If ConnectToInformix() Then
Dim cmd As New IfxCommand("dc_routeHasOutstandingQuantity", conn)
cmd.CommandType = CommandType.StoredProcedure
[Code]....
This error does not occur when calling the stored procedure from a live SQL connection.

I am a newbie to vb.net and sql server. My responsibility is to build a vb.net function that when a scanner scans an object, it would take the scanned string and call a stored procedure to get a row of data that match that scanned string and pass the data row to an application that would print out a label.below is my vb.net and sql server stored procedure script
1. Do I have to come up with a public class in order to store my row of data to pass it on to a different vb.net application that would take that data row and print out a label?
2. In my stored procedure, how would I return the founded data row to the vb.net function?
Module makeLabel
Public Class AMGCdata
Public fileName As String[code]...........

I am trying to call a stored procedure from a SQLExpress2005 data base on a Windows 2003 Domain Controller. I keep having errors when I run my code in debug mode.
Stored procedure name = InsertUsersFromAD
Server name where SQL resides = MIS631
Database Name = AdminGUI

I've tried making the Data Source = \MIS631SQLEXPRESS also, which didn't seem to work. I am trying to finish up a school project and this is the only thing not working.

way to create and initialize SqlParameters in VB.NET? Using 3 lines per variable seems quite excessive. Unfortunately the constructors for this class are rather ridiculous, so I'm thinking of just writing my own sub for initializing each parameter. This is how I've been doing it.
Dim ID As New SqlParameter("@ID", SqlDbType.Int)
ID.Value = val
query.Parameters.Add(ID)
[Code]....

in my SQL 2005 database I have defined this stored procedure:
CREATE PROCEDURE [dbo].[CheckOrders] (
@PK_Customer uniqueidentifier,
@Amount bigint OUTPUT)
[code]....
When I check the value of nAmount it stil contains the original value -1 the output value didn't return from the stored procedure although the number of records updated is 0 or more. The procedure was checked, it works and there are records updated and the value of @Amount is SET to a value 0 or more. I just don't get the values back. eventough the parameter @Amount is defined as OUTPUT. I also tried with outParam.Direction = Data.ParameterDirection.InputOutput instead of outParam.Direction = Data.ParameterDirection.Output . Same result. How do I get the value back from the stored procedure?

I've been trying to figure out how to call an Oracle 10g stored function and insert the return value into my VB.NET application. Stored procedures I've been already able to figure out, but I have no idea about functions.I have the parameter set to send to the function, the oracle function works perfect, but what VB coding to I need to get that return value. The return value is a CHAR.
Again the Oracle DB is in their 10g release.
My version of VB.NET Is Visual Studio 2010.
Also I've beent trying to use the Imports System.Data.OracleClient namespace but it comes up with an error saying its not available. Right now I use System.Data.OleDb. How can I import the oracleclient?

I am creating a front-end application for my company to track job details, customer appointments, upcoming appointments, and more. I had a developer create a back-end SQL database, which includes all of the corresponding stored procedures, such as insert, delete, update, detail, list.We are running SBS 2008, which includes Sharepoint for our internal website. So, I would like the final application to be hosted on our internal website.
I've talked to three different developers and all three had conflicting opinions regarding development. Where do I begin in the development of the application? Which template should be used? How are the stored procedures utilized? How can I create a button to call the stored procedure?

I used the same lines of codes to call a SQL server store procedure to export sql data to an XML file:
1. If I call the stored procedure from a window form application, it works and generates the file at the designated location.
2. If I call the stored procedure from a window service application with a setup project, and the install process run well, and I started the service, and checked the event log, it showed the service start successfully, BUT it FAILED to generate the file at the destination folder. I also run everything as administrator, but it still failed to generate the file. It made me wonder if a window service can call a stored procedure. Because, again, mine ran fine with the window form appl, but window service, I would like to have your sample codes. I have googled around for 3 days now, but could not find the answer. I use vs 2008, sql server 2008, and Windows 7

I am selecting a distinct user from IT_Cases_List and stored it in an arraystaff(). From this array, I will then call a Stored Procedure to count the no of cases attended by this user,(arraystaff(i)) and loop it until arraystaff.length-1
but the problem is that the count does not tally.
Sub getStaff(ByVal month As String)
If Not con.State = ConnectionState.Closed Then
con.Open()
[Code]....
ok, i've called only once getcases but i'm still having the same problem.
this is what i get when i run the program:
if i get Count(*) from the database, the total no of cases i should be getting is 132, whereas the total of cases i get from the program is 157 (7+7+20+20+49+49+5)
if i run the query from sql, this is what i should be getting
i notice that the Count number gets duplicated (7,7,20,20,49,49,5) instead of (7,20,49,5,10,27,13)

I'm new to LINQ and am having a problem getting proper results from a simple (working) stored procedure that takes no parameters and returns a single Integer. When calling this sproc with LINQ its returnvalue is always 0. When run using tableadapter or directly on the sql server it works, returning 6 digit values like 120123.
Here is my LINQ code:
Dim MeetingManager As New MeetingManagerDataContext
Dim MeetingID As Integer = MeetingManager.NewMeetingID().ReturnValue Here is the NewMeetingID procedure:
ALTER PROCEDURE [dbo].[NewMeetingID]
AS
SET NOCOUNT ON
BEGIN

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?

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.
