How To Call Stored Procedure And Retrieve Single Return Value
Jul 22, 2010
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 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.
Why I can NOT get the return value (Scope_Identity) by executing my own Stored procedure (SQL Server 2008) via this below code written in VB.NET 2008? The SP inserts the new record into Table1 but I have 0 as the return value!What's wrong with it?here is my vb.net code and my SP:
Public Function Insert(ByVal Obj As entity, connectionString As String) As Integer Dim ScopeIdentity As Integer Dim Connection As New SqlConnection(connectionString)
I have a stored procedure in SQL Server for generating transaction numbers.how to call the Stored Procedure from VB.NET and how will i get the value that is returned from the procedure into the front end.
I am having problems getting the return value from a stored procedure.As I said the last time, while I am an old programmer, I am new to visual languages.The code is as follows:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim strServerName As String Dim intServerID As Integer[code]....
From what I have read this should work. I think I have declared the parameters correctly.When I run the stored procedure from SQL it returns the correct value so I know the problem is in VB.It is a simple stored procedure, however, I am trying to remain consistent and use stored procedures as much as possible.
i get an "This SqlTransaction has completed; it is no longer usable." error everytime i run my code:
the main code
If DBOpen() = True Then Try 'begin transaction
[Code].....
i specified the transaction of sqlcommand named cmd via the Public Sub BeginTranscation. but, is this correct?
also, the error points to the Public Sub RollbackTransaction if the insert to the stored procedure fails. : "This SqlTransaction has completed; it is no longer usable."
how can i perform multiple stored procedure calls within a single transaction correctly?
So I want to erase the guid @value from the database and retrieve the return value from my stored procedure [code]object name 'value' not valid..Net SqlClient Data Provider0.
I am trying to create stored procedure that gone return varchar value, and that value I need to display in textbox. This is the code for stored procedure:
the stored procedure is within a transaction. I want to get the inserted values after calling the stored procedure. My problem is, I don't know if that is possible because the transaction is not yet commited.
I am using vs 2008 doing a winforms app in vb.net. I have a database with a single table, that has two columns, in it and a stored procedure. The stored procedure is supposed to take an input value, match that value against one column in the table and then return the corresponding value from the other column; except it doesnt.It returns 1 or 0
ALTER PROCEDURE dbo.getgamenumber(@outputnumber bigint OUTPUT, @inputnumber bigint) AS
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]...........
Created an XSD file that represents my table structure from my database. Created a class file to hold my functions such as the one below.
Code sample:
Public Function GetUser(ByVal UserID As String) As xsdUser.UserDataTable Dim SqlConn As New SqlConnection(ConfigurationManager.ConnectionStrings("MyDatabase").ConnectionString)
[Code]....
Now it seems odd to me to have two files doing what should be contained within just one file. I feel like I should have one class file called "User" and have member variables in there along with the class functions like the one above. But all the tutorials I see are using these data tables. On top of that I'm not sure how to handle the if statement at the end of the function. I don't think I would want to return a whole DataTable since I should only have one row, and I also don't know how I would handle an error if my function is supposed to return a data table. I suppose I could return an empty one and then if the table is empty in my code then I would handle it there, but this also seems messy.
Is this the common way of retrieving information from a stored procedure? Or is there a more up-to-date method that I'm not seeing in my search results?
i am trying to find examples of getting data back from a stored procedure that has no parameters sent to it nor has any returned output parameter. Though it does display data.How can i get that from my code im using below?
Dim myCommandSQL As New SqlCommand Dim myReaderSQL As SqlDataReader = Nothing Dim intX As Integer = 0[code]....
The @return_value i just put there to see what would happen but i got nothing returned.
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 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
[Code]...
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)
I have an Excel workbook which I created a sub-routine to insert data from the selected worksheets to a Sql database with the Sql stored procedure. I tested the sp using the Sql Management Studio and it works fine. However when I tried to call that store procedure and it failed. [Code]
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()
Dim data As DataTable = DataAccess.ExecuteDataSet("AuthenticateWebServiceClient" _ , New SqlParameter("@ClientID", ClientId) _ , New SqlParameter("@Password", Password) _[code]....
Except PrepareSPCommand isn't recognized by VS. Does anyone know the correct way to convert this function to C#.
I want to be able to call a certain stored procedure based upon different criteria. May I do something like on lines 6 through 12 ? If so, am I properly creating my command object on line 3?
1 Dim connString As String = ConfigurationManager.ConnectionStrings("EMRConnectionString").ConnectionString 2 Dim conn As New SqlConnection(connString) 3 Dim sprocComm As New SqlCommand
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 would like to create a stored procedure that will call any webservice by passing to the stored procedure the webservice name/url and its parameters. I would like this instead of adding web refference each webservice one by one.
