LINQ Stored Procedure Return Value To A String Array?
Mar 24, 2011
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()
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?
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 '?'"
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.
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 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.
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
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 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
My application produces this error System.Data.SqlClient.SqlException: Login failed for user..This started after I added a stored proc in my dbml file. It works fine in my local enviroment, but throws that error when deploy to staging sever. the user it displays is foreign to me?
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)
Trying to convert XML file to string and pass to stored procedure. Dim fs As FileStream = File.Open(fileUpload1.PostedFile.FileName, FileMode.Open, FileAccess.Read) Dim buffer(fs.Length) As Byte fs.Read(buffer, 0, fs.Length - 1) txtRawXML.Text = System.Text.ASCIIEncoding.ASCII.GetString(buffer)
When I tried to upload file I got error. The error description is 'A name contained an invalid character.'. Could not find prepared statement with handle 0. Could not find prepared statement with handle 0. sp_xml_removedocument: The value supplied for parameter number 1 is invalid. The statement has been terminated.
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.
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.
In a nutshell, I am selecting values from a checked box column in a grid view. After checking the boxes I have a function that concatenates each customer number into a string called @CusList to use a parameter for a stored procedure Public Function SelectCusList()
Dim CusShow As String Dim CusStr As String Dim CusList As String CusStr = ""
