Forms Data Controls :: Returning Single String Result Through Stored Procedure
Jun 22, 2010
I am trying to return single string result through a stored procedure and Linq. This works fine when I test the stored procedure but it is not returning the value to the page. The value returned is always 0 which is the return value. This is the stored procedure:
ALTER PROCEDURE Login
@Password nvarchar(50) output
This is the vb
ALTER PROCEDURE Login
@Password nvarchar(50) output
Where Customers.CustomerName=@CustomerName is the code created by the designer
This is the designer function
Public Function Login(<Parameter(Name:="CustomerName", DbType:="NVarChar(50)")> ByVal customerName
As String, <Parameter(Name:="Password", DbType:="NVarChar(50)")> ByRef password As String) As IntegerDim result
As IExecuteResult = Me.ExecuteMethodCall(Me, CType(MethodInfo.GetCurrentMethod,MethodInfo), customerName, password)
password = CType(result.GetParameterValue(1),String)
I am having problems returning a string value through a stored procedure/linq to a label. Everything works fine if I return an integer value but I cant get a string value to bind to a label. I get the error message
Microsoft.VisualBasic.CompilerServices.Conversions.ParseDouble(String Value, NumberFormatInfo NumberFormat) +201 Microsoft.VisualBasic.CompilerServices.Conversions.ToInteger(String Value) +66 [InvalidCastException: String "System.Data.Linq.SqlClient.SqlPr" to 'Integer' is invalid‚]
This is the stored procedure ALTER PROCEDURE test AS Select ProductName From Products
This is the vb page Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim db As New DataClassesDataContext Dim product As Integer = db.test.ToString Label1.Text = product End Sub
This is the aspx page <form id="form1" runat="server"> <asp:Label ID="Label1" runat="server" Text=""></asp:Label> </form>
I am bulding a dvd catalog and have a table called DVD which holds all my details about each dvd except Genre, Director and Actor as I want more than 1 Genre, Director, Actor per DVD so put these in seperate tables to avoid repeating the data and used a joining tabe to join the tables so the tables I have are
DVD, Genre, Director, Actor, DVDGenre, DVDDirector and DVDActor
I have now written a stored procedure to pull the info about 1 DVD out of all the tables to display on the webpage I have now got the info I want out of the tables but as the data is now in 1 table I have repeating data is there a way to stop the data repeating the stored procedure i have written is
I call this stored procedure with a dataset. It always returns a 0 but should return a 1 or 2. Does anybody know why it isn't returning a 1 or 2.
ALTER PROCEDURE dbo.sp_InsertLinkVote @LinkId int, @LinkVoter nvarchar(50), @LinkVotesDateTime datetime, @LinkVotesGoodBad bit AS /* SET NOCOUNT ON */ ã€€ If EXISTS (SELECT * FROM LinkVotes WHERE LinkId=@LinkId and LinkVoter = @LinkVoter )RETURN 1 ELSE INSERT INTO dbo.LinkVotes (LinkId,LinkVoter,LinkVotesDateTime,LinkVotesGoodBad)VALUES (@LinkId,@LinkVoter,@LinkVotesDateTime,@LinkVotesGoodBad)RETURN 2
Here is were a call it in my code behind. Dim VoteCheck As Integer Dim InsertVote As New DataSetStoredProceduresTableAdapters.QueriesTableAdapter VoteCheck = InsertVote.sp_InsertLinkVote(LinkId, User.Identity.Name, DateAndTime. Now, True) '0 is a good vote. If VoteCheck = 0 Then
It seems to insert and not insert correctly, I just cannot get it to return the correct value.
I am developing a page in ASP.Net where I have the user enter a letter into a textbox. They then click a submit button and I all of the userids that start with that letter are to be displayed. So I need the SP to go through the database and match first letters with what was entered. Here is what I have as my code for the SP:
CREATE PROCEDURE dbo.exp2 @testchar Char(1) declare @flag as char(2) set @flag = @testchar + '%' select userid from ex_database where userid like @flag
Im trying use a storedprocedure where depending on the status of the room if ='Vacant' And checkIn =date and the result will be put in a gridview, but i kept returning an error that says, "Conversion failed when convertng datetime from character string". Heres the code.
I have problem with a stored procedure and function that return the same shape, but as they are different methods LINQ won' t let me cast between the two. Please see code for the two SPROCs below (This is actually simplified to represent the problem, so please don't spend lots of time explaining alternative ways of writing the function/sproc.)
Table Valued Function "getCategories()" SELECT categoryName, categoryID FROM categories SPROC "getUnusedCategories" SELECT categoryName, categoryID FROM CategoryInstances cI FROM dbo.SMAN_getCategories(@SiteMANID, @SectionID) c LEFT JOIN @EntityResultsTable er
I have a Procedure which should return only 1 Record on selecting record according to Priority.
BEGIN DECLARE @Accounts nvarchar(MAX) SELECT @Accounts = ISNULL([map_user_modules].[Accounts], '') FROM [map_user_modules] WHERE [map_user_modules].[id_user] = 231 AND [map_user_modules].[id_module] = 5 IF ((@Accounts = '') OR (@Accounts = 'All')) SELECT @Accounts = null
BEGIN Select @@ROWCOUNT as Priority2 END IF @@ROWCOUNT = 1 BEGIN Return END
BEGIN Select @@ROWCOUNT as Priority3 END IF @@ROWCOUNT = 1 BEGIN Return END
BEGIN Select @@ROWCOUNT as Priority4 END IF @@ROWCOUNT = 1 BEGIN Return END
In the above statement Suppose we take a scenario where Select @@ROWCOUNT as Priority3 is executed, I get two tables returned, One is the Table returned by Select @@ROWCOUNT as Priority3 and the other is the Table returned by Select @@ROWCOUNT as Priority2 which has no Records. How can I eliminate the Empty table that returns no records.
I am using SqlHelper.ExecuteDataset(MyConnectionString, CommandType.StoredProcedure, "GetInformation", new SqlParameter("@ID", ID));
In my stored Procedure, I am doing a lot of calculation with joins and it took 19 sec to execute at my sql Server 2008. My application had been working perfectly for 5 days but now as database increases, I found a problem that my connection is breaking at that point. At Sql Server, it execute fine but when I add a breakpoint and watch the stored procedure is returning null.
I'm programming a webpage in ASP.NET which displays a list of students not listed as participants in something, and upon clicking a student name shows you a brief summary of their details, so the user can ensure they're selecting the right person. Each student is identified by a unique ID.
My code currently correctly obtains their ID, adds it as a parameter to my stored procedure and executes the procedure;
However, when I try to access the results, with say dv.Table.Rows, I get the following error:
Upon debugging, there don't seem to be any results returned... when running just the stored procedure in SQL Server with the same data, it does return a single row, as expected.
Just after some advice I have a stored procedure that returns several tables. I then need to loop through the tables and create dynamic gridviews using the data. At the moment this stored proc is called using
I have used an xsd file to populate everthing else, but due to this returning multiple tables i wasn't sure how this works should it just be in its own xsd? as all the oather i just get a datatable where as with this i need a dataset... how this makes sense...
I had requirement that i need to display four charts in one report. The data for the report is given through stored procedure. In this stored procedure each chart have its own result set. ie., the Stored Procedure is returning four result sets.
I have a small query can we store three different stored procedure data into single dataset (in multiple tables). I am asking this because I have three stored procedure and when I run them simultaneously it takes less time to execute and when I run them separately it takes more time and I want to use all three stored procedure in page load. Environment - SQL Server 2005, ASP.net 2.0
I am using a sql stored procedure which returns multiple result sets. By default Sql Datasource is binding the first result set to gridview. I want the second result set to be binded. I browsed all the properties in Sql datasource but could not find one to set this.
I want to execute a method on VB.Net to return a date which is in the stored procedure. I tried using ExecuteScalar but it doesnt work it retruns error
'Implicit conversion from data type datetime to int is not allowed. Use the CONVERT function to run this query'
below is the code
Public Function GetHolidaydate(ByVal struserID as String) As DateTime Dim objArgs1 As New clsSQLStoredProcedureParams objArgs1.Add("@userID", Me.Tag) objArgs1.Add("@Date", 0, 0, ParameterDirection.Output) Return (CDate(ExecuteScalar(clsLibrary.MyStoredProcedure.GetHolidayDate, objArgs1))) End Function
Here's a stored procedure I created that uses another stored procedure inside it to return a value:
Note the 'exec dirinfo.dbo.d_searchempbyname @TicketSubName' part. That stored procedure will return a single record. What I need is to get a single column from that recordset (in this case, the email address of the employee), and store that value in a variable.
I am having problem in returning a status message (success or failure) from my sql server sp here is the code: [Code]....
"Status" is an output parameter which is supposedly getting the message from sp and we are not able to get its value since "dbCommand1.Parameters["@status"].Value" returns NULL everytime! SP is available on request.
what is the recommended data access strategy for the following environment: single stored procedure, many parameters, asp.net 4.0, sql server 2008, and the stored proc returns 11 different recordsets, all of which get displayed in various different elements too complex and specific to be handled by server controls.
I been trying to get a simple stored procedure called and get its returned value back to a parm. In this case I am trying the simplest one I can make to get it to work and the I can build form there. I have tried to do this about 100 times and I try try and say heck with it and do it with out using a stored procedure and move on but I would really like to figure this out. I created a stored procedure called ReqLineItemTotal. It looks like this
USE [OnBillPROD] GO /****** Object: StoredProcedure [dbo].[ReqLineItemTotal] Script Date: 11/09/2010 14:08:39 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO -- Author: Bill Blair -- Create date: 11-9-2010 -- Description: ReqLineItemTotal -- ALTER PROCEDURE [dbo].[ReqLineItemTotal] -- Add the parameters for the stored procedure here @SessionIDNo nvarchar(50) = 0
AS BEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON; -- Insert statements for procedure here select (select SUM(dbo.TempReqDetail.Amount) from dbo.TempReqDetail,dbo.tblReqAmountTypes where dbo.tblReqAmountTypes.AmountType = dbo.TempReqDetail.AmountType and dbo.tblReqAmountTypes.NumericOpperator = '+' and dbo.TempReqDetail.SessionID = @SessionIDNo) - (select SUM(dbo.TempReqDetail.Amount) from dbo.TempReqDetail,dbo.tblReqAmountTypes where dbo.tblReqAmountTypes.AmountType = dbo.TempReqDetail.AmountType and dbo.tblReqAmountTypes.NumericOpperator = '-' and dbo.TempReqDetail.SessionID = @SessionIDNo) AS LineItemTotal END
From what I understand I should be getting my total back as LineItemTotal. So I want to call it pass it my parm of @SessionIDNo and have its returned value set to my @LineItemTotal parm. Trying to use these stored proc's always seems like way more work than they are worth but perhaps if I ever get the hang of it would make since to me.
am new to entity frame work and having a hell of time building a stored procedure that insertsa value into a table using a Scalar stored procedure and returning the new ID which is a Unique Identifier. I am trying
