SQLDataSource.Update Returning Negative Value
Jun 9, 2008Does anyone know why would SQLDataSource.Update method return a negative value even though its updating records correctly?
Its happening with .NET 2.0.

QA Returning Negative #s As Positive
Mar 30, 2004Hey guys,
I have a very peculiar issue going on. I have a table that contains a decimal(18,2) column called "Amount". Looking at this table through Enterprise Mgr, I can see that there are values in there that are negative. However, when I run a query in Query Analyzer, it displays all the negative values as positives.
The only workaround I've found right now is to change the column type to "real" and then change it back to decimal(18,2), and it starts showing the negatives as negative. However, without performing this absurd workaround, it doesn't work.
Is there a known bug in QA that would manifest itself as this? What is the cause for this?
Thanks in advance.
Returning Identity With SQLDataSource
Mar 25, 2008Hello all,I have a sqldatasource that inserts data to the database but I want to get the ID from an Identity field after I am done inserting the data. How can I best do that? I'm not using a stored procedure to do this. <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:onepduConnectionString %>" InsertCommand="INSERT INTO [tblaccounts] ([fname],[lname], [address], [city], [state], [zip], ,[phone],[credits]) VALUES (@fName,@lname, @address, @city, @state, @zip, @email, @phone, @credits)> <InsertParameters> <asp:FormParameter Name="fname" FormField="FirstNameTextBox" Type="String" /> <asp:FormParameter Name="lname" FormField="LastNameTextBox" Type="String" /> <asp:FormParameter Name="address" FormField="AddressTextBox" Type="String" /> <asp:FormParameter FormField="cityTextBox" Name="city" Type="String" /> <asp:FormParameter FormField="stateTextBox" Name="state" Type="String" /> <asp:FormParameter FormField="zipTextBox" Name="zip" Type="String" /> <asp:FormParameter FormField="emailTextBox" Name="email" Type="string" /> <asp:FormParameter FormField="phoneTextBox" Name="phone" Type="string" /> <asp:Parameter Name="credits" DefaultValue=0 /> </InsertParameters> </asp:SqlDataSource>
View 2 Replies View RelatedProgrammatic Use Of SQLDataSource Not Returning Dataview
Sep 4, 2007I am creating an ad-hoc reporting module for my website. The user may select a list of columns and specify the WHERE for the report. I build the select statement and the where statement and pass the info to a stored procedure. The stored procedure accepts 3 select parameters and a 3 wherestmt parameters. I finally got the SQLDatasource to work by setting the parameter values in the Selecting method of the SQLDatasource. Binding it to a gridview shows me all my values. Now, I am trying to programmatically call the select method of the SQLDatasource so I can get a dataview or datareader to manipulate further. I am getting an null back when I call the select method. Any ideas why? or a workaround?

Returning Amount Of Rows From Sqldatasource
Oct 10, 2007TotalSelected.Value = SqlDataSource1.SelectCommand = "SELECT COUNT(*) FROM tblNews";
the reason i am tring to do this is so if i can find out the amount of rows before sqldatasource selects for details view then i can make the sqldataesource select depends on total minus 5 so e.g. if total 200 then - 5 so i can select bottom 195 so it misses top 5 for details view any1 any ideas?
Thanks Andy,
SqlDataSource And SSMSE Returning Different Results For Same SELECT Command
Oct 2, 2007Hi,
Hope you guys won't mind this rather newbie question. I'm writing a simple blog page for my website and have created a SqlDataSource which queries the database for a list of blog post titles (from the web.Blog table) and the number of comments (from the web.BlogComments table). The SqlDataSource control is:
<asp:SqlDataSource ID="sourceBlogArticles" ProviderName="System.Data.SqlClient" connectionString="<%$ ConnectionStrings:myDatabase %>" runat="server" SelectCommand="SELECT gb.blogID, gb.title, gb.description, gb.tags, gb.dateAdded, COUNT(gbc.blogID) AS noOfComments FROM web.Blog gb LEFT OUTER JOIN web.BlogComments gbc ON gb.blogID = gbc.blogID GROUP BY gb.blogID, gb.title, gb.description, gb.tags, gb.dateAdded ORDER BY gb.dateAdded"></asp:SqlDataSource>
This works perfectly well if each blog entry in the web.Blog table has associated comments in the web.BlogComments table. However, if there are no comments yet defined in the web.BlogComments table for that blogID then no row is returned in ASP.Net (as checked with a GridView control or similar linked to the data source to view what I get)
HOWEVER, I think the SELECT command IS correct: if I use the select command as a query in SQL Server Managment Studio Express, I do get the rows returned, with 0 for the number of comments which is what I would expect for that query:
blogID, title, description, tags, dateAdded, noOfComments
1, title 1, description for title 1, tag1, 2007-09-27 06:49:03.810, 32, title 2, description for title 2, tag2, 2007-09-27 06:49:37.513, 03, title 3, description for title3, tag3, 2007-10-02 18:21:30.467, 0
Can anyone help? The result from the SSMSE query is what I want, yet when I use the very same SELECT statement in my SqlDataSource I don't get any rows returned if the BlogComment count is zero (in the above example I get only the first row). Many thanks for any suggestions!
SQLdatasource Wired To A Stored Procedure Not Returning Records.

Update The Selected Rows Before Returning Them In One Command.
Mar 14, 2008
Hello,
I have an external process that polls message rows from a table. apon taking them, it also needs to mark them as taken. there is a status column in the table. marking messages as taken will change the value of status.
How can i perform both these operations in one command? Select the top x rows where their status is equal 1, then update the status of those same rows to a value of 5 for example.
I could iterate through the result of hte intial select and change the status 1 by 1 using a cursor, but this seems like a slow option.
Any other ideas?
Thank you.
SQL Server 2008 :: Why CDC Returning Insert / Delete When UPDATE A Row In Table
Mar 15, 2013I am experimenting with using CDC to track user changes in our application database. So far I've done the following:
-- ENABLE CDC ON DV_WRP_TEST
USE dv_wrp_test
GO
EXEC sys.sp_cdc_enable_db
GO
-- ENABLE CDC TRACKING ON THE AVA TABLE IN DV_WRP_TEST
USE dv_wrp_test
[Code] ....
The results shown above are what I expect to see. My problem occurs when I use our application to update the same column in the same table. The vb.net application passes a Table Valued Parameter to a stored procedure which updates the table. Below is the creation script for the stored proc:
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
if exists (select * from sysobjects where id = object_id('dbo.spdv_AVAUpdate') and sysstat & 0xf = 4)
drop procedure dbo.spdv_AVAUpdate
[Code] ....
When I look at the results of CDC, instead of operations 3 and 4, I see 1 (DELETE) and 2 (INSERT) for the change that was initiated from the stored procedure:
-- GET CDC RESULTS FOR CHANGES TO AVA TABLE
USE dv_wrp_test
GO
SELECT *
FROM cdc.dbo_AVA_CT
GO
--RESULTS SHOW OPERATION 1 (DELETE) AND 2 (INSERT) INSTEAD OF 3 AND 4
--__$start_lsn__$end_lsn__$seqval__$operation__$update_maskAvaKeyAvaDescAvaArrKeyAvaSAPAppellationID
--0x0031E84F000000740008NULL0x0031E84F00000074000230x02119Test26NULL
--0x0031E84F000000740008NULL0x0031E84F00000074000240x02119Test36NULL
--0x0031E84F00000098000ANULL0x0031E84F00000098000310x0F119Test36NULL
--0x0031E84F00000098000ANULL0x0031E84F00000098000420x0F119Test46NULL
Why this might be happening, and if so, what can be done to correct it? Also, is there any way to get the user id associated with the CDC?
Update Not Working In An SQLDataSource
Sep 6, 2006I'm new to ASP and ASP.NET so I used the Wizards in Visual Web Deverlopment Express 2005 to build the following code:<asp:DetailsView ID="DetailsView" runat="server" DataSourceID="TracksDataSource"

</asp:SqlDataSource> However, when I click Edit, change something, and then Update it doesn't update the database. However, if I remove the DataField bindings and use the AutoGenerateRows feature it works fine.
Using XML As An Update Parameter In A SqlDataSource?
Nov 6, 2006One of the requirements of the UpdateParameters for a GridView I'm building is that the fields that are being edited via EditItemTemplates are passed back to the UpdateParameter as XML. How would I go about combining the fields from the GridView/EditItems into an XML string that I can set as an asp:Parameter?
Thanks.
OldValuesParameterFormatString SqlDataSource Update
Mar 15, 2007OK guys, I'm sure I'm doing something stupid here but after 2 days I find myself extremely frusted... Any help would be appreciated
I'm tring to write an update procedure for an SqlDataSource control that will allow me to chage the primary key values of a record in the table. Everything seems to work fine with the exception of obtaining the old values (the primary key before its changed by the end user) during the update. I've read several articles on the web an in the forums on this topic. Much of it has to do with the .NET beta version alteration from "original_{0}" to "{0}". I believe those conversations do not describe my problem.
Anyhow, onto some source code. Here's the ASP source code for a grid view and sql data source. <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"

<asp:Parameter Name="sortOrder" Type="Single" />
</InsertParameters>
</asp:SqlDataSource>I added a text box for every field in the grid to the form and update the fields when the user selects a record in the GridView. I then added an Update button to the form and tied the event to this procedure: Protected Sub bUpdate_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles bUpdate.Click
'if the user has not entered key fields!
If missingKeyFields() Then
Exit Sub
End If
Dim count, so As Integer
Dim uDomain, uid As String
'parse out the user id and domain.
Try
If HttpContext.Current.User.Identity.Name = "" Then
uid = "unknow"
uDomain = "unknown"
Else
uid = HttpContext.Current.User.Identity.Name
uid = uid.Substring(uid.IndexOf("") + 1)
uDomain = uid.Substring(0, uid.IndexOf("") - 1)
End If
Catch ex As Exception
uid = "unknow"
uDomain = "unknown"
End Try
'fill in the parameters
'@productName, @productURL, @productSupportURL, @description, @modified, @userid, @useridDomain, @sortOrder
Me.SqlDataSource1.UpdateParameters.Item("productName").DefaultValue = Me.tbProductName.Text
Me.SqlDataSource1.UpdateParameters.Item("productURL").DefaultValue = Me.tbProductURL.Text
Me.SqlDataSource1.UpdateParameters.Item("productSupportURL").DefaultValue = Me.tbProductSupportURL.Text
Me.SqlDataSource1.UpdateParameters.Item("description").DefaultValue = Me.tbProductDescription.Text
Me.SqlDataSource1.UpdateParameters.Item("modified").DefaultValue = Now
Me.SqlDataSource1.UpdateParameters.Item("userid").DefaultValue = uid
Me.SqlDataSource1.UpdateParameters.Item("useridDomain").DefaultValue = uDomain
Me.SqlDataSource1.UpdateParameters.Item("sortOrder").ConvertEmptyStringToNull = True
If Integer.TryParse(Me.tbSortOrder.Text, so) Then
Me.SqlDataSource1.UpdateParameters.Item("sortOrder").DefaultValue = so
Else
Me.SqlDataSource1.UpdateParameters.Item("sortOrder").DefaultValue = ""
End If
'insert the record.
count = Me.SqlDataSource1.Update()
Me.lCommandInfo.Text = count.ToString + " record was updated."
End Sub
The net result of the procedure is the message "0 record was updated." when I select a record in the gridView and then edit the "productName" field and click Update.
In an attempt to trace down the problem I added this code: Protected Sub SqlDataSource1_Updating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceCommandEventArgs) Handles SqlDataSource1.Updating
Message.Text = e.Command.CommandText
Message.Text += "<br>"
For lp As Integer = 0 To e.Command.Parameters.Count - 1
Message.Text += e.Command.Parameters(lp).ParameterName + "=" + e.Command.Parameters(lp).Value
Message.Text += "<br>"
Next
End Sub
The message label displays the following text:UPDATE homePageList SET productSupportURL = @productSupportURL, description = @description, modified = @modified, userid = @userid, useridDomain = @useridDomain, sortOrder = @sortOrder, productName = @productName, productURL = @productURL WHERE (productName = @original_productName) AND (productURL = @original_productURL)
@description=interesting!
@modified=3/15/2007 4:07:31 PM
@userid=unknow
@useridDomain=unknown
@sortOrder=
@productName=ok22
@productURL=http
@productSupportURL=http
@original_productName=ok
@original_productURL=ok
Notice how the "@original_productURL" has the same value as the "@original_productName"? This should not be the case. The @original_productURL should equal "http" since I didn't update the field's value. It seems like the second field of the primary key is not getting updated or passed to the @original_productURL parameter. Since .NET handles the @original_{0} parameters I don't know why the field isn't being properly updated.
Any thoughts on how to track down the root cause of my problem... Or better yet any thoughts on a work around to my problem?
Thanks,Johnny
Need Help With SQLDataSource Update Parameter

Help With UPDATE With SqlDataSource And A Repeater
Jan 15, 2006Hi,
I have a repeater which i need to build editing capabilities into in a similar way as the GridView, just a little unsure how to tie it together. Ideally i would like to use a GridView as this would do all of the work for me however it looks like I need to go with the repeater due to the nested nature of the data I am working with.
What is the best way to go about updating the data source from within a repeater? I have already built the edit interface with some MultiViews in the Repeater control and handling the ItemCommand event, just not sure how to actually update the data source.
Can I still use the SqlDataSource wizard to generate all of the SQL for me? If so, within the ItemCommand event handler I have the data i want to update back to the database by using the FindControl method and retrieving the Text, but how do i get this data into the SqlDataSource object and update the database?
Are there any samples available which show how to update a datasource using a repeater?
Your help is much appreciated

SQLDataSource Update Using Parameters Not Working
Jul 10, 2006I'm passing a parameter to a stored procedure stored on my sqlserver, or trying to atleast. And then firing off the update command that contains that parameter from a button. But it's not changing my data on my server when I do so.
I'm filling a dropdown list from a stored procedure and I have a little loop run another sp that grabs what the selected value should be in the dropdown list when the page loads/refreshes. All this works fine, just not sp that should update my data when I hit the submit button.
It's supposed to update one of my tables to whatever the selected value is from my drop down list. But it doesn't even change anything. It just refreshes the page and goes back to the original value for my drop down list.
Just to make sure that it's my update command that's failing, I've even changed the back end data manually to a different value and on page load it shows the proper selected item that I changed the data to, etc. It just won't change the data from the page when I try to.
This is what the stored procedure looks like:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
ALTER PROCEDURE [dbo].[UPDATE_sp] (@SelectedID int) AS
BEGIN
UPDATE [Current_tbl]
SET ID = @SelectedID
WHERE PrimID = '1'
END
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Can't Update A Record Using A DetailsView And SqlDataSource
Feb 13, 2007Hi,I'm trying to create a registration page that I've divided into multiple pages (first page for basic details, next page for address, etc.). I insert the record in the first page, and update it in the other pages. I pass the newly created ID to the other pages using the Page.PreviousPage property. In the second page, I have the SqlDataSource configured as "SELECT * FROM [Table] WHERE ID = ?", and the UpdateCommand is "UPDATE .... WHERE ID = ?". In Page_Load, I am updating the SelectCommand to "SELECT ... WHERE ID = " & intID, and the UpdateCommand similarly. The I do a dtlsvw.Databind()But when I go to the next page (the newly created ID is being passed properly), the update doesn't do anything. The new record doesn't contain the values in the detailsview. Can somebody help me out? Thanks,Wild Thing
View 2 Replies View RelatedSQLDataSource: Update 2 Tables With 1 UpdateCommand?
Mar 16, 2007I have a Gridview (edit enabled), connected to a SQLDataSource.
SQLDataSource populates the gridview from 1 SelectCommand.
figure1:
ColumnA | ColumnB | ColumnC
I have 2 SQL Server 2005 tables: Table1 and Table2
Now on my SQLDataSource's UpdateCommand, I want the value of ColumnB to go to Table1's ColumnB, and ColumnC to go to Table2's ColumnC.
How do I do this?
I understand I can't do this with 1 UPDATE-SET sql query. Maybe I can with stored procs or something, but im kinda noobish when it comes to this. How? Thanks
Error During SqlDataSource.Update() Instruction
May 29, 2007Hi, I have such a problem:I try to update (or insert) a row in my table and i fail althought i,ve read many posts here. I.ve created a button and "on_click" event to this button and want that event to update or insert a record in my table. I wrote: protected void selectButton_Click(object sender, EventArgs e) { String taskID = projectsGridView.SelectedRow.Cells[0].Text; usersSqlDataSource.UpdateCommand = "update [Users] set [TaskID]=@task where [UserID]=1"; usersSqlDataSource.UpdateParameters.Add("task", taskID); usersSqlDataSource.Update(); } The application creates error in the last line of code (usersSqlDataSource.Update();) and i receive such an error:You have specified that your update command compares all values on SqlDataSource 'usersSqlDataSource', but the dictionary passed in for oldValues is empty. Pass in a valid dictionary for update or change your mode to OverwriteChanges. For me it looks like there is a problem while setting parameters. Shall i change some properties of the sqlDataSource or GridView? Please help..
View 2 Replies View RelatedHelp: Programmatically Update Data From An SQLDataSource (C#)
Jul 3, 2007ello all
Would someone be so kind as to save me from getting balder through pulling my hair out.
My aim is to extract data from a database using SQLDataSource, then edit the data and update the database using the SQLDataSource.
I have achieve the problem of retrieving the data from the sqlDataSource:DataView openRemindingSeats = (DataView)SqlDataSource2.Select(DataSourceSelectArguments.Empty); //Int32 openRemindingSeats = SqlDataSource2.Select(DataSourceSelectArguments.Empty), DataView;
foreach (DataRowView rowProduct in openReminding) { //Output the name and price lbl_NumOfSeatsLeft.Text = rowProduct["Remaining"].ToString();
}
Within the sqlDataSource the sql code is as follows:SELECT [refNumber], [refRemaining] FROM [refFlights] WHERE ([refNumber] = @Number)
So at the moment my problems is being able to edit and update data to the same SELECTed data.Thank you for any help that you might have...

SqlDataSource: Insert, Update And Delete Not Available
Jan 3, 2006Hello Guys,
I’m trying to create a sqlDataSource using the wizard, I can get the select statement, the here clause and the order by clause but when I click on the Advanced button the options to generate the insert, update and delete statements are not available. Does anyone know what am I doing wrong?
How To Put New Data Into SqlDataSource Update With Concatenated Key?
Jan 26, 2006Here is the problem.
I have table such as this
PK selection VARCHARPK selection_choice VARCHAR show BIT
When I use the sqlDataSource to create an update it creates this.UPDATE lu_selection_choices SET show = @show WHERE (selection = @selection) AND (selection_choice = @selection_choice)
Now this is OK, but when you perform an update and in say a details control you change the selection_choice the value of the parameter @selection_choice is going to be equal to the old data. So it performs a successful update on show which isn't being changed selection_choice is.
So the questions is. Is there anyway to tell the update function of the datasource to insert the a new parameter with the SET selection_choice = @SOME NEW PARAM slection_choice?
Thanks,
Darren King
How To Trigger The Update Command Of The SQLDataSource
Jun 13, 2006Hi - I'm using .net2, and have a gridview, populated by a SQL Datasource (Edit, Insert, Delete, Select).
Like we all used to do with the datagrid, I've added text boxes into the footer, and a link button, which I'd like to use to fire the Update command.
How do I get the link button to trigger the update command?
Thanks, Mark

View 1 Replies View RelatedSqlDataSource Update Doesn't Work When Using Parameter
Feb 3, 2007Hi all:
I have a list of items (actually a relation in which a user has selected an item, along with a rating for the item) in an Access database table, connected to my app with a SqlDataSource and bound to a repeater. The repeater displays the items to the user along with a dropdown box to show the rating, and allow the user to update it. The page connects and displays correctly.
My problem is that when the user submits the page and I iterate through the repeater items to update each rating, the updates are not being completed in the database. The update works if I hard-code a value for the rating into the query itself, but not when using an updateparameter (pTaskRating below). In other words if I replace pTaskRating with '5', all the correct records will be found and have their ratings updated to 5. That means that the mySurveyId and pTaskId(DefaultValue) parameters have to be working, because the right records are found, but I can't seem to update records based on the DefaultValue of the pTaskRating parameter, even though I can verify that the DefaultValue is correct by placing a watch on it. It seems that my problem must be in my use of that particular parameter in the query, either in properties of the parameter or in the value assigned to it. I am extremely frustrated - any ideas would be greatly, greatly appreciated. Thanks!

The table I'm pulling from and updating looks like this:
SURVEY_ID (Text 50), TASK_ID (Long Int), RATING_ID (Long Int)
Here's my ASPX for the main data source:
<asp:SqlDataSource ID="sqlTaskSelections" runat="server" ConnectionString='Provider=Microsoft.Jet.OLEDB.4.0;Data Source="abc.mdb";Persist Security Info=True;Jet OLEDB:Database Password=xyz' ProviderName="System.Data.OleDb" SelectCommand="SELECT [SURVEY_ID], [TASK_ID], [RATING_ID] FROM [TBL_TASK_SELECTION] WHERE [SURVEY_ID] = mySurveyId" UpdateCommand="UPDATE [TBL_TASK_SELECTION] SET [RATING_ID] = pTaskRating WHERE ([SURVEY_ID] = mySurveyId) AND ([TASK_ID] = pTaskId)">
<UpdateParameters>
<asp:SessionParameter Name="mySurveyId" SessionField="SurveyId" DefaultValue="" /><asp:Parameter Name="pTaskId" DefaultValue="" /><asp:Parameter Name="pTaskRating" DefaultValue="" />
</UpdateParameters>
And here's the repeater (the Task ID and Rating are stored in hidden fields for easy access later):
<asp:Repeater ID="rptTaskSelections" runat="server">
<HeaderTemplate><table border="0"></HeaderTemplate>
<ItemTemplate>
<tr class="abctr"><td class="normal"><asp:DropDownList ID="cbRatings" runat="server"></asp:DropDownList><asp:HiddenField ID="hTaskId" Runat="server" Visible="false" Value='<%# Eval("TASK_ID") %>' /><asp:HiddenField ID="hRating" Runat="server" Visible="false" Value='<%# Eval("RATING_ID") %>' /> <%# Eval("TASK_ID") %></td></tr>
</ItemTemplate>
<FooterTemplate></td></tr></table></FooterTemplate>
</asp:Repeater>
And here's the page load and submit VB:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not Page.IsPostBack Then
'BIND / LOAD RATINGS TO DROPDOWN BOXES HEREDim i As IntegerDim cbCurrentRating As DropDownListDim hCurrentRating As HiddenFieldrptTaskSelections.DataSource = sqlTaskSelectionsrptTaskSelections.DataBind()

Next
End If
End Sub
Protected Sub btnSubmitRateTasks_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSubmitRateTasks.Click
