Why Is My Update Command Not Working
Feb 18, 2008
hi, i am tryuing to use the gridview as means for the user to be able to edit delete and update columns of the database. however when it is run in the browser it allows the user to edit the fields but when i click on the update button it throws an error. can someone please offer me advice on how i can sort this problem out or provide me with any examples as i cant see what the error is. i used the option in edit columns which allows you to specify you want update delete etc controls added to the gridview. how can i make it so it supports updating? thank you

Hello,
I've created an ssis package that copies or updates data from a table to another.
Essentially I have
DB source
Lookup
conditional split --> update changed rows ole db command
|
|
write new rows to database ole db command
The write new rows command will not work, VS says it executed fine, but no rows are written to the table
I'm trying to get this package to update the modified rows and write the new rows to the table
I tried a simple
insert into table(a,b)
select a,b from othertable
where a = ?
but this didn't work
I then tried the following command ( this command works if run on SQL server management studio):
Insert into mytable ( a,b)
select CB.a, CB.b
from database_A.dbo.CB CB
left join database_B.dbo.CS CS
on CB.a = CS.a
where CS.a is null and CB.a = ?
The database connection manager points to database_B
The table that I'm trying to insert the data to has a primary key constraint on a.
It's a bit annoying to have to go through this process manually
Any ideas why this isn't working?
TIA

objRS.Open strSQL1, objConn , 2 , 3 , adCmdText
If not (objRS.BOF and objRS.EOF) Then

I am writing a pgm that attaches to a SQL Server database. I have an Add stored procedure and an Update stored procedure. The two are almost identical, except for a couple parameters. However, the Add function works and the Update does not. Can anyone see why? I can't seem to find what the problem is...
This was my test:
Dim cmd As New SqlCommand("pContact_Update", cn)
'Dim cmd As New SqlCommand("pContact_Add", cn)
Try
cmd.CommandType = CommandType.StoredProcedure
cmd.Parameters.Add("@UserId", SqlDbType.VarChar).Value = UserId
cmd.Parameters.Add("@FirstName", SqlDbType.VarChar).Value = TextBox1.Text
[...etc more parameters...]
cmd.Parameters.Add("@Id", SqlDbType.VarChar).Value = ContactId
cn.Open()
cmd.ExecuteNonQuery()
Label1.Text = "done"
cn.Close()
Catch ex As Exception
Label1.Text = ex.Message
End Try
When I use the Add procedure, a record is added correctly and I receive the "done" message. When I use the Update procedure, the record is not updated, but I still receive the "done" message.
I have looked at the stored procedures and the syntax is correct according to SQL Server.
Please I would appreciate any advice...

My compiler says that the line in bold below is illegal. The error msg I'm getting is: No overload for method 'select' takes '0' arguments. How can I correct this error and execute a SELECT?

SqlDataSource2.Select ();
}
protected void SqlDataSource2_Selected(object sender, SqlDataSourceStatusEventArgs e)
{string strReadyFirstName = e.Command.Parameters["@FirstName"].Value.ToString();string strReadyLastName = e.Command.Parameters["@LastName"].Value.ToString();
}
<asp:SqlDataSource ID="SqlDataSource2" runat="server"
ConnectionString="<%$ ConnectionStrings:ConnectionString %>"

Hi there, I'm not exactly sure where to post this question, so I'll post it here.
I have 2 Windows XP machines, not part of a network domain. One of the XP machines is running SQL Server 2005 Express edition, lets call this DB machine. The other machine is just running my application - App machine. As part of my application, I want to be able to do a backup of the database.
The DB machine is also running the application. If I log into my application on the DB machine using SQL Server Authentication, and run the backup it works fine. (It's using the T-SQL BACKUP command). If it log into my application on the App machine, and try to do the backup, I'm getting an error saying that "The user is not associated with a trusted SQL connection". The same user is being used in both scenarios, and this user can update the database fine on the App machine, so it's not really a connection problem, it seems a permission problem. The SQL user I have created is a member of the db_backupoperator role for the required database.
Is anyone aware as to why I would be getting this error?

I have a script from ASP.NET application services. It can be crated using the aspnet_regsql.exe utility in the 2.0 framework. The beginning of the script contains the following:
Code Snippet SQL
DECLARE @dbname nvarchar(128)
DECLARE @dboptions nvarchar(1024)
SET @dboptions = N'/**/'
SET @dbname = N'databasename'
IF (NOT EXISTS (SELECT name
FROM master.dbo.sysdatabases
WHERE name = @dbname))
BEGIN
PRINT 'Creating the ' + @dbname + ' database...'
DECLARE @cmd nvarchar(500)
SET @cmd = 'CREATE DATABASE [' + @dbname + '] ' + @dboptions
EXEC(@cmd)
END
GO
USE [databasename]
GO
I have a database in the App_Data folder in an ASP.NET website project. It shows up in the Server Explorer. But when I run this script on that database, the output seems fine (No rows affected. (0 row(s) returned) etc) but no tables are actually created in the database I ran it on. The database connection string in the Server Explorer has AttachDbFilename and User Instance=True.
So what exactly happens when SQL Server Express executes the CREATE DATABASE and USE [databasename] in this context? Is it ignored, is there now a new database somewhere on my machine, because the script seems to run fine on SOME database, just not the one expected.
Thanks!

I have a database on a server that im trying to update using asp.net. I tested this on another server and everything worked perfectly. The test system was set up where the website is hosted. But the live system is placed on a different server than the webpage. Does that make a difference?
Test System
Client -> Website/database
Live System:
Client -> website -> database
I created a user account to use when accessing the database on the live system because i read the double hop causes problems. By using that account i can access and view the data. But whenever i update it nothing happens. NO ERROR either. It works perfectly but does nothing. Anyone have any ideas please?!?!?!

I have a page that shows current data for a customer and allows you to make changes to the data, then I have a button to push to update the system. If I hard-code in a value in place of '@Pf_Value' it will update that value, so I know my where is working, just SOMETHING missing in syntax on the set statement or something wrong on my cmd.parameters statement. Any help would be great!!Protected Sub UpdateButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles UpdateButton.Click
Dim sql As String = "update CustomerPOFlexField set [Pf_Value] = @Pf_Value where Pf_property = 'Attrib1' and Pf_CustomerNo = @CustomerNo"Dim newc As String = NewCustomer.Text

I'm using SQL Server Management Studio to do an extremely simple table update (I thought). I wish to fill a newly added table field with a value, however I didn't do this before... What I do is:
UPDATE _t_Computerhuys_MSCRM.dbo.ContactExtensionBase
SET New_Test = "Testvalue"
However then I get the errormessage:
Msg 207, Level 16, State 1, Line 2
Invalid column name 'Testvalue'.
Apparently what I see as a value is being looked at as a column name. I guess it has to do with syntax, but I can't find what's wrong. How to solve?

Here I have the following command
Dim dtNow As DateTime = DateTime.NowSqlDataSource1.UpdateCommand="Update [db] Set [LW]='TRUE', LWD=dtnow Where [PK]=@PK"What I was ttrying to accomplish was , in my grid view, when someone clicks update, it would automatically set LW to true and set LWD to today's date. No user intervention required. However, I figured the above script would not work. What would I have to do to make LWD = dtnow? I do not want to give the user the option to update anything.

Hello, I'm using a Gridview to display a list of servers. Each server has a column in a table called "Enabled." I want to create a button that is supposed to toggle the value called "Enabled." I am able to make the button either to set Enabled to true or false, but I don't know how to make it toggle. Here is the command:UpdateCommand="UPDATE [ServerStatus] SET [Enabled] = 1 WHERE [ServerName] = @ServerName" The button is a buttonfield in the gridview:<asp:ButtonField ButtonType="Button" CommandName="Update" HeaderText="Toggle" ShowHeader="True" Text="Toggle" /> Does anyone know the syntax, or a way to make the button set Enabled to true when it is false, and false when it is set to true?

I have the code as fallows to update my SQL data ;Sub Kaydet(ByVal TickerKod As String, ByVal op1 As Double, ByVal op2 As Double, ByVal op3 As Double, ByVal op4 As Double, ByVal op5 As Double, ByVal op6 As Double, ByVal op7 As Double, ByVal mov1 As Double, ByVal mov2 As Double)
'Dim nop1 As Decimal = FormatNumber(Replace(op1, ",", "."), 2)Dim mysource As New SqlDataSource
mysource.ConnectionString = ("Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|Stock.mdf;Integrated Security=True;User Instance=True")mysource.UpdateCommand = ("UPDATE StockParametre SET OPT1 = " & FormatNumber(op1, 2) & ", OPT2 = " & FormatNumber(op2, 2) & ", OPT3 = " & FormatNumber(op3, 2) & ", OPT4 = " & FormatNumber(op4, 2) & ", OPT5 = " & FormatNumber(op5, 2) & ", OPT6 = " & FormatNumber(op6, 2) & ", OPT7 = " & FormatNumber(op7, 2) & ", MOVY = " & FormatNumber(mov1, 2) & ", MOVD = " & FormatNumber(mov2, 2) & " WHERE (Stock = '" & TickerKod & "')")
mysource.Update()Response.Write(mysource.UpdateCommand & "<br>")
End Sub
When I call this code inside of Virtual Web Developer it functions perfect and updates the data..There is no problerm
But when I call it like http:// .......myip/updatedata.aspx then I have the error " System.Data.SqlClient.SqlException: Incorrect Syntax near 32
I see that 32 is the value inside the update command like SET OPT1=107,32, OPT2=25,00, ........and so on Where do I make wrong ?
Thanks

Hi here's a bit of code. What am I doing wrong here? Visual Studio isn't even accepting the Set word on line 56. It deletes it everytime. What am I doing wrong here? Why is Visual studio putting the parenthese around the table name in 55? I generated an update query for my Websitetableadapter. Here it is:
UPDATE [tblWebSite] SET [Rating] = @Rating, WHERE (([WebSiteID] = @Original_WebSiteID))
How do I use this to update the Rating column after I've done my calculation below?
1 Imports RatingsTableAdapters2 3 4 Partial Class admin_ratings5 Inherits System.Web.UI.Page6 7 Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load8 Dim I As Integer = 09 Dim J As Integer = 010 Dim Rating As Integer11 Dim Rate As Decimal12 Dim tblwebsiteAdapter As New tblWebSiteTableAdapter13 Dim tblWebsite As ratings.tblWebSiteDataTable14 tblWebsite = tblwebsiteAdapter.GetData()15 For Each tblwebsiteRow As ratings.tblWebSiteRow In tblWebsite16 Rate = 017 Dim tblLinkAdapter As New tblLinkTableAdapter18 Dim tblLink As ratings.tblLinkDataTable19 Dim tblLinkTot As ratings.tblLinkDataTable20 tblLink = tblLinkAdapter.GetSuccessfulExchanges(tblwebsiteRow.WebSiteID)21 tblLinkTot = tblLinkAdapter.GetTotalLinks(tblwebsiteRow.WebSiteID)22 For Each tbllinkRow As ratings.tblLinkRow In tblLink23 If tbllinkRow.LinkID < 1 Then24 I = 0.125 Else : I = I + 126 End If27 Next28 If I <> 0 Then29 For Each tbllinktotrow As ratings.tblLinkRow In tblLinkTot30 If tbllinktotrow.LinkID < 1 Then31 J = 0.132 Else : J = J + 133 End If34 Next35 End If36 If I <> 0 And J <> 0 Then37 38 Rate = I / J39 If Rate <= 0.3 Then40 Rate = 041 End If42 If Rate <= 0.5 Then43 Rate = 144 End If45 If Rate <= 0.65 Then46 Rate = 247 End If48 If Rate <= 0.75 Then49 Rate = 350 End If51 End If52 53 Response.Write(tblwebsiteRow.WebSiteID & " " & tblwebsiteRow.SiteURL & " Rating: " & Rate & "54 I = 055 J = 056 Update(tblWebsite)57 Rating = Rate58 where(tblwebsiteRow.WebSiteID <> 0)59 Next60 End Sub61 End Class
