use where id = 'whatever one you want to update'
|
|
|
|
|
well, when I am putting WHERE [id]=@name I get this error:
Conversion failed when converting the nvarchar value 'edenss' to data type int.
and when I am putting WHERE [id]=@id I get update of all the fields where the ID is existing.
|
|
|
|
|
where id = @id should work
you need to make sure it is jus selecting the one id
can you post your whole code
|
|
|
|
|
<asp:sqldatasource id="SqlDataSource1" runat="server" connectionstring="">]]>"
SelectCommand="SELECT * FROM [tblname]" InsertCommand="INSERT INTO tblname(name) VALUES (@name)"
UpdateCommand="UPDATE [tblname] SET name=@name WHERE id = @id">
<insertparameters>
<asp:parameter name="name">
<asp:parameter name="name">
|
|
|
|
|
where is @id declared, what is it? textbox value, hardcoded value?
|
|
|
|
|
id is just a field in the table, it's of type identity and is incremented for one with adding one more record in the table, something like autonumber in MS Access. With @id I think it should update the field with the current id is open. As I told you, I am a beginner so maybe I did some mistake, and any help will be appreciated. Thanks ahead

let me give you an example of an update statement
SqlCommand sqlcommand = new SqlCommand("as_insert_command",
sqlConn);
sqlcommand.CommandType = CommandType.StoredProcedure;
SqlParameter para1= sqlcommand.Parameters.Add("@id",
SqlDbType.Int, 4);
para1.Value = textboxid;
see the @id is set against a textbox id
so if someone enters a value in the textbox, that value will update the id
is this what you are trying to achieve
the id needs to be set somewhere this is why i am confused
|
|
|
|
|
I see...but the thing is that I am not using any textboxes, I am just attaching a connection to the database with the DetailsView, and cause in my test database, there is only two fields: ID and Name, that's why I put WHERE id=@id. So if I want to make a statement for StoredProcedure for updating the fields, how should I declared?? Let's say, I have just two fields, like in my test DB. Thanks very much!!

I really don't understand what you are trying to achieve sorry
|
|
|
|

OK  . Thx for your help anyway, and sorry for taking your time. Have a nice day!

hi, i'm begginer also just like u. i don't know if my answer can help u, but here goes.
where id=@id
when u use this, all the id in the table will be update. u have to put a text box where u can put which id u want to update.
Dim sql = "UPDATE table1 SET name = @name WHERE id = @id"
conn = New SqlConnection(ConfigurationSettings.AppSettings("strConn"))
comm = New SqlCommand(sql, conn)
comm.Parameters.Add(New SqlParameter("@id", SqlDbType.Char, 50))
comm.Parameters("@id").Value = textbox1.Text.Trim
update the table that u want where the id that u choose r from textbox1. when u set the value for id is from the textbox, then it will only update name where the id is from the textbox that u enter.
i'm doing the same project just like yours.
hope it will help u.

No idea why it is setting all other controls to disabled state.How ever if you dont want the validation conrol go get in to action when the cancel button is clicked then set the CausesValidation property of the cancel button to false.
Thanks

Its very simple... just add a button column with command name="select"
and then write ur code in the selected index changed event...
When you fail to plan, you are planning to fail.
