Sql - Can't Get DeleteCommand To Work In ASP.net 4.0

Calling InsertCommand In Vbscript Instead Of ASP?
Jan 26, 2009I have a DetailsView that I am using to insert an enrollment form into the database. Currently every functions fine, with one exception. Since there is a terms and agreement checkbox at the bottom of the form that I cannot validate using the existing validation controls, I'm trying to handle this in the VBScript.The problem is that the InsertCommand in my ASP executes before the Button_Click sub does, so the form is submitted before the checkbox validates. Can someone tell me how to move the InsertCommand from the ASP to the code file so that I can make sure it doesn't execute until AFTER my button validation? Here is my code:

Jul 15, 2009In my form, there is a (design time) dataadapter. This adapter has got Insert, Update, Delete and Select commands. When the InsertCommand is executed, the data in the form are inserted (and saved) to the database.
The InsertCommand has a parameter RETURN_VALUE. The value of the parameter can be read by the follwoing code.
pDataAdapter.InsertCommand.Parameters("RETURN_VALUE").value
I want to assign the above value to another field in the dataset (say, SubscriptionNo) I use the following
pPKValue = pDataAdapter.InsertCommand.Parameters("RETURN_VALUE").value
pDataSet.Tables(pDataSetTable).Rows(0).BeginEdit()
[CODE]...
But, when I assigned the pPKValue, it raises the error, "Column SubscriberNo is Read-Only". How to rectify it? I like to set this as "NON Read-only" temporarily and after updating, again set to read-only.

VS 2008 - Update Requires A Valid InsertCommand
Jun 30, 2009I'm trying to get a database to add a new row on this form. The user types a word into a text box, clicks save, and it should update the database. The table is called "text" for now, it's an Access DB, and it has two rows: ID, and userText. [Code]
I get the error at the da.Update line when I click Save. The full error is "Update requires a valid InsertCommand when passed DataRow collection with new rows." I'm not sure if I have to add an INSERT command somehow or if something in the code needs changing. If I add this line to the Save routine, I get an "Syntax error in INSERT INTO command": Dim cb As New OleDb.OleDbCommandBuilder(da)
I don't know if I should leave that out or keep it in since both give me errors.

I would greatly appreciate it if someone could point out the flaw in my code and how to correct it.

View 9 RepliesInvalidOperationException : Update Requires A Valid InsertCommand When Passed DataRow Collection With New Rows?
Jan 8, 2010This was working on the last test, now it's throwing an InvalidOperationException saying Update requires a valid InsertCommand when passed DataRow collection with new rows. No change in this
Dim NewRowB as DataRow=dsBatch.Tables("Batch").NewRow
dsBatch.Tables("Batch").Rows.Add(NewRowB
daBatch.Update(dsBatch,"Batch")
What *has* changed is that I'm trying to fix the same error that's occurring on a different dataset in a different form. This should add a blank record to the dataset, then update the database. The blank fields allow nulls. The reason for this (and there may be another way to do this-I'm helping a novice fix up his code and, since this has been working, I haven't yet really looked at it) is to obtain the correct value for an identity field. We've found that when the row is added to the dataset, if it doesn't currently contain any rows, the identity value is set to zero-but when the database is updated, it gets a different value (because previously inserted rows have been deleted). So we update the database then retrieve the correct identity value before continuing.As I said, this was working fine-until I started working on the same problem occurring in a different dataset. So why would that affect this dataset?

But the strange thing is that I have similar code on another form and it works great. The only difference is the database table is different. I verified both tables and they look identical, as far as settings. I have verified that _Non_MS_Office_Licenses has a primary key that is unique. Looking in dataset manager I see the query for fillBy() is fine and it has all the insert and update stuff. At the end when it verifies it says all is verified when I configure the dataset
Dim row = FrmApp.Non_MS_Office_LicensesBindingSource.Current
row("Primary User") = Replace(CStr(TxtUserid.Text), "'", "`")
row("Staff Last Name") = Replace(CStr(TxtLastName.Text), "'", "`")

UpdateCommand Affected 0 Of Expected 1 Records
Aug 8, 2009I've got a simple mdb database set up in Visual Basic Express Edition (winforms) and I'm trying to update data from a datagridview to a database. I've databinded the textboxes to the columns I want in the datagridview and this works great. After some struggling, I've finally managed to have the values updated in every row of the database. But, trying to modify a newly created record throws this error:
"Concurrency violation: the UpdateCommand affected 0 of the expected 1 records"
I mean, it seems as though the error only happens with newly created rows. Because closing the application and reopening it immediatly, I'm allowed to update the values of the cells.
I also noticed that the ID of the row is set to "-1" when I've just created a new row. The other rows don't have a negative number for ID. Could this be the cause? Seems as though the row isn't really updated to the database.
So this is the code for the AddRow button
Dim newRow As MusicDBDataSet.SongsRow
newRow = MusicDBDataSet.Songs.NewSongsRow()
newRow.Name = txtBoxNewName.Text
newRow.Genre = txtBoxNewGenre.Text
newRow.Rhytm = txtBoxNewRhytm.Text
[Code] .....
But thinking about it, the textboxes used to update the values of the newly created row are databinded to the database or tableadapter itself right? Could it be that the UpdateCommand fails because the row hasn't really been created properly yet?

Dataadapter, Update, Updatecommand Dataset Stuff?
Jan 25, 2007I'm having trouble updating a sql server database with a dataset using a dataadapter. I have used the dataadapter with success in the past when adding new rows, using a single table, and just calling the dataadapter.update command.However, I am now running into a more complex scenario and I need to use dataadapter.UpdateCommand method and I'm having lots of problems.
The sql statement that I'm using to fill the dataset looks like this: "Select [Order Details].ProductID, [Order Details].UnitPrice, [Order Details].Quantity, [Order Details].Discount, Products.ProductName From [Order Details] INNER JOIN Products ON [Order Details].ProductID = Products.ProductID Where OrderID='" & strOrderID & "'", sqlConn"
This is pulling the data from 2 different tables (Order Details and Products) and then joining them and filling the dataset, and I am seeing the exact results I want. I am then binding the dataset to a datagrid control that allows the user the option to edit the datagrid, which in turn updates the dataset.
So that being said how do I get the updated dataset back into the database? I tried using dataadapter.update but it informed me that I now need to use dataadapter.UpdateCommand. Ok, so I've looked up how to use UpdateCommand but I cannot for the life of me figure out how to set up the right sql command statement. Part of what has me confused is the UpdateCommand examples I have seen are working with a specific row and updating that rows data. I can get that to work but I want all changes to the dataset to persist and update to the database when the user is done working on the datagrid.
Also, the examples shown set up command parameters but again, this is only confusing me because I just want to send the whole dataset back to the database. It seems like the parameters are saying "Ok, this specific row in this specific dataset.table, update these specific fields in this specific database". I'm not sure how to accomplish that when working with a datagrid.
