VS 02/03 RETURN_VALUE In DataAdapter.InsertCommand
Jul 15, 2009
In 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.

I 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:

At the following cmd.ExecuteNonQuery() line, I get the following error message: [code] I have followed the example at page [code] as closely as possible, but it does not work.Additionally, I am not sure of the syntax for the length (64) that I have for the BigInt or if it should even have a length.All of the examples that I have found in MSDN uses only parameters with character rather than numberic type.

Take a look at this code. The OLEDB command builder does not create insert command nor delete or update commands.

I'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 am connected to a MYSQL database and the following Insertcommand works fine:
InsertCommand="INSERT INTO suppliers (Supplier) VALUES (?Supplier)"
Now when I want the option of updating all the columns it keeps saying "Column 'Contact_2' cannot be null" or contact_1, so all the fields need something and not all suppliers of course have two numbers. What am I doing wrong? here is the
InsertCommand="INSERT INTO suppliers (Supplier, Contact_1, Contact_2) VALUES (?Supplier, ?Contact_1, ?Contact_2)"

I'm getting an error when the 'insertcommand' is executed telling me that I'm missing the parameters for the stored procedure. Do I need to put the parameter names in the Sql statement after the procedure as if I were calling it in SQL? I saw an example online that just added the parameters like I have here, but this doesn't work? I also put the sql state for the stored procedure below the 'AddRepair Sub'
Public Shared Sub AddRepair(ByVal repair As ClubRepair)
Dim conn As SqlConnection = ClubRentalsDB.getconnection
Dim insertcommand As New SqlCommand("AddRepair", conn)

I'm still pretty new at .Net and database coding, and am working on a small program that is generating an error and I'm not sure how to resolve it.[code]The following statement is giving me the error below: m_DA.Update(m_DataTable)"Update requires a valid InsertCommand when passed DataRow collection with new Rows".I know the answer is going to be very simple, but I'm at a loss. I would greatly appreciate it if someone could point out the flaw in my code and how to correct it. And yes, I have done fairly extensive searching on this error, but none of them give any idea how to fix it, they just hint around at what's wrong.

This 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?

This should be a fairly simple one. I am creating a dataset which will contain a description field which I would like to sort by. The reason I want to sort the dataadapter and not in my SQL is that I am already ordering by the results that have a particular value.My SQL looks like this:
SELECT pif_desc, pif_fund, psf_end, (CASE WHEN SUM(pmi_units) IS Null THEN 0 ELSE SUM(pmi_units) END) As fundunits
FROM tbl_mem INNER JOIN tbl_sfunds[code]....
I want to sort the datarows is ds.tables(0) by pif_desc but still have the rows with fundunits > 0 listed first. how I can achieve the correct ordering.

I have been researching all that is related to DataSources, DataReaders, DataAdapters, etc, with an Access 2010 DB bound to a DataGridView.
Everything is fine, just one line fails and is driving me nuts Here is the code:
[Code]...
The line that fails, actually updates my database, but somehow, the update is not performed on the line that belongs to the first row of the grid. What is more, if I change the value manually, the same update method works fine. What is going on here?

I'm trying to create a form that uses controls that are bound at runtime. All the data objects are declared at the form level. The Select statement includes the two fields that make up the PK form the table. The Owing_Company data displays in the bound control. I can change the text and in Save_Click the RowState is Modified and Row!Owning_company has the changed data. DsForm.HasChanges is False. A simple call in Save_Click daForm.Update(dsForm) does not change the DB. If I update the Row!Owning_Company in code dsForm.HasChanges is now true and daForm.Update changes the data. What am I missing that allows changes made via the bound control to modify the DataSet?
