Update Requires A Valid InsertCommand When Passed DataRow Collection With New Rows?

Oct 18, 2011

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.

InvalidOperationException : Update Requires A Valid InsertCommand When Passed DataRow Collection With New Rows?

Jan 8, 2010

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?

Update Requires A Valid UpdateCommand When Passed DataRow Collection With Modified Rows

Jul 27, 2007

I have looked at multiple posts regarding this issue, but can't seem to find a solution. To keep it simple I have an Access database with a single table. It does have a field as a primary key. When I click the save icon on the Binding Navigator I get this error having to do with the following code:

Me.Validate()
Me.TitlesBindingSource.EndEdit()
Me.TitlesTableAdapter.Update(Me.VFCurvesDataSet.Titles)

I cannot set the Refresh the Data Table check box in Advanced Options of the TableAdapter Configuration Wizard as it is grayed out. Once again, I have a primary key.

The posts I have reviewed indicate that an UpdateCommand needs to be created, but I can't understand how it should be done. W

DataRow Collection - Update Requires Valid Delete Command?

May 1, 2010

I'm going through a book which is teaching me some basic coding principles of the language. The current section is detailing how to set up a master child form using two tables linked with a foreign key. The master table is displayed as a number of text boxes, and below is a grid with the child table which shows related records to whatever master record you happen to be checking out. At the top of the screen are the default navigation controls that are added with the grid. The master table is named Person and the child table Book. They are linked using a foreign key and have cascade set up on them.

The book informed me of the code required under the save icon on the navigation control so that when it is clicked both tables will be updated as required. It is as follows:
If Validate() Then
'Make sure editing has completed on both master and child tables
Me.BookBindingSource.EndEdit()
Me.PersonBindingSource.EndEdit()
[Code] .....

I have double checked that the code matches that shown, so this should in theory work fine. But if I manually delete a record from the Book (child table) grid and then click the Save icon on the navigation bar it comes up with the error "Update Requires A Valid DeleteCommand when passed DataRow collection with deleted rows".

Why changes made are not permanently saved to the database? I gather that it's using a "copy" of the data in the database but how do I get the code/form to make changes to the actual underlying database records as well as just the copy? I find this system very unusual, if someone deletes a record in the application why would anyone want this to be just done temporarily?

VS 2008 - Update Requires A Valid InsertCommand

Jun 30, 2009

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.

Update Requires Valid UpdateCommand?

May 10, 2011

Update requires valid UpdateCommand passed DataRow collection modified rows. When I run the following code. 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), "'", "`")
row("Staff First Name") = Replace(CStr(TxtFirstName.Text), "'", "`")

Test If A Collection Of DataRow() HasChanges

Apr 12, 2012

I use the Select method on my typed dataset to return an Array of DataRows.' get settings for the DataGridView from the dataset and be sure to sort the returned rows by the display index

[CODE]................

Is there a way to test if any of the DataRows in the Array have changes? I already know about DataSet.HasChanges method, but in my procedure I want to run some code on the DataRow() Array only if one of the rows have changes. In my example below I get a subset of DataRows from my DataSet. If only one DataRow in the DataSet has been modified my For Each...Loop will run 10 times.

For i As Integer = 0 To 10 ' get settings for the DataGridView from the dataset and be sure to sort the returned rows by the display index

[CODE]...................

if rows where added to or deleted from the dataset then the DisplayIndexes need to be reassigned
If Me.ds.HasChanges Then

[CODE]........

I only want it to run 1 time. For example,

For i As Integer = 0 To 10 ' get settings for the DataGridView from the dataset and be sure to sort the returned rows by the display index

Can anyone tell me why "Rows cannot be programmatically added to the DataGridView's rows collection when the control is data-bound." I keep getting an error "Invalid Operation Exception was Unhandled" error. All I am attempting to do is allow the user to select products from a list(or a second datagridview) and have it added to the datagridview so they do not have to type in every cell since the other cells are not visible because they do not purtain to their needs. Plus they will be able to save all items at the same time.

Update Access DB With Passed In Values?

Mar 11, 2010

I am currently working on a project that requires an update within an Access Database. There are photo folders, and the user defines the path name via a dialog box. That path name is stored to a string value, and through OleDBReader, the actual name of the photo (from another column in the database) is stored to another string value. Anyway, I have tried a number of methods to update, and nothing is working, here is my code from the OleDBReader on, and the procedure designed to do the update. (note that TargetID represents the primary key of the access DB.. this is why I pass that value in because I can use the Rows.Find(PK) method.. When I use a simpler updating method, I get an error saying I do not have a valid update command). OK Here is the code:

Dim photoSQL As String = "SELECT * FROM PotentialTarget"
Dim oleDbCommand As OleDbCommand = New OleDbCommand(photoSQL, tableConn)
Dim oleDbDataReader As OleDbDataReader = oleDbCommand.ExecuteReader()

The code works fine.But in the above code as you can see that i am printing the each rows content of the datatable one by one and after printing all the contents of a single row i am looping the code again for printing each and every row present in the datatable. So i want to know that inspite of printing each and every data present in the row of the datatable,is it possible to print the entire datarow at a time and then loop through all the rows present in the datatable?

Update A DataRow Immediately After Inserting It ?

Sep 20, 2011

I have an OleDBDataAdapter which I am using to communicating with an Access database. I have generated a SELECT command with parameters, and used this to generate a DataSet.I have then used the OleDbCommandBuilder to generate the UPDATE and INSERT commands. I can use this successfully to fetch data and then update it.

Next I have created a I have a DataRow using DataSet.Tables.NewRow which I have populated.I have then used my DataAdapter to insert this record.This works just find. I would like to now update this DataRow.Can I refresh this DataRow so that it populates the fields such as the autonumber field and the automatically populated timestamp? I could select it again but I don't know the autonumber. Is there not some way that I can get the existing DataRow to synchronise with the new row?
