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), "'", "`")

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

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'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?

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?

I'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.

I have a table in Access with two key fields (let's call them Item and Cust). These key fields *combined* are the primary key. So each record must have a unique Item and User combination. It can have a duplicate Item with other records, and a duplicate Cust with other records, but not a duplicate of both. Because my "primary key" is a combination of two fields, I can't make a primary key on the table in Access (it only supports one field as a primary key).
I have another table in SQLServer which also has Item and Cust, but in addition, is has several descriptive fields that give more details about the Item and Cust. I'm trying to use ADO.NET to bring in that SQL Server table and UPDATE some matching fields in Access with the descriptive fields. [Code]

This is for visual basic 2008 express edition.Ive been trying to update records from the table of my memrec.dbml and dbase1DataSet.xsd in the visual basic environment.Im not using any sql database server but Im just using the built-in sql server within the visual basic 2008 express.I was able to add records and retreived it to display in the textboxes.My 1st block of codes I used to edit records has an error message which says:NotSupportedException was unhandled - Sql server does not handle comparison of NText, Text, Xml, or Image data types.
My 2nd block of codes I tried to used doesn't have any error and it ables to change the records while at runtime but when you exit the program the changes was not save at all cause when you run it again the records that were changed during runtime goes back to its original records.Let me take you a look at the two blocks of codes
[Code]...
Questions:
1.What do you see as possible cause for having an error in 1st block of codes?What's the remedy for that?
2.For the 2nd block of codes,what is the valid update command to be added in the line in order to save the changes not just during runtime but until you exit the program and run it again?

I'm struggling to work with data in VB 2008, and find it extremely complicated! At first I couldn't even get a database to load, as VB 2008 kept complaining it was created with an older Jet engine.OK, I converted it to a newer Access format that VB 2008 finally accepted.
In trying to find out why changes weren't saved, I found a common problem was VB 2008 wiping out changes.OK I have told the compiler not to copy the older database file back over but to copy newer.Updates then supposedly happened --- no errors were reported --- but the changes were still not saved.It appears the update method didn't exist in the datatableadapter, but I got no error messages about that.
No update done.
I've used the tools to configure the dataset and datatableadapter.Automatic generation of methods like update, add new, delete, etc. were supposedly done.Now, when trapping the error, I'm told the update method isn't a valid one.I found little information on that. It suggested primary keys could be a cause, but adding or deleting a primary key has no effect.I can see the fill method, and it works fine.I can't see the update method. (Apparently it is in SQL which I don't know anyway.)

My users are getting this error when trying to update the database:
"Concurrency violation: UpdateCommand affected 0 of the expected 1 records"
All the users are doing is clicking a button which updates a record.No two users are updating the same record or even within the same column. They could be updating within the same row but still not the same record.It seems to be happening when the program is open for a little while and they come back and try to update the database through the program. I have read a little bit about this error but none seem to lead to a clear solution.It seems like the database connection is timing out due to inactivity?Here is my update command:
