VS 02/03 RETURN_VALUE In DataAdapter.InsertCommand
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.
VS 2008 InsertCommand - Column 'Contact_2' Cannot Be Null
Mar 8, 2012I 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)"

VS 2008 Datatable - Datagridview Using A Bindingsource And Dataadapter
Dec 8, 2009I populate a datagridview using a bindingsource and dataadapter. So I join 3 tables in the view to get the data i need.
so I have my view as a child table in my dataset. and a table called classes which is the parent table. So when I select a Class(class 1A for example), my datagridview displays the pupils in that class.
Now i need to add another relationship in the dataset. so when I select a day in a monthcalendar, I need to add 5 checkbox columns for each day to my datagridview. Should I add these 5 columns to my datatable? i'm not sure what the best way is.
Then for each day I tick I have to save to my pupil_job_day table. I will save the peoleid,their accountid and the date. please help me

View 7 RepliesVS 2008 DataAdapter.Update - Field Names Have Numbers?
Nov 4, 2009I posted in the Database development forum, but no bites. I have field names in my Access table which have a number as the first character (i.e. "2x2"). Evidently, the DataAdapter doesn't like this. I'm able to view the data in a DataGridView, but I get an exception when I use DataAdapter.Update.
Can I modify my sql statement to make the command builder work or do I have rename the fields?
For example:
"SELECT [2x2] as twoBytwo..."
Changing the names of the fields would be a huge pain-in-the-arse!

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:

Oct 18, 2011I'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.
View 9 RepliesInvalidOperationException : Update Requires A Valid InsertCommand When Passed DataRow Collection With New Rows?

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?

Nov 30, 2010This 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.
DataAdapter Does Not Update A Record?

Everything is fine, just one line fails and is driving me nuts Here is the 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?
