Aug 8, 2011

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

Calling InsertCommand In Vbscript Instead Of ASP?

Jan 26, 2009

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:

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.

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.

VS 2008 InsertCommand - Column 'Contact_2' Cannot Be Null

Mar 8, 2012

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)"

Sql - Parameterized Store Procedures - Getting An Error When The 'insertcommand' Is Executed

May 25, 2011

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

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?

The form is an About Us form so has nothing on it only a text box and a OK button.

Why won't the button close the form? I'm puzzled, I tried another button just in case with the same result. UPDATE: I set a break point on Me.Close() and it isn't reaching it when I click the button, I created a new button and the same thing happened.

If Statement Doesn't Return

Mar 22, 2012

Am I just being blind or does this If statement genuinely not do what it's meant to.[code]This displays the message box even though textSample is one of the letters. In my eyes that If statement should see that textSample is one of those letters and skip it, whereas if it was Z it would "Not" be equal to any of those and would therefore show the message box.
