Dataset updating database

Hi, I am trying to insert a row into the Categories Table in Nothwinds database in MSDE. Now it appears that it is at least trying to process an Insert. Now it appears that it is at least trying to process an Insert.

Modified, as that is how it knows to use the Insert Command, Delete Command, or Update Command respectively. Add followed by Accept Changes causes nothing to occur on your database. Open() Dim Sql Insert Command1 As Sql Command = New Sql Command() Sql Insert Command1. Open() Dim Sql Insert Command1 As Sql Command = New Sql Command() Sql Insert Command1.

Accept Changes on each row that it processes, so you don't need to call Accept Changes after calling Data Adapter. Command Text = "INSERT INTO Categories (Category Name, Description) VALUES (@Category Name, @Description)" Sql Insert Command1. I basically copy and pasted generated code for this fragment. Tom ==== Sub Main() Dim nwind Conn As Sql Connection = New Sql Connection ("Data Source=COL-TP5170-LT1\VSdot NET; Integrated Security=SSPI; Initial Catalog=Northwind;") Dim nwind DA As Sql Data Adapter = New Sql Data Adapter ("SELECT Category ID, Category Name, Description FROM Categories", nwind Conn) nwind Conn.

The following section will show you how to test updating, inserting, and deleting the data.

NET - Core Reference" from MS Press covers this plus a plethora of other items about ADO. Using the Debugger, it appears the Data Set loads correctly, the Data Row is populated correctly, and the new row is added to the Data Set. Open() Dim Sql Insert Command1 As Sql Command = New Sql Command() Sql Insert Command1. Invalid Operation Exception' occurred in dll Additional information: Update requires a valid Insert Command when passed Data Row collection with new rows." Do you see anything wrong with the Insert?

I am able to manually insert it using a query tool. Thanks in advance, Tom ====== Sub Main() Dim nwind Conn As Sql Connection = New Sql Connection ("Data Source=COL-TP5170-LT1\VSdot NET; Integrated Security=SSPI; Initial Catalog=Northwind;") Dim nwind DA As Sql Data Adapter = New Sql Data Adapter ("SELECT Category ID, Category Name, Description FROM Categories", nwind Conn) nwind Conn.

Command Text = "INSERT INTO Categories (Category Name, Description) VALUES (@Category Name, @Description)" Sql Insert Command1.

Here is another page not write what you say, but what I think you mix up. Cor Cor, See: section close to the middle that starts "When using Update, the order of execution is as follows". NVar Char, 1073741823, "Description")) ' Dim nwind DS As Data Set = New Data Set() nwind DA. That you can do using the designer that makes it and then copy and paste it. I was changing little things, but after all I have changed all your code, not because it was fault, but that was easier to show, look to it as an alternative. NVar Char, 1073741823, "Description")) ' Dim nwind DS As Data Set = New Data Set() nwind DA.
