Dataset updating database

NVar Char, 1073741823, "Description")) Dim nwind DS As Data Set = New Data Set() nwind DA. Hope this helps Jay "Cor" Hi Jay B, I could not find that text. Sql Exception: String or binary data would be truncated. Sceppa's book explains it more detail then the above statement. 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. 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. Fill(nwind DS, "Categories") Dim dt Table As Data Table Dim dr Row As Data Row dt Table = nwind DS. New Row() dr Row("Category Name") = "New Category Name" dr Row("Description") = "New Description" dt Table. (I even have searched for "using" on that page) Did you send maybe the wrong link? Close() End Sub Hi Tom, Read it to the end before you become afraid If you do it nice you have to make an Insert, an Update, and a Delete command. Close() End Sub Cor, Thanks so much for taking the time to show me how to make this work. I copied/pasted your code into my ide, made a few minor syntax fixes and got the following error : Unhandled Exception: System. 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.

to retrieve all of a table takes time, especially if there are many rows in the table.

Dim query String As String = _ "SELECT Customer ID, Company Name FROM dbo. // Assumes that order Connection is a valid Ole Db Connection object. Before the tables in the are filled with the data in the chaptered columns, a relation is created between the parent and child tables of the hierarchical rowset by adding an integer column to both the parent and child table, setting the parent column to auto-increment, and creating a , only that table will be filled.

Customers" Dim adapter As Sql Data Adapter = New Sql Data Adapter( _ query String, connection) Dim customers As Data Set = New Data Set adapter. Sql Data Adapter cust Adapter = new Sql Data Adapter( "SELECT * FROM dbo. An auto-incrementing integer column will still be added to the table, but no child table will be created or filled, and no relation will be created.

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.

I concluded that removing it seemed the most logical). (But I never use that, I bring it into if it is complex, I hate SQL) I added also the test for if the datase has changes (here always of course), than it skips the update if that is not, little bit nicer. I concluded that removing it seemed the most logical).
