Updating dataset in vb net

Dim ds As New Data Set Dim dt As Data Table Dim dr As Data Row Dim cl As Data Column Dim i As Integer dt = New Data Table() cl = New Data Column( "the Column", Type.

You can quickly serialize a Data Set to XML by calling the Write XML method.

To insert, update, and delete data using a Data Adapter, you create an Ole Db Command object with INSERT, UPDATE, and DELETE statements and set the Insert Command, Update Command, and Delete Command properties of the data adapter to Ole Db Command.

You can avoid building Command objects manually by using Command Builder.

I am pulling data from 1 database(QAD) into a Data Set. Open() sql String = "" sql String = "SELECT Inventory_Number, Status, drwg_size FROM Inventory_Test" Inventory_Test = New Sql Data Adapter(sql String, obj Conn) QADStatus = New Data Set QAD. Fill(QADStatus, "Inventory_Test") Dim QADtable As Data Column Dim Inven Table As Data Column Dim data_relation As Data Relation QADtable = QADStatus.

I need help trying to Update a table in a different database(Inventory_Test) with the data collected in the Data Set.

Here is how i pull in the data from the databases to the Data Sets: Imports System Imports System.

In addition to being reliable and easy to use, Data Set supports both a hierarchical view of the data as XML and a relational view that you can manage after your program disconnects.

Load Dim connection String As String connection String = "My connection to QAD Database" Dim obj Conn As New Sql Connection(connection String) obj Conn. Columns("Inventory_Number") data_relation = New Data Relation("QADto Inventory_Test", QADtable, Inven Table) QADStatus. I know to first research before posting a question...

Data Source = QADStatus End Sub Private Sub Button1_Click(sender As System. Would you like a screen shot on my HISTORY/Cookies...

After that I called the Data Adapter's Update method to save the changes to the database table.

A Data Set object usually corresponds to a real database table or view, but Data Set is a disconnected view of the database. NET creates a Data Set, there is no need for an active connection to the database, which helps in scalability because the program only has to connect with a database server for microseconds when reading or writing.
