You can create your own unique views of a database using Data Set. Relate Data Table objects to each other with Data Relation objects. The syntax doesn't require it, but you will normally provide the name of the Data Table to load the data into. To String) Next i Dim connection String As String = "Data Source=MUKUNTUWEAP;" & "Initial Catalog=Booze;" & "Integrated Security=True" Dim cn As New Sql Connection(connection String) Dim command Wrapper As Sql Command = New Sql Command("SELECT * FROM RECIPES", cn) Dim data Adapter As Sql Data Adapter = New Sql Data Adapter Dim my Data Set As Data Set = New Data Set data Adapter. Fill(my Data Set, "Recipes") The Data Set can then be treated as a database in your program code.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.The Find method returns the row with Customer Id = Tst ID.

Data Relation Public Class Form1 Private QAD As Sql Data Adapter Private Inventory_Test As Sql Data Adapter Private QADStatus As Data Set Private Sub Form1_Load(By Val sender As System. Open() Dim sql String As String sql String = "" sql String = "SELECT PT_Part, PT_STATUS, PT_DRWG_SIZE FROM PT_MSTR" QAD = New Sql Data Adapter(sql String, obj Conn) connection String = "" connection String = "My Connection to Inventory_Test Database" obj Conn = New Sql Connection(connection String) obj Conn. I just need to know how to take the data from the Data Set(QADStatus) into Database2(PT_MSTR_TEMP). Listing 5-50 deletes the row with the value Tst ID.As you can see from the code, I called the Find method to find the row and called the Delete method of the Data Row.The way the architecture works with the Data Adapter is that you can make any changes you want to the filled Data Set, and it won't affect the database until you call the Update method.

When Update is called, the Data Adapter will attempt to execute each query (UPDATE, INSERT, DELETE) on every row of the Data Set that has been updated, inserted, and deleted.

As you saw in the Data Table, Data Row, and Data Column sections at the beginning of this article, you can use the Delete method of a Data Row to delete a row.
