Property Value

Type: System.Data.Common.DbCommand

An IDbCommand used during Update to delete records in the data source for deleted rows in the data set.

During Update, if this property is not set and primary key information is present in the DataSet, the DeleteCommand is automatically generated.

The following example creates the derived class OleDbDataAdapter and sets some of its properties.

Public Shared Function CreateCustomerAdapter( _
    connection As OleDbConnection) As OleDbDataAdapter 

    Dim dataAdapter As OleDbDataAdapter = New OleDbDataAdapter()
    Dim command As OleDbCommand
    Dim parameter As OleDbParameter

    ' Create the SelectCommand.
    command = New OleDbCommand("SELECT CustomerID FROM Customers " & _
        "WHERE Country = ? AND City = ?", connection)

    command.Parameters.Add("Country", OleDbType.VarChar, 15)
    command.Parameters.Add("City", OleDbType.VarChar, 15)

    dataAdapter.SelectCommand = command

    ' Create the DeleteCommand.
    command = New OleDbCommand( _
        "DELETE * FROM Customers WHERE CustomerID = ?", _
        connection)

    parameter = command.Parameters.Add( _
        "CustomerID", OleDbType.Char, 5, "CustomerID")
    parameter.SourceVersion = DataRowVersion.Original

    dataAdapter.DeleteCommand = command

    Return dataAdapter
End Function
