InsertCommand , UpdateCommand , and DeleteCommand properties of the DataAdapter are Command objects that manage updates to the data in the data source according to modifications made to the data in the DataSet.
Dim adapter As New SqlDataAdapter() adapter.InsertCommand = New SqlCommand(insertSql, connection)
SqlDataAdapter adapter = new SqlDataAdapter(); adapter.InsertCommand = new SqlCommand(insertSql, connection);
Dim adapter As New SqlDataAdapter() adapter.UpdateCommand = New SqlCommand(updateSql, connection)
SqlDataAdapter adapter = new SqlDataAdapter(); adapter.UpdateCommand = new SqlCommand(updateSql, connection);
Dim adapter As New SqlDataAdapter() adapter.DeleteCommand = New SqlCommand(deleteSql, connection)
