You use Microsoft .NET Framework 4 to develop an application that connects to a Microsoft SQL
Server 2008 database You populate a SqlDataAdapter by using the following code. (Line numbers are
included for reference only.)
01 Dim dataAdapterl As SqlDataAdapter = New SqlDataAdapter(
“SELECT * FROM [BlogEntries] ” &_
“ORDER BY CreationDate”, connection)

02 cindBuilder = New SqlCoittnandBuilder (dataAdapterl)
03 dataAdapter1.Fill(BlogEntryDataSet, “BlogEntries”) 04
05 connection.Close()
You need to update the blog owner for all BlogEntry records.
Which code segment should you insert at line 04?

A.
Dim dataAdapter2 As SqlDataAdapter = New SqlDataAdapter(
dataAdapterl.UpdateCommand)
dataAdapter2.Fill(BlogEntryDataSet, “BlogEntries”)

B.
For Each row As DataRow In BlogEntryDataSet.Tables(_
“BlogEntries”).Rows row.Item(“BlogOwner”) = “New Owner” Next
dataAdapterl.Update(BlogEntryDataSet, “BlogEntries”)

C.
For Each row As DataRow In BlogEntryDataSet.Tables(
“BlogEntries”).Rows
row.Item(“BlogOwner”) = “New Owner”
Next
dataAdapterl.Fill(BlogEntryDataSet, “BlogEntries”)

D.
Dim dataAdapter2 As SqlDataAdapter = New SqlDataAdapter(
“UPDATE [BlogEntries] SET [BlogOwner = ‘New ‘Owner’]”,
connection)
dataAdapter2.Update(BlogEntryDataSet, “BlogEntries”)

Explanation:
SqlDataAdapter.Update() – Calls the respective INSERT, UPDATE, or DELETE statements for each
inserted, updated, or deleted row in the System.Data.DataSet with the specified
System.Data.DataTable name.
