You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create an application.
The application connects to a Microsoft SQL Server database.
The application uses a DataTable named OrderDetailTable that has the following columns:
-ID
-OrderID
-ProductID
-Quantity
-LineTotal
Some records contain a null value in the LineTotal field and 0 in the Quantity field. You write the following code segment. (Line numbers are included for reference only.)
01 DataColumn column = new DataColumn("UnitPrice", typeof(double));
02 ...
03 OrderDetailTable.Columns.Add(column);
You need to add a calculated DataColumn named UnitPrice to the OrderDetailTable object.
You also need to ensure that UnitPrice is set to 0 when it cannot be calculated.
Which code segment should you insert at line 02?

• A.  column.Expression = "iif(Quantity > 0, LineTotal/Quantity, 0)";
• B.  column.Expression = "if(Quantity > 0, LineTotal/Quantity, 0)";
• C.  column.Expression = "LineTotal/ISNULL(Quantity, 1)";
• D.  column.Expression = "LineTotal/Quantity";

You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create an application.
The application connects to a Microsoft SQL Server 2008 database.
You need to ensure that the application calls a stored procedure that accepts a table-valued parameter.
You create a SqlParameter object. What should you do next?

• A.  Set the SqlDbType of SqlParameter to Structured. Set the TypeName of SqlParameter to Udt.
• B.  Set the SqlDbType of SqlParameter to Udt.
• C.  Set the ParameterDirection of SqlParameter to Output.
• D.  Set the SqlDbType of SqlParameter to Variant.

You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create an application.
The application connects to a Microsoft SQL Server database.
You use the following SQL statement to retrieve an instance of a DataSet object named ds:
SELECT CustomerID, CompanyName, ContactName, Address, City FROM dbo.Customers
You need to query the DataSet object to retrieve only the rows where the ContactName field is not NULL. Which code segment should you use?

• A.  from row in ds.Tables[0].AsEnumerable() where !Convert.IsDBNull(row.Field<string>("ContactName")) select row;
• B.  from row in ds.Tables[0].AsEnumerable() where !row.IsNull((string)row["ContactName"]) select row;
• C.  from row in ds.Tables[0].AsEnumerable() where (string)row["ContactName"] != null select row;
• D.  from row in ds.Tables[0].AsEnumerable() where row.Field<string>("ContactName") != null select row;

The database contains a table named Categories. The Categories table has a primary key identity column
named CategoryID.
The application inserts new records by using the following stored procedure.
CREATE PROCEDURE dbo.InsertCategory @CategoryName nvarchar(15), @Identity int OUT
AS INSERT INTO Categories (CategoryName) VALUES(@CategoryName) SET @Identity = SCOPE_IDENTITY() RETURN @@ROWCOUNT
You write the following code segment.
SqlDataAdapter adapter = new SqlDataAdapter("SELECT categoryID, CategoryName
FROM dbo.Categories",connection);
adapter.InsertCommand = new SqlCommand("dbo.InsertCategory", connection);
adapter.InsertCommand.CommandType = commandType.StoredProcedure;
adapter.InsertCommand.Parameters.Add(new SqlParameter("@CategoryName",
SqlDbType.NVarChar, 15,"CategoryName"));
You need to retrieve the identity value for the newly created record. Which code segment should you add?

• A.  SqlParameter parameter = adapter.InsertCommand.Parameters.Add("@RowCount", SqlDbType.Int); parameter.Direction = ParameterDirection.Output; parameter = adapter.InsertCommand.Parameters.Add("@Identity", SqlDbType.Int, 0, "CategoryID"); parameter.Direction = ParameterDirection.ReturnValue;
• B.  SqlParameter parameter = adapter.InsertCommand.Parameters.Add("@RowCount", SqlDbType.Int); parameter.Direction = ParameterDirection.ReturnValue; parameter = adapter.InsertCommand.Parameters.Add("@Identity", SqlDbType.Int, 0, "CategoryID"); parameter.Direction = ParameterDirection.Output;
• C.  SqlParameter parameter = adapter.InsertCommand.Parameters.Add("@CategoryName", SqlDbType.Int); parameter.Direction = ParameterDirection.Output; parameter = adapter.InsertCommand.Parameters.Add("@Identity", SqlDbType.Int, 0, "CategoryID"); parameter.Direction = ParameterDirection.ReturnValue;
• D.  SqlParameter parameter = adapter.InsertCommand.Parameters.Add("@CategoryName", SqlDbType.Int); parameter.Direction = ParameterDirection.Output; parameter = adapter.InsertCommand.Parameters.Add("@Identity", SqlDbType.Int, 0, "CategoryID"); parameter.Direction = ParameterDirection.Output;

You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create an application.
The application connects to a Microsoft SQL Server database.
The application uses the ADO.NET LINQ to SQL model to retrieve data from the database.
The application will not modify retrieved data. You need to ensure that all the requested data is retrieved.
You want to achieve this goal using the minimum amount of resources. What should you do?

• A.  Set ObjectTrackingEnabled to false on the DataContext class.
• B.  Set ObjectTrackingEnabled to true on the DataContext class.
• C.  Set DeferredLoadingEnabled to false on the DataContext class.
• D.  Set DeferredLoadingEnabled to true on the DataContext class.
