You have a database that contains the tables shown in the exhibit. (Click the Exhibit button).

You need to create a query for a report. The query must meet the following requirements:
* NOT use object delimiters.
* Return the most recent orders first.
* Use the first initial of the table as an alias.
* Return the most recent order date for each customer.
* Retrieve the last name of the person who placed the order.
* Return the order date in a column named MostRecentOrderDate that appears as the last column in the report.
The solution must support the ANSI SQL-99 standard.
Which code segment should you use?
To answer, type the correct code in the answer area.

• A. SELECT C.LastName, MAX(O.OrderDate) AS MostRecentOrderDate
  FROM Customers AS C INNER JOIN Orders AS O
  ON C.CustomerID = O.CustomerID
  GROUP BY C.LastName
  ORDER BY MostRecentOrderDate DESC
• B. SELECT C.LastName, MAX(O.OrderDate) AS MostRecentOrderDate
  FROM Customers AS C INNER JOIN Orders AS O
  ON C.CustomerID
  GROUP BY C.LastName
  ORDER BY MostRecentOrderDate DESC

You administer a Microsoft SQL Server 2012 database. The database contains a table named Employee. Part of the Employee table is shown in the exhibit. (Click the Exhibit button.)


Unless stated above, no columns in the Employee table reference other tables.
Confidential information about the employees is stored in a separate table named EmployeeData. One record exists within EmployeeData for each record in the Employee table.
You need to assign the appropriate constraints and table properties to ensure data integrity and visibility.
On which column in the Employee table should you use an identity specification to include a seed of 1,000 and an increment of 1?

• A. EmployeeNum
• B. LastName
• C. JobTitle
• D. FirstName
• E. EmployeeID
• F. DateHired
• G. ReportsToID
• H. MiddleName
• I. DepartmentID

You are a database developer of a Microsoft SQL Server database.
You are designing a table that will store Customer data from different sources. The table will include a column that contains the CustomerID from the source system and a column that contains the SourceID.
A sample of this data is as shown in the following table.

You need to ensure that the table has no duplicate CustomerID within a SourceID. You also need to ensure that the data in the table is in the order of SourceID and then CustomerID.
Which Transact- SQL statement should you use?

• A. CREATE TABLE Customer(SourceID int NOT NULL,CustomerID int NOT NULL,CustomerName varchar(255) NOT NULLCONSTRAINT UQ_Customer UNIQUE(SourceID, CustomerID));
• B. CREATE TABLE Customer(SourceID int NOT NULL PRIMARY KEY CLUSTERED,CustomerID int NOT NULL UNIQUE,CustomerName varchar(255) NOT NULL);
• C. CREATE TABLE Customer(SourceID int NOT NULL,CustomerID int NOT NULL,CustomerName varchar(255) NOT NULL,CONSTRAINT PK_Customer PRIMARY KEY CLUSTERED(SourceID, CustomerID));
• D. CREATE TABLE Customer(SourceID int NOT NULL UNIQUE,CustomerID int NOT NULL UNIQUE,CustomerName varchar(255) NOT NULL);

You administer a Microsoft SQL Server 2012 database named ContosoDb. Tables are defined as shown in the exhibit. (Click the Exhibit button.)

You need to display rows from the Orders table for the Customers row having the CustomerId value set to 1 in the following XML format:
<row OrderId="1" OrderDate="2000-01-01T00:00:00" Amount="3400.00" Name="Customer A" Country="Australia" />
<row OrderId="2" OrderDate="2001-01-01T00:00:00" Amount="4300.00" Name="Customer A" Country="Australia" /> Which Transact-SQL query should you use?

• A. SELECT Name, Country, OrderId, OrderDate, Amount
  FROM Orders INNER JOIN Customers ON Orders.CustomerId= Customers.CustomerId WHERE Customers.CustomerId = 1 FOR XML AUTO, ELEMENTS
• B. SELECT OrderId, OrderDate, Amount, Name, Country
  FROM Orders INNER JOIN Customers ON Orders.CustomerId = Customers.CustomerId WHERE Customers.CustomerId = 1 FOR XML AUTO
• C. SELECT OrderId, OrderDate, Amount, Name, Country
  FROM Orders INNER JOIN Customers ON Orders.CustomerId = Customers.CustomerId WHERE Customers.CustomerId = 1 FOR XML RAW
• D. SELECT OrderId, OrderDate, Amount, Name, Country
  FROM Orders INNER JOIN Customers ON Orders.CustomerId - Customers.CustomerId WHERE Customers.CustomerId = 1 FOR XML AUTO, ELEMENTS
• E. SELECT Name, Country, OrderId, OrderDate, Amount
  FROM Orders INNER JOIN Customers ON Orders.CustomerId= Customers.CustomerId WHERE Customers.CustomerId = 1 FOR XML AUTO
• F. SELECT Name AS '@Name', Country AS '@Country', OrderId, OrderDate, Amount FROM Orders INNER JOIN Customers ON Orders.CustomerId= Customers.CustomerId WHERE Customers.CustomerId = 1 FOR XML PATH ('Customers')
• G. SELECT OrderId, OrderDate, Amount, Name, Country
  FROM Orders INNER JOIN Customers ON Orders.CustomerId = Customers.CustomerId WHERE Customers.CustomerId = 1 FOR XML RAW, ELEMENTS
• H. SELECT Name AS 'Customers/Name', Country AS 'Customers/Country', OrderId, OrderDate, Amount FROM Orders INNER JOIN Customers ON Orders.CustomerId= Customers.CustomerId WHERE Customers.CustomerId = 1 FOR XML PATH ('Customers')

You are maintaining a SQL Server database that uses the default settings. The database contains a table that is defined by the following Transact-SQL statement:

You must write a query that returns the AddressLine1, AddressLine2, and Region fields separated by carriage returns. You must return an empty string for any null values.

• A. Option B
• B. Option D
• C. Option C
• D. Option A
