You have the following query:

You need to recreate the query to meet the following requirements:
– Reference columns by using one-part names only.
– Sort aggregates by SalesTerritoryID, and then by ProductID.
– Order the results in descending order from SalesTerritoryID to ProductID.
– The solution must use the existing SELECT clause and FROM clause.
Which code segment should you use? To answer, type the correct code in the answer area.
Answer:
SELECT SalesTerritoryID,
ProductID,
AVG(UnitPrice),
MAX(OrderQty),
MAX(DiscountAmount)
FROM Sales.Details
GROUP BY SalesTerritoryID , ProductID
ORDER BY SalesTerritoryID DESC, ProductID DESC

QUESTION 42
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.

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.
Answer:
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 O.OrderDate DESC

QUESTION 44
You have a database that contains the tables as shown in the exhibit. (Click the Exhibit button.)

You need to create a query that returns a list of products from Sales.ProductCatalog. The solution must meet the following requirements:
– UnitPrice must be returned in descending order.
– The query must use two-part names to reference the table.
– The query must use the RANK function to calculate the results.
– The query must return the ranking of rows in a column named PriceRank.
– The list must display the columns in the order that they are defined in the table.
– PriceRank must appear last.
Which code segment should you use? To answer, type the correct code in the answer area.
Answer:
SELECT ProductCatalog.CatID, ProductCatalog.CatName, ProductCatalog.ProductID, ProductCatalog.ProdName, ProductCatalog.UnitPrice,
RANK() OVER (PARTITION BY ProductCatalog.UnitPrice ORDER BY ProductCatalog.UnitPrice DESC) AS PriceRank
FROM Sales.ProductCatalog
ORDER BY ProductCatalog.UnitPrice DESC

QUESTION 45
You have a database that contains the tables shown in the exhibit. (Click the Exhibit button.)

You have an application named Appl. You have a parameter named @Count that uses the int data type. App1 is configured to pass @Count to a stored procedure. You need to create a stored procedure named usp_Customers for Appl. Usp_Customers must meet the following requirements:
– NOT use object delimiters.
– Minimize sorting and counting.
– Return only the last name of each customer in alphabetical order.
– Return only the number of rows specified by the @Count parameter.
– The solution must NOT use BEGIN and END statements.

ORDER BY Customers.LastName

QUESTION 46
You use a Microsoft SQL Server 2012 database that contains a table named BlogEntry that has the following columns:

Id is the Primary Key. You need to append the “This is in a draft stage” string to the Summary column of the recent 10 entries based on the values in EntryDateTime. Which Transact-SQL statement should you use?

A.    UPDATE TOP(10) BlogEntry
SET Summary.WRITE(N’ This is in a draft stage’, NULL, 0)
B.    UPDATE BlogEntry
SET Summary = CAST(N’ This is in a draft stage’ as nvarchar(max))
WHERE Id IN(SELECT TOP(10) Id FROM BlogEntry ORDER BY EntryDateTime DESC)
C.    UPDATE BlogEntry
SET Summary.WRITE(N’ This is in a draft stage’, NULL, 0) FROM (
SELECT TOP(10) Id FROM BlogEntry ORDER BY EntryDateTime DESC) AS s
WHERE BlogEntry.Id = s.ID
D.    UPDATE BlogEntrySET
Summary.WRITE(N’ This is in a draft stage’, 0, 0)
WHERE Id IN(SELECT TOP(10) Id FROM BlogEntry ORDER BY EntryDateTime DESC)

Answer: C

QUESTION 47
You use Microsoft SQL Server 2012 to develop a database application. You create a stored procedure named DeleteJobCandidate. You need to ensure that if DeleteJobCandidate encounters an error, the execution of the stored procedure reports the error number. Which Transact-SQL statement should you use?

A.    DECLARE @ErrorVar INT;
DECLARE @RowCountVar INT;
EXEC DeleteJobCandidate
SELECT @ErrorVar = @@ERROR, @RowCountVar = @@ROWCOUNT;
IF (@ErrorVar <> 0)
  PRINT N’Error = ‘ + CAST(@@ErrorVar AS NVARCHAR(8)) +
    N’, Rows Deleted = ‘ + CAST(@@RowCountVar AS NVARCHAR(8));
GO
B.    DECLARE @ErrorVar INT;
DECLARE @RowCountVar INT;
EXEC DeleteJobCandidate
SELECT @ErrorVar = ERROR_STATE(), @RowCountVar = @@ROWCOUNT;
IF (@ErrorVar <> 0)
  PRINT N’Error = ‘ + CAST(ERRORSTATE() AS NVARCHAR(8)) +
    N’, Rows Deleted = ‘ + CAST(@@RowCountVar AS NVARCHAR(8));
GO
C.    EXEC DeleteJobCandidate
IF (ERROR_STATE() != 0)
  PRINT N’Error = ‘ + CAST(@@ERROR AS NVARCHAR(8)) +
    N’, Rows Deleted = ‘ + CAST(@@ROWCOUNT AS NVARCHAR(8));
GO
D.    EXEC DeleteJobCandidate
PRINT N’Error = ‘ + CAST(@@ERROR AS NVARCHAR(8)) +
  N’, Rows Deleted = ‘ + CAST(@@ROWCOUNT AS NVARCHAR(8));
