FROM Sale INNER JOIN SalesPerson
ON Sale.SalesPersonID = SalesPerson.SalesPersonID
GROUP BY GROUPING SETS((SalesPerson.Name, Country, City, DatePart(yyyy,
SaleDate)), (Country, City), (Country), ())
B. SELECT SalesPerson.Name, Country, City,
DatePart(yyyy, SaleDate) AS Year, Sum(Amount) AS Total

DatePart(yyyy, SaleDate) AS Year, Sum(Amount) AS Total
FROM Sale INNER JOIN SalesPerson
ON Sale.SalesPersonID = SalesPerson.SalesPersonID

Q32. You are developing a database application by using Microsoft SQL Server 2012.
An application that uses a database begins to run slowly.
Your investigation shows the root cause is a query against a read-only table that has a
clustered index.

B. Add a LOOP hint to the query.
C. Add a FORCESEEK hint to the query.
D. Add an INCLUDE clause to the index.
E. Add a FORCESCAN hint to the Attach query.
F. Add a columnstore index to cover the query.
G. Enable the optimize for ad hoc workloads option.
H. Cover the unique clustered index with a columnstore index.
I. Include a SET FORCEPLAN ON statement before you run the query.
J. Include a SET STATISTICS PROFILE ON statement before you run the query.
K. Include a SET STATISTICS SHOWPLAN_XML ON statement before you run the query.
L. Include a SET TRANSACTION ISOLATION LEVEL REPEATABLE READ statement before you run the query.
M. Include a SET TRANSACTION ISOLATION LEVEL SNAPSHOT statement before you run the query.
N. Include a SET TRANSACTION ISOLATION LEVEL SERIALIZABLE statement before you run the query.

Q33. 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));
GO
