You use Microsoft SQL Server 2012 to develop a database application.
You need to implement a computed column that references a lookup table by using an
INNER JOIN against another table.
What should you do?
Which Transact-SQL statement should you use?
You administer a Microsoft SQL Server 2012 database named ContosoDb. The database
contains a table named Suppliers and a column named IsActive in the Purchases schema.
You create a new user named ContosoUser in ContosoDb. ContosoUser has no
permissions to the Suppliers table. You need to ensure that ContosoUser can delete rows
that are not active from Suppliers. You also need to grant ContosoUser only the minimum
required permissions. Which Transact-SQL statement should you use?
You need to evaluate existing and potential clustered and non-clustered indexes that will improve performance
You administer a Microsoft SQL Server 2012 server. You plan to deploy new features to an
application. You need to evaluate existing and potential clustered and non-clustered indexes
that will improve performance.
What should you do?
You need to recover the corrupted data in the minimum amount of time
Which Transact-SQL query should you use?
Your database contains a table named SalesOrders. The table includes a DATETIME
column named OrderTime that stores the date and time each order is placed. There is a
non-clustered index on the OrderTime column.
The business team wants a report that displays the total number of orders placed on the
current day.
You need to write a query that will return the correct results in the most efficient manner.
Which Transact-SQL query should you use?
Which approach should you use?
Your application contains a stored procedure for each country. Each stored procedure
accepts an employee identification number through the @EmpID parameter.
You plan to build a single process for each employee that will execute the stored procedure
based on the country of residence.
Which approach should you use?
Which Transact-SQL statement should you use?
You use Microsoft SQL Server 2012 to develop a database application.
You create a stored procedure named dbo.ModifyData that can modify rows.
You need to ensure that when the transaction fails, dbo.ModifyData meets the following
requirements:
Does not return an error
Closes all opened transactions

You are developing a database application by using Microsoft SQL Server 2012.
You have a query that runs slower than expected.
You need to capture execution plans that will include detailed information on missing
indexes recommended by the query optimizer.
What should you do?
You need to reduce procedure cache usage from these statements without creating any additional indexes
You are developing a database application by using Microsoft SQL Server 2012.
An application that uses a database begins to run slowly.
You discover that a large amount of memory is consumed by single-use dynamic queries.
