Q76. You develop a Microsoft SQL Server 2012 database that contains a table named Products. The Products table has the following definition: 


You need to create an audit record only when either the RetailPrice or WholeSalePrice column is updated. 

Which Transact-SQL query should you use? 

A. CREATE TRIGGER TrgPriceChange ON Products FOR UPDATE AS IF CCLUMNS_CHANGED(RetailPrice, WholesalePrice) - - Create Audit Records 

B. CREATE TRIGGER TrgPriceChange ON Products FOR UPDATE AS IF EXISTS(SELECT RetailPrice from inserted) OR EXISTS (SELECT WholeSalePnce FROM inserted) - - Create Audit Records 

C. CREATE TRIGGER TrgPriceChange ON Products FOR UPDATE AS IF COLUMNS_UPDATED(RetailPrice, WholesalePrice) - - Create Audit Records 

D. CREATE TRIGGER TrgPriceChange ON Products FOR UPDATE AS IF UPDATE(RetailPrice) OR UPDATE(WholeSalePrice) - - Create Audit Records 

Answer: D 


Q77. CORRECT TEXT 

You have a database that contains the tables as shown below: 


You have a stored procedure named Procedure1. Procedure1 retrieves all order ids after a specific date. The rows for Procedure1 are not sorted. Procedure1 has a single parameter named Parameter1. Parameter1 uses the varchar type and is configured to pass the specific date to Procedure1. A database administrator discovers that OrderDate is not being compared correctly to Parameter1 after the data type of the column is changed to datetime. You need to update the SELECT statement to meet the following requirements: 

The code must NOT use aliases. 

The code must NOT use object delimiters. 

The objects called in Procedure1 must be able to be resolved by all users. 

OrderDate must be compared to Parameter1 after the data type of Parameter1 is 

changed to datetime. 

Which SELECT statement should you use? 

To answer, type the correct code in the answer area. 

Answer: 


Q78. DRAG DROP 

You want to add a new GUID column named BookGUID to a table named dbo.Book that already contains data. 

BookGUID will have a constraint to ensure that it always has a value when new rows are inserted into dbo.Book. 

You need to ensure that the new column is assigned a GUID for existing rows. 

Which four Transact-SQL statements should you use? (To answer, move the appropriate SQL statements from the list of statements to the answer area and arrange them in the correct order.) 


Answer: 



Q79. 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. 

You need to reduce procedure cache usage from these statements without creating any additional indexes. 

What should you do? 

A. Add a HASH hint to the query. 

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.
