On a lighter note, CTE's can be imagined as equivalent to temporary result sets that can be used only in an underlying SELECT,INSERT, UPDATE, DELETE or CREATE VIEW statement.;WITH CTE AS(SELECT Name , City , [State] , ROW_NUMBER() OVER(PARTITION BY Name, City, [State] ORDER BY [Name]) AS RnumFROM Persons)DELETE FROM CTE WHERE Rnum <> 1

In the code by saying WHERE Rnum <> 1, we are asking SQL Server to keep all the records with Rank 1, which are not duplicates, and delete any other record.After executing this query in SQL Server Management Studio, you will end up with no duplicates in your table. To confirm that just run a simple query against yourtable.

QUESTION 141You are developing a database in SQL Server 2012 to store information about current employee project assignments. You are creating a view that uses data fromthe project assignment table. You need to ensure that the view does not become invalid if the schema of the project assignment table changes. What should youdo?

A. Create the view by using an account in the sysadmin role.

B. Add a DDL trigger to the project assignment table to re-create the view after any schema change.

C. Create the view in a new schema.

D. Add a DDL trigger to the view to block any changes.




DDL triggers are a special kind of trigger that fire in response to Data Definition Language (DDL) statements. They can be used to perform administrative tasks inthe database such as auditing and regulating database operations.Reference: DDL Triggershttps://technet.microsoft.com/en-us/library/ms190989(v=sql.105).aspx

QUESTION 142You are maintaining a Microsoft SQL Server database that stores order information for an online store website. The database contains a table that is defined by thefollowing Transact-SQL statement.

You need to ensure that purchase order numbers are used only for a single order. What should you do?


A. Create a new CLUSTERED constraint on the PurchaseOrderNumber column.

B. Create a new UNIQUE constraint on the PurchaseOrderNumber column.

C. Create a new PRIMARY constraint on the PurchaseOrderNumber column.

D. Create a new FOREIGN KEY constraint on the PurchaseOrderNumber column.


Explanation/Reference:Explanation:You can use UNIQUE constraints to make sure that no duplicate values are entered in specific columns that do not participate in a primary key. Although both aUNIQUE constraint and a PRIMARY KEY constraint enforce uniqueness, use a UNIQUE constraint instead of a PRIMARY KEY constraint when you want to enforcethe uniqueness of a column, or combination of columns, that is not the primary key.Reference: UNIQUE Constraintshttps://technet.microsoft.com/en-us/library/ms191166(v=sql.105).aspx

A. @@ERROR

B. ERROR_NUMBER()

C. ERROR_MESSAGE()

D. XACT_STATE()

Correct Answer: ABCDSection: (none)Explanation

Explanation/Reference:XACT_STATE() : indicates whether the request has an active user transaction, and whether the transaction is capable of being committed.

1 The current request has an active user transaction. The request can perform any actions, including writing data and committing the transaction.0 There is no active user transaction for the current request.-1 The current request has an active user transaction, but an error has occurred that has caused the transaction to be classified as an uncommittable transaction.The request cannot commit the transaction or roll back to a savepoint; it can only request a full rollback of the transaction. The request cannot perform any writeoperations until it rolls back the transaction. The request can only perform read operations until it rolls back the transaction. After the transaction has been rolledback, the request can perform both read and write operations and can begin a new transaction.

C. If a T-SQL error with a severity level > 16 occurs, some statements of the transaction may still be executed.

D. If a T-SQL error with a severity level > 10 occurs, some statements of the transaction may still be executed.



severity level :Severity level 0-10: These are just information message not actual error.

Severity level 11 to 16: These are errors caused due to user mistakes. We have tried to divide value by 0 in previous article and hence we got severity error 16.

Severity Level 17: This severity indicates that an operation making SQL Server out of resources or exceeding defined limit. That may be disk space or lock limit.

Severity Level 18: This error represents nonfatal internal software error.

Severity Level 19: This error represents some non-configurable internal limit has been exceeded and the current batch process is terminated. To be very frank, Ihave not seen this severity practically in my life.

Severity Level 20: This severity indicates current statement has encountered a problem and because of this severity level client connection with SQL Server will bedisconnected.

Severity Level 21: This severity indicates that you have encountered a problem that affects all processes in the current database.

Severity Level 22: This error indicates problem with database table or index. It may be corrupt or damaged.

Severity Level 23: This error indicates problem with database integrity which may be fixed by DBCC command.

Severity Level 24: This error indicates problem with the hardware of SQL Server. Need to check disk drive and related hardware extensively.
