A transaction is correctly defined for the INSERT INTO ..VALUES statement, and if there is an error in the transaction it will be caught ant he transaction will be rolled back. However, error number 51000 will not be returned, as it is only used

in an IF @ERROR = 51000 statement.

D. LEFT JOIN

E. GROUP BY CUBE

F. CROSS JOIN

G. PIVOT

H. UNPIVOT

Question 9:

HOTSPOT

You need to develop a Transact-SQL statement that meets the following requirements:

The statement must return a custom error when there are problems updating a table.

The error number must be value50555.

The error severity level must be14.

A Microsoft SQL Server alert must be triggered when the error condition occurs.

Which Transact-SQL segment should you use for each requirement? To answer, select the appropriate Transact-SQL segments in the answer area.

Hot Area:

Correct Answer:

Box 1: TRY…CATCH

The TRY…CATCH Transact-SQL construct implements error handling for Transact-SQL that is similar to the exception handling in the Microsoft Visual C# and Microsoft Visual C languages. A group of Transact-SQL statements can be

enclosed in a TRY block. If an error occurs in the TRY block, control is passed to another group of statements that is enclosed in a CATCH block.

Box 2: RAISERROR(50555, 14, 1 \’The update failed.”) WITH LOG

We must use RAISERROR to be able to specify the required severity level of 14, and we should also use the LOG option, which Logs the error in the error log and the application log for the instance of the Microsoft SQL Server Database

Engine, as this enable a MS MS SQL SERVER alert to be triggered.

Note: RAISERROR generates an error message and initiates error processing for the session. RAISERROR can either reference a user-defined message stored in the sys.messages catalog view or build a message dynamically. The

message is returned as a server error message to the calling application or to an associated CATCH block of a TRY…CATCH construct.

Incorrect Answers:

Not THROW: THROW does not have a severity parameter.

Question 10:

DRAG DROP

Note: This question is part of a series of questions that use the same scenario. For your convenience, the scenario is repeated in each question. Each question presents a different goal and answer choices, but the text of the scenario is exactly the same in each question in this series.

You are developing a database to track customer orders. The database contains the following tables: Sales.Customers, Sales.Orders, and Sales.OrderLines. The following table describes the columns in Sales.Customers.

The following table describes the columns in Sales.Orders.

The following table describes the columns in Sales.OrderLines.

You need to create a function that calculates the highest tax rate charged for an item in a specific order.

Which five Transact-SQL segments should you use to develop the solution? To answer, move the appropriate Transact-SQL segments from the list of Transact-SQL segments to the answer area and arrange them in the correct order.

Select and Place:

Correct Answer:

Box1: CREATE FUNCTION…@OrderID

Include definition for the …@OrderID parameter.

Box 2: RETURNS decimal(18,2)

The function is defined to return a scalar value.

Box 3: AS BEGIN …

Declare the local variables of the function.

Box 4: SET @CalculatedTaxRate = (..

Calculate the tax rate.

Box 5: RETURN @CalculatedRate END

Return a scalar value.
