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 on this series.

You have a database that tracks orders and deliveries for customers in North America. System versioning is enabled for all tables. The database contains the Sales.Customers, Application.Cities, and Sales.CustomerCategories tables.

Details for the Sales.Customers table are shown in the following table:

Details for the Application.Cities table are shown in the following table:

Details for the Sales.CustomerCategories table are shown in the following table:

You are preparing a promotional mailing. The mailing must only be sent to customers in good standing that live in medium and large cities.

You need to write a query that returns all customers that are not on credit hold who live in cities with a population greater than 10,000.

How should you complete the Transact-SQL statement? To answer, drag the appropriate Transact-SQL segments to the correct locations. Each Transact-SQL segment may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.

Explanation:

Box 1: IN (

The IN clause determines whether a specified value matches any value in a subquery or a list.

Syntax: test_expression [ NOT ] IN ( subquery | expression [ ,...n ] ) Where subquery

Is a subquery that has a result set of one column. This column must have the same data type as test_expression.

Box 2: WHERE

Q2. Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.

After you answer a question in this section. you will NOT be able to return to it. As a result, these questions will not appear in the review screen.

You create a table named Products by running the following Transact-SQL statement:

You have the following stored procedure:

You need to modify the stored procedure to meet the following new requirements:

- Insert product records as a single unit of work.

- Return error number 51000 when a product fails to insert into the database.

- If a product record insert operation fails, the product information must not be permanently written to the database.

Solution: You run the following Transact-SQL statement:

Does the solution meet the goal?

A. Yes

B. No

Answer: A

Explanation:

If the INSERT INTO statement raises an error, the statement will be caught and an error 51000 will be thrown. In this case no records will have been inserted.

Note:

You can implement error handling for the INSERT statement by specifying the statement in a TRY…CATCH construct.

If an INSERT statement violates a constraint or rule, or if it has a value incompatible with

the data type of the column, the statement fails and an error message is returned. References: https://msdn.microsoft.com/en-us/library/ms174335.aspx

The FOR SYSTEM_TIME ALL clause returns all the row versions from both the Temporal and History table.

Note: A system-versioned temporal table defined through is a new type of user table in SQL Server 2021, here defined on the last line WITH (SYSTEM_VERSIONING = ON…, is designed to keep a full history of data changes and allow easy point in time analysis.

To query temporal data, the SELECT statement FROM<table> clause has a new clause FOR SYSTEM_TIME with five temporal-specific sub-clauses to query data across the current and history tables.

Q7. HOTSPOT

You query a database that includes two tables: Project and Task. The Project table includes the following columns:

You need to identify the owner of each task by using the following rules:

- Return each task’s owner if the task has an owner.

- If a task has no owner, but is associated with a project that has an owner, return the project’s owner.

- Return the value -1 for all other cases.

How should you complete the Transact-SQL statement? To answer, select the appropriate Transact-SQL segments in the answer area.

Answer:

Explanation:

Box 1: COALESCE

COALESCE evaluates the arguments in order and returns the current value of the first

expression that initially does not evaluate to NULL.

Box 2: T.UserID, p.UserID, -1

- Return each task’s owner if the task has an owner.

- If a task has no owner, but is associated with a project that has an owner, return the project’s owner.

- Return the value -1 for all other cases.

Box 3: RIGHT JOIN

The RIGHT JOIN keyword returns all rows from the right table (table2), with the matching rows in the left table (table1). The result is NULL in the left side when there is no match. Here the right side could be NULL as the projectID of the task could be NULL.

Q8. You have a database that contains the following tables:

Customer

CustomerAudit

Where the value of the CustomerID column equals 3, you need to update the value of the CreditLimit column to 1000 for the customer. You must ensure that the change to the record in the Customer table is recorded on the CustomerAudit table.

Which Transact-SQL statement should you run?

A. Option A

B. Option B

C. Option C

D. Option D

Answer: D

Explanation:

The OUTPUT Clause returns information from, or expressions based on, each row affected by an INSERT, UPDATE, DELETE, or MERGE statement. These results can be returned to the processing application for use in such things as confirmation messages, archiving, and other such application requirements. The results can also be inserted into a table or table variable. Additionally, you can capture the results of an OUTPUT clause in a nested INSERT, UPDATE, DELETE, or MERGE statement, and insert those results into a target table or view.

Note: If the column modified by the .RITE clause is referenced in an OUTPUT clause, the complete value of the column, either the before image in deleted.column_name or the after image in inserted.column_name, is returned to the specified column in the table variable.

Q9. Note: This question is part of a series of questions that use the same or similar answer choices. An answer choice may be correct for more than one question in the series. Each question is independent of the other questions in this series. Information and details provided in a question apply only to that question.

You have a database that contains tables named Customer_CRMSystem and Customer_HRSystem. Both tables use the following structure:

The tables include the following records: Customer_CRMSystem

Customer_HRSystem

Q10. HOTSPOT

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 database object that calculates the total price of an order including the sales tax. The database object must meet the following requirements:

- Reduce the compilation cost of Transact-SQL code by caching the plans and reusing them for repeated execution.

- Return a value.

- Be callable from a SELECT statement.

How should you complete the Transact-SQL statements? To answer, select the appropriate Transact-SQL segments in the answer area.

Answer:

Explanation:

Box 1: FUNCTION

To be able to return a value we should use a scalar function.

CREATE FUNCTION creates a user-defined function in SQL Server and Azure SQL Database. The return value can either be a scalar (single) value or a table.

Box 2: RETURNS decimal(18,2)

Use the same data format as used in the UnitPrice column.

Box 3: BEGIN

Transact-SQL Scalar Function Syntax include the BEGIN ..END construct.

CREATE [ OR ALTER ] FUNCTION [ schema_name. ] function_name

( [ { @parameter_name [ AS ][ type_schema_name. ] parameter_data_type [ = default ] [ READONLY ] }

[ ,...n ]

]

)

RETURNS return_data_type

[ WITH <function_option> [ ,...n ] ] [ AS ]

BEGIN

function_body

RETURN scalar_expression END

[ ; ]

Box 4: @OrderPrice * @CalculatedTaxRate Calculate the price including tax.

Box 5: END

Transact-SQL Scalar Function Syntax include the BEGIN ..END construct. References: https://msdn.microsoft.com/en-us/library/ms186755.aspx
