NEW QUESTION 7
You have the following subqueries: Subquery1, Subquery2, and Subquery3.
You need to replace the three subqueries with named result sets or temporary tables. The following requirements must be met:

Which replacement techniques should you use? To answer, select the appropriate options in the answer area.

Answer:

Explanation: Subquery1: common table expression (CTE)
A common table expression (CTE) can be thought of as a temporary result set that is defined within the execution scope of a single SELECT, INSERT, UPDATE, DELETE, or CREATE VIEW statement. A CTE is similar to a derived table in that it is not stored as an object and lasts only for the duration of the query. Unlike a derived table, a CTE can be self-referencing and can be referenced multiple times in the same query.
Subquery2: global temporary table
Global temporary tables are visible to any user and any connection after they are created, and are deleted when all users that are referencing the table disconnect from the instance of SQL Server.
Subquery3: local temporary table
Local temporary tables are visible only to their creators during the same connection to an instance of SQL Server as when the tables were first created or referenced. Local temporary tables are deleted after the user disconnects from the instance of SQL Server.

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

You need to develop a query that meets the following requirements:
* Output data by using a tree-like structure.
* Allow mixed content types.
* Use custom metadata attributes.
Which Transact-SQL statement should you run?

• A. Option A
• B. Option B
• C. Option C
• D. Option D
• E. Option E
• F. Option F
• G. Option G
• H. Option H

Answer: F

Explanation: In a FOR XML clause, you specify one of these modes: RAW, AUTO, EXPLICIT, and PATH.
* The EXPLICIT mode allows more control over the shape of the XML. You can mix attributes and elements at will in deciding the shape of the XML. It requires a specific format for the resulting rowset that is generated because of query execution. This rowset format is then mapped into XML shape. The power of EXPLICIT mode is to mix attributes and elements at will, create wrappers and nested complex properties, create
space-separated values (for example, OrderID attribute may have a list of order ID values), and mixed contents.
* The PATH mode together with the nested FOR XML query capability provides the flexibility of the EXPLICIT mode in a simpler manner.

NEW QUESTION 9
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 creating a report to show when the first customer account was opened in each city. The report contains a line chart with the following characteristics:
- The chart contains a data point for each city, with lines connecting the points.
- The X axis contains the position that the city occupies relative to other cities.
- The Y axis contains the date that the first account in any city was opened. An example chart is shown below for five cities:

During a sales promotion, customers from various cities open new accounts on the same date. You need to write a query that returns the data for the chart.
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.
NOTE: Each correct selection is worth one point.

Answer:

Explanation: Box 1: RANK() OVER
RANK returns the rank of each row within the partition of a result set. The rank of a row is one plus the number of ranks that come before the row in question.
ROW_NUMBER and RANK are similar. ROW_NUMBER numbers all rows sequentially (for example 1, 2, 3, 4, 5).

- 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: B

Explanation: With X_ABORT ON the INSERT INTO statement and the transaction will be rolled back when an error is raised, it would then not be possible to ROLLBACK it again in the IF XACT_STATE() <> 0 ROLLACK TRANSACTION statement.
Note: 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, finally an error 51000 will be raised.
Note: When SET XACT_ABORT is ON, if a Transact-SQL statement raises a run-time error, the entire transaction is terminated and rolled back.
XACT_STATE is a scalar function that reports the user transaction state of a current running request. XACT_STATE indicates whether the request has an active user transaction, and whether the transaction is capable of being committed.
The states of XACT_STATE are:
0 There is no active user transaction for the current request.
1 The current request has an active user transaction. The request can perform any actions, including writing data and committing the transaction.
2 The current request has an active user transaction, but an error has occurred that has caused the transaction to be classified as an committable transaction.
