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


When running an operation, you updated a column named EndTime for several records in the Project table, but updates to the corresponding task records in the Task table failed.
You need to synchronize the value of the EndTime column in the Task table with the value of the EndTime
column in the project table. The solution must meet the following requirements:
* If the EndTime column has a value, make no changes to the record.
* If the value of the EndTime column is null and the corresponding project record is marked as completed, update the record with the project finish time.
Which four 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.

Answer:

Explanation: Box 1: UPDATE T SET T.EndTime = P.EndTime
We are updating the EndTime column in the Task table. Box 2: FROM Task AS T
Where are updating the task table.
Box 3:INNER JOIN Project AS P on T.ProjectID = P.ProjectID
We join with the Project table (on the ProjectID columnID column). Box 4: WHERE P.EndTime is NOT NULL AND T.EndTime is NULL
We select the columns in the Task Table where the EndTime column in the Project table has a value (NOT NULL), but where it is NULL in the Task Table.

Answer: AB

Explanation: Using Cross Joins
A cross join that does not have a WHERE clause produces the Cartesian product of the tables involved in the join. The size of a Cartesian product result set is the number of rows in the first table multiplied by the number of rows in the second table.
However, if a WHERE clause is added, the cross join behaves as an inner join. B: You can use the IIF in the ON-statement.
IIF returns one of two values, depending on whether the Boolean expression evaluates to true or false in SQL Server.

NEW QUESTION 15
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:

The marketing department is performing an analysis of how discount affect credit limits. They need to know the average credit limit per standard discount percentage for customers whose standard discount percentage is between zero and four.
You need to create a query that returns the data for the analysis.
How should you complete the Transact-SQL statement? To answer, drag the appropriate Transact-SQL segments to the correct locations. Each Transact-SQL segments 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.

Answer:

Explanation: Box 1: 0, 1, 2, 3, 4
Pivot example:
-- Pivot table with one row and five columns
SELECT 'AverageCost' AS Cost_Sorted_By_Production_Days, [0], [1], [2], [3], [4]
FROM
(SELECT DaysToManufacture, StandardCost FROM Production.Product) AS SourceTable PIVOT
(
AVG(StandardCost)
FOR DaysToManufacture IN ([0], [1], [2], [3], [4])
) AS PivotTable; Box 2: [CreditLimit]
Box 3: PIVOT
You can use the PIVOT and UNPIVOT relational operators to change a table-valued expression into another table. PIVOT rotates a table-valued expression by turning the unique values from one column in the expression into multiple columns in the output, and performs aggregations where they are required on any remaining column values that are wanted in the final output.
Box 4: 0, 1, 2, 3, 4
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 expression[ ,... n ]
is a list of expressions to test for a match. All expressions must be of the same type as test_expression. References: https://technet.microsoft.com/en-us/library/ms177410(v=sql.105).aspx

- all customer information for the customer
- the total number of orders for the customer
- the total price of all orders for the customer
- the average quantity of items per order
How should you complete the function definition? To answer, drag the appropriate Transact-SQL segment to the correct locations. 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.

Answer:

Explanation: Box1: RETURNS TABLE
The function should return the following information:
- all customer information for the customer
- the total number of orders for the customer
- the total price of all orders for the customer
- the average quantity of items per order Box 2: COUNT
The function should return the total number of orders for the customer. Box 3: SUM
The function should return the total price of all orders for the customer. Box 3. AVG
The function should return the average quantity of items per order. Box 4: GROUP BY
Need to use GROUP BY for the aggregate functions.

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.
