Microsoft Querying Data with Transact-SQL - 70-761무료 덤프문제 풀어보기
You work for an organization that monitors seismic activity around volcanos. You have a table named GroundSensors. The table stored data collected from seismic sensors. It includes the columns describes in the following table:
The database also contains a scalar value function named NearestMountain that returns the name of the mountain that is nearest to the sensor.
You need to create a query that shows the average of the normalized readings from the sensors for each mountain. The query must meet the following requirements:
- Include the average normalized readings and nearest mountain name.
- Exclude sensors for which no normalized reading exists.
- Exclude those sensors with value of zero for tremor.
Construct the query using the following guidelines:
- Use one part names to reference tables, columns and functions.
- Do not use parentheses unless required.
- Do not use aliases for column names and table names.
- Do not surround object names with square brackets.
Part of the correct Transact-SQL has been provided in the answer area below. Enter the code in the answer area that resolves the problem and meets the stated goals or requirements. You can add code within the code that has been provided as well as below it.
1. SELECT
2. FROM Sales.Products AS P

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.
Start of repeated scenario
You have a database that contains the tables shown in the exhibit. (Click the Exhibit button.)
You review the Employee table and make the following observations:
* Every record has a value in the ManagerID except for the Chief Executive Officer (CEO).
* The FirstName and MiddleName columns contain null values for some records.
* The valid values for the Title column are Sales Representative, Manager, and CEO.
You review the SalesSummary table and make the following observations:
* The ProductCode column contains two parts: The first five digits represent a product code, and the last seven digits represent the unit price. The unit price uses the following pattern: ####.##.
* You observe that for many records, the unit price portion of the ProductCode column contains values.
* The RegionCode column contains NULL for some records.
* Sales data is only recorded for sales representatives.
You are developing a series of reports and procedures to support the business. Details for each report or procedure follow.
Sales Summary report: This report aggregates data by year and quarter. The report must resemble the following table.
Sales Manager report: This report lists each sales manager and the total sales amount for all employees that report to the sales manager.
Sales by Region report: This report lists the total sales amount by employee and by region. The report must include the following columns: EmployeeCode, MiddleName, LastName, RegionCode, and SalesAmount.
If MiddleName is NULL, FirstName must be displayed.
If both FirstName and MiddleName have null values, the world Unknown must be displayed. If RegionCode is NULL, the word Unknown must be displayed.
Report1: This report joins data from SalesSummary with the Employee table and other tables. You plan to create an object to support Report1. The object has the following requirements:
* be joinable with the SELECT statement that supplies data for the report
* can be used multiple times with the SELECT statement for the report
* be usable only with the SELECT statement for the report
* not be saved as a permanent object
Report2: This report joins data from SalesSummary with the Employee table and other tables. You plan to create an object to support Report1. The object has the following requirements:
* be joinable with the SELECT statement that supplies data for the report
* can be used multiple times for this report and other reports
* accept parameters
* be saved as a permanent object
Sales Hierarchy report. This report aggregates rows, creates subtotal rows, and super-aggregates rows over the SalesAmount column in a single result-set. The report uses SaleYear, SaleQuarter, and SaleMonth columns as a hierarchy. The result set must not contain a grand total or cross-tabulation aggregate rows.
Current Price Stored Procedure: This stored procedure must return the unit price for a product when a product code is supplied. The unit price must include a dollar sign at the beginning. In addition, the unit price must contain a comma every three digits to the left of the decimal point, and must display two digits to the left of the decimal point. The stored procedure must not throw errors, even if the product code contains invalid data.
End of Repeated Scenario
You need to create the query to supply data for the Sales Hierarchy report.
Which Transact-SQL keyword should you use for each operation? To answer, drag the appropriate Transact-SQL keywords to the correct operations. Each action may be used once, more than once or not at all.
You may drag the split bar between panes or scroll to view content.

* Allow case sensitive searches for product.
* Filter search results based on exact text in the description.
* Support multibyte Unicode characters.
You run the following Transact-SQL statement:
You need to display a comma separated list of all product bugs filed by a user named User1.
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.

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.
