  The datetime datetype defines a date that is combined with a time of day with fractional seconds that is based on a 24-hour clock. The DATEFROMPARTS function returns a date value for the specified year, month, and day.

  Incorrect Answers:

  A: ValidFrom should be less (<) than @sdate AND ValidTo should be greater (>) than @edate.

  B: We should add a day with DATEADD, not subtract one day.

  C: We cannot compare a date to an exact datetime.

  You have a table named AuditTrail that tracks modifications to data in other tables. The AuditTrail table is updated by many processes. Data input into AuditTrail may contain improperly formatted date time values. You implement a process that retrieves data from the various columns in AuditTrail, but sometimes the process throws an error when it is unable to convert the data into valid date time values. You need to convert the data into a valid date time value using the en-US format culture code. If the conversion fails, a null value must be returned in the column output. The conversion process must not throw an error.

  What should you implement?

  A. the COALESCE function
  B. a view
  C. a table-valued function
  D. the TRY_PARSE function
  E. a stored procedure
  F. the ISNULL function
  G. a scalar function
  H. the TRY_CONVERT function
  H. the TRY_CONVERT function

  ---

  A TRY_CONVERT function returns a value cast to the specified data type if the cast succeeds; otherwise, returns null. References: https://msdn.microsoft.com/en-us/library/hh230993.aspx

• Question 65:

  HOTSPOT

  You have the following stored procedure:

  

  You run the following Transact-SQL statements:

  

  What is the result of each Transact-SQL statement? To answer, select the appropriate options in the answer area.

  Hot Area:

  

  

  ---

  Box 1: All transactions are rolled back.

  The first IF-statement, IF @CODE = 'C2323' AND @ApplicationID = 1, will be true, an error will be raised, the error will be caught in the CATCH block, and the only transaction that has been started will be rolled back.

  Box 2: Only Log1, Log2, and Log3 tables are updated.

  The second IF-statement, IF @Code = 'C2323', will be true, so the second transaction will be rolled back, but log1, log2, and log3 was updated before the second transaction.

• Question 66:

  DRAG DROP

  You have a database that contains the following tables:

  

  A delivery person enters an incorrect value for the CustomerID column in the Invoices table and enters the following text in the ConfirmedReceivedBy column: "Package signed for by the owner Tim."

  You need to find the records in the Invoices table that contain the word Tim in the CustomerName field along with the incorrectly entered row from the Sales.Invoice table.

  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.

  Select and Place:

  Box 1:SELECT CustomerID FROM Sales.Invoices

  Box 2:INNER JOIN Sales.Customers.CustomerID = Sales.Invoices.CustomerID

  Box 3:WHERE CustomerName LIKE '%tim%'

  Box 4:WHERE ConfirmedReceiveBy IN (SELECT CustomerName FROM Sales.Customers)

  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 thescenario 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:

  1. Every record has a value in the ManagerID except for the Chief Executive Officer (CEO).

  2. The FirstName and MiddleName columns contain null values for some records.

  3. The valid values for the Title column are Sales Representative, Manager, and CEO.

  You review the SalesSummary table and make the following observations:

  1. 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: ####.##.

  2. You observe that for many records, the unit price portion of the ProductCode column contains values.

  3. The RegionCode column contains NULL for some records.

  4. 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:

  1. be joinable with the SELECT statement that supplies data for the report

  2. can be used multiple times with the SELECT statement for the report

  3. be usable only with the SELECT statement for the report

  4. 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:

  1. be joinable with the SELECT statement that supplies data for the report

  2. can be used multiple times for this report and other reports

  3. accept parameters

  4. 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.
