A. Option A B. Option B C. Option C D. Option D Answer: A Explanation: 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. References: https://docs.microsoft.com/en-us/sql/t-sql/queries/from-using-pivot-and- unpivotviewsql-server-2017 Question: 2 DRAG DROP You develop a Microsoft SQL Server database for a sales ordering application. You want to create a report that displays the increase of order quantities over the previous year for each product. You need to write a query that displays: Product name Year of sales order Sales order quantity and Increase of order quantity over the previous year. https://www.realexamdumps.com/microsoft/70-461-practice-test.html

slide 6:

Which three 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: https://www.realexamdumps.com/microsoft/70-461-practice-test.html

Box 1: FROM .. Box 2: LAG not LEAD Lag accesses data from a previous row in the same result set without the use of a self-join starting with SQL Server 2012 11.x. LAG provides access to a row at a given physical offset that comes before the current row. Use this analytic function in a SELECT statement to compare values in the current row with values in a previous row. Not lead: Lead accesses data from a subsequent row in the same result set without the use of a self-join starting with SQL Server 2012 11.x. LEAD provides access to a row at a given physical offset that follows the current row. Box 3: GROY BY PRO.NAME YEAR OrderDate References: https://docs.microsoft.com/en-us/sql/t-sql/functions/lag-transact-sqlviewsql-server-2017 Question: 3 You develop a Microsoft SQL Server database that contains a table named Employee defined as follows: https://www.realexamdumps.com/microsoft/70-461-practice-test.html

Box 1: UNION ALL UNION combines the results of two or more queries into a single result set that includes all the rows that belong to all queries in the union. UNION ALL Incorporates all rows into the results. This includes duplicates. If ALL is not specified duplicate rows are removed. Box 2: INTERSECT INTERSECT returns distinct rows that are output by both the left and right input queries operator. Box 3: INNER JOIN The INNER JOIN keyword selects records that have matching values in both tables. Box 4: MERGE Merge performs insert update or delete operations on a target table based on the results of a join with a source table. For example you can synchronize two tables by inserting updating or deleting rows in one table based on differences found in the other table. Box 5: FULL OUTER JOIN The FULL OUTER JOIN keyword return all records when there is a match in either left table1 or right table2 table records. Note: FULL OUTER JOIN can potentially return very large result-sets https://www.realexamdumps.com/microsoft/70-461-practice-test.html

slide 20:

You need to add Transact-SQL statements at line 08 to ensure that GetVendorInStateNeighbors returns the names of vendors that are located in all states where the vendor specified in the vendorname parameter has a location. Which three 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: https://www.realexamdumps.com/microsoft/70-461-practice-test.html

slide 21:

The IN statement determines whether a specified value matches any value in a subquery or a list. Incorrect: The EXISTS command specifies a subquery to test for the existence of rows. References: https://docs.microsoft.com/en-us/sql/t-sql/language-elements/in-transact-sqlviewsql- server-2017 Question: 10 A local bank uses a SQL Server database to manage accounts. You are developing a stored procedure that contains multiple Transact-SQL INSERT statements. The stored procedure must use transaction management to handle errors. You need to ensure that the stored procedure rolls back the entire transaction if a run-time occurs. Which Transact-SQL statement should you add to the stored procedure A. SET ARITHABORT ON B. SET NOEXEC ON C. SET TRANSACTION ISOLATION LEVEL ON D. SET XACT_ABORT ON Answer: D Explanation: SET XACT_ABORT specifies whether SQL Server automatically rolls back the current transaction when a Transact-SQL statement raises a run-time error. https://www.realexamdumps.com/microsoft/70-461-practice-test.html

slide 22:

When SET XACT_ABORT is ON if a Transact-SQL statement raises a run-time error the entire transaction is terminated and rolled back.
