Question 1:

SIMULATION

You have a database that contains the following tables.

You need to create a query that lists the lowest-performing salespersons based on the current year-to-date sales period. The query must meet the following requirements:

Return a column named Fullname that includes the salesperson FirstName, a space, and then LastName.

Include the current year-to-date sales for each salesperson.

Display only data for the three salespersons with the lowest year-to-year sales values.

Exclude salespersons that have no value for TerritoryID.

Construct the query using the following guidelines:

Use the first letter of a table name as the table alias.

Use two-part column names.

Do not surround object names with square brackets.

Do not use implicit joins.

Use only single quotes for literal text.

Use aliases only if required.

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.

Use the Check Syntax button to verify your work. Any syntax or spelling errors will be reported by line and character position.

A. Check the answer in explanation.

Correct Answer: A


Question 2:

Note: This question is part of a series of questions that use the same or similar answer choices. An answer choice may be correct for more than one question in the series. Each question is independent of the other questions in this series. Information and details provided in a question apply only to that question.

Multiple processes use the data from a table named Sales and place it in other databases across the organization. Some of the processes are not completely aware of the data types in the Sales table. This leads to data type conversion errors.

You need to implement a method that returns a NULL value id data conversion fails instead of throwing 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

Correct Answer: H

TRY_CONVERT returns a value cast to the specified data type if the cast succeeds; otherwise, returns null. References: https://docs.microsoft.com/en-us/sql/t-sql/functions/try-convert-transact-sql


Question 3:

You have a database that contains the following tables:

You need to write a query that returns a list of all customers who have not placed orders. Which Transact-SQL statement should you run?

A. SELECT c.custid FROM Sales.Customers c INNER JOIN Sales.Order oON c.custid = o.custid

B. SELECT custid FROM Sales.Customers INTERSECTSELECT custid FROM Sales.Orders

C. SELECTc.custid FROM Sales.Customers c LEFT OUTER Sales.Order oON c.custid = o.custid

D. SELECT c.custid FROM Sales.Customers c LEFT OUTER JOIN Sales.Order oON c.custid = o.custid WHERE orderid IS NULL

E. SELECT custid FROM Sales.Customers UNION ALL SELECT custid FROM Sales.Orders

F. SELECT custid FROM Sales.Customers UNION SELECT custid FROM Sales.Orders

G. SELECT c.custid FROM Sales.Customers c RIGHT OUTER JOIN Sales.Orders o ON c.custid = o.custid

Correct Answer: D

Inner joins return rows only when there is at least one row from both tables that matches the join condition. Inner joins eliminate the rows that do not match with a row from the other table. Outer joins, however, return all rows from at least one of the tables or views mentioned in the FROM clause, as long as those rows meet any WHERE or HAVING search conditions. All rows are retrieved from the left table referenced with a left outer join, and all rows from the right table referenced in a right outer join. All rows from both tables are returned in a full outer join.
