You are a database administrator for an online retail store. You create a table to track orders by running the following Transact-SQL statement:

You are developing a query that will be used as a JSON data source for a web application. The web application requires JSON in the following format:

Correct Answer:

Explanation


Box 1: Order.Date
In PATH mode, you can use the dot syntax - for example, 'Item.UnitPrice' - to format nested output.
Here's a sample query that uses PATH mode with the FOR JSON clause. The following example also uses the ROOT option to specify a named root element.

Box 2: JSON_VALUE(LineTotal)
JSON_VALUE extracts a scalar value from a JSON string.
Box 3: Order.Product
Box 4: FOR JSON PATH
When you use the FOR JSON clause, you can specify the structure of the JSON output explicitly, or let the structure of the SELECT statement determine the output.
To maintain full control over the format of the JSON output, use FOR JSON PATH. You can create wrapper objects and nest complex properties.
To format the JSON output automatically based on the structure of the SELECT statement, use FOR JSON AUTO.
Box 5: FOR JSON PATH, ROOT('ORDER)
Use the ROOT option to specify a named root element.

Each question is independent of the other questions in this series. Information and details provided in a question apply only to that question.
You have a database that is denormalized. Users make frequent changes to data in a primary table.
You need to ensure that users cannot change the tables directly, and that changes made to the primary table also update any related tables.
What should you implement?

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

You have a database that contains the following tables.

You need to create a query that lists all complaints from the Complaints table, and the name of the person handling the complaints if a person is assigned. The ComplaintID must be displayed first, followed by the person name.
Construct the query using the following guidelines:
- Use two-part column names.
- Use one-part table names.
- Do not use aliases for column names or table names.
- Do not use Transact-SQL functions.
- Do not use implicit joins.
- 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.

You have a database that stores sales and order information.
Users must be able to extract information from the tables on an ad hoc basis. They must also be able to reference the extracted information as a single table.
You need to implement a solution that allows users to retrieve the data required, based on variables defined at the time of the query.
What should you implement?

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

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.
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.

Correct Answer:

Explanation

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)
