You have a database that contains a table named Employees. The table stored information about the employees of your company.
You need to implement the following auditing rules for the Employees table:
- Record any changes that are made to the data in the Employees table.
- Customize the data recorded by the audit operations.
Solution: You implement a stored procedure on the Employees table.
Does the solution meet the goal?

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.
You have a database named Sales that contains the following database tables: Customer, Order, and Products.
The Products table and the Order table are shown in the following diagram.

The customer table includes a column that stores the data for the last order that the customer placed.
You plan to create a table named Leads. The Leads table is expected to contain approximately 20,000 records.
Storage requirements for the Leads table must be minimized.
You need to implement a stored procedure that deletes a discontinued product from the Products table. You identify the following requirements:
* If an open order includes a discontinued product, the records for the product must not be deleted.
* The stored procedure must return a custom error message if a product record cannot be deleted. The message must identify the OrderID for the open order.
What should you do? To answer, select the appropriate Transact-SQL segments in the answer area.

You are developing an app that allows users to query historical company financial data. You are reviewing email messages from the various stakeholders for a project.
The message from the security officer is shown in the Security Officer Email exhibit below.
TO: Database developer
From: Security Officer
Subject: SQL object requirements
We need to simplify the security settings for the SQL objects. Having a assign permissions at every object in SQL is tedious and leads to a problem. Documentation is also more difficult when we have to assign permissions at multiple levels. We need to assign the required permissions at one object, even though that object may be obtaining from other objects.
The message from the sales manager is shown in the Sales Manager Email exhibit below.
TO: Database developer
From: Sales Manager
Subject: Needed SQL objects
When creating objects for our use, they need to be flexible. We will be changing the base infrastructure frequently. We need components in SQL that will provide backward compatibility to our front end applications as the environments change so that do not need to modify the front end applications. We need objects that can provide a filtered set of the data. The data may be coming from multiple tables and we need an object that can provide access to all of the data through a single object reference.
This is an example of the types of data we need to be able to have queries against without having to change the front end applications.

The message from the web developer is shown in the Web Developer Email exhibit below.
TO: Database developer
From: Web Developer
Subject: SQL Object component
Whatever you will be configuring to provide access to data in SQL, it needs to connect using the items referenced in this interface. We have been using this for a long time, and we cannot change this from end easily. Whatever objects are going to be used in SQL they must work using object types this interface references.

You need to create one or more objects that meet the needs of the security officer, the sales manager and the web developer.
For each of the following statements, select Yes if the statement is true. Otherwise, select No.

You manage a database with tables named Invoice and InvoiceDetails. Each invoice may have multiple records.
Users update the InvoiceDetails table by using a .NET web application. The application retrieves records from both tables and updates the tables by running an inline update statement.
Users experience slow performance when updating records in the application. The solution must meet the following requirements:
* Must use a stored procedure.
* Must not use inline update statements
* Must use a table-valued parameter.
* Must call the stored procedure to update all records.
You need to optimize performance.
Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.

You have a database that contains the following tables: BlogCategory, BlogEntry, ProductReview, Product, and SalesPerson. The tables were created using the following Transact SQL statements:

You must modify the ProductReview Table to meet the following requirements:
* The table must reference the ProductID column in the Product table
* Existing records in the ProductReview table must not be validated with the Product table.
* Deleting records in the Product table must not be allowed if records are referenced by the ProductReview table.
* Changes to records in the Product table must propagate to the ProductReview table.
You also have the following database tables: Order, ProductTypes, and SalesHistory, The transact-SQL statements for these tables are not available.
You must modify the Orders table to meet the following requirements:
* Create new rows in the table without granting INSERT permissions to the table.
* Notify the sales person who places an order whether or not the order was completed.
You must add the following constraints to the SalesHistory table:
* a constraint on the SaleID column that allows the field to be used as a record identifier
* a constant that uses the ProductID column to reference the Product column of the ProductTypes table
* a constraint on the CategoryID column that allows one row with a null value in the column
* a constraint that limits the SalePrice column to values greater than four Finance department users must be able to retrieve data from the SalesHistory table for sales persons where the value of the SalesYTD column is above a certain threshold.
You plan to create a memory-optimized table named SalesOrder. The table must meet the following requirements:
* The table must hold 10 million unique sales orders.
* The table must use checkpoints to minimize I/O operations and must not use transaction logging.
* Data loss is acceptable.
Performance for queries against the SalesOrder table that use Where clauses with exact equality operations must be optimized.
You need to update the SalesHistory table
How should you complete the Transact_SQL statement? To answer? select the appropriate Transact-SQL, segments in the answer area.

You are designing a solution for a company that operates retail stores. Each store has a database that tracks sales transactions. You create a summary table in the database at the corporate office. You plan to use the table to record the quantity of each product sold at each store on each day. Managers will use this data to identify reorder levels for products.
Every evening, stores must transmit s5les data to the corporate office. The data must be inserted into the summary table that includes the StorelD, ProductID, Qtysold, Totprodsales, and Datesold Columns.
You need to prevent duplicate rows in the summary table. Each row must uniquely identify the store that sold the product and the total amount sold for that store on a specific date.
What should you include in your solution?

You create a database table named FactSales by running the following Transact-SQL statements:

You must optimize the indexes without making changes to the ix_FactSales_EmployeeKey index.
You need to implement a columnstore index for the table.
How should you complete the Transact-SQL code? To answer, select the appropriate Transact-SQL segments in the answer area.
