The Account table was created using the following Transact-SQL statement:

There are more than 1 billion records in the Account table. The Account Number column uniquely identifies
each account. The ProductCode column has 100 different values. The values are evenly distributed in the
table. Table statistics are refreshed and up to date.
You frequently run the following Transact-SQL SELECT statements:

You must avoid table scans when you run the queries.
You need to create one or more indexes for the table.
Solution: You run the following Transact-SQL statement:

You need to create a stored procedure that updates the Customer, CustomerInfo, OrderHeader, and
OrderDetails tables in order.You need to ensure that the stored procedure:
Runs within a single transaction.
Commits updates to the Customer and CustomerInfo tables regardless of the status of updates to the
OrderHeader and OrderDetail tables.
Commits changes to all four tables when updates to all four tables are successful.
Solution: You create a stored procedure that includes the following Transact-SQL segment:

You have a database that contains a table named Employees. The table stores information about the
employees of your company.
You need to implement and enforce the following business rules:
Limit the values that are accepted by the Salary column.
Prevent salaries less than $15,000 and greater than $300,000 from being entered.
Determine valid values by using logical expressions.
Do not validate data integrity when running DELETE statements.
Solution: You implement a check constraint on the table.

You are developing a new application that uses a stored procedure. The stored procedure inserts thousands of
records as a single batch into the Employees table.
Users report that the application response time has worsened since the stored procedure was updated. You
examine disk-related performance counters for the Microsoft SQL Server instance and observe several high
values that include a disk performance issue. You examine wait statistics and observe an unusually high
WRITELOG value.
You need to improve the application response time.
Solution: You update the application to use implicit transactions when connecting to the database.
