You are developing an application to track customer sales.
You need to create a database object that meets the following requirements:
- Return a value of 0 if data inserted successfully into the Customers table.
- Return a value of 1 if data is not inserted successfully into the Customers table.
- Support TRY"¦CATCH error handling
- Be written by using Transact-SQL statements.
What should you create?

Answer options

• A. extended procedure
• B. CLR procedure
• C. user-defined procedure
• D. DML trigger
• E. scalar-valued function
• F. table-valued function

Correct answer: D

Explanation

The correct answer is D, a DML trigger, because it can automatically execute upon data modification events, such as insertions. The other options, such as extended procedures, CLR procedures, and functions, do not inherently support automatic execution on data changes and do not fulfill the specified requirements for error handling and return values.
