Exam 70-465 topic 1 question 35 discussion

You are building a stored procedure for a Windows Azure SQL Database. The procedure will add multiple rows to a table.
You need to design the stored procedure to meet the following requirements:
If any of the new rows violates a table constraint, then no further additions must be attempted and all changes made by the stored procedure must be discarded.
If any errors occur, a row must be added to an audit table, and the original error must be returned to the caller of the stored procedure.
What should you include in the design?
