You need to ensure that a stored procedure fails if an INSERT statment within the stored procedure fails. What action should you take?

THROW raises an exception programmatically but does not automatically ensure transaction rollback for all types of run-time errors that an INSERT statement might encounter unless explicitly handled in a CATCH block.

SET XACT_ABORT OFF means that if a T-SQL statement raises a run-time error, the transaction might not be rolled back entirely, and execution could continue, which is the opposite of the desired behavior.

SET XACT_ABORT ON ensures that if a T-SQL statement, such as an INSERT, within an explicit or implicit transaction encounters a run-time error, the entire transaction is automatically rolled back and the batch is terminated. This behavior guarantees that the stored procedure fails completely if the INSERT statement fails.

TRY...CATCH blocks are used for error handling and allowing recovery or custom error actions, but they do not inherently guarantee that an entire transaction will be rolled back upon an INSERT failure without explicit ROLLBACK TRANSACTION statements within the CATCH block.
