[sql] xact_abort가 켜져있을 때 SQL Server가 raiserror 후 계속 실행되는 이유는 무엇입니까?

try / catch 블록을 사용하는 경우 심각도가 11-19 인 raiserror 오류 번호로 인해 실행이 catch 블록으로 점프합니다.

16 이상의 심각도는 시스템 오류입니다. 다음 코드를 보여주기 위해 try / catch 블록을 설정하고 실패 할 것으로 가정하는 저장 프로 시저를 실행합니다.

오류를 저장할 테이블 [dbo]. [Errors]가 있다고 가정합니다. 실행시 실패 할 저장 프로 시저 [dbo]. [AssumeThisFails]가 있다고 가정합니다.
