Oracle Tutorial - How to add virtual column in oracle 11g
 
07:41
Hello friends in this video i'm going to demonstrate you how to add virtual column in ORACLE 11g step by step. Oracle 11g supports virtual columns which are derived from the other columns in the table. You can use the virtual columns in your queries, you can index them, you can collect the statistics, etc. There are few restrictions on the virtual columns. You cannot write/insert the data into virtual columns. There is no support for index_organized, external, object, cluster, temporary tables.

TSQL: Find Unused Tables

I applaud the author of the article for looking at this, as it's challenging. I would be very careful though before making some of the assumptions; we want to be sure that something is unused, and we should always have discussions with application developers to make sure we don't disrupt what they're doing.

강의 자료(PDF) 다운로드: https://goo.gl/VZovDV 칼럼 제거 - 칼럼 제거 시 SET UNUSED COLUMN은 해당 칼럼의 데이터를 물리적으로 삭제하는 것이 아니라 사용하지 않는 칼럼으로 Marking 하는 것이다. DROP UNUSED COLUMNS는 UNUSED로 Marking 된 모든 칼럼들을 DROP 한다. Row Chain & Row Migration - Row Chaining이란 Data Block 하나에 전부 입력할 수 없는 Row가 여러 Block에 걸쳐서 입력되는 것을 말한다. - Row Chain이 발생 하면 Chain이 발생한 Row를 조회 시 하나 이상의 Block에 대해 I/O가 발생하므로 성능을 저하 시키는 요인이 된다. - 이러한 Row Chaining 현상은 해결하기 위해 Row Migration이라는 기법을 이용한다. (일부 저장 용량의 손실을 감수 하더라도...) - Row Migration이란 Block 하나에 전부 입력할 수 없는 Row를 다른 Block으로 옮겨서 입력하는 것을 말한다.
