都内で働くSEの技術的なひとりごと / Technical soliloquy of System Engineer working in Tokyo

都内でサラリーマンやってます。SQL Server を中心としたマイクロソフト系(たまに、OSS系などマイクロソフト以外の技術も...)の技術的なことについて書いています。日々の仕事の中で、気になったことを技術要素関係なく気まぐれに選んでいるので記事内容は開発言語、インフラ等ばらばらです。なお、当ブログで発信、発言は私個人のものであり、所属する組織、企業、団体等とは何のかかわりもございません。ブログの内容もきちんと検証して使用してください。英語の勉強のため、英語の記事も投稿するようにしています。

Started studying Oracle

I haven't posted an article recently. I was busy because my environment has changed. I had used only SQL Server, but now I need to use Oracle at work. ( I had used symfo....lol, too. ) I try to connect Oracle because I can not do anything. I try to connect Oracle, Using tool below.
a5m2.mmatsubara.com

User interface is below.

f:id:koogucc11:20190828174942p:plain
A5:SQL Mk-2

I try to use a little, I think that A5:SQL Mk-2 has many function and useful. I want to get an information about Oracle, I try to find like dmv and dmf in SQL Server. It is V$ table. Execute below query, you will get list of V$.

SELECT
    OBJECT_NAME 
FROM 
    DBA_OBJECTS
WHERE 
    OBJECT_NAME LIKE 'V$%'

f:id:koogucc11:20190828175824p:plain
Getting information from DBA_OBJECTS by using V$

If you want to get information of Executing query in Oracle, execute below query.

SELECT
    vs.sid,
    vsa.sql_text,
    vs.serial#,
    vs.status,
    vs.machine,
    vs.osuser,
    vs.module,
    vs.username,
    vs.process
FROM
    V$SESSION vs,
    V$SQLAREA vsa
WHERE
    vs.prev_hash_value = vsa.hash_value
AND vs.prev_sql_addr = vsa.address
AND vs.status = 'ACTIVE'

f:id:koogucc11:20190921183326p:plain
execution result

Something like SQL Server's sys _exec_requests (Transact-sql) - SQL Server | Microsoft Docs and sys.dm_exec_sql_text (TRANSACT-SQL) - SQL Server | Microsoft Docs

 There are many function of V$. It is possible to get so many information of Oracle Database.

I bought drive recorder what can be connect by using smart phone. I wonder if it can be connected by using REST API. If it is true, excellent!

My Drive recorder is so expensive. I assume that there are more cheaper and having good features drive recorder.
