SQL Developer - HR 계정 생성하기

SQL Developer - HR 계정 생성하기

 

시스템 계정에 로그인하고

sql 워크시트를 열어서 hr 이라는 이름으로 사용자 생성해준다

 

hr 계정 생성

CREATE USER hr identified by hr;
GRANT CREATE TABLE TO hr;
GRANT CONNECT, RESOURCE, DBA TO hr;
GRANT CREATE ANY TABLE TO hr;
grant CREATE SESSION TO hr;

생성에 성공하고 접속 새로고침을 하면

HR 사용자가 생성된 것을 확인 할 수 있다

 

그리고 hr 계정에 접속해서

연습용 테이블을 넣어준다
