openGauss每日一练第5天 - 学习心得体会

课程作业

测试环境准备：

su - omm
gsql -r

1.创建数据库musicdb10，创建用户user10，赋予sysadmin权限

drop DATABASE  IF EXISTS  musicdb10;
drop tablespace IF EXISTS music_tbs;

CREATE TABLESPACE music_tbs RELATIVE LOCATION 'tablespace/test_ts1';
CREATE DATABASE musicdb10  WITH TABLESPACE = music_tbs;

 CREATE USER user10 IDENTIFIED BY 'kunpeng@1234';
ALTER USER user10 SYSADMIN;

2.用户user10访问数据库postgres，创建一个表并插入数据

omm=#  \c postgres user10
Password for user user10: 
Non-SSL connection (SSL connection is recommended when requiring high-security)
You are now connected to database "postgres" as user "user10".
openGauss=> 

openGauss=>  create table t21(col1 char(20));
CREATE TABLE
openGauss=>  insert into t21 values('Hello openGauss! 22');
INSERT 0 1
openGauss=>  select * from t21;
openGauss=>          col1         
----------------------
 Hello openGauss! 22 
(1 row)

3.用户user10访问数据库omm，创建一个表并插入数据

openGauss=> \c  omm user10
Password for user user10: 
Non-SSL connection (SSL connection is recommended when requiring high-security)
You are now connected to database "omm" as user "user10".
omm=> create table t31(col1 char(20));
CREATE TABLE
omm=>  insert into t31 values('Hello openGauss! 33');
INSERT 0 1
omm=>  select * from t31;
         col1         
----------------------
 Hello openGauss! 33 
(1 row)

4.用户user10访问数据库musicdb10，创建一个表并插入数据

omm=> \c musicdb10 user10
Password for user user10: 
Non-SSL connection (SSL connection is recommended when requiring high-security)
You are now connected to database "musicdb10" as user "user10".
musicdb10=> create table t21(col1 char(20));
CREATE TABLE
musicdb10=>  insert into t21 values('Hello openGauss! 22');
INSERT 0 1
musicdb10=>  select * from t21;
         col1         
----------------------
 Hello openGauss! 22 
(1 row)
