openGauss每日一练第3天 | 创建数据库、修改数据库属性和删除数据库

1.分别创建名为tpcc1和tpcc2的数据库

create database tpcc1;
create database tpcc2;

2.将tpcc1数据库重命名为tpcc10

alter database tpcc1 rename to tpcc10;

3.分别使用\l和\l+两个元命令查看数据库信息

\l+

\l

4.在数据库tpcc2中创建customer表，字段自定义

 \c tpcc2
Non-SSL connection (SSL connection is recommended when requiring high-security)
You are now connected to database "tpcc2" as user "omm".

create table customer(id int,name varchar(10));

5.删除新创建的数据库

drop database tpcc10;

 \c omm
Non-SSL connection (SSL connection is recommended when requiring high-security)
You are now connected to database "omm" as user "omm".

drop database tpcc2;

6.退出gsql程序

omm=# \q
