统信下人大金仓终端创建schema和用户

一定要用终端，命令行的方式才够酷。

1、登录数据库

chenqu@chenqu-uos:~$ ksql -h 192.168.0.202 -U system -W 密码 数据库名称
1

如果不记得命令，可以查看帮助

chenqu@chenqu-uos:~$ ksql --help

1.5、查看数据库是否区分大小写

db1=> show case_sensitive;
 case_sensitive 
----------------
 off
(1 row)

1
2
3
4
5
6

这代表不区分大小写吧。默认情况下，人大进仓的数据库是区分大小写的，模式，用户名，全都自动转成大写，十分讨厌。

2、创建用户

db1=# create user zhyj password '密码';
1

3、列出该数据库下的shema

db1=# \dn
1

4、创建新的schema并指定新建的用户zhyj为owner

db1=# create schema zhyj authorization zhyj;
1

5、设置新建用户zhyj的默认schema为新建的schema

db1=# alter user zhyj set search_path to zhyj;
1

6、改用新建用户zhyj登录

db1=# \c db1 zhyj;
1

7、登录进来，看看自己有啥表没有，不出所料，啥都没有。

db1=> \dt
No relations found.
