Postgresql列出数据库中的所有表

Question

“psql \ dt information_schema”我正在编写此命令以查看所有表的列表及其要求“”用户information_schema的密码：“”我应该提供哪个密码，我meadn我提供了postgres作为密码。

Answer 1

您使用以下命令执行的操作：

psql \dt information_schema

是启动psql并将名称“information_schema”作为要连接的用户名传递。

在启动psql之后，一旦看到psql提示符，就必须输入 命令{/ 1}。

如果要直接从命令行运行它而不等待psql提示符，则需要使用-c开关：

\dt information_schema

当您运行psql -c "\dt information_schema.*" postgres postgres 或查看手册时，会列出所有参数及其预期顺序：

修改

以下是一个示例控制台会话，向您展示如何执行此操作：

c:\>psql postgres postgres
Password for user postgres:
psql (9.0.4)
Type "help" for help.

postgres=# \dt information_schema.*
                        List of relations
       Schema       |          Name           | Type  |  Owner
--------------------+-------------------------+-------+----------
 information_schema | sql_features            | table | postgres
 information_schema | sql_implementation_info | table | postgres
 information_schema | sql_languages           | table | postgres
 information_schema | sql_packages            | table | postgres
 information_schema | sql_parts               | table | postgres
 information_schema | sql_sizing              | table | postgres
 information_schema | sql_sizing_profiles     | table | postgres
(7 rows)

postgres=# \dv information_schema.*
                            List of relations
       Schema       |               Name                | Type |  Owner

这是如何在一次通话中完成的：

c:\>psql -c "\dt information_schema.*" postgres postgres
Password for user postgres:
                        List of relations
       Schema       |          Name           | Type  |  Owner
--------------------+-------------------------+-------+----------
 information_schema | sql_features            | table | postgres
 information_schema | sql_implementation_info | table | postgres
 information_schema | sql_languages           | table | postgres
 information_schema | sql_packages            | table | postgres
 information_schema | sql_parts               | table | postgres
 information_schema | sql_sizing              | table | postgres
 information_schema | sql_sizing_profiles     | table | postgres
