Postgres sql列出數據庫中的所有表格

Question

「psql \ dt information_schema」我正在編寫此命令以查看所有表及其詢問的列表「」用戶information_schema的密碼：「」我應該提供哪個密碼，I meadn I m提供postgres作爲密碼。

Answer 1

你用下面的命令做什麼：

psql \dt information_schema 

是啓動PSQL並通過名爲「INFORMATION_SCHEMA」作爲用戶名與連接。

必須輸入\dt information_schema命令後您已經啓動psql並且您看到psql提示符後。

如果您想直接在命令行中運行，而無需等待psql的提示，則需要使用-c開關：

psql -c "\dt information_schema.*" postgres postgres 

所有參數和他們預計的排列順序當您運行psql --help或看看手冊：

下面是一個簡單的控制檯會話將告訴您如何做到這一點：

 
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 
--------------------+-----------------------------------+------+--------- 
information_schema | _pg_foreign_data_wrappers   | view | postgres

這裏是如何做到這一點的一個電話：

 
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_packages   | table | postgres 
information_schema | sql_parts    | table | postgres 
information_schema | sql_sizing    | table | postgres 
information_schema | sql_sizing_profiles  | table | postgres
