pgAdmin 中的临时表

发布于 2024-10-30 03:17:36 字数 160 浏览 1 评论 0原文

我在 Postgres 8.4 数据库中使用 pgAdmin,我想知道在哪里(任何表/架构/等?)可以找到当前使用的临时表的列表?我想一定有一个地方可以找到它。

它们不存在于目录对象中,也不存在于视图中,还有其他建议吗?

I am using pgAdmin for my Postgres 8.4 database and I was wondering where (any table/schema/etc. ?) may I find a list of currently used temporary tables? I assume there has to be a place where I can find it.

They are not present in a catalog object tables nor in views, any other suggestions?

临时表存在于临时模式 pg_temp_{№} 中,默认情况下隐藏在 pgAdmin UI 中。

在 pgAdmin(至少 pgAdmin4)中,您可以打开首选项窗格并打开此设置:

显示 -> 显示系统对象?True

这将显示您创建的隐藏架构临时表。

PS 更改首选项后刷新架构树

Temporary tables live in temporary schemas pg_temp_{№} that hidden by default in pgAdmin UI.

In pgAdmin(pgAdmin4 at least) you can open preferences pane and switch on this setting:

Display->Show system objects? to True

This will show hidden schemas with your created temp tables.

PS After changing preference refresh schema tree

Postgres 为名为“pg_temp_#”的临时表创建一个临时模式,您可以使用 psql 查看它...

create temp table mytemptable(name varchar);

select c.relname
from pg_namespace n
  join pg_class   c on n.oid=c.relnamespace
where n.nspname='pg_temp_1';

您可以列出在 psql 中执行“\dn”的模式。

希望有帮助。

Postgres creates a temporary schema for temporary tables named "pg_temp_#", you can see it with psql...

create temp table mytemptable(name varchar);

select c.relname
from pg_namespace n
  join pg_class   c on n.oid=c.relnamespace
where n.nspname='pg_temp_1';

You can list your schemas executing "\dn" in psql.

Hope that helps.

在 pgAdmin 4 中你只需要启用

属性->浏览器->显示->显示系统对象

(从底部开始第一个)。之后你就可以在里面找到你的桌子了

pg_temp_(#) 架构

In pgAdmin 4 you just need to enable in

Properties -> Browser -> Display -> Show system objects

(this one first from the bottom). After this you would be able to find your table inside

pg_temp_(#) schema

SELECT
    n.nspname as SchemaName
    ,c.relname as RelationName
    ,CASE c.relkind
    WHEN 'r' THEN 'table'
    WHEN 'v' THEN 'view'
    WHEN 'i' THEN 'index'
    WHEN 'S' THEN 'sequence'
    WHEN 's' THEN 'special'
    END as RelationType
    ,pg_catalog.pg_get_userbyid(c.relowner) as RelationOwner               
    ,pg_size_pretty(pg_relation_size(n.nspname ||'.'|| c.relname)) as RelationSize
FROM pg_catalog.pg_class c
LEFT JOIN pg_catalog.pg_namespace n               
                ON n.oid = c.relnamespace
WHERE  c.relkind IN ('r','s') 
AND  (n.nspname !~ '^pg_toast' and nspname like 'pg_temp%')
ORDER BY pg_relation_size(n.nspname ||'.'|| c.relname) DESC

将显示所有临时表的输出。

Will show you output of all temporary tables.
