Обсуждение: how to list all tables in a database

Hello all,

this is my first question... I'm really new to PG.

How do I get a list of all tables in a database ?

Is there an SQL command for this ?

thx

Bom Dia!  Bemvindo ao Pg.

In psql, type:

\dt

Look at the chapter from the manual here:

http://www.postgresql.org/docs/8.1/static/view-pg-tables.html

As a starter, you can do:

select * from pg_tables;

If you are using psql then simply \dt

Or the SQL query that is performed by \dt is

SELECT n.nspname as "Schema",
  c.relname as "Name",
  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 "Type",
  u.usename as "Owner"
FROM pg_catalog.pg_class c
     LEFT JOIN pg_catalog.pg_user u ON u.usesysid = c.relowner
     LEFT JOIN pg_catalog.pg_namespace n ON n.oid = c.relnamespace
WHERE c.relkind IN ('r','')
      AND n.nspname NOT IN ('pg_catalog', 'pg_toast')
      AND pg_catalog.pg_table_is_visible(c.oid)
ORDER BY 1,2;

Cheers

Depends. In psql you can type '\t' (without ') to see all tables. Hint:
read the welcome-message, when you start psql. *wink*

If you want to see the complete underlaying SQL, you should start psql
with the option '-E'. For more info: man psql *wink*

In the psql terminal
