What's the equivalent to show tables (from MySQL) in PostgreSQL?

From the psql command line interface,
First, choose your database
\c database_name Then, this shows all tables in the current schema:
\dt Programmatically (or from the psql interface too, of course):
SELECT * FROM pg_catalog.pg_tables; The system tables live in the pg_catalog database.
Login as superuser:
sudo -u postgres psql You can list all databases and users by \l command, (list other commands by \?).
Now if you want to see other databases you can change user/database by \c command like \c template1, \c postgres postgres and use \d, \dt or \dS to see tables/views/etc.
You can use PostgreSQL's interactive terminal Psql to show tables in PostgreSQL.
1. Start Psql
Usually you can run the following command to enter into psql:
psql DBNAME USERNAME For example, psql template1 postgres
One situation you might have is: suppose you login as root, and you don't remember the database name. You can just enter first into Psql by running:
sudo -u postgres psql In some systems, sudo command is not available, you can instead run either command below:
psql -U postgres psql --username=postgres 2. Show tables
Now in Psql you could run commands such as:
\?list all the commands\llist databases\conninfodisplay information about current connection\c [DBNAME]connect to new database, e.g.,\c template1\dtlist tables of the public schema\dt <schema-name>.*list tables of certain schema, e.g.,\dt public.*\dt *.*list tables of all schemas- Then you can run SQL statements, e.g.,
SELECT * FROM my_table;(Note: a statement must be terminated with semicolon;) \qquit psql
(For completeness)
You could also query the (SQL-standard) information schema:
SELECT table_schema || '.' || table_name FROM information_schema.tables WHERE table_type = 'BASE TABLE' AND table_schema NOT IN ('pg_catalog', 'information_schema'); First login as postgres user:
sudo su - postgresconnect to the required db:
psql -d databaseName\dtwould return the list of all table in the database you're connected to.
Login as a superuser so that you can check all the databases and their schemas:-
sudo su - postgres Then we can get to postgresql shell by using following command:-
psql You can now check all the databases list by using the following command:-
\l If you would like to check the sizes of the databases as well use:-
\l+ Press q to go back.
Once you have found your database now you can connect to that database using the following command:-
\c database_name Once connected you can check the database tables or schema by:-
\d Now to return back to the shell use:-
q Now to further see the details of a certain table use:-
\d table_name To go back to postgresql_shell press \q.
And to return back to terminal press exit.
Running psql with the -E flag will echo the query used internally to implement \dt and similar:
sudo -u postgres psql -E postgres=# \dt ********* QUERY ********** 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", pg_catalog.pg_get_userbyid(c.relowner) as "Owner" FROM pg_catalog.pg_class c LEFT JOIN pg_catalog.pg_namespace n ON n.oid = c.relnamespace WHERE c.relkind IN ('r','') AND n.nspname <> 'pg_catalog' AND n.nspname <> 'information_schema' AND n.nspname !~ '^pg_toast' AND pg_catalog.pg_table_is_visible(c.oid) ORDER BY 1,2; ************************** If you only want to see the list of tables you've created, you may only say:
\dt
But we also have PATTERN which will help you customize which tables to show. To show all including pg_catalog Schema, you can add *.
\dt *
If you do: \?
0\dt[S+] [PATTERN] list tables
use only see a tables
=> \dt if want to see schema tables
=>\dt+ if you want to see specific schema tables
=>\dt schema_name.* If you are using pgAdmin4 in PostgreSQL, you can use this to show the tables in your database:
select * from information_schema.tables where table_schema='public'; First Connect with the Database using following command
\c database_name And you will see this message - You are now connected to database database_name. And them run the following command
SELECT * FROM table_name; In database_name and table_name just update with your database and table name
1Note that \dt alone will list tables in the public schema of the database you're using. I like to keep my tables in separate schemas, so the accepted answer didn't work for me.
To list all tables within a specific schema, I needed to:
1) Connect to the desired database:
psql mydb 2) Specify the schema name I want to see tables for after the \dt command, like this:
\dt myschema.* This shows me the results I'm interested in:
List of relations Schema | Name | Type | Owner ----------+-----------------+-------+---------- myschema | users | table | postgres myschema | activity | table | postgres myschema | roles | table | postgres select * from pg_catalog.pg_tables where schemaname != 'information_schema' and schemaname != 'pg_catalog'; \dt (no * required) -- will list all tables for an existing database you are already connected to. Also useful to note:
\d [table_name] -- will show all columns for a given table including type information, references and key constraints.
You can list the tables in the current database with \dt.
Fwiw, \d tablename will show details about the given table, something like show columns from tablename in MySQL, but with a little more information.
The most straightforward way to list all tables at command line is, for my taste :
psql -a -U <user> -p <port> -h <server> -c "\dt" For a given database just add the database name :
psql -a -U <user> -p <port> -h <server> -c "\dt" <database_name> It works on both Linux and Windows.
Those steps worked for me with PostgreSQL 13.3 and Windows 10
- Open cmd and type
psql -a -U [username] -p [port] -h [server] - Type
\c [database]to connect to the database - Type
\dtor\dto show all tables
\dt will list tables, and \pset pager off shows them in the same window, without switching to a separate one. Love that feature to death in dbshell.
Using psql : \dt
Or:
SELECT c.relname AS Tables_in FROM pg_catalog.pg_class c LEFT JOIN pg_catalog.pg_namespace n ON n.oid = c.relnamespace WHERE pg_catalog.pg_table_is_visible(c.oid) AND c.relkind = 'r' AND relname NOT LIKE 'pg_%' ORDER BY 1 This SQL Query works with most of the versions of PostgreSQL and fairly simple .
select table_name from information_schema.tables where table_schema='public' ; First of all you have to connect with your database like
my database is ubuntu
use this command to connect
\c ubuntu This message will show
"You are now connected to database "ubuntu" as user "postgres"."
Now
Run this command to show all tables in it
\d+ as a quick oneliner
# just list all the postgres tables sorted in the terminal db='my_db_name' clear;psql -d $db -t -c '\dt'|cut -c 11-|perl -ne 's/^([a-z_0-9]*)( )(.*)/$1/; print' or if you prefer much clearer json output multi-liner :
IFS='' read -r -d '' sql_code <<"EOF_CODE" select array_to_json(array_agg(row_to_json(t))) from ( SELECT table_catalog,table_schema,table_name FROM information_schema.tables ORDER BY table_schema,table_name ) t EOF_CODE psql -d postgres -t -q -c "$sql_code"|jq In PostgreSQL command-line interface after login, type the following command to connect with the desired database.
\c [database_name]
Then you will see this message You are now connected to database "[database_name]"
Type the following command to list all the tables.
\dt
(MySQL) shows tables list for current database
show tables; (PostGreSQL) shows tables list for current database
select * from pg_catalog.pg_tables where schemaname='public'; shows tables list for current database
SELECT * FROM pg_catalog.pg_tables;
To view foreign tables in psql, run \dE
First you can connect with your postgres database using the postgre.app on mac or using postico. Run the following command:
psql -h localhost -p port_number -d database_name -U user_name -W then you enter your password, this should give access to your database
