All,

I have very simple two questions..

How can we 'describe a table' and 'view all available tables' in postgres
DB??

I am looking for something similar to 'desc <TABLE>' and 'show tables' in
MySQL or
'desc <TABLE>' and 'select * from tab' in Oracle..

Thanks in advance for your help..

Niral

easily.

psql#> \d table_name
for a specific table

psql#> \d
for all tables

and \? for other useful stuff with backslashes.

Hi, there,

in psql use

\d tablename

BTW

you can use
\? to list all related command

If you are using the psql app, \d will show you all relations (tables,
sequences, etc). \dt will show all tables, \dt <table> will show the
details of a particualr table. See the online help \? for more info.

If we all work together, we can totally disrupt the system.

\d tablename
\dt --- list all tables
\dv --- list all views

In psql:

\d lists all tables
\d table lists all columns in a table

use \? for help on psql commands and \h for help on SQL commands

Start psql with -E to see the SQL queries that \d produces.
