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.

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.

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.
