This question/answer should give you the details you need:
Get list of all tables in Oracle?
but in summary...
-- If you have access
SELECT owner, table_name
FROM dba_tables
-- Will show what your user has access to
SELECT owner, table_name
FROM all_tables
SHOW TABLES IN `db`;
Where db is the name of your database.

I want to retrieve all table names and column names IN A SCHEMA. So if I am in schema scott it should only show all the tables present in scott.
And can the query below only retrieve the tables in a schema?
Select * from tab;
select *
from all_tab_columns
where owner = 'SCOTT'
More details in the manual: http://docs.oracle.com/cd/E11882_01/server.112/e25513/statviews_part.htm#i125539
This query should work:
SELECT *
FROM INFORMATION_SCHEMA.COLUMNS

The employee table is what I am trying to display from.
To list all columns for a specific table:
select column_name, data_type
from all_tab_columns
where table_name = 'EMPLOYEES';
More details in the manual: http://docs.oracle.com/cd/E11882_01/server.112/e25513/statviews_2103.htm#I1020277
If you are using SQL*Plus you can simply run
desc EMPLOYEES
instead.
Most other SQL clients have a similar feature.

Hi all,
I have 30 tables in my database, in some of tables i have a common column, assume 'eno'. How can i find the tables of 'eno'. Thank you...

FROM information_schema.columns
WHERE column_name = 'eno'
