Answer / ram

select * from tablename
select distinct * from tablename
above two select statements give same output with all
column name and also data
if we want only column name & its details(datatype,sizre)
use

select * from
information_schema.columns where table_name='EMP1'
(or)
select distinct * from
information_schema.columns where table_name='EMP1'

(Here Table name mustbe in single quotes and also capital
letters only)
