Introducing SQL*Plus 1

Who Can Use SQL*Plus?
The SQL*Plus, SQL, and PL/SQL command languages are powerful enough to serve the needs of users with some database experience, yet straightforward enough for new users who are just learning to work with Oracle.

The design of the SQL*Plus command language makes it easy to use. For example, to give a column labelled ENAME in the database the clearer heading "Employee", you might enter the following command:
COLUMN ENAME HEADING EMPLOYEE
Similarly, to list the column definitions for a table called EMP, you might enter this command:
DESCRIBE EMP
