If you don't like the command line interface offered by SQL*Plus, you can use the Web interface to run SQL statements. Here is how:

► Open your Web browser to http://localhost:8080/apex/

► Log in to the server with the predefined sample user account: HR/globalguideline

► Click the SQL icon

► Click the SQL Commands icon

► Enter any SQL statement like: "SELECT COUNT(*) FROM USER_TABLES;", in the text area and click Run button

► Your Oracle will execute the statement, and display the result in the result area.
