To sign on, enter a username of SYSTEM, the password you specified during the install, and then click the LOGIN button. You will then see four icons representing different functionalities: Administra- tion, Object Browser, SQL, and Utilities. To execute SQL, click the SQL icon. You will then see three icons: SQL Commands, SQL Scripts, and Query Builder. If you want to execute a single SQL statement, you can use the SQL Commands icon. This will allow you to execute a single command and see any results. If you enter multiple SQL statements, you can highlight one individual statement and execute only the highlighted portion. To execute a SQL statement in the SQL Commands window, click the RUN button.
