To execute SQL statements in an Oracle database, you can use either the SQL*Plus tool or the Oracle SQL Developer tool. Here are the brief steps on how to execute SQL statements using these two tools:

  1. Execute SQL statements using SQL*Plus tool.
  2. Open the command prompt window (Windows) or terminal (Mac and Linux).
  3. To connect to the Oracle database, use the following command: sqlplus username/password@hostname:port/service_name. In this command, username is your database username, password is the password, hostname is the database server host name, port is the port number of the database server, and service_name is the service name of the database.
  4. Enter the SQL statement and press Enter to execute.
  5. Execute SQL statements using the Oracle SQL Developer tool.
  6. Open the Oracle SQL Developer tool.
  7. On the connection panel, right-click “Connections” and choose “New Connection”.
  8. Please enter detailed connection information, including username, password, host name, port, and service name.
  9. Click on the “Test” button to test the connection.
  10. Click the “Connect” button to connect to the database.
  11. Enter the SQL statement in the SQL Worksheet panel and click the “Run Statement” button to execute it.

No matter which tool you use, you can execute common SQL statements such as SELECT, INSERT, UPDATE, and DELETE. Make sure you have sufficient permissions to perform the necessary actions, and backup the database before making any changes.
