Here’s a short tutorial on how to get started with Oracle:
- Install the Oracle Database software on your computer or set up an Oracle cloud account.
- Connect to the Oracle Database using the SQLPlus command-line interface. On a Windows machine, you can start SQLPlus by opening the “Start” menu and searching for “SQL*Plus.”
- Log in to the Oracle database using your username and password.
- Once you are logged in, you can start using SQL commands to interact with the database. For example, you can use the following command to create a new table named “employees”:
CREATE TABLE employees (id NUMBER PRIMARY KEY, name VARCHAR2(50), salary NUMBER);
- You can insert data into the “employees” table using the following command:
INSERT INTO employees (id, name, salary) VALUES (1, 'John Doe', 50000); INSERT INTO employees (id, name, salary) VALUES (2, 'Jane Doe', 55000);
- You can retrieve data from the “employees” table using the following command:
SELECT * FROM employees;
- You can update data in the “employees” table using the following command:
UPDATE employees SET salary = 60000 WHERE id = 1;
- You can delete data from the “employees” table using the following command:
DELETE FROM employees WHERE id = 2;
This is just the tip of the iceberg when it comes to working with Oracle Database. With these basic commands, you should be able to perform simple operations such as creating tables, inserting, retrieving, updating, and deleting data. To learn more about working with Oracle, you can consult the Oracle documentation or take an online course to learn more advanced concepts and techniques.
