Simple SQL Example ​

Let’s look at a very simple example to understand how Oracle SQL works:

-- Create a table for employees
CREATE TABLE employees (
  emp_id NUMBER PRIMARY KEY,
  emp_name VARCHAR2(50),
  job_title VARCHAR2(30),
  salary NUMBER
);

-- Insert data into the table
INSERT INTO employees (emp_id, emp_name, job_title, salary)
VALUES (1, 'John Smith', 'Database Admin', 4500);

Once you master SQL basics, you’ll move to PL/SQL, Oracle’s powerful programming extension that lets you automate tasks, write functions, and create smart database logic

Here’s a small PL/SQL example:

BEGIN
  FOR i IN 1..5 LOOP
    INSERT INTO employees (emp_id, emp_name, job_title, salary)
    VALUES (i+10, 'Employee ' || i, 'Developer', 3500);
  END LOOP;
END;
/
