title: what are the differences between using "BETWEEN" operator and "<= and >= " (arithmetic) operators?
body: <p>I am learning oracle database specifically Oracle 11g. And came across a doubt that the same functionalities could be achieved when we are using &quot;BETWEEN&quot; operator and &quot;&lt;= AND &gt;=&quot; (Arithmetic Operators)&quot; for ex:</p>
  <p>SQL&gt; select employee_id , first_name , salary from employees where salary between 10000 and 15000;</p>
  <p>is giving the same output as</p>
  <p>SQL&gt; select employee_id , first_name , salary from employees where salary &gt;=10000 and salary &lt;=15000;</p>
  <p>Could you guys please help me understand what are the differences here.</p>
