title: On cascade in SQL/Oracle
body: <p>How can I do <code>on Update Cascade</code> in Oracle? I read that this is not possible. It is allowed in mysql or plsql. But how can make the same in Oracle?</p>
  
  <p>example:</p>
  
  <pre><code>create table section(
  id int not null primary key );
  
  Create table student(
  id int not null primary key,
  name varchar2(30),
  numSec int not null,
  Constraint fk_section Foreign key(numSec) references section(id) ON UPDATE CASCADE);
  </code></pre>
