title: Sequence increment by 50 instead of 1
body: <p>I created an Oracle sequence: </p>
  
  <p>Create sequence seq_acteurs start with 1 increment by 1;</p>
  
  <p>Normally the sequence must be incremented by 1, but when insert into <code>Acteurs</code> table, the sequence <code>s</code> incremented by 50! That doesn't seem logical. Why is this so?</p>
  
  <p>Any help will much apreciated.</p>
