title: Get oracle sequenve next value without change it
body: <p>I have a big problem. I need to know the next value of an oracle sequence without changing it.</p>
  
  <p>If I use <code>sequence.NEXTVAL</code> , I get what I need. The problem is that the value changed, so the next record will get this value + 1 and it's not good for me.</p>
  
  <p>I know I can use <code>sequence.CURRVAL</code> and it's great because it does not change the value, but in case of no records, it's not working and in this case the sequence value can be any number (and not only 1 cause the sequence value steel exist).</p>
  
  <p>Please help me to find a solution.</p>
  
  <p>Thank you vary much !!!!!</p>
