Hi
My name is Hoo.
I got the data from Oracle DB by getBigDecimal() method.
When the value in DB is null, I don't want to output anything into
TextField.
But always output 0.  How does null become 0?
I even tested as follows..

dataquerySet.setBigDecimal("cost",null);
if (dataquerySet.getBigDecimal("cost") == null )
  System.out.println("null");

But the process doesn't go inside of if block.
Please tell me what's worng.
Thank you.
