BatchUpdateException

Question

hello, there:
I was running an jdbc-related app, and I used preparedStatement.addBatch in this app to insert data into database.
it was fine but today I got an exception: java.sql.BatchUpdateException: Overflow Exception trying to bind NaN
Anyone knows what causes this kind of Exception and how I can solve this problem?
Thanks a lot,
Sway

It looks like you did some bad arithmetic, resulting in a "Not A Number" (NaN) result. For example:
public class Nan {
   public static void main(String[] args) {
      float nan = 0f / 0f;
      System.out.println(nan);
}When you then try to store that value in a floating point column, the database complains. So the problem is in your Java logic, and the database is trying to prevent you from corrupting the column!
It's not specific to the BatchUpdate, it just happened to occur in one, and so the BatchUpdate had to report the error.
