[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-2799) Default Scale value doesn't right

[Henri Tremblay (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-2799?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_28798 ] 

Henri Tremblay commented on HHH-2799:
-------------------------------------

No, it does not. At least with Oracle. You can have only one of these:

Number
Number(p)
Number(p,s)

With a precision of 0, I would expect to have Number generated, not Number(19,2). 
Then if the precision is specified but the scale is some null value (Integer.MAX_VALUE or whatever), I would expect Number(p)
