hi,

i want to insert a date in my oracle database but i want it to be automatic (ie when the object is saved in database the column "creation_date" is filled with the current date).

can we configure this in mapping files ? i have the same issue with the column "modification_date".

thank you !

As far as I know, You could not dot it using mapping files.
But you can use triggers or somethig else on DB side.
Also you can fill date prorties in constructor of you class.

For the "modification_date" column it should be possible to use the <timestamp> mapping (see http://www.hibernate.org/hib_docs/v3/re ... -timestamp).

As a side effect this also enables versioning using optimistic locking, which may or may not be desired.

Another option is to implement an Interceptor. See http://www.hibernate.org/hib_docs/v3/re ... vents.html which contains an example that is more or less identical to your case.
