When I do a insert in oracle with the properties in the hibernate-mapping
that doesnt have the same order as the fields of the table in the DB and there are date fields with time, it inserts wrong data in some fields

example of inserts ( the 'X' value chenged to '

Don't clearly understand your problem, but I'm inclined not to believe you (especially the <property> move leading to an error).

well, when I first saw it I couldn't believe neither, I spend some days trying to understand whats going on but I saw it happen.

I change de property tag from one place to another and the data inserted changed to some strange characters (this just happen if you have a date field and try to insert date and time in that field)

I think is something in the oracle configuration that the DBA changed that produce that error but I'm not sure.

I know its not the driver cause I made a insert using preparedstatement and it ran OK.

This is definitely not a problem with Hibernate.

why hibernate insert wrong data when changing the properties tags order ?

the DBA claims that he didn't change anything, I'm inclined to believe him because the error happens in production server as well as in development server, and he didn't changed anything in production server.

I suspect some strange character encoding problems ... definately not a Hibernate issue.
