Since we had a problem with this row , we updated it and I do not have the value in date_ouverture which gave a problem.

However , we identified the source of the problem.

This value was updated using java.

The value which was entered was 27/01/20055.

What I do not unterstand is that Oracle found a way to enter the value in the colum but can not make any operation on it.
