I just did an import. After the import I compared the database structure of the source db (where the export was taken from) and the target db (where I did import into).
There's a couple of tables where a few of it's column got NOT NULL after it got imported into the target db (where it did NOT have NOT NULL in the source).
I haven't done very much exporting and importing. Is this common occurence and an someone explain why.
BTW: Verison is 9205.
