Hi all, How can I have indexes/constraints info? I tried to delete a row from a table in my db and I got this message: (IntegrityError) ORA-02292: integrity constraint (SFERA.SYS_C0057216) violated - child record found I can't realize what SYS_C0057216 is and to what it is linked. I would like to know how to have information about it. Is there a way to do that? thanks for any help. j -- //www.freelists.org/webpage/oracle-l
