i'm using powerdesinger 7.5. i'm generating ddl for mysql 3.22. under the "generate database" option, in the "keys & indexes" tab, i have "create foreign key" option checked. it doesn't seem to generate any foreign key ddl for me. when i change the database to oracle 8.1.7, i get the foreign key definitions. i'm wondering if this is an annoying bug in mysql ddl generation. thanks.
