Hello All, I just wanted to know whether there are any known issues in defining and using Foreign key constraints in MySQL 4 and MySQL 5. To be specific, are there any issues on using ON DELETE CASCADE and ON UPDATE CASCADE?
Would there be any performance issues when we define Foreign key constraints? We dont define Foreign Key constraints here. But at the conceptual level we know that there are foreign keys. But we do not create foreign keys at the physical level. Is this right? Thanks & Regards, Ratheesh
