Hi, Should I or shouldn't I explicitly specify the foreign key in Mysql? If I am not mistaken, Mysql handles foreign keys automatically at query time and we need not explicitly specify the foreign key.
But, will the database detect error when I enter non-existent value for a foreign key? Do I need to explicitly specify foreign key when creating table? If I have to, can I use Alter table to modify table that has been already created? Thanks, Sanjay Chigurupati __________________________________________________ Do You Yahoo!? Try FREE Yahoo!
