I want to drop a table but it is referenced by one or more other tables. How can I find out which tables are referencing this table without having to look at each of the tables
Use Toad to load it up and you can view the references through the diagram. also make sure that you don't have any app code passing sql from the front-end, dropping the table may cause the app to break.

If you are using innoDB try this one SHOW TABLE STATUS FROM yourdatabasename LIKE 'T' http://dev.mysql.com/doc/refman/5.1/en/show-table-status.html
