Question

I have a table containing a foreign key and I know the column name of that foreign key.

Is it possible, using this information, to determine the table to which that key links?

The reason for this is that the foreign key is dynamic and so I cannot determine the linked table in advance.

Provided you are using MySQL 5.1 or later, you can use REFERENTIAL_CONSTRAINTS table from information schema. Something like:

select references_table_name
  from referential_constraints
 where table_name = 'your_table';
