I think this is a simple question, but how do i check which table a foreign key refers to in mysql?

If i use describe tablename then i can see there is a key, but not sure what its refering to. I just want to verify i correctly mapped this in hibernate.

mysql> describe attendedlistent_userent;

You can get at this sort of data by querying the database's catalog directly (refer to the MySQL documentation for the appropriate tables) or a better way is to query the DatabaseMetaData (this way your solution is not tied to one database version).

Hi Ilya,

That's database specific though, it won't work on all systems. Paul's suggestion of using the JDBC meta data classes is preferable if you're implementing the method as part of a code base. For example, if you need to check from within the application while its running.
