Here's simple query, to list which table's which columns references to a
specific table. (Hope this is what you asked for.)
SELECT TBL.table_name, COL.column_name FROM information_schema.referential_constraints AS REF INNER JOIN
information_schema.table_constraintsAS TBL USING (constraint_name) INNER JOIN
information_schema.constraint_column_usageAS COL USING (constraint_name) INNER JOIN
information_schema.table_constraintsAS PRI ON (PRI.constraint_name = REF.unique_constraint_name) WHERE
PRI.table_name= 'pri_id'; -- Your target table goes here.
This is a quick & dirty hack. Just wanted to show the possibility of the
idea using information schema. (You don't want to deal with internal
tables, ain't?)
Regards.
