Re: Inherited FK Indexing

Hi,

as expected I can do select * from states and get everything out of the child table as well. What I can't do is create a FK to the states table and have it look in the child table as well. Is this on purpose? Is it possible to have FK that spans into child tables?

This is a well known (and documented, see [1]) deficiency. It's due to the current implementation of indices, which are bound to exactly one table, meaning they do return a position within the table, but cannot point to different tables.
