Referential Integrity in a Shared Table

1
Hi Guys,

Partially random question... Lets say you have a phone numbers table structured as such:

numberId
tableId
recordId
number

Where tableId is the Id of the source table, recordId is the Id of the source record in the source table and numberId is the PK of the numbers table...

Assuming that the tableId is only used in queries and is not explicitly defined as a field in the parent table, how would you enforce referential integrity and / or is this possible?

Cheers.
