Can ref_int be defined with standard SQL at all?

Can anybody please let me know how to set up referential integrity using standard SQL - I don't want to deal with tricks like MS SQL Server 7.X triggers...

So, the bottom line question is: What are the standard SQL statements to
make ref. int. between e.g. the following two relations (Customer_ID is a foreign key in the second table):

(#Customer_ID, Name, Surname) and (#Item_ID, #Customer_ID, Quantity).

Thank you for your answer in advance. D. Trcek Received on Tue Jan 16 2001 - 10:22:13 CET
