But Updates are not possible either if dependent rows exist. Sitz: Düsseldorf, Handelsregister: Amtsgericht Düsseldorf, HRB 37996 -----Ursprüngliche Nachricht----- Von: DB2 Data Base Discussion List [mailto:[login to unmask email] Im Auftrag von Darren Kilpatrick Gesendet: Donnerstag, 15.

I think, you have to insert these rows into the parent table, update the foreign key in the dependent tables and then delete the old rows in the parent table.

Just follow Best Practices outlined by an authority in the subject matter and things will magically fall into place.

Rather than just focus on Best Practices, I would like to propose that one should think about what they are trying to achieve and why one approach is better than another to get there.In this section, we will talk about considerations on a very elemental functional level rather than a more macro application level.We think it is important to consider each functional task of an application separately rather than thinking of an application as a whole.You will often hear the term Best Practices used in Application Architecture.The danger of such a term is that it gives one a sense that there is no need to question a practice because it is always best.CREATE TABLE country( name VARCHAR(100) NOT NULL, population BIGINT, PRIMARY KEY(name) ); CREATE TABLE city( name VARCHAR(100) NOT NULL, country VARCHAR(100) NOT NULL, PRIMARY KEY(name), FOREIGN KEY(country) REFERENCES country(name) ); And here is my problem: DB2 doesn't support "ON UPDATE CASCADE" and still referenced primary keys aren't allowed to change.
