i still dont see any reason WHY should i do not do this?
the disadvantage is, the DB will update the same col. twice :)

I'm not so sure: EOF might not use the same transaction for getting the key number as you are - so then a likely scenario is

- EOF gets a PK (30) from EO_PK_TABLE or whatever, which is currently the highest PK (29) + 1 - other code directly inserts an object, commits, the highest PK is now 30 - you insert: bang, tried to insert duplicate PK

So the only real way to do this is to use the *same* means for generation for all or at least disable concurrent access.

Cheers, Anjo
